> Build tool and bindings loader for [`node-gyp`][node-gyp] that supports prebuilds.
|
|
|
|
```
|
|
npm install node-gyp-build
|
|
```
|
|
|
|
[](https://github.com/prebuild/node-gyp-build/actions/workflows/test.yml)
|
|
|
|
Use together with [`prebuildify`][prebuildify] to easily support prebuilds for your native modules.
|
|
|
|
## Usage
|
|
|
|
> **Note.** Prebuild names have changed in [`prebuildify@3`][prebuildify] and `node-gyp-build@4`. Please see the documentation below.
|
|
|
|
`node-gyp-build` works similar to [`node-gyp build`][node-gyp] except that it will check if a build or prebuild is present before rebuilding your project.
|
|
|
|
It's main intended use is as an npm install script and bindings loader for native modules that bundle prebuilds using [`prebuildify`][prebuildify].
|
|
|
|
First add `node-gyp-build` as an install script to your native project
|
|
|
|
``` js
|
|
{
|
|
...
|
|
"scripts": {
|
|
"install": "node-gyp-build"
|
|
}
|
|
}
|
|
```
|
|
|
|
Then in your `index.js`, instead of using the [`bindings`](https://www.npmjs.com/package/bindings) module use `node-gyp-build` to load your binding.
|
|
|
|
``` js
|
|
var binding = require('node-gyp-build')(__dirname)
|
|
```
|
|
|
|
If you do these two things and bundle prebuilds with [`prebuildify`][prebuildify] your native module will work for most platforms
|
|
without having to compile on install time AND will work in both node and electron without the need to recompile between usage.
|
|
|
|
Users can override `node-gyp-build` and force compiling by doing `npm install --build-from-source`.
|
|
|
|
Prebuilds will be attempted loaded from `MODULE_PATH/prebuilds/...` and then next `EXEC_PATH/prebuilds/...` (the latter allowing use with `zeit/pkg`)
|
|
|
|
## Supported prebuild names
|
|
|
|
If so desired you can bundle more specific flavors, for example `musl` builds to support Alpine, or targeting a numbered ARM architecture version.
|
|
|
|
These prebuilds can be bundled in addition to generic prebuilds; `node-gyp-build` will try to find the most specific flavor first. Prebuild filenames are composed of _tags_. The runtime tag takes precedence, as does an `abi` tag over `napi`. For more details on tags, please see [`prebuildify`][prebuildify].
|
|
|
|
Values for the `libc` and `armv` tags are auto-detected but can be overridden through the `LIBC` and `ARM_VERSION` environment variables, respectively.
