bundle-size-action

In order to add bundle size badges to your readme automatically, add the following GitHub Action.

- uses: mikeal/bundle-size-action@master
- uses: mikeal/publish-to-github-action@master
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

The first action creates a new bundle, minifies it, and inserts/modifies the badges in the readme. The second action publishes changed files back to GitHub, which in this case is the README.md that was just modified.

You probably want to run this at the end of your regular build/test cycle on master.

Known projects using this are:

• bent
• bytesish
• digestif
