Motivation

Until this ☂️ Type-aware linter · Issue #3187 · biomejs/biome is resolved, we continue to use @typescript-eslint/parser and @typescript-eslint/eslint-plugin to lint TypeScript files.

Recommended Rules

Add the following recommended rules to your ESLint configuration for effective linting of TypeScript files:

{
  "@typescript-eslint/await-thenable": "error",
  "@typescript-eslint/no-floating-promises": "error",
  "@typescript-eslint/no-for-in-array": "error",
  "@typescript-eslint/no-misused-promises": "error",
  "@typescript-eslint/no-redundant-type-constituents": "error",
  "@typescript-eslint/no-unnecessary-type-assertion": "error",
  "@typescript-eslint/require-await": "error"
}

# Install eslint-fixer
