@studnicky/canonical-export-names

Disallows renaming symbols at the export site (export { foo as bar }) and disallows any non-index re-export path. Outside index files (index.ts, index.mts, etc.), the rule forbids direct re-exports (export { Foo } from './foo.js'), star re-exports (export * from './foo.js'), and forwarding an imported binding (import { Foo } from './foo.js'; export { Foo };). The same restriction applies to type-only imports and exports.

Fixable: No · Options: No · Suggested severity: error

✗ Incorrect

// ✗ userService.ts — renaming at export site
export { MyClass as TheClass };

// ✗ userService.ts — re-export outside an index file
export { MyClass } from './myClass.js';

// ✗ userService.ts — star re-export outside an index file
export * from './helpers.js';

// ✗ userService.ts — import then export still re-exports
import { MyClass } from './myClass.js';
export { MyClass };

✓ Correct

// ✓ index.ts — forwarding the canonical name unchanged
export { MyClass } from './MyClass.js';
export { UserService } from './UserService.js';

// ✓ index.ts — star re-export is permitted in index files
export * from './types.js';
