## :books: General info
* Code from Angular Boot Camp tutorial (see Inspiration below) on correct use of RxJS
## :camera: Screenshots
## :signal_strength: Technologies
* [Angular framework v16](https://angular.io/)
* [RxJS v7](https://rxjs.dev/) Reactive Extensions Library for JavaScript
* [reddit API documentation](https://www.reddit.com/dev/api/)
## :floppy_disk: Setup
* Install dependencies with npm install.
* Run app using `ng serve` then navigate to `http://localhost:4200/`.
## :computer: Code Examples
* `reddit-search.component.ts` function using RxJS switchmap to combine 2 observable data streams and return a new observable
```typescript
this.results = combineLatest([validSubReddit, validSearch]).pipe(
// This logs the user's intended search
tap(search => this.logger.log('Search for: ' + search)),
// take an input observable, return a different observable
switchMap(([subReddit, search]) =>
ris.search(subReddit, search).pipe(
retry(3),
// Clear previous entries while waiting
startWith([])
)
)
);
```
## :cool: Features
* RxJS methods reduce unnecessary HTTP data requests
## :clipboard: Status & To-Do List
* Status: Working but with strict mode turned off
* To-Do: Correct types and reactivate strict mode.
