What Is an .eslintrc file?
an .eslintrc file explained, including what it does and how it matters in CI/CD.
An .eslintrc (or eslint.config.js for flat config) file configures ESLint linting rules.
What it is
It defines which rules, plugins, and parser options apply. ESLint reads it to flag code-quality and style issues.
Why it matters in CI/CD
CI runs ESLint as a gate, often with --max-warnings 0 so any warning fails the build. A missing plugin or parser in the config is a frequent CI failure.
Key takeaways
- .eslintrc configures ESLint.
- It sets rules, plugins, and parser.
- CI lints with --max-warnings 0.
