@loopback/example-todo-list

This is an extended tutorial that builds on top of @loopback/example-todo.

Overview

This tutorial demonstrates how to create a set of APIs for models that are related to one another.

Setup

If you’re following from the tutorial in @loopback/example-todo, you can jump straight to our first step: Add TodoList model

If not, you’ll need to make sure you have a couple of things installed before we get started:

• Node.js at v8.9 or greater

Next, you’ll need to install the LoopBack 4 CLI toolkit:

npm i -g @loopback/cli

We recommend that you start with the todo tutorial if you’re not familiar with LoopBack4, but if you are and don’t want to start from scratch again, you can use the LoopBack 4 CLI tool to catch up to where this tutorial will continue from:

lb4 example todo-list

It should be noted that this tutorial does not assume the optional geo-coding step has been completed. Whether the step has been completed or not, the content and the steps listed in this tutorial remain the same.

Tutorial

Once you’re ready to start the tutorial, let’s begin by adding a TodoList model

Steps

1. Add TodoList Model
2. Add TodoList Repository
3. Add TodoList and TodoList’s Todo Controller

Try it out

If you’d like to see the final results of this tutorial as an example application, follow these steps:

1. Run the lb4 example command to select and clone the todo repository:

   $ lb4 example
   ? What example would you like to clone? (Use arrow keys)
     todo: Tutorial example on how to build an application with LoopBack 4.
   ❯ todo-list: Continuation of the todo example using relations in LoopBack 4.
     hello-world: A simple hello-world Application using LoopBack 4.
     log-extension: An example extension project for LoopBack 4.
     rpc-server: A basic RPC server using a made-up protocol.
   

2. Switch to the directory.

   cd loopback4-example-todo-list
   

3. Finally, start the application!

   $ npm start
   
   Server is running on port 3000
   

Feel free to look around in the application’s code to get a feel for how it works. If you’re interested in how it’s been built or why we do things a certain way, then continue on with this tutorial!
