+# Official Sentry Profiling SDK for NodeJS (alpha ⚠️)
+
+[![npm version](https://img.shields.io/npm/v/@sentry/profiling-node.svg)](https://www.npmjs.com/package/@sentry/profiling-node)
+[![npm dm](https://img.shields.io/npm/dm/@sentry/profiling-node.svg)](https://www.npmjs.com/package/@sentry/profiling-node)
+[![npm dt](https://img.shields.io/npm/dt/@sentry/profiling-node.svg)](https://www.npmjs.com/package/@sentry/profiling-node)
+
+## Usage 🔥
+
+```javascript
+import * as Sentry from '@sentry/node';
+import '@sentry/tracing';
+import { ProfilingIntegration } from '@sentry/profiling-node';
+
+Sentry.init({
+  dsn: 'https://7fa19397baaf433f919fbe02228d5470@o1137848.ingest.sentry.io/6625302',
+  debug: true,
+  tracesSampleRate: 1,
+  profilesSampleRate: 1, // Set profiling sampling rate.
+  integrations: [new ProfilingIntegration()]
+});
+```
+
+Sentry SDK will now automatically profile all transactions, even the ones which may be started as a result of using an automatic instrumentation integration.
+
+```javascript
+const transaction = Sentry.startTransaction({ name: 'I will do some work' });
+
+// The code between startTransaction and transaction.finish will be profiled
+
+transaction.finish();
+```
+
+### Environment flags flags
+
+The default mode of the v8 CpuProfiler is kLazyLogging which disables logging when no profiles are active - this is good because it does not add any overhead to the runtime, but the tradeoff is that it results in slow calls to startProfiling (this can exceed couple hundred ms from our tests). You can switch to eager logging which decreases the startup cost for the tradeoff of CPU overhead. You can do so by defining a `SENTRY_PROFILER_LOGGING_MODE` environment variable `eager|lazy` before running your script.
+
+Example of starting a server with eager logging mode.
+
+```javascript
+SENTRY_PROFILER_LOGGING_MODE=eager node server.js
+```
+
+## FAQ 💭
+
+### When should I not use this package
+
+The package is still in alpha stage and we discourage using it in production systems while extensive testing is done. There is a possibility that adding this package may crash your entire node process (even when imported only in worker threads). We would also advise caution if you want to profile high throughput operations as starting the profiler adds some performance overhead and while we do have micro benchmarks to measure overhead, we have yet to properly test this on production system.
+
+### Can the profiler leak PII to Sentry?
+
+The profiler does not collect function arguments so leaking any PII is unlikely unless. We only collect a subset of the values which may identify the device and os that the profiler is running on - this is a smaller subset of the values already collected by the @sentry/node SDK.
+
+The only way to leak PII would be if you are executing code like
+
+```js
+eval('function scriptFor${CUSTOMER_NAME}....');
+```
+
+In that case it is possible that the function name may end up being reported to Sentry.
+
+### Will starting the profiler on main thread automatically profile worker threads too?
+
+No. All instances of the profiler are scoped per thread (v8 isolate). In practice, this means that starting a transaction on thread A and delegating work to thread B will only result in sample stacks being collected from thread A. That said, nothing should prevent you from starting a transaction on thread B concurrently which will result in two independant profiles being sent to the Sentry backend. We currently do not do any correlation between such transactions, but we would be open to exploring the possibilities. Please file an issue if you have suggestions or specific use-cases in mind.
+
+### How much overhead will this profiler add?
+
+From our initial benchmark, it seems that most of the overhead is incurred from a call to startProfiling when no profiles are currently started - this is likely due to the fact that we use [kLazyLogging](https://v8docs.nodesource.com/node-18.2/d2/dc3/namespacev8.html#a7d16026419ddeaa475afc767a935c4cc) as the default option when we initialize the CpuProfiler. In our initial tests when benchmarking a simple express server, profiled requests would incur a performance penalty in the range of ~10ms. It is important to note that while the overhead is added, the majority of it is spent in startProfiling call and it seems that very little of it is actually added to the code executed between start and stop profiling calls.

+Native Abstractions for Node.js
+===============================
+
+**A header file filled with macro and utility goodness for making add-on development for Node.js easier across versions 0.8, 0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18.**

+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a bit more pleasant.

