# Features
|
|
|
|
You can get the value of a feature on the client-side using the [config state service](./Config-State.md) if it is allowed by the feature definition on the server-side.
|
|
|
|
> This document explains how to get feature values in an Angular application. See the [Features document](../../Features.md) to learn the feature system.
|
|
|
|
## Before Use
|
|
|
|
To use the `ConfigStateService`, you must inject it in your class as a dependency. You do not have to provide the service explicitly, because it is already **provided in root**.
|
|
|
|
```js
|
|
import { ConfigStateService } from '@abp/ng.core';
|
|
|
|
@Component({
|
|
/* class metadata here */
|
|
})
|
|
class DemoComponent {
|
|
constructor(private config: ConfigStateService) {}
|
|
}
|
|
```
|
|
|
|
## How to Get a Specific Feature
|
|
|
|
You can use the `getFeature` method of `ConfigStateService` to get a specific feature from the configuration state. Here is an example:
|
|
|
|
```js
|
|
// this.config is instance of ConfigStateService
|
|
|
|
const defaultLang = this.config.getFeature("Identity.TwoFactor");
|
|
// 'Optional'
|
|
```
|
|
|
|
You can then check the value of the feature to perform your logic. Please note that **feature keys are case-sensitive**.
