# JS: Angular 11: Deprecated karma-coverage-istanbul-reporter

Starting Angular 11, the karma-coverage-istanbul-reporter has been deprecated. In order to solve this, you can use [karma-coverage](https://www.npmjs.com/package/karma-coverage).

In order to configure this, please do the following:

1. Install the karma-coverage package - `npm install karma karma-coverage`
2. Update the karma.conf.js file and modify the `coverageIstanbulReporter` to `coverageReporter` and use the `type: 'json'` find below an example of such a reporter configuration

{% code overflow="wrap" lineNumbers="true" %}

```
coverageReporter: {
      dir: 'build/reports/coverage',
      reporters: [
        { type: 'json', subdir: 'report-json' }
      ]
    },
```

{% endcode %}
