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.\n\nThis project also contains some helper utilities that make addon development a bit more pleasant.\n\n * **[News & Updates](#news)**\n * **[Usage](#usage)**\n * **[Example](#example)**\n * **[API](#api)**\n\n<a name="news"></a>\n## News & Updates\n\n### Dec-2013: NanCString and NanRawString\n\nTwo new functions have been introduced to replace the functionality that\'s been provided by `NanFromV8String` until now. NanCString has sensible defaults so it\'s super easy to fetch a null-terminated c-style string out of a `v8::String`. `NanFromV8String` is still around and has defaults that allow you to pass a single handle to fetch a `char*` while `NanRawString` requires a little more attention to arguments.\n\n### Nov-2013: Node 0.11.9+ breaking V8 change\n\nThe version of V8 that\'s shipping with Node 0.11.9+ has changed the signature for new `Local`s to: `v8::Local<T>::New(isolate, value)`, i.e. introducing the `isolate` argument and therefore breaking all new `Local` declarations for previous versions. NAN 0.6+ now includes a `NanNewLocal<T>(value)` that can be used in place to work around this incompatibility and maintain compatibility with 0.8->0.11.9+ (minus a few early 0.11 releases).\n\nFor example, if you wanted to return a `null` on a callback you will have to change the argument from `v8::Local<v8::Value>::New(v8::Null())` to `NanNewLocal<v8::Value>(v8::Null())`.\n\n### Nov-2013: Change to binding.gyp `"include_dirs"` for NAN\n\nInclusion of NAN in a project\'s binding.gyp is now greatly simplified. You can now just use `"<!(node -e \\"require(\'nan\')\\")"` in your `"include_dirs"`, see example below (note Windows needs the quoting around `require` to be just right: `"require(\'nan\')"` with appropriate `\\` escaping).\n\n<a name="usage"></a>\n## Usage\n\nSimply add **NAN** as a dependency in the *package.json* of your Node addon:\n\n``` bash\n$ npm install --save nan\n```\n\nPull in the path to **NAN** in your *binding.gyp* so that you can use `#include "nan.h"` in your *.cpp* files:\n\n``` python\n"include_dirs" : [\n "<!(node -e \\"require(\'nan\')\\")"\n]\n```\n\nThis works like a `-I<path-to-NAN>` when compiling your addon.\n\n<a name="example"></a>\n## Example\n\nSee **[LevelDOWN](https://github.com/rvagg/node-leveldown/pull/48)** for a full example of **NAN** in use.\n\nFor a simpler example, see the **[async pi estimation example](https://github.com/rvagg/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.\n\nCompare to the current 0.10 version of this example, found in the [node-addon-examples](https://github.com/rvagg/node-addon-examples/tree/master/9_async_work) repository and also a 0.11 version of the same found [here](https://github.com/kkoopa/node-addon-examples/tree/5c01f58fc993377a567812597e54a83af69686d7/9_async_work).\n\nNote that there is no embedded version sniffing going on here and also the async work is made much simpler, see below for details on the `NanAsyncWorker` class.\n\n```c++\n// addon.cc\n#include <node.h>\n#include "nan.h"\n// ...\n\nusing namespace v8;\n\nvoid InitAll(Handle<Object> exports) {\n exports->Set(NanSymbol("calculateSync"),\n FunctionTemplate::New(CalculateSync)->GetFunction());\n\n exports->Set(NanSymbol("calculateAsync"),\n FunctionTemplate::New(CalculateAsync)->GetFunction());\n}\n\nNODE_MODULE(addon, InitAll)\n```\n\n```c++\n// sync.h\n#include <node.h>\n#include "nan.h"\n\nNAN_METHOD(CalculateSync);\n```\n\n```c++\n// sync.cc\n#include <node.h>\n#include "nan.h"\n#include "sync.h"\n// ...