My pull request adding TypeScript tooling and configuration for emotion was merged. This is an important step in the process of rewriting emotion in TypeScript.

The pull request contained a number of changes:
  • Configuring babel to support TypeScript
  • Changing the eslint parser to @typescript-eslint/parser
  • Updating the eslint configuration to target TypeScript files
  • Adding a root tsconfig.json file which is used by various packages

Many thanks to Josh Goldberg and Andarist for their detailed feedback and helping me move the PR along.
