Slack Clone Coding [Backend with NestJS + TypeORM]

I created a chat app with my own hands, and even developed a server!
Meet NestJS, the hottest thing these days.

In Express
With NestJS !

I was originally using Express as a server framework and Sequelize as a DB at work. But I saw a lot of mention of NestJS in the community, so I tried it out and... My eyes are wide open👀!
After that , we converted all company services to NestJS, and also converted Sequelize to TypeORM.

Spring of the node system,
Hot NestJS 🔥

NestJS, called the Spring of Node.js! It is said that even developers who left Node to do Spring are coming back because of NestJS. How is NestJS different from Express, which has been widely used so far, and how powerful is it? In this lecture, we will introduce the functions of NestJS. We will convert the web server built with Express to NestJS, and directly create the backend part of a web app similar to Slack.

Well then, let’s learn first-hand why NestJS is so hot.

I recommend this to these people!

For those who want to get started with Node.js server development with NestJS