\n\nusing namespace v8;\n\n// Simple synchronous access to the `Estimate()` function\nNAN_METHOD(CalculateSync) {\n NanScope();\n\n // expect a number as the first argument\n int points = args[0]->Uint32Value();\n double est = Estimate(points);\n\n NanReturnValue(Number::New(est));\n}\n```\n\n```c++\n// async.cc\n#include <node.h>\n#include "nan.h"\n#include "async.h"\n\n// ...\n\nusing namespace v8;\n\nclass PiWorker : public NanAsyncWorker {\n public:\n PiWorker(NanCallback *callback, int points)\n : NanAsyncWorker(callback), points(points) {}\n ~PiWorker() {}\n\n // Executed inside the worker-thread.\n // It is not safe to access V8, or V8 data structures\n // here, so everything we need for input and output\n // should go on `this`.\n void Execute () {\n estimate = Estimate(points);\n }\n\n // Executed when the async work is complete\n // this function will be run inside the main event loop\n // so it is safe to use V8 again\n void HandleOKCallback () {\n NanScope();\n\n Local<Value> argv[] = {\n Local<Value>::New(Null())\n , Number::New(estimate)\n };\n\n callback->Call(2, argv);\n };\n\n private:\n int points;\n double estimate;\n};\n\n// Asynchronous access to the `Estimate()` function\nNAN_METHOD(CalculateAsync) {\n NanScope();\n\n int points = args[0]->Uint32Value();\n NanCallback *callback = new NanCallback(args[1].As<Function>());\n\n NanAsyncQueueWorker(new PiWorker(callback, points));\n NanReturnUndefined();\n}\n```\n\n<a name="api"></a>\n## API\n\n * <a

methods:\n\n```c++\n// .h:\nclass Foo : public node::ObjectWrap {\n ...\n\n static NAN_METHOD(Bar);\n static NAN_METHOD(Baz);\n}\n\n\n// .cc:\nNAN_METHOD(Foo::Bar) {\n ...\n}\n\nNAN_METHOD(Foo::Baz) {\n ...\n}\n```\n\nThe reason for this macro is because of the method signature change in 0.11:\n\n```c++\n// 0.10 and below:\nHandle<Value> name(const Arguments& args)\n\n// 0.11 and above\nvoid name(const FunctionCallbackInfo<Value>& args)\n```\n\nThe introduction of `FunctionCallbackInfo` brings additional complications:\n\n<a name="api_nan_getter"></a>\n### NAN_GETTER(methodname)\n\nUse `NAN_GETTER` to declare your V8 accessible getters. You get a `Local<String>` `property` and an appropriately typed `args` object that can act like the `args` argument to a `NAN_METHOD` call.\n\nYou can use `NanReturnNull()`, `NanReturnEmptyString()`, `NanReturnUndefined()` and `NanReturnValue()` in a `NAN_GETTER`.\n\n<a name="api_nan_setter"></a>\n### NAN_SETTER(methodname)\n\nUse `NAN_SETTER` to declare your V8 accessible setters.

There is an object argument accessible through `NAN_WEAK_CALLBACK_OBJECT`. The `type` argument gives the type of the `data` argument, accessible through `NAN_WEAK_CALLBACK_DATA(type)`.\n\n```c++\nstatic NAN_WEAK_CALLBACK(BufferReference*, WeakCheck) {\n if (NAN_WEAK_CALLBACK_DATA(BufferReference*)->noLongerNeeded_) {\n delete NAN_WEAK_CALLBACK_DATA(BufferReference*);\n } else {\n // Still in use, revive, prevent GC\n NanMakeWeak(NAN_WEAK_CALLBACK_OBJECT, NAN_WEAK_CALLBACK_DATA(BufferReference*), &WeakCheck);\n }\n}\n```\n\n<a name="api_nan_deprecated"></a>\n### NAN_DEPRECATED(declarator)\nDeclares a function as deprecated.