+## News & Updates
+
+<a name="usage"></a>
+
+## Usage
+
+Simply add **NAN** as a dependency in the *package.json* of your Node addon:
+
+``` bash
+$ npm install --save nan
+```
+
+Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
+
+``` python
+"include_dirs" : [
+    "<!(node -e \"require('nan')\")"
+]
+```
+
+This works like a `-I<path-to-NAN>` when compiling your addon.
+
+<a name="example"></a>
+
+## Example
+
+Just getting started with Nan? Take a look at the **[Node Add-on Examples](https://github.com/nodejs/node-addon-examples)**.
+
+Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.

+
+### JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+
+### Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+### Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
+
+### New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

+ - <a href="doc/new.md#api_nan_false"><b><code>Nan::False()</code></b></a>
+ - <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
+
+
+### Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
+
+ - <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
+
+### Maybe Types
+
+The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

+
+### Script
+
+NAN provides `v8::Script` helpers as the API has changed over the supported versions of V8.
+
+ - <a href="doc/script.md#api_nan_compile_script"><b><code>Nan::CompileScript()</code></b></a>
+ - <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
+ - <a href="doc/script.md#api_nan_script_origin"><b><code>Nan::ScriptOrigin</code></b></a>
+
+
+### JSON
+
+The _JSON_ object provides the C++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="doc/json.md#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="doc/json.md#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.
+
+### Errors
+
+NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
+
+Note that an Error object is simply a specialized form of `v8::Value`.
+
+Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

+
+
+### Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+ - <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+### Nan::Callback
+
+`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
+
+ - <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
+
+### Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+
+### Strings & Bytes
+
+Miscellaneous string & byte encoding and decoding functionality provided for compatibility across supported versions of V8 and Node. Implemented by NAN to ensure that all encoding types are supported, even for older versions of Node where they are missing.

+ - <a href="doc/string_bytes.md#api_nan_decode_write"><b><code>Nan::DecodeWrite()</code></b></a>
+
+
+### Object Wrappers

+ - <a href="doc/object_wrappers.md#api_nan_object_wrap"><b><code>Nan::ObjectWrap</code></b></a>
+
+
+### V8 internals
+
+The hooks to access V8 internals—including GC and statistics—are different across the supported versions of V8, therefore NAN provides its own hooks that call the appropriate V8 methods.

