# no-self-import

[Added in v0.1.8](https://github.com/web-infra-dev/rslint/releases/tag/v0.1.8)
## Configuration


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

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

## Rule Details

Disallows a module from importing itself. A module that imports itself creates a circular dependency on itself, which is always a mistake and can cause confusing runtime behavior or errors. This applies to both ES module `import` statements and CommonJS `require()` calls.

Loading the current file through a known text or JSON attribute view is not a self module import because that request does not execute the file as JavaScript.

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

```javascript
// in file "foo.js"
import foo from './foo';

// in file "index.js"
const index = require('./index');
```

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

```javascript
// in file "foo.js"
import bar from './bar';

// in file "index.js"
const utils = require('./utils');
```