If the pointer is `NULL`, the function returns the optional default value, which defaults to `0`. Otherwise, the function returns the value the pointer points to.\n\n```c++\nchar *plugh(uint32_t *optional) {\n char res[] = "xyzzy";\n uint32_t param = NanGetPointerSafe<uint32_t>(optional, 0x1337);\n switch (param) {\n ...\n }\n NanSetPointerSafe<uint32_t>(optional, 0xDEADBEEF);\n} \n```\n\n<a name="api_nan_set_pointer_safe"></a>\n### bool NanSetPointerSafe(Type *, Type)\n\nA helper for setting optional argument pointers. If the pointer is `NULL`, the function simply return `false`. Otherwise, the value is assigned to the variable the pointer points to.\n\n```c++\nconst char *plugh(size_t *outputsize) {\n char res[] = "xyzzy";\n if !(NanSetPointerSafe<size_t>(outputsize, strlen(res) + 1)) {\n ...\n }\n\n ...\n}\n```\n\n<a name="api_nan_raw_string"></a>\n### void* NanRawString(Handle<Value>, enum Nan::Encoding, size_t *, void *, size_t, int)\n\nWhen you want to convert a V8 `String` to a `char*` buffer, use `NanRawString`. You have to supply an encoding as well as a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows setting `String::WriteOptions`.\nJust remember that you\'ll end up with an object that you\'ll need to `delete[]` at some point unless you supply your own buffer:\n\n```c++\nsize_t count;\nvoid* decoded = NanRawString(args[1], Nan::BASE64, &count, NULL, 0, String::HINT_MANY_WRITES_EXPECTED);\nchar param_copy[count];\nmemcpy(param_copy, decoded, count);\ndelete[] decoded;\n```\n\n<a name="api_nan_c_string"></a>\n### char* NanCString(Handle<Value>, size_t *[, char *, size_t, int])\n\nWhen you want to convert a V8 `String` to a null-terminated C `char*` use `NanCString`. The resulting `char*` will be UTF-8-encoded, and you need to supply a pointer to a variable that will be assigned the number of bytes in the returned string. It is also possible to supply a buffer and its length to the function in order not to have a new buffer allocated. The final argument allows optionally setting `String::WriteOptions`, which default to `v8::String::NO_OPTIONS`.\nJust remember that you\'ll end up with an object that you\'ll need to `delete[]` at some point unless you supply your own buffer:\n\n```c++\nsize_t count;\nchar* name = NanCString(args[0], &count);\n```\n\n<a name="api_nan_from_v8_string"></a>\n### char* NanFromV8String(Handle<Value>[, enum Nan::Encoding, size_t *, char *, size_t, int])\n\nA convenience function that uses `NanRawString()` to convert a V8 `String` to a `char*`. Defaults to UTF8 encoding and no null-termination.\n\n```c++\nsize_t count;\nchar* name = NanFromV8String(args[0]);\n```\n\n<a name="api_nan_boolean_option_value"></a>\n### bool NanBooleanOptionValue(Handle<Value>, Handle<String>[, bool])\n\nWhen you have an "options" object that you need to fetch properties from, boolean options can be fetched with this pair. They check first if the object exists (`IsEmpty`), then if the object has the given property (`Has`) then they get and convert/coerce the property to a `bool`.\n\nThe optional last parameter is the *default* value, which is `false` if left off:\n\n```c++\n// `foo` is false unless the user supplies a truthy value for it\nbool foo = NanBooleanOptionValue(optionsObj, NanSymbol("foo"));\n// `bar` is true unless the user supplies a falsy value for it\nbool bar = NanBooleanOptionValueDefTrue(optionsObj, NanSymbol("bar"), true);\n```\n\n<a name="api_nan_uint32_option_value"></a>\n### uint32_t NanUInt32OptionValue(Handle<Value>, Handle<String>, uint32_t)\n\nSimilar to `NanBooleanOptionValue`, use `NanUInt32OptionValue` to fetch an integer option from your options object. Can be any kind of JavaScript `Number` and it will be coerced to an unsigned 32-bit integer.\n\nRequires all 3 arguments as a default is not optional:\n\n```c++\nuint32_t count = NanUInt32OptionValue(optionsObj, NanSymbol("count"), 1024);\n```\n\n<a name="api_nan_error"></a>\n### NanError(message), NanTypeError(message), NanRangeError(message)\n\nFor making `Error`, `TypeError` and `RangeError` objects.