yarn-plugin-after-install

This is a Yarn v4 plugin that adds support for an afterInstall hook that runs after every yarn install, regardless of whether dependencies have changed.

For Yarn v3 support, install v0.5.0 or earlier.

Inspired by https://github.com/GravitywellUK/yarn-plugin-postinstall.

Install

yarn plugin import https://raw.githubusercontent.com/mhassan1/yarn-plugin-after-install/v0.7.0/bundles/@yarnpkg/plugin-after-install.js

Usage

1. Add an afterInstall hook in .yarnrc.yml:

# .yarnrc.yml

afterInstall: do-something-awesome

The script will run relative to the project directory (containing .yarnrc.yml).

The script will be passed an environment variable (_YARN_PLUGIN_AFTER_INSTALL_COMMAND_ARGV) that contains a JSON array of arguments passed to yarn in the original command (for example, if the user runs yarn install, the script will be passed _YARN_PLUGIN_AFTER_INSTALL_COMMAND_ARGV=["install"]).

2. Run yarn.

Testing

yarn test

NOTE: Integration tests require yarn build first.
