reviewdog-action-tsc

This GitHub Action runs tsc with reviewdog to improve code checking and review experience for TypeScript-based modules. 🐶

The action will first run tsc, then passing the compiler's output to reviewdog for further processing. Reviewdog will then provide a GitHub check either with code annotations as displayed above or with a Pull Request review, depending on the action configuration.

For full documentation regarding reviewdog, its features and configuration options, please visit the reviewdog repository.

Usage

This example shows how to configure the action to run on any event occurring on a Pull Request. Reviewdog will report tsc output messages as warnings by opening a code review on the Pull Request which triggered the workflow.

name: reviewdog
on: [pull_request]
jobs:
  tsc:
    name: runner / tsc
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: EPMatt/reviewdog-action-tsc@v1
        with:
          github_token: ${{ secrets.github_token }}
          # Change reviewdog reporter if you need
          # [github-pr-check,github-check,github-pr-review].
          # More about reviewdog reporters at
          # https://github.com/reviewdog/reviewdog#reporters
          reporter: github-pr-review
          # Change reporter level if you need
          # [info,warning,error].
          # More about reviewdog reporter level at
          # https://github.com/reviewdog/reviewdog#reporters
          level: warning

FAQs

How do I run the action on a TS module in a subfolder?

To run the action on a TS module in a subfolder, you can change the path where the action will run with the workdir input.

name: reviewdog
on: [pull_request]
jobs:
  tsc:
    name: runner / tsc
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: EPMatt/reviewdog-action-tsc@v1
        with:
          github_token: ${{ secrets.github_token }}
          reporter: github-pr-review
          level: warning
          # The action will look for a package.json file with typescript
          # declared as a dependency located in the "foo" subfolder.
          workdir: foo

How do I run the action on multiple TS modules?

For more complex setups which require to run the action on multiple TS modules, run the action once for each single module, changing the workdir and tsc_flags inputs accordingly.

name: reviewdog
on: [pull_request]
jobs:
  tsc:
    name: runner / tsc
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      # Run action for the "submodule1" module
      - uses: EPMatt/reviewdog-action-tsc@v1
        with:
          github_token: ${{ secrets.github_token }}
          reporter: github-pr-review
          level: warning
          # The action will look for a package.json file with typescript
          # declared as a dependency located in the "submodule1" subfolder.
          workdir: submodule1
      # Run action for the "submodule2" module
      - uses: EPMatt/reviewdog-action-tsc@v1
        with:
          github_token: ${{ secrets.github_token }}
          reporter: github-pr-review
          level: warning
          # The action will look for a package.json file with typescript
          # declared as a dependency located in the "submodule2" subfolder.
          workdir: submodule2

Why can't I see the results?

Try looking into the filter_mode options explained here. TypeScript errors will sometimes appear in lines or files that weren't modified by the commit the workflow run is associated with, which instead get filtered with the default added option.
