no-named-export

💼 This rule is enabled in the following configs: recommended, typescript.

Rule DetailsCopy Anchor Link

A convention: every module publishes one default export and nothing else. This rule reports every value named export:

• export const / let / var (also destructured, one per bound name), export function, export class, export enum;
• an export list, also renamed or under a string name (export { b as "a" });
• export { a } from 'm', export * from 'm' (it publishes every name of m) and export * as ns from 'm'.

Not reported: anything exported as default (export { x as default }, export * as default from 'm'); type-only exports (export type, export interface, export type { T }, export { type T }, export const enum); a bare export {}.

❌ IncorrectCopy Anchor Link

export const a = 1;
export enum Color {
  Red,
}
export * from './utils';

✅ CorrectCopy Anchor Link

export default function load() {}
export type Options = { retries: number };
const a = 1;
export { a as default };

• allowNames (default []): exported names that are accepted. export * from 'm' publishes names the file cannot see and is never covered by this list.
• allowInFiles (default []): file globs (or path substrings) where named exports are accepted.
• allowPatterns (default []): more file globs (or path substrings), same meaning as allowInFiles.
• suggestDefault: has no effect; accepted so existing configs keep validating.

A glob matches any run of whole path segments, so src/*.test.ts matches an absolute filename.

When Not To Use ItCopy Anchor Link

In most codebases: named exports are the common convention. Use it only where a framework requires a single default export per file.
