# NoEmitOnErrorsPlugin

`NoEmitOnErrorsPlugin` prevents Rspack from emitting assets when a compilation contains errors. Setting [`optimization.emitOnErrors`](/config/optimization.md#optimizationemitonerrors) to `false` applies this plugin internally.

## Examples

The following development configuration keeps the previous files in `dist` unchanged when the new compilation has an error:

```js title="rspack.config.mjs"
import { rspack } from '@rspack/core';

export default {
  mode: 'development',
  entry: './src/index.js',
  plugins: [new rspack.NoEmitOnErrorsPlugin()],
};
```

For example, if `src/index.js` contains a syntax error, Rspack reports the error without writing assets from that compilation. The equivalent configuration is `optimization.emitOnErrors: false`.
