Package Exports
- p3x-angular-http-cache-interceptor
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (p3x-angular-http-cache-interceptor) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

9.1.4Description
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 caching all, with the exception when you the CachingHeaders.NoCache header into your request (with any data you specify).

How to use it
npm i p3x-angular-http-cache-interceptor object-hash @types/object-hashInclude the caching interceptor into you Angular module
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:
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)
}
}

Possible, this server, rarely, is down, please, hang on for 15-30 minutes and the server will be back up.
All my domains (patrikx3.com and corifeus.com) could have minor errors, since I am developing in my free time. However, it is usually stable.
