yarn-check-webpack-plugin

library1.2.0jsnpmunverified

A webpack plugin that verifies there are no missing or outdated yarn dependencies during development. The plugin runs `yarn check --integtrity` as a webpack compilation hook and displays warnings for missing or wrong version packages. It is designed for large codebases where dependencies change frequently across branches. The current stable version is 1.2.0, but the package appears in maintenance mode (last release in 2019). It is type-safe with TypeScript types included. Exclusive in its integration of yarn's dependency checking directly into the webpack build lifecycle, differentiating it from lint-based or separate CLI approaches.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

YarnCheck

✓ import { YarnCheck } from 'yarn-check-webpack-plugin'

✗ import YarnCheck from 'yarn-check-webpack-plugin'

Named export (not default) in both ESM and CommonJS.

YarnCheck

✓ const { YarnCheck } = require('yarn-check-webpack-plugin')

CommonJS require also supported.

YarnCheckOptions

✓ import { YarnCheckOptions } from 'yarn-check-webpack-plugin'

Type import available.

Basic setup showing CommonJS require, plugin instantiation with optional config (rootDirectory and exclude), and conditional 'forceKill' option.

// webpack.config.js const { YarnCheck } = require('yarn-check-webpack-plugin'); module.exports = { // ... other config plugins: [ new YarnCheck({ rootDirectory: __dirname, exclude: /some-package/ }) ] };

Debug

Known issues

deprecatedyarn check --integtrity has been removed in Yarn 2+ (Berry). The plugin will not work with Yarn >=2.

fix

Use yarn-plugin or upgrade to a tool like 'check-dependencies', or stay on Yarn Classic.

affects: >=2.0.0-yarn

breakingIn version 1.2.0, the 'forceKill' option was added. If you used an earlier version, your config object might be missing this property – safe to ignore.

fix

Add 'forceKill' property if needed, otherwise it's optional.

affects: <1.2.0

gotchaThe plugin only runs when yarn.lock is present; if using npm or pnpm, it will silently no-op.

fix

Use the appropriate plugin for your package manager (e.g., npm-check-webpack-plugin).

affects: >=1.0.0

gotchaThe plugin runs a spawn of 'yarn check' on every compilation. This can add overhead in large projects.

fix

Consider using a watch mode filter or only run in development.

affects: >=1.0.0
