Setup Express in TypeScript with Node.js - A simple example of a server using Express in TypeScript with Node.js. Set up the server and debug environment in a few minutes. We change into the directory with cd typescript-express and set up the project.
In this article, I will explain the simple step by step process of creating a new server with Express in TypeScript.
This example requires basic knowledge of Node.js, npm and Visual Studio Code.
Before we get started, we need to create a directory for our project. For this we enter
mkdir typescript-express and confirm with Enter.
We change into the directory with
cd typescript-express and set up the project.
First, we create a Node.js package with the command
npm init -y.
After that we can install the modules for our project. Therefore we install Express with
npm i express.
Since we are working in TypeScript, we also need TypeScript and Typings for Express. We do that with the command
npm i -D typescript @types/express.
Last but not least, let’s create the configuration for TypeScript. For this we use the command
npx tsc --init. The TypeScript compiler will create a predefined file with all possible settings.
Here all commands one after the other…
mkdir typescript-express cd typescript-express npm init -y npm i -D typescript @types/express npm i express npx tsc --init
For more information on setting up a project for TypeScript, I can only refer to one of my previous article Simple setup for your next TypeScript project.
Having all your workflow driven by your IDE can be a massive time saver. In this lesson we look at how you can build and debug a NodeJS application written in TypeScript using only VSCode 🌹
This article is the first part of building a production grade nodejs,graphql and typescript server with auto deployment pipeline.
In this article, I show you how to set up Visual Studio Code to get an overview of your tests and debug individual tests.
The main goal of this blog is to explain the “Architecture of Nodejs” and to know how the Nodejs works behind the scenes. Generally, most of the server-side languages, like PHP, ASP.NET, Ruby, and including Nodejs follows multi-threaded architecture. That means for each client-side request initiates a new thread or even a new process.
