Node.js packages
|
|
================
|
|
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 also provides support for multiple Node.js versions. The policy
|
|
is that a new package should be added to the collection for the latest stable LTS
|
|
release (which is currently 6.x), unless there is an explicit reason to support
|
|
a different release.
|
|
|
|
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 its expression in `default-v6.nix`:
|
|
|
|
```nix
|
|
dat = nodePackages.dat.override (oldAttrs: {
|
|
buildInputs = oldAttrs.buildInputs ++ [ nodePackages.node-gyp-build ];
|
|
});
|
|
```
|
|
|
|
To add a package from NPM to nixpkgs:
|
|
|
|
1. Modify `pkgs/development/node-packages/node-packages-v6.json` to add, update
|
|
or remove package entries. (Or `pkgs/development/node-packages/node-packages-v4.json`
|
|
for packages depending on Node.js 4.x)
|
|
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 a specific Node.js version (e.g. 4.x):
|
|
`nix-build -A nodePackages_4_x.<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.
