# @loopback/example-hello-world
A simple hello-world application using LoopBack 4!
## Summary
This project shows how to write the simplest LoopBack 4 application possible.
Check out
[src/application.ts](https://github.com/strongloop/loopback-next/blob/master/examples/hello-world/src/application.ts)
to learn how we configured our application to always respond with "Hello
World!".
## Prerequisites
Before we can begin, you'll need to make sure you have some things installed:
- [Node.js](https://nodejs.org/en/) at v10 or greater
Additionally, this tutorial assumes that you are comfortable with certain
technologies, languages and concepts.
- JavaScript (ES6)
- [npm](https://www.npmjs.com/)
- [REST](https://en.wikipedia.org/wiki/Representational_state_transfer)
## Installation
1. Install the new loopback CLI toolkit.
```sh
npm i -g @loopback/cli
```
2. Download the "hello-world" application.
```sh
lb4 example hello-world
```
3. Switch to the directory.
```sh
cd loopback4-example-hello-world
```
## Use
Start the app:
```sh
npm start
```
The application will start on port `3000`. Use your favourite browser or REST
client to access any path with a GET request, and watch it return
`Hello world!`.
