## Angular Usage

### Install dependencies
```bash
npm i @openfeature/angular-sdk @splitsoftware/splitio-browserjs @splitsoftware/openfeature-web-split-provider
```

### Initialize the Angular SDK

#### Traditional (NgModule) setup
```js
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { OpenFeatureModule } from '@openfeature/angular-sdk';
import { SplitFactory } from '@splitsoftware/splitio-browserjs';
import { OpenFeatureSplitProvider } from '@splitsoftware/openfeature-web-split-provider';

const splitFactory = SplitFactory({
core: {
authorizationKey: 'CLIENT_SIDE_SDK_KEY',
key: 'TARGETING_KEY'
}
});
const openFeatureProvider = new OpenFeatureSplitProvider(splitFactory);

@NgModule({
imports: [
RouterModule.forRoot(routes),
OpenFeatureModule.forRoot({
provider: openFeatureProvider
})
],
bootstrap: [AppComponent]
})
export class AppModule {}
```

#### Standalone (Angular 16+) setup
```js
import { ApplicationConfig, provideBrowserGlobalErrorListeners, importProvidersFrom } from '@angular/core';
import { OpenFeatureModule } from '@openfeature/angular-sdk';
import { SplitFactory } from '@splitsoftware/splitio-browserjs';
import { OpenFeatureSplitProvider } from '@splitsoftware/openfeature-web-split-provider';

const splitFactory = SplitFactory({
core: {
authorizationKey: 'CLIENT_SIDE_SDK_KEY',
key: 'TARGETING_KEY'
}
});
const openFeatureProvider = new OpenFeatureSplitProvider(splitFactory);

export const appConfig: ApplicationConfig = {
providers: [
provideBrowserGlobalErrorListeners(),
importProvidersFrom(
OpenFeatureModule.forRoot({
provider: openFeatureProvider
})
)
]
};
```

#### Component injection and usage
```js
import { FeatureFlagService, EvaluationDetails } from '@openfeature/angular-sdk';

@Component({
selector: 'app-root',
imports: [RouterOutlet],
templateUrl: './app.html',
styleUrl: './app.css'
})
export class App {
constructor(private splitService: FeatureFlagService) {}

ngOnInit() {
this.splitService.getStringDetails('featureFlagName', 'default').subscribe((result: EvaluationDetails<string>) => {
console.log('Feature flag result:', result.value);
});
}
}
```

## React usage

### Install dependencies
```bash
npm i @openfeature/react-sdk @splitsoftware/splitio-browserjs @splitsoftware/openfeature-web-split-provider
```

### Initialize the React SDK
```js
import { OpenFeature } from '@openfeature/react-sdk';
import { OpenFeatureSplitProvider } from '@splitsoftware/openfeature-web-split-provider';
import { DebugLogger, SplitFactory } from '@splitsoftware/splitio-browserjs';

const splitFactory = SplitFactory({
core: {
authorizationKey: 'CLIENT_SIDE_SDK_KEY',
key: 'TARGETING_KEY'
}
})
const openFeatureProvider = new OpenFeatureSplitProvider(splitFactory);

OpenFeature.setProvider(openFeatureProvider);

function App() {
return (
<OpenFeatureProvider>
<Page></Page>
</OpenFeatureProvider>
);
}
```

#### Evaluation hooks
```js
import { useFlag } from '@openfeature/react-sdk';

function Page() {
// Use the "query-style" flag evaluation hook, specifying a flag-key and a default value.
const { value: showNewMessage } = useFlag('new-message', true);
return (
<div className="App">
<header className="App-header">
{showNewMessage ? <p>Welcome to this OpenFeature-enabled React app!</p> : <p>Welcome to this React app.</p>}
</header>
</div>
)
}
```
