It contains a vendored copy of the [gyp-next](https://github.com/nodejs/gyp-next) project that was previously used by the Chromium team, extended to support the development of Node.js native addons. Note that `node-gyp` is _not_ used to build Node.js itself. Multiple target versions of Node.js are supported (i.e. `0.8`, ..., `4`, `5`, `6`, etc.), regardless of what version of Node.js is actually installed on your system (`node-gyp` downloads the necessary development files or headers for the target version). ## Features * The same build commands work on any of the supported platforms * Supports the targeting of different versions of Node.js ## Installation You can install `node-gyp` using `npm`: ``` bash npm install -g node-gyp ``` Depending on your operating system, you will need to install: ### On Unix * Python v3.6, v3.7, v3.8, or v3.9 * `make` * A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org) ### On macOS **ATTENTION**: If your Mac has been _upgraded_ to macOS Catalina (10.15), please read [macOS_Catalina.md](macOS_Catalina.md). * Python v3.6, v3.7, v3.8, or v3.9 * [Xcode](https://developer.apple.com/xcode/download/) * You also need to install the `XCode Command Line Tools` by running `xcode-select --install`. Alternatively, if you already have the full Xcode installed, you can find them under the menu `Xcode -> Open Developer Tool -> More Developer Tools...`. This step will install `clang`, `clang++`, and `make`. ### On Windows Install the current version of Python from the [Microsoft Store package](https://docs.python.org/3/using/windows.html#the-microsoft-store-package). Install tools and configuration manually: * Install Visual C++ Build Environment: [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools) (using "Visual C++ build tools" workload) or [Visual Studio Community](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community) (using the "Desktop development with C++" workload) * Launch cmd, `npm config set msvs_version 2017` If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips. To target native ARM64 Node.js on Windows 10 on ARM, add the components "Visual C++ compilers and libraries for ARM64" and "Visual C++ ATL for ARM64". ### Configuring Python Dependency `node-gyp` requires that you have installed a compatible version of Python, one of: v3.6, v3.7, v3.8, or v3.9. If you have multiple Python versions installed, you can identify which Python version `node-gyp` should use in one of the following ways: 1. by setting the `--python` command-line option, e.g.: ``` bash node-gyp --python /path/to/executable/python ``` 2. If `node-gyp` is called by way of `npm`, *and* you have multiple versions of Python installed, then you can set `npm`'s 'python' config key to the appropriate value: ``` bash npm config set python /path/to/executable/python ``` 3. If the `PYTHON` environment variable is set to the path of a Python executable, then that version will be used, if it is a compatible version. 4. If the `NODE_GYP_FORCE_PYTHON` environment variable is set to the path of a Python executable, it will be used instead of any of the other configured or builtin Python search paths. If it's not a compatible version, no further searching will be done. ### Build for Third Party Node.js Runtimes When building modules for thid party Node.js runtimes like Electron, which have different build configurations from the official Node.js distribution, you should use `--dist-url` or `--nodedir` flags to specify the headers of the runtime to build for. Also when `--dist-url` or `--nodedir` flags are passed, node-gyp will use the `config.gypi` shipped in the headers distribution to generate build configurations, which is different from the default mode that would use the `process.config` object of the running Node.js instance. Some old versions of Electron shipped malformed `config.gypi` in their headers distributions, and you might need to pass `--force-process-config` to node-gyp to work around configuration errors. ## How to Use To compile your native addon, first go to its root directory: ``` bash cd my_node_addon ``` The next step is to generate the appropriate project build files for the current platform. Use `configure` for that: ``` bash node-gyp configure ``` Auto-detection fails for Visual C++ Build Tools 2015, so `--msvs_version=2015` needs to be added (not needed when run by npm as configured above): ``` bash node-gyp configure --msvs_version=2015 ``` __Note__: The `configure` step looks for a `binding.gyp` file in the current directory to process. See below for instructions on creating a `binding.gyp` file. Now you will have either a `Makefile` (on Unix platforms) or a `vcxproj` file (on Windows) in the `build/` directory. Next, invoke the `build` command: ``` bash node-gyp build ``` Now you have your compiled `.node` bindings file! The compiled bindings end up in `build/Debug/` or `build/Release/`, depending on the build mode. At this point, you can require the `.node` file with Node.js and run your tests! __Note:__ To create a _Debug_ build of the bindings file, pass the `--debug` (or `-d`) switch when running either the `configure`, `build` or `rebuild` commands. ## The `binding.gyp` file A `binding.gyp` file describes the configuration to build your module, in a JSON-like format. This file gets placed in the root of your package, alongside `package.json`. A barebones `gyp` file appropriate for building a Node.js addon could look like: ```python { "targets": [ { "target_name": "binding", "sources": [ "src/binding.cc" ] } ] } ``` ## Further reading The **[docs](./docs/)** directory contains additional documentation on specific node-gyp topics that may be useful if you are experiencing problems installing or building addons using node-gyp. Some additional resources for Node.js native addons and writing `gyp` configuration files: * ["Going Native" a nodeschool.io tutorial](http://nodeschool.io/#goingnative) * ["Hello World" node addon example](https://github.com/nodejs/node/tree/master/test/addons/hello-world) * [gyp user documentation](https://gyp.gsrc.io/docs/UserDocumentation.md) * [gyp input format reference](https://gyp.gsrc.io/docs/InputFormatReference.md) * [*"binding.gyp" files out in the wild* wiki page](./docs/binding.gyp-files-in-the-wild.md) ## Commands `node-gyp` responds to the following commands: | **Command** | **Description** |:--------------|:--------------------------------------------------------------- | `help` | Shows the help dialog | `build` | Invokes `make`/`msbuild.exe` and builds the native addon | `clean` | Removes the `build` directory if it exists | `configure` | Generates project build files for the current platform | `rebuild` | Runs `clean`, `configure` and `build` all in a row | `install` | Installs Node.js header files for the given version | `list` | Lists the currently installed Node.js header versions | `remove` | Removes the Node.js header files for the given version ## Command Options `node-gyp` accepts the following command options: | **Command** | **Description** |:----------------------------------|:------------------------------------------ | `-j n`, `--jobs n` | Run `make` in parallel. The value `max` will use all available CPU cores | `--target=v6.2.1` | Node.js version to build for (default is `process.version`) | `--silly`, `--loglevel=silly` | Log all progress to console | `--verbose`, `--loglevel=verbose` | Log most progress to console | `--silent`, `--loglevel=silent` | Don't log anything to console | `debug`, `--debug` | Make Debug build (default is `Release`) | `--release`, `--no-debug` | Make Release build | `-C $dir`, `--directory=$dir` | Run command in different directory | `--make=$make` | Override `make` command (e.g. `gmake`) | `--thin=yes` | Enable thin static libraries | `--arch=$arch` | Set target architecture (e.g. ia32) | `--tarball=$path` | Get headers from a local tarball | `--devdir=$path` | SDK download directory (default is OS cache directory) | `--ensure` | Don't reinstall headers if already present | `--dist-url=$url` | Download header tarball from custom URL | `--proxy=$url` | Set HTTP(S) proxy for downloading header tarball | `--noproxy=$urls` | Set urls to ignore proxies when downloading header tarball | `--cafile=$cafile` | Override default CA chain (to download tarball) | `--nodedir=$path` | Set the path to the node source code | `--python=$path` | Set path to the Python binary | `--msvs_version=$version` | Set Visual Studio version (Windows only) | `--solution=$solution` | Set Visual Studio Solution version (Windows only) | `--force-process-config` | Force using runtime's `process.config` object to generate `config.gypi` file ## Configuration ### Environment variables Use the form `npm_config_OPTION_NAME` for any of the command options listed above (dashes in option names should be replaced by underscores). For example, to set `devdir` equal to `/tmp/.gyp`, you would: Run this on Unix: ```bash export npm_config_devdir=/tmp/.gyp ``` Or this on Windows: ```console set npm_config_devdir=c:\temp\.gyp ``` ### `npm` configuration Use the form `OPTION_NAME` for any of the command options listed above. For example, to set `devdir` equal to `/tmp/.gyp`, you would run: ```bash npm config set [--global] devdir /tmp/.gyp ``` **Note:** Configuration set via `npm` will only be used when `node-gyp` is run via `npm`, not when `node-gyp` is run directly. ## License `node-gyp` is available under the MIT license. See the [LICENSE file](LICENSE) for details.
