@spscommerce/eslint-config-typescript-flat

An ESLint 9/10 flat-config-only version of SPS Commerce's TypeScript style guide (see below for the style guide contents)

Flat-config successor to @spscommerce/eslint-config-typescript. Use this package if your project has already migrated to flat config (eslint.config.js/.mjs) and you're on ESLint 9 or 10. If you're still on .eslintrc-style config, stay on @spscommerce/eslint-config-typescript - ESLint 10 removed .eslintrc support entirely, so there's no flat/legacy split in this package the way there is in that one; it's flat-only, full stop.

The rule set is intentionally a duplicate of @spscommerce/eslint-config-typescript's at the time this package was created, not a shared dependency between the two - each package's rules can now evolve independently.

You probably want to read the guide.

// eslint.config.js
import spsConfig from '@spscommerce/eslint-config-typescript-flat';

export default [
  ...spsConfig,
  // your custom config
];
