# no-named-as-default

[Added in v0.9.4](https://github.com/web-infra-dev/rslint/releases/tag/v0.9.4)
## Configuration

| Preset                             | Configured Value |
| ---------------------------------- | ---------------- |
| ✅ importPlugin.configs.recommended | `"warn"`         |


```ts title=rslint.config.ts
import { defineConfig, importPlugin } from '@rslint/core';

export default defineConfig([
  importPlugin.configs.recommended,
  {
    rules: {
      'import/no-named-as-default': 'error',
    },
  },
]);
```

## Rule Details

Reports a default import whose local name is also a named export of the imported module. This can indicate a missing pair of braces around a named import.

Given this module:

```javascript
// fruit.js
export default 'apple';
export const pear = 'pear';
```

Examples of **incorrect** code for this rule:

```javascript
import pear from './fruit.js';
```

Examples of **correct** code for this rule:

```javascript
import fruit from './fruit.js';
import { pear } from './fruit.js';
```

Unresolved and ignored modules, modules without a default export, and files using only CommonJS exports are skipped. TypeScript `export =` assignments available as default imports are also checked. Like upstream v2.32.0, the rule permits a name when both it and the default are explicit re-exports from the same file. Exporting the same local value under both names does not receive this exemption.

## Options

This rule has no options. It does not provide automatic fixes or suggestions.

## Differences from upstream

- When both `languageOptions.parserOptions.project` and `projectService` are
  disabled, only imported files also selected for linting can be checked. For
  example, linting `app.ts` alone does not check names exported by `lib.ts`.
  Enable either project option to check dependencies without linting them directly.
- Babel's experimental `export name from './module'` syntax is not supported.
  Use `export { default as name } from './module'` instead; this standard syntax
  is not checked by this rule, matching upstream.
- Syntax errors in imported files are not reported by this rule. For example,
  importing a file containing `return; export {};` produces a parse-error report
  upstream, but no report from this rule. Check the imported file's syntax separately.
- Quoted re-export names can produce reports that upstream misses. For example,
  given a module with `export default 1; export { foo as 'foo' } from './base'`,
  rslint reports `import foo from './module'`; upstream v2.32.0 does not.
  Quoting `default` or the name being re-exported also does not prevent rslint
  from checking for a name collision.
- rslint does not report an import just because its name matches a member of
  a re-exported namespace. For example, if `module.js`
  contains `export default 1; export * as names from './base'`, a named export
  `foo` in `base.js` does not make `import foo from './module'` an error.
  Upstream v2.32.0 reports this case.
- `esModuleInterop` does not supply a missing ES module default. Given only
  `export const foo = 1` in `values.mjs`, rslint skips
  `import foo from './values.mjs'` because there is no default-name collision.
  Enable `import/default` to report the missing default. With
  `esModuleInterop: true`, upstream v2.32.0 reports a collision instead.
- With NodeNext, native ES imports of CommonJS modules receive `module.exports`
  as their default, regardless of `esModuleInterop`. For example, if
  `values.cts` exports `const foo`, `import foo from './values.cjs'` in an
  `.mts` file is checked for a name collision even when interop is omitted
  or disabled. Upstream v2.32.0 requires explicit `esModuleInterop: true`.
