## What it is
TypeSync is a CLI tool that scans your package. and installs missing TypeScript type definition (@types) packages for your dependencies. It supports dry runs, ignore lists, config files, and CI failure modes.

## Use cases
- add missing @types packages for my dependencies
- sync typescript typings with package. automatically
- check for missing type definitions in CI
- install typings after adding a new npm package
- ignore certain packages when syncing types
- run typesync after every npm install

## When to choose
- you maintain a TypeScript project with many untyped npm dependencies
- you want to automate keeping @types packages in sync
- you want a CI check that fails when typings are missing

## When to avoid
- your project is plain JavaScript with no TypeScript
- you manage typings manually or use packages that bundle their own types