+## Known issues
+
+### Compiling against Node.js 0.12 on OSX
+
+With new enough compilers available on OSX, the versions of V8 headers corresponding to Node.js 0.12
+do not compile anymore. The error looks something like:
+
+```
+❯   CXX(target) Release/obj.target/accessors/cpp/accessors.o
+In file included from ../cpp/accessors.cpp:9:
+In file included from ../../nan.h:51:
+In file included from /Users/ofrobots/.node-gyp/0.12.18/include/node/node.h:61:
+/Users/ofrobots/.node-gyp/0.12.18/include/node/v8.h:5800:54: error: 'CreateHandle' is a protected member of 'v8::HandleScope'
+  return Handle<T>(reinterpret_cast<T*>(HandleScope::CreateHandle(
+                                        ~~~~~~~~~~~~~^~~~~~~~~~~~
+```
+
+This can be worked around by patching your local versions of v8.h corresponding to Node 0.12 to make
+`v8::Handle` a friend of `v8::HandleScope`. Since neither Node.js not V8 support this release line anymore
+this patch cannot be released by either project in an official release.
+
+For this reason, we do not test against Node.js 0.12 on OSX in this project's CI. If you need to support
+that configuration, you will need to either get an older compiler, or apply a source patch to the version
+of V8 headers as a workaround.

+## Governance & Contributing
+
+NAN is governed by the [Node.js Addon API Working Group](https://github.com/nodejs/CTC/blob/master/WORKING_GROUPS.md#addon-api)
+
+### Addon API Working Group (WG)
+
+The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
+
+Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other Node.js projects.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project [README.md](./README.md#collaborators).
+
+Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
+
+_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
+
+For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
+
+### Consensus Seeking Process
+
+The WG follows a [Consensus Seeking](https://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
+
+Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
+
+If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.

+## Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+This class internally handles the details of creating an [`AsyncResource`][AsyncResource], and running the callback in the
+correct async context. To be able to identify the async resources created by this class in async-hooks, provide a
+`resource_name` to the constructor. It is recommended that the module name be used as a prefix to the `resource_name` to avoid
+collisions in the names. For more details see [`AsyncResource`][AsyncResource] documentation.  The `resource_name` needs to stay valid for the lifetime of the worker instance.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+  explicit AsyncWorker(Callback *callback_, const char* resource_name = "nan:AsyncWorker");
+
+  virtual ~AsyncWorker();
+
+  virtual void WorkComplete();
+
+  void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(const v8::Local<v8::String> &key,
+                        const v8::Local<v8::Value> &value);
+
+  void SaveToPersistent(uint32_t index,
+                        const v8::Local<v8::Value> &value);

+### Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Previously the definition of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
+
+`Nan::AsyncProgressWorkerBase` &amp; `Nan::AsyncProgressWorker` is intended for best-effort delivery of nonessential progress messages, e.g. a progress bar.  The last event sent before the main thread is woken will be delivered.
+
+Definition:
+
+```c++
+template<class T>
+class AsyncProgressWorkerBase<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressWorkerBase(Callback *callback_, const char* resource_name = ...);
+
+  virtual ~AsyncProgressWorkerBase();
+
+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:
+    void Signal() const;
+    void Send(const T* data, size_t count) const;
+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;

+### Nan::AsyncProgressQueueWorker
+
+`Nan::AsyncProgressQueueWorker` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+`Nan::AsyncProgressQueueWorker` behaves exactly the same as `Nan::AsyncProgressWorker`, except all events are queued and delivered to the main thread.
+
+Definition:
+
+```c++

+class AsyncProgressQueueWorker<T> : public AsyncWorker {
+ public:
+  explicit AsyncProgressQueueWorker(Callback *callback_, const char* resource_name = "nan:AsyncProgressQueueWorker");

+  void WorkProgress();
+
+  class ExecutionProgress {
+   public:

+  };
+
+  virtual void Execute(const ExecutionProgress& progress) = 0;

+
+  virtual void Destroy();
+};
+```

+<a name="api_nan_async_queue_worker"></a>
+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.

+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+### Nan::MaybeLocal
+
+A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/node-8.16/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
+
+If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::MaybeLocal {
+ public:
+  MaybeLocal();
+
+  template<typename S> MaybeLocal(v8::Local<S> that);
+
+  bool IsEmpty() const;
+
+  template<typename S> bool ToLocal(v8::Local<S> *out);
+
+  // Will crash if the MaybeLocal<> is empty.
+  v8::Local<T> ToLocalChecked();
+
+  template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
+};

+### Nan::Maybe
+
+A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
+
+If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.

+## JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+### Nan::FunctionCallbackInfo
+
+`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class FunctionCallbackInfo {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Local<v8::Function> Callee(); // NOTE: Not available in NodeJS >= 10.0.0

+  int Length() const;
+  v8::Local<v8::Value> operator[](int i) const;
+  v8::Local<v8::Object> This() const;
+  v8::Isolate *GetIsolate() const;
+};
+```
+
+See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
+
+**Note:** `FunctionCallbackInfo::Callee` is removed in Node.js after `10.0.0` because it is was deprecated in V8. Consider using `info.Data()` to pass any information you need.

+### Nan::PropertyCallbackInfo
+
+`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
+ public:
+  ReturnValue<T> GetReturnValue() const;
