| Node.js
 | |
| =======
 | |
| The `pkgs/development/node-packages` folder contains a generated collection of
 | |
| [NPM packages](https://npmjs.com/) that can be installed with the Nix package
 | |
| manager.
 | |
| 
 | |
| As a rule of thumb, the package set should only provide *end user* software
 | |
| packages, such as command-line utilities. Libraries should only be added to the
 | |
| package set if there is a non-NPM package that requires it.
 | |
| 
 | |
| When it is desired to use NPM libraries in a development project, use the
 | |
| `node2nix` generator directly on the `package.json` configuration file of the
 | |
| project.
 | |
| 
 | |
| The package set provides support for the official stable Node.js versions.
 | |
| The latest stable LTS release in `nodePackages`, as well as the latest stable
 | |
| Current release in `nodePackages_latest`.
 | |
| 
 | |
| If your package uses native addons, you need to examine what kind of native
 | |
| build system it uses. Here are some examples:
 | |
| 
 | |
| * `node-gyp`
 | |
| * `node-gyp-builder`
 | |
| * `node-pre-gyp`
 | |
| 
 | |
| After you have identified the correct system, you need to override your package
 | |
| expression while adding in build system as a build input. For example, `dat`
 | |
| requires `node-gyp-build`, so [we override](https://github.com/NixOS/nixpkgs/blob/32f5e5da4a1b3f0595527f5195ac3a91451e9b56/pkgs/development/node-packages/default.nix#L37-L40) its expression in [`default.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/node-packages/default.nix):
 | |
| 
 | |
| ```nix
 | |
|     dat = super.dat.override {
 | |
|       buildInputs = [ self.node-gyp-build pkgs.libtool pkgs.autoconf pkgs.automake ];
 | |
|       meta.broken = since "12";
 | |
|     };
 | |
| ```
 | |
| 
 | |
| To add a package from NPM to nixpkgs:
 | |
| 
 | |
|  1. Modify `pkgs/development/node-packages/node-packages.json` to add, update
 | |
|     or remove package entries to have it included in `nodePackages` and
 | |
|     `nodePackages_latest`.
 | |
|  2. Run the script: `(cd pkgs/development/node-packages && ./generate.sh)`.
 | |
|  3. Build your new package to test your changes:
 | |
|     `cd /path/to/nixpkgs && nix-build -A nodePackages.<new-or-updated-package>`.
 | |
|     To build against the latest stable Current Node.js version (e.g. 14.x):
 | |
|     `nix-build -A nodePackages_latest.<new-or-updated-package>`
 | |
|  4. Add and commit all modified and generated files.
 | |
| 
 | |
| For more information about the generation process, consult the
 | |
| [README.md](https://github.com/svanderburg/node2nix) file of the `node2nix`
 | |
| tool.