\n\n```c++\nLocal<Value> res = NanError("you must supply a callback argument");\n```\n\n<a name="api_nan_throw_error"></a>\n### NanThrowError(message), NanThrowTypeError(message), NanThrowRangeError(message), NanThrowError(Local<Value>), NanThrowError(Local<Value>, int)\n\nFor throwing `Error`, `TypeError` and `RangeError` objects. You should `return` this call:\n\n```c++\nreturn NanThrowError("you must supply a callback argument");\n```\n\nCan also handle any custom object you may want to throw. If used with the error code argument, it will add the supplied error code to the error object as a property called `code`.\n\n<a name="api_nan_new_buffer_handle"></a>\n### Local<Object> NanNewBufferHandle(char *, uint32_t), Local<Object> NanNewBufferHandle(uint32_t)\n\nThe `Buffer` API has changed a little in Node 0.11, this helper provides consistent access to `Buffer` creation:\n\n```c++\nNanNewBufferHandle((char*)value.data(), value.size());\n```\n\nCan also be used to initialize a `Buffer` with just a `size` argument.\n\nCan also be supplied with a `NAN_WEAK_CALLBACK` and a hint for the garbage collector, when dealing with weak references.\n\n<a name="api_nan_buffer_use"></a>\n### Local<Object> NanBufferUse(char*, uint32_t)\n\n`Buffer::New(char*, uint32_t)` prior to 0.11 would make a copy of the data.\nWhile it was possible to get around this, it required a shim by passing a\ncallback. So the new API `Buffer::Use(char*, uint32_t)` was introduced to remove\nneeding to use this shim.\n\n`NanBufferUse` uses the `char*` passed as the backing data, and will free the\nmemory automatically when the weak callback is called. Keep this in mind, as\ncareless use can lead to "double free or corruption" and other cryptic failures.\n\n<a name="api_nan_has_instance"></a>\n### bool NanHasInstance(Persistent<FunctionTemplate>&, Handle<Value>)\n\nCan be used to check the type of an object to determine it is of a particular class you have already defined and have a `Persistent<FunctionTemplate>` handle for.\n\n<a name="api_nan_persistent_to_local"></a>\n### Local<Type> NanPersistentToLocal(Persistent<Type>&)\n\nAside from `FunctionCallbackInfo`, the biggest and most painful change to V8 in Node 0.11 is the many restrictions now placed on `Persistent` handles. They are difficult to assign and difficult to fetch the original value out of.\n\nUse `NanPersistentToLocal` to convert a `Persistent` handle back to a `Local` handle.\n\n```c++\nLocal<Object> handle = NanPersistentToLocal(persistentHandle);\n```\n\n<a href="#api_nan_new_context_handle">\n### Local<Context> NanNewContextHandle([ExtensionConfiguration*, Handle<ObjectTemplate>, Handle<Value>])\nCreates a new `Local<Context>` handle.\n\n```c++\nLocal<FunctionTemplate> ftmpl = FunctionTemplate::New();\nLocal<ObjectTemplate> otmpl = ftmpl->InstanceTemplate();\nLocal<Context> ctx = NanNewContextHandle(NULL, otmpl);\n```\n\n<a name="api_nan_dispose_persistent"></a>\n### void NanDisposePersistent(Persistent<T> &)\n\nUse `NanDisposePersistent` to dispose a `Persistent` handle.\n\n```c++\nNanDisposePersistent(persistentHandle);\n```\n\n<a name="api_nan_assign_persistent"></a>\n### NanAssignPersistent(type, handle, object)\n\nUse `NanAssignPersistent` to assign a non-`Persistent` handle to a `Persistent` one. You can no longer just declare a `Persistent` handle and assign directly to it later, you have to `Reset` it in Node 0.11, so this makes it easier.\n\nIn general it is now better to place anything you want to protect from V8\'s garbage collector as properties of a generic `Object` and then assign that to a `Persistent`. This works in older versions of Node also if you use `NanAssignPersistent`:\n\n```c++\nPersistent<Object> persistentHandle;\n\n...\n\nLocal<Object> obj = Object::New();\nobj->Set(NanSymbol("key"), keyHandle); // where keyHandle might be a Local<String>\nNanAssignPersistent(Object, persistentHandle, obj)\n```\n\n<a name="api_nan_init_persistent"></a>\n### NanInitPersistent(type, name, object)\n\nUser `NanInitPersistent` to declare and initialize a new `Persistent` with the supplied object. The assignment operator for `Persistent` is no longer public in Node 0.11, so this macro makes it easier to declare and initializing a new `Persistent`. See <a href="#api_nan_assign_persistent"><b><code>NanAssignPersistent</code></b></a> for more information.