+  v8::Isolate* GetIsolate() const;
+  v8::Local<v8::Value> Data() const;
+  v8::Local<v8::Object> This() const;

+
+See the [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
+
+<a name="api_nan_return_value"></a>
+### Nan::ReturnValue
+
+`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
+
+Example usage:
+
+```c++
+void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  info.GetReturnValue().Set(Nan::New<v8::Array>());
+}
+```
+
+Definition:
+
+```c++
+template<typename T> class ReturnValue {
+ public:
+  // Handle setters
+  template <typename S> void Set(const v8::Local<S> &handle);
+  template <typename S> void Set(const Nan::Global<S> &handle);
+

+
+<a name="api_nan_method"></a>
+### Method declaration
+
+JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
+
+```c++
+typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
+```
+
+Example:
+
+```c++
+void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
+
+**Example usage**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
+  static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
+}
+
+
+// .cc:
+void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+
+void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+  ...
+}
+```
+
+A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
+
+**Example usage with `NAN_METHOD(methodname)`**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+  ...
+
+  static NAN_METHOD(Bar);
+  static NAN_METHOD(Baz);
+}
+
+
+// .cc:
+NAN_METHOD(Foo::Bar) {
+  ...
+}
+
+NAN_METHOD(Foo::Baz) {
+  ...
+}
+```
+
+Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.

+```
+
+You do not need to declare a new `HandleScope` within a getter as one is implicitly created for you.
+
+A helper macro `NAN_GETTER(methodname)` exists, compatible with NAN v1 method declarations.

+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++
+Nan::New<T>(A0 arg0);
+Nan::New<T>(A0 arg0, A1 arg1);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
+```
+
+For creating `v8::FunctionTemplate` and `v8::Function` objects:
+
+_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
+
+```c++
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>());
+Nan::New<T>(Nan::FunctionCallback callback,
+            v8::Local<v8::Value> data = v8::Local<v8::Value>(),
+            A2 a2 = A2());
+```
+
+Native number types:
+
+```c++
+v8::Local<v8::Boolean> Nan::New<T>(bool value);
+v8::Local<v8::Int32> Nan::New<T>(int32_t value);
+v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
+v8::Local<v8::Number> Nan::New<T>(double value);
+```
+
+String types:
+
+```c++
+Nan::MaybeLocal<v8::String> Nan::New<T>(std::string const& value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value, int length);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value, int length);
+```
+
+Specialized types:
+
+```c++
+v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
+v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
+v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
+```
+
+Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/node-8.16/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

+### Nan::AsyncResource
+
+This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
+
+When calling back into JavaScript asynchronously, special care must be taken to ensure that the runtime can properly track
+async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
+and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
+`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
+such as domains and [async_hooks][] function correctly.
+
+Definition:
+
+```c++
+class AsyncResource {
+ public:
+  AsyncResource(v8::Local<v8::String> name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  AsyncResource(const char* name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  ~AsyncResource();
+
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::Function> func,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::String> symbol,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            const char* method,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+};
+```
+
+* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
+  API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
+  that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
+  `mysql:batch-db-query-resource`.
+* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
+  `init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
+* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
+  correct async execution context.
+* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
+
+For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
+[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
+
+<a name="api_nan_make_callback"></a>
+### Nan::MakeCallback()
+
+Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
+has deprecated these legacy APIs as they do not provide a mechanism to preserve
+async context.
+
+We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
+`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
+context – something that is essential for functionality like domains, async_hooks and async debugging.

+
+See the Node documentation on [Wrapping C++ Objects](https://nodejs.org/api/addons.html#addons_wrapping_c_objects) for more details.
+
+### This vs. Holder
+
+When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
+The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
+In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
+However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
+In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
+
+On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
+So either define your accessors on the instance template,
+or use `This()` after verifying that it is indeed a valid object.
+
+### Examples
+
+#### Basic
+
+```c++
+class MyObject : public Nan::ObjectWrap {
+ public:
+  static NAN_MODULE_INIT(Init) {
+    v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);

+    tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+    Nan::SetPrototypeMethod(tpl, "getHandle", GetHandle);
+    Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+    constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+    Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),
+      Nan::GetFunction(tpl).ToLocalChecked());
+  }
+
+ private:
