Build a CRUD Rest API in JavaScript using Nodejs, Express, Postgres, …

Let’s create a CRUD rest API in JavaScript, using:

• Node.js
• Express
• Sequelize
• Postgres
• Docker
• Docker Compose

If you prefer a video version:

Here is a schema of the architecture of the application we are going to create:

We will create 5 endpoints for basic CRUD operations:

• Create
• Read all
• Read one
• Update
• Delete

We will create a Node.js application using:

• Express as a framework
• Sequelize as an ORM

1. We will Dockerize the Node.js application

2. We will have a Postgres istance, we will test it with Tableplus

3. We will create a docker compose file to run both the services

4. We will test the APIs with Postman

Here is a step-by step guide.

create a new folder

mkdir node-crud-api

step into it

cd node-crud-api

initialize a new npm project

npm init -y
