Package Exports

@yarnpkg/plugin-typescript

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@yarnpkg/plugin-typescript) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

`@yarnpkg/plugin-typescript`

This plugin automatically adds @types/ packages into your dependencies when you add a package that's covered by one.

Note that for performance reasons the plugin doesn't try to check whether the added package contains its own types - so you might end up with extraneous type packages in some cases.

Usage

Note: This plugin (as all other Yarn plugins) is only compatible with Yarn 2. Yarn 2 is still in a "developer preview" state, meaning that you're welcome to use it and give us your feedback but you might have to get your hands a little dirty to dive into the mechanic.

Install Yarn

Install the @yarnpkg/plugin-typescript plugin:

$ yarn plugin import @yarnpkg/plugin-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.
