## What it is
A Webpack plugin that runs TypeScript type checking in a separate worker process to speed up builds. It supports project references, incremental mode, and nice code-frame error messages.

## Use cases
- speed up webpack builds with typescript type checking
- run tsc type checker in a separate process during webpack build
- type check typescript without blocking webpack compilation
- add typescript checking to ts-loader webpack setup
- check typescript project references incrementally in webpack
- show pretty typescript errors with code frames in webpack

## When to choose
- you use webpack 5 with ts-loader or babel-loader and want faster type checking
- your webpack builds are slowed down by synchronous TypeScript checking
- you want incremental TypeScript checking with project references support

## When to avoid
- you use webpack 4 or older TypeScript (use plugin version 6 instead)
- you need Vue.js support (use version 6)
- you don't use webpack as your bundler
