Description

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, it could be enhanced, but for now, it is caching all, with the exception when you include the CachingHeaders.NoCache header into your request (with any data you specify, see how it works below).

How to use it

npm i p3x-angular-http-cache-interceptor object-hash @types/object-hash

Include 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.

Note about versioning: Versions are cut in Major.Minor.Patch schema. Major is always the current year. Minor is either 4 (January - June) or 10 (July - December). Patch is incremental by every build. If there is a breaking change, it should be noted in the readme.
