- **Type:** `string[] | undefined`
- **Default:**

```ts
const defaultBrowserListMap: Record<RsbuildTarget, string[]> = {
  web: ['chrome >= 87', 'edge >= 88', 'firefox >= 78', 'safari >= 14'],
  node: ['node >= 14'],
  'web-worker': ['chrome >= 87', 'edge >= 88', 'firefox >= 78', 'safari >= 14'],
};
```

Specifies the range of target browsers that the project is compatible with.

This value will be used by [SWC](https://github.com/swc-project/swc) and [autoprefixer](https://github.com/postcss/autoprefixer) to identify the JavaScript syntax that need to be transformed and the CSS browser prefixes that need to be added.

For other configuration methods and configuration priorities, please refer to the [Browserslist configuration](/guides/advanced-features/compatibility.md).
