ESLint v10 breaking changes flat config migration guide
💡 Result:
ESLint v10.0.0 was released on February 6, 2026, marking the complete removal of the legacy.eslintrc configuration system in favor of the flat configuration format [1][2]. Projects must now use eslint.config.js (or.mjs/.cjs) as their configuration file [1][3]. Key Breaking Changes and Migration Requirements: 1. Removal of Legacy Config Support: The.eslintrc,.eslintrc.json,.eslintrc.js, and.eslintrc.yml files are no longer supported [3][4]. The environment variable ESLINT_USE_FLAT_CONFIG has been removed, making flat config mandatory [1][3]. 2. Node.js Version Requirements: ESLint v10 requires Node.js versions ^20.19.0, ^22.13.0, or >=24. Older versions of Node.js are no longer supported [1][5][2]. 3. Configuration Structure: - The ignores property in the flat config array now handles file ignoring, replacing the separate.eslintignore file [3][4]. - The --env CLI flag and /* eslint-env / comments are no longer supported; environments must now be configured using the globals package within languageOptions [4]. - Legacy plugins and configs (like those using extends or --rulesdir) must be imported directly into the flat config array [3][4]. The @eslint/eslintrc package remains available if you need to use FlatCompat to bridge legacy configs during transition [6]. 4. Notable API and Internal Changes: - The stylish formatter now uses native styleText instead of chalk [1][5]. - The LintMessage objects no longer contain a nodeType property [1][2]. - eslint:recommended has been updated, and JSX reference tracking is now enabled [1][5]. - Program range now spans the entire source text [2]. Migration Steps: - Identify and remove all.eslintrc. and.eslintignore files [4]. - Create an eslint.config.js file and export an array of configuration objects [6][7]. - Migrate ignore patterns into the ignores property of your flat config [3][4]. - Update any dependencies (such as typescript-eslint) to versions compatible with ESLint v10 (e.g., typescript-eslint v8+) [3]. - Run the ESLint configuration migrator tool to generate a starting point for your new configuration [6][3]. For comprehensive instructions, consult the official ESLint migration guide at https://eslint.org/docs/latest/use/migrate-to-10.0.0 [1].

Major: ESLint 10 upgrade needs flat-config + plugin compatibility checks
- ESLint v10 removes legacy
.eslintrc*/.eslintignoresupport and changes env/ignore handling for flat config; ensure your flat config (eslint.config.*) usesignoresandlanguageOptions.globals(noeslint-env/--env). - Plugin compatibility is mixed:
@typescript-eslint/*,eslint-plugin-functional, andeslint-plugin-jsdocadvertise peer support that includes ESLint^10, buteslint-plugin-import’s peer dependency list does not include ESLint^10(so updateeslint-plugin-importto a v10-compatible release if you’re on the^2.xline). - Since CI runs
npm run lint, also confirm CI/package.jsonNode version meets ESLint v10’s requirements.
