@yarnpkg/plugin-typescript

Features

• Automatically adds @types/ packages into your dependencies when you add a package that doesn't include its own types
• Adds support for types to publishConfig (same behavior as publishConfig.bin)

Install

yarn plugin import typescript

Example

❯ yarn/packages/plugin-typescript ❯ yarn add lodash

As you can see in the fetch step, even though we only added lodash into our dependencies, Yarn automatically figured out that we would need @types/lodash, and added it before we ask it to.