+  explicit MyObject(double value = 0) : value_(value) {}
+  ~MyObject() {}
+
+  static NAN_METHOD(New) {
+    if (info.IsConstructCall()) {
+      double value = info[0]->IsUndefined() ? 0 : Nan::To<double>(info[0]).FromJust();
+      MyObject *obj = new MyObject(value);
+      obj->Wrap(info.This());
+      info.GetReturnValue().Set(info.This());
+    } else {

+      v8::Local<v8::Value> argv[argc] = {info[0]};
+      v8::Local<v8::Function> cons = Nan::New(constructor());

+    static Nan::Persistent<v8::Function> my_constructor;
+    return my_constructor;
+  }
+
+  double value_;
+};
+
+NODE_MODULE(objectwrapper, MyObject::Init)

+## Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+### Nan::Persistent
+
+A type of `PersistentBase` which allows copy and assignment. Copy, assignment and destructor behavior is controlled by the traits class `M`.

+
+<a name="api_nan_weak_callback_info"></a>
+### Nan::WeakCallbackInfo
+
+`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
+
+Definition:
+
+```c++
+template<typename T> class WeakCallbackInfo {
+ public:
+  typedef void (*Callback)(const WeakCallbackInfo<T>& data);
+
+  v8::Isolate *GetIsolate() const;
+
+  /**
+   * Get the parameter that was associated with the weak handle.
+   */
+  T *GetParameter() const;
+
+  /**
+   * Get pointer from internal field, index can be 0 or 1.
+   */
+  void *GetInternalField(int index) const;
+};
+```
+
+Example usage:
+
+```c++
+void weakCallback(const WeakCallbackInfo<int> &data) {
+  int *parameter = data.GetParameter();
+  delete parameter;
+}
+
+Persistent<v8::Object> obj;
+int *data = new int(0);
+obj.SetWeak(data, callback, WeakCallbackType::kParameter);
+```
+
+See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
+
+<a name="api_nan_weak_callback_type"></a>
+### Nan::WeakCallbackType
+
+Represents the type of a weak callback.
+A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
+A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
+Note that only `v8::Object`s and derivatives can have internal fields.
+
+Definition:
+
+```c++
+enum class WeakCallbackType { kParameter, kInternalFields };
+```

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/node-8.16/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+  Nan::HandleScope();
+  static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+  Nan::HandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+  Nan::EscapableHandleScope();
+  static int NumberOfHandles();
+  template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+  Nan::EscapableHandleScope scope;
+  v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+  return scope.Escape(obj);

+### Nan::Utf8String
+
+Converts an object to a UTF-8-encoded character array. If conversion to a string fails (e.g. due to an exception in the toString() method of the object) then the length() method returns 0 and the * operator returns NULL. The underlying memory used for this object is managed by the object.
+
+An implementation of [`v8::String::Utf8Value`](https://v8docs.nodesource.com/node-8.16/d4/d1b/classv8_1_1_string_1_1_utf8_value.html) that is consistent across all supported versions of V8.
+
+Definition:
+
+```c++
+class Nan::Utf8String {
+ public:
+  Nan::Utf8String(v8::Local<v8::Value> from);
+
+  int length() const;
+
+  char* operator*();
+  const char* operator*() const;
+};
+```
+
+<a name="api_nan_get_current_context"></a>
+### Nan::GetCurrentContext()
+
+A call to [`v8::Isolate::GetCurrent()->GetCurrentContext()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#a81c7a1ed7001ae2a65e89107f75fd053) that works across all supported versions of V8.

+### Nan::SetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#SetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#a7acadfe7965997e9c386a05f098fbe36).

+### Nan::GetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#GetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#aabd223436bc1100a787dadaa024c6257).

+
+<a name="api_nan_typedarray_contents"></a>
+### Nan::TypedArrayContents<T>
+
+A helper class for accessing the contents of an ArrayBufferView (aka a typedarray) from C++.  If the input array is not a valid typedarray, then the data pointer of TypedArrayContents will default to `NULL` and the length will be 0.  If the data pointer is not compatible with the alignment requirements of type, an assertion error will fail.
+
+Note that you must store a reference to the `array` object while you are accessing its contents.
+
+Definition:
+
+```c++
+template<typename T>
+class Nan::TypedArrayContents {
+ public:
+  TypedArrayContents(v8::Local<Value> array);
+
+  size_t length() const;
+
+  T* const operator*();
+  const T* const operator*() const;
+};

+1to2 naively converts source code files from NAN 1 to NAN 2. There will be erroneous conversions,
+false positives and missed opportunities. The input files are rewritten in place. Make sure that
+you have backups. You will have to manually review the changes afterwards and do some touchups.

+Thank you for reporting an issue!
+
+Remember, this issue tracker is for reporting issues ONLY with node-gyp.
+
+If you have an issue installing a specific module, please file an issue on
+that module's issue tracker (`npm issues modulename`). Open issue here only if
+you are sure this is an issue with node-gyp, not with the module you are
+trying to build.
+
+Fill out the form below. We probably won't investigate an issue that does not
+provide the basic information we require.
+
+-->
+
+Please look thru your error log for the string `gyp info using node-gyp@` and if the version number is less than the [current release of node-gyp](https://github.com/nodejs/node-gyp/releases) then __please upgrade__ using the instructions at https://github.com/nodejs/node-gyp/blob/master/docs/Updating-npm-bundled-node-gyp.md and try your command again.
+
+Requests for help with [`node-sass` are very common](https://github.com/nodejs/node-gyp/issues?q=label%3A%22Node+Sass+--%3E+Dart+Sass%22). Please be aware that this package is deprecated, you should seek alternatives and avoid opening new issues about it here.

+Paste your log here, between the backticks. It can be:
+  - npm --verbose output,
+  - or contents of npm-debug.log,
+  - or output of node-gyp rebuild --verbose.
+Include the command you were trying to run.
+
+This should look like this:
