@yarnpkg/plugin-prebuilds

For Yarn v2.

To install, import from the repository.

yarn plugin import https://raw.githubusercontent.com/electricui/yarn-prebuilds/master/bundles/%40yarnpkg/plugin-prebuilds.js

The bindings package creates a runtime error in order to reflect its caller's filepath, which is used to search the filesystem for the correct .node native binding.

This plugin intercepts packages with dependencies to bindings and automatically grabs the prebuild for that version. If electron is in your dependencies list, the runtime is set to electron.

It rewrites the bindings dependency for each package to statically refer to the .node binding, removing all runtime searching.

Node-abi is bundled into this plugin, so it will need to be updated each time Electron releases a new ABI version.

Once the dependency is referred to statically, a Webpack plugin or Rollup plugin can be used to consume and load the .node file like any other asset.

For example, we use webpack-dev-server and have a loader that provides an absolute path during development. During bundling, we copy the .node file to a relative path and package it with the bundle.

All Configuration

Configuration can be set in your .yarnrc.yml file.

prebuildScopes:
  '@serialport':
    prebuildTagPrefix: '@serialport/bindings@'
    prebuildHostMirrorUrl: 'https://custom-prebuild-mirror.com/prebuilds'
    prebuildHostMirrorTemplate: '{mirror_url}/{scopeWithAtAndSlash}{name}-v{version}-{runtime}-v{abi}-{platform}{libc}-{arch}.tar.gz'
prebuildHostMirrorUrl: 'https://other-custom-prebuild-mirror.com/prebuilds'
prebuildHostMirrorTemplate: '{mirror_url}/{version}/{scopeWithAtAndSlash}{name}-v{version}-{runtime}-v{abi}-{platform}{libc}-{arch}.tar.gz'

Custom Mirrors

The prebuildHostMirrorUrl config can be used to set a custom prebuild mirror URL.

prebuildHostMirrorUrl: 'https://custom-prebuild-mirror.com/prebuilds'

The prebuildHostMirrorTemplate config key can be used to set a custom template to fetch the prebuild tar.

The template variables injected are as follows:

{mirror_url}
{name}
{version}
{abi}
{runtime}
{platform}
{arch}
{libc}
{tag_prefix}
{scope}
{scopeWithAt}
{scopeWithAtAndSlash}
{scopeWithSlash}

For example

prebuildHostMirrorTemplate: '{mirror_url}/{scopeWithAtAndSlash}{name}-v{version}-{runtime}-v{abi}-{platform}{libc}-{arch}.tar.gz'

The default template is:

{mirror_url}/{tag_prefix}{version}/{name}-v{version}-{runtime}-v{abi}-{platform}{libc}-{arch}.tar.gz

Scoped configuration

Configuration can be done per scope with the prebuildScopes config key.

prebuildScopes:
  '@serialport':
    prebuildTagPrefix: '@serialport/bindings@'
