ng.http

A Reactive HTTP module for Angular. Reactive? Yes, I super-charged the module with the RxJS library.

RxJS is a library that brings Reactivity (notion of data/events over time) to JavaScript.

RxJS stands for __R__eactive E__x__tensions for __J__ava__S__cript.

This is my own implementation/clone of the Angular HTTP module.

Installation

You can pull in from NPM using the command:

npm i ng.http.lib -S

Using yarn:

yarn add ng.http.lib

Yeah, I know, the name looks weird and with the double dots, its kind of creepy, I would say. I originally named it ng_http, but I couldn't publish with the name 'cos of too many similiar names on NPM, so I had to conjure up that.

Usage

Import the HttpModule in app.module.ts file:

// app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations'
 
import { AppComponent } from './app.component';
import { HttpModule } from 'ng.http.lib'
 
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    HttpModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Http class was implemented. Like in the official Angular HTTP module, it has methods for CRUDy requests:

  • get
  • post
  • delete
  • put
  • patch

Though, I only implemented the get method. Don't worry, I'll fix other methods or you can help by contributing to the project. I built this module just to demonstrate how Angular modules work and how RxJS (Reactive Programming) was incorporated into the HTTP module unlike other Promise-based HTTP libraries we have always seen (axios etc.).

The Http class is available to the whole Angular app because it was added to HttpModule's providers array. So you do not have to re-import it in your own sub-modules. So, inorder to use HTTP methods, import it in your Component/Directive/Service like this:

import { Component, OnInit } from '@angular/core';
import { Http } from 'ng.http.lib'
 
@Component({
  selector: 'app-todo',
  template: `
    <p>
      todo works!
    </p>
    <button (click)="see()">See</button>
  `,
  styles: []
})
export class TodoComponent implements OnInit {
 
  constructor(private http: Http) { }
 
  see() {
    this.http.get('http://localhost:3000/api')
      .subscribe((v) => alert(v),err=>alert(`Error`))
  }
}

You see the this.http.get method returns an Observable, which we subscribe to the stream, to get our values.
