Aurelia - HTTP

In this chapter, you will learn how to work with HTTP requests in Aurelia framework.

Step 1 - Create a View

Let's create four buttons that will be used for sending requests to our API.

app.html

<template>
   <button click.delegate = "getData()">GET</button>
   <button click.delegate = "postData()">POST</button>
   <button click.delegate = "updateData()">PUT</button>
   <button click.delegate = "deleteData()">DEL</button>
</template>

Step 2 - Create a View-model

For sending requests to the server, Aurelia recommends fetch client. We are creating functions for every requests we need (GET, POST, PUT and DELETE).

import 'fetch';
import {HttpClient, json} from 'aurelia-fetch-client';

let httpClient = new HttpClient();

export class App {
   getData() {
      httpClient.fetch('http://jsonplaceholder.typicode.com/posts/1')
      .then(response => response.json())
      .then(data => {
         console.log(data);
      });
   }
   myPostData = { 
      id: 101
   }
	postData(myPostData) {
      httpClient.fetch('http://jsonplaceholder.typicode.com/posts', {
         method: "POST",
         body: JSON.stringify(myPostData)
      })
		
      .then(response => response.json())
      .then(data => {
         console.log(data);
      });
   }
   myUpdateData = {
      id: 1
   }
	updateData(myUpdateData) {
      httpClient.fetch('http://jsonplaceholder.typicode.com/posts/1', {
         method: "PUT",
         body: JSON.stringify(myUpdateData)
      })
		
      .then(response => response.json())
      .then(data => {
         console.log(data);
      });
   }
   deleteData() {
      httpClient.fetch('http://jsonplaceholder.typicode.com/posts/1', {
         method: "DELETE"
      })
      .then(response => response.json())
      .then(data => {
         console.log(data);
      });
   }
}

We can run the app and click GET, POST, PUT and DEL buttons, respectively. We can see in the console that every request is successful, and the result is logged.
