Angular 5 HTTP Client Demo App

This is a demo application showing how to use the HttpClient service and Observables in Angular 5.

For background on the topic of Angular HTTP requests, please see my blog posts:

Note: This app uses the new and improved HttpClient service introduced in Angular 4.3. If you are using Angular 2 or Angular 4 v4.2 and below, see this older demo using the deprecated Http service.

What's in here

• app.js - a simple Express app which acts as the back-end API.
• src/app/ - this folder contains the Angular app
• config/ - this folder contains webpack-related scripts

Running the app

To run this application, you need NodeJS and NPM installed on your system. Then, run the following commands from your command prompt:

npm install
npm start

This will transpile the TypeScript files, bundle everything using Webpack, and start the Node server. The app will be available at http://localhost:3000/
