A GitHub Action that runs ESLint with reviewdog to automatically post code review comments on pull requests.
reviewdog/action-eslint is a GitHub Action that runs ESLint with reviewdog to automatically analyze code changes in pull requests. It detects JavaScript and TypeScript linting issues and posts them as review comments, helping teams maintain code quality during code reviews. The action integrates directly into GitHub's workflow to provide immediate feedback on proposed changes.
Development teams using GitHub for collaboration who want to automate code quality checks during pull request reviews. It's particularly useful for JavaScript/TypeScript projects that already use ESLint and want to integrate it into their CI/CD pipeline.
Developers choose this action because it provides a seamless integration between ESLint and GitHub's review system, saving time during code reviews by automatically surfacing linting issues. Unlike basic ESLint CI checks, it offers flexible reporting options and contextual comments that make it easier to address issues directly in the pull request interface.

Posts ESLint findings as inline comments on GitHub pull requests using reviewdog, providing immediate contextual feedback during code reviews, as demonstrated in the example workflows.
Supports multiple reviewdog reporters like github-pr-review for markdown comments and github-check for status checks, allowing teams to tailor feedback to their workflow preferences.
Inputs such as `level` and `fail_level` let you set issue severity and failure thresholds, offering granular control over code quality gates without hard failures.
Can run in matrix jobs with unique `tool_name` inputs, enabling distinct checks for different Node.js versions or environments, as shown in the README's matrix example.
Requires separate ESLint installation and configuration, as noted in the README's example usage, adding steps to the setup process compared to all-in-one solutions.
Relies on reviewdog for reporting, introducing an extra tool that teams unfamiliar with it must learn and maintain, potentially increasing complexity.
Specifically designed for ESLint, so projects using other linters like stylelint or markdownlint require separate actions or custom integrations.
