# Description
[//]: #@corifeus-header:end
<!--
Based on [@d4h/angular-http-cache](https://www.npmjs.com/package/@d4h/angular-http-cache), but it works without any configuration and a different implementation, so they are not the same at all, but the idea is the same.
-->
Usually, you do not cache all requests, but only the `GET` method. But, some clients, it is required to cache everything, including all methods. So this micro-service does that.
There is room in the future, to restrict to specific methods and more configurations, if there is a request for this micro-service, but for now it is an all or nothing (if you add in the `CachingHeaders.NoCache`.
# Example web page that uses this package
https://angular-http-cache-interceptor.corifeus.com
# How to use it
```bash
npm i p3x-angular-http-cache-interceptor object-hash @types/object-hash
```
## Include the caching interceptor into you Angular module
```js
import { NgModule } from '@angular/core';
import { P3XHttpCacheInterceptorModule } from 'p3x-angular-http-cache-interceptor';
@NgModule({
declarations: [
],
imports: [
P3XHttpCacheInterceptorModule,
],
providers: [
],
bootstrap: []
})
export class SomeModule { }
```
## Example invocation in a component
With and without cache:
```ts
import { Component } from '@angular/core';
import { HttpClient } from "@angular/common/http";
import {MatSnackBar} from "@angular/material/snack-bar";
import { CachingHeaders } from 'p3x-angular-http-cache-interceptor'
@Component({
selector: 'p3x-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent {
constructor(
private http: HttpClient,
private snack: MatSnackBar,
) {
}
async loadCached() {
try {
const response : any = await this.http.get('https://server.patrikx3.com/api/core/util/random/32').toPromise()
this.snack.open(`Will be always the same: ${response.random}`, 'OK')
} catch(e) {
this.snack.open(`Sorry, error happened, check the consle for the error`, 'OK')
console.error(e)
}
}
async loadNonCached() {
try {
const response : any = await this.http.get('https://server.patrikx3.com/api/core/util/random/32', {
headers: {
[CachingHeaders.NoCache]: '1'
}
}).toPromise()
this.snack.open(`Truly random data: ${response.random}`, 'OK')
} catch(e) {
this.snack.open(`Sorry, error happened, check the console for the error`, 'OK')
console.error(e)
}
}
}
```