\n\n```c++\nLocal<Object> obj = Object::New();\nobj->Set(NanSymbol("key"), keyHandle); // where keyHandle might be a Local<String>\nNanInitPersistent(Object, persistentHandle, obj);\n```\n\n<a name="api_nan_callback"></a>\n### NanCallback\n\nBecause of the difficulties imposed by the changes to `Persistent` handles in V8 in Node 0.11, creating `Persistent` versions of your `Handle<Function>` is annoyingly tricky. `NanCallback` makes it easier by taking your handle, making it persistent until the `NanCallback` is deleted and even providing a handy `Call()` method to fetch and execute the callback `Function`.\n\n```c++\nLocal<Function> callbackHandle = args[0].As<Function>();\nNanCallback *callback = new NanCallback(callbackHandle);\n// pass `callback` around and it\'s safe from GC until you:\ndelete callback;\n```\n\nYou can execute the callback like so:\n\n```c++\n// no arguments:\ncallback->Call(0, NULL);\n\n// an error argument:\nHandle<Value> argv[] = {\n Exception::Error(String::New("fail!"))\n};\ncallback->Call(1, argv);\n\n// a success argument:\nHandle<Value> argv[] = {\n Null(),\n String::New("w00t!")\n};\ncallback->Call(2, argv);\n```\n\n`NanCallback` also has a `Local<Function> GetCallback()` method that you can use\nto fetch a local handle to the underlying callback function, as well as a\n`void SetFunction(Handle<Function>)` for setting the callback on the\n`NanCallback`. Additionally a generic constructor is available for using\n`NanCallback` without performing heap allocations.\n\n<a name="api_nan_async_worker"></a>\n### NanAsyncWorker\n\n`NanAsyncWorker` is an abstract class that you can subclass to have much of the annoying async queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the async work is in progress.\n\nSee a rough outline of the implementation:\n\n```c++\nclass NanAsyncWorker {\npublic:\n NanAsyncWorker (NanCallback *callback);\n\n // Clean up persistent handles and delete the *callback\n virtual ~NanAsyncWorker ();\n\n // Check the `char *errmsg` property and call HandleOKCallback()\n // or HandleErrorCallback depending on whether it has been set or not\n virtual void WorkComplete ();\n\n // You must implement this to do some async work. If there is an\n // error then allocate `errmsg` to to a message and the callback will\n // be passed that string in an Error object\n virtual void Execute ();\n\n // Save a V8 object in a Persistent handle to protect it from GC\n void SavePersistent(const char *key, Local<Object> &obj);\n\n // Fetch a stored V8 object (don\'t call from within `Execute()`)\n Local<Object> GetFromPersistent(const char *key);\n\nprotected:\n // Set this if there is an error, otherwise it\'s NULL\n const char *errmsg;\n\n // Default implementation calls the callback function with no arguments.\n // Override this to return meaningful data\n virtual void HandleOKCallback ();\n\n // Default implementation calls the callback function with an Error object\n // wrapping the `errmsg` string\n virtual void HandleErrorCallback ();\n};\n```\n\n<a name="api_nan_async_queue_worker"></a>\n### NanAsyncQueueWorker(NanAsyncWorker *)\n\n`NanAsyncQueueWorker` will run a `NanAsyncWorker` 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 `NanAsyncWorker`.\n\n### Contributors\n\nNAN is only possible due to the excellent work of the following contributors:\n\n<table><tbody>\n<tr><th align="left">Rod Vagg</th><td><a href="https://github.com/rvagg">GitHub/rvagg</a></td><td><a href="http://twitter.com/rvagg">Twitter/@rvagg</a></td></tr>\n<tr><th align="left">Benjamin Byholm</th><td><a href="https://github.com/kkoopa/">GitHub/kkoopa</a></td></tr>\n<tr><th align="left">Trevor Norris</th><td><a href="https://github.com/trevnorris">GitHub/trevnorris</a></td><td><a href="http://twitter.com/trevnorris">Twitter/@trevnorris</a></td></tr>\n<tr><th align="left">Nathan Rajlich</th><td><a href="https://github.com/TooTallNate">GitHub/TooTallNate</a></td><td><a href="http://twitter.com/TooTallNate">Twitter/@TooTallNate</a></td></tr>\n<tr><th align="left">Brett Lawson</th><td><a href="https://github.com/brett19">GitHub/brett19</a></td><td><a href="http://twitter.com/brett19x">Twitter/@brett19x</a></td></tr>\n<tr><th align="left">Ben Noordhuis</th><td><a href="https://github.com/bnoordhuis">GitHub/bnoordhuis</a></td><td><a href="http://twitter.com/bnoordhuis">Twitter/@bnoordhuis</a></td></tr>\n</tbody></table>\n\nLicence & copyright\n-----------------------\n\nCopyright (c) 2013 NAN contributors (listed above).\n\nNative Abstractions for Node.js is licensed under an MIT +no-false-attribs license.
