name: Compressed Size

on: [pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write
      contents: read
    steps:
      - uses: actions/checkout@v2
      - uses: ./.github/actions/size
        with:
          strip-hash: "\\-(\\w{8})\\.js$"
          compression: "none"
          build-script: "build:notsc"

before: If the fileName remains unchanged after the stripHash function(index-efdcc4d5.js -> index-.js, index-bc581656.js -> index-.js and other index files), the file size will only be calculated once.

after: file size should be calculated together.
