About this tool

Converts established ESLint configuration files into a format compatible with Biome, modernizing linting rulesets for JavaScript and TypeScript projects. Maps over one hundred common coding rules originating from core JavaScript, TypeScript, React, and various import plugins. Users input their existing, complex ESLint rule definitions, and the tool generates the corresponding structure needed to implement those same checks using Biome’s syntax. This process helps maintain code quality standards while transitioning development environments. Developers upgrading their tooling stack or adopting Biome as their preferred linter utilize this utility. It significantly streamlines the migration effort by automating the painstaking task of manually translating detailed, multi-plugin ESLint configurations into Biome's structure.
