The method and route will change based on our action. Now that we know what we’re building, let’s try to break it down into individual APIs we’re going to need. quantity - the number of items remaining in stock.id - which is the unique identifier of each item.To keep the app as simple as possible, each item will be represented by an object with three fields:

We will use MongoDB as a database to store and retrieve our data.

The Node.js application will host an HTTP server and the application logic of our APIs.

We will define a RESTful API to act as an interface between the user and our application.

Let’s look at the different components of this application: Using our API we will be able to create new items, list down their stock, and add or remove items from the stock when they’re purchased or replenished. We will use the Express library as the application server and MongoDB as the database.Īs an example, we’ll build an inventory manager application. In this post, we will build a RESTful API server from scratch with Node.js.
