Question 1

How to set up reviewdog action eslint for a TypeScript project?

Accepted Answer

Ensure your ESLint configuration includes TypeScript plugins and parsers, then run the action with `eslint_flags` pointing to your source directories. The action works with TypeScript out of the box if ESLint is properly configured.

Question 2

reviewdog action eslint vs super-linter for JavaScript codebases?

Accepted Answer

Super-linter supports multiple languages and linters but can be slower and less customizable for ESLint. reviewdog/action-eslint is more focused, offering better GitHub PR comment integration and flexible reporting for ESLint-specific needs.

Question 3

Can I use this action to lint only changed files in a pull request?

Accepted Answer

Yes, use the `filter_mode` input set to 'added' or 'diff_context' to limit ESLint analysis to files changed in the PR, improving performance by avoiding full codebase scans.

Question 4

How to configure reviewdog action eslint to fail on warnings?

Accepted Answer

Set the `fail_level` input to 'warning' instead of the default 'none'. This will cause the CI check to fail if any issues with severity warning or higher are found, enforcing stricter code quality.

Question 5

What permissions are needed in GitHub for reviewdog action eslint to work?

Accepted Answer

As shown in the example workflow, you need to set permissions for pull-requests: write to post comments and contents: read to access the code. Adjust these in your GitHub Actions YAML file.

Question 6

Does reviewdog action eslint support custom ESLint rules or plugins?

Accepted Answer

Yes, as long as the rules or plugins are installed in your project's dependencies and configured in your .eslintrc file. The action runs ESLint with your setup, so compatibility depends on your ESLint environment.
