Node.js, Express, and MongoDB: Create a Restful API with image upload

What will you learn?

What will you learn by downloading my code?

• Use of express to make API creation simple
• Using Mongoose to manage communication with Mongo DB
• Image Upload with multer
• Image deletion with the notions of paths and file system in node
• Field validation using validator
• Creation of reusable methods thanks to the concept of modules
• Creation of a functional REST API with Node.js, Express, and Mongo DB.

Are you ready? Let's go

Step 1: Installing dependencies

Clone the repository then run npm install or yarn

Step 2: Link your API to Mongo DB

You can install Mongodb locally or use Mongo Atlas (online). In both cases, go to the index.js file then replace the URL mongodb://localhost:27017/blog with your URL into the .env file. In my case, I use Mongo DB locally. It is therefore available on port 27017(by default) and the name of my database is blog. Also, you will use the MongoDB cluster.

Step 3: Launch your project

To launch your project, just type the following command: npm run server or yarn server. Your API will therefore run on port 8000
