In this article, we’ll learn how to handle node & express in Typescript.
Node.js is an open-source, cross-platform run-time environment used for developing fast and scalable real-time applications with a persistent connection between the user’s browser and server. It executes server-side JavaScript code.
Express.js is simply a web application framework of Node.js. It helps in developing node-based web applications rapidly. Let’s see some of the core features of Ethe xpress framework,
TypeScript is a language for application-scale Javascript and can be considered as a superset of JavaScript. It adds optional types to Javascript that support large scale JS applications, on any browser and OS. It can be thought of as JavaScript with additional features such as strong static typing, compilation and object-oriented programming etc.
Steps to follow.
Let’s start the setup for TypeScript with Node and Express.
Step 1 -_ Folder creation and Depen_****dency Installation
Create a new folder for our project (after Node and Npm installation):
Nodets_express
Install the dependencies using NPM
npm install typescript
tsc –init
Step 2** - Configuring TypeScript**
“target”: “es5” -> “target”: “es6”,
“outDir”: “./build”,
“rootDir”: “./src”,
“moduleResolution”: “node”,
Note The tsconfig.json file is located at the root directory of any TypeScript project. The tsconfig.json file has the details of the root files and the compiler options required to compile the project.
Step 3
Initialize it as an Npm project
npm init --y
Step 4
To install the _Express _framework, use the below commands.
npm install express
npm i -D typescript ts-node nodemon @types/node @types/express
Step **5 - **Setting Up The Folder Structure
To start with the TS application, create a folder structure as below:
src/app.ts
_ src_ folder - In the root of our project directory.
app.ts file - Inside src folder.
In the terminal, execute the below command:
cd src
touch app.ts
At this point, we should have a folder structure that looks like this,
Now, go to the localhost in the browser. The below result appears which indicates successful execution.

Today we are going to look at how we can use Express EJS Layouts to help us with website templating which ultimately help us to avoid writing duplicated code as well as making our website/application easily maintainable.
I had to cut off the intro as the music was too lound.

Hello, my friends and fellow developers, in this video, I have talked about setting up TypeScript and NodeJS with Express.

Learn how to set up TypeScript in an Express.js app. This post describes a beginner-friendly way to set up TypeScript in an Express.js app and understand the basic constraints that come with it.
Ease of development is great when you are building a server written in JavaScript using Node.js and Express. What happens when this application server scales or you are working in a team of developers all across the world? TypeScript can help.
In this post, I am not going to talk about whether you should use TypeScript or not. This post describes a beginner-friendly way to set up TypeScript in an Express.js app and understand the basic constraints that come with it.
To take full advantage of this tutorial, please make sure you have the following installed in your local development environment:
12.x.x
installednpm
or yarn
Start by creating a new directory where you keep your side projects in your local development environment. Inside that directory, use npm’s initializer command to create a package.json
file:
media server
cd server/
npm init --yes
The --yes
flag uses the default settings when initializing a package.json
from npm
config you might have set up.
The package.json
file created might look something like this:
{
"name": "express-ts-example",
"version": "0.0.1",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "Aman Mittal (https://amanhimself.dev)",
"license": "MIT"
}
After the initializing step, let us add an express
package. From the terminal window, run the command:
yarn add express@4.17.1
Next, create a new file called index.js
at the root of the project with the following code to trigger a minimal server:
const express = require('express');
const app = express();
const PORT = 8000;
app.get('/', (req,res) => res.send('Express + TypeScript Server'));
app.listen(PORT, () => {
console.log(`⚡️[server]: Server is running at https://localhost:${PORT}`);
});
Go back to the terminal and trigger the common node index.js
to start the server.
The Express server is now up and running.
Let’s add two libraries to the development server as devDependencies
.
typescript
is a core library that helps to compile the TypeScript code to valid JavaScriptts-node
is a utility library that helps to run a development server written using TypeScript directly from the terminalTo install them, from a terminal window run the following command:
yarn add -D typescript ts-node
The -D
flag is also known as --dev
flag and is a specification for the package manager to install these libraries as devDependencies
.
Once these libraries are installed, go to the package.json
file and see a new devDependencies
object:
"devDependencies": {
"ts-node": "8.10.2",
"typescript": "3.9.5"
}
Next, create a tsconfig.json
file at the root of the development server project. This file allows you to customize TypeScript configuration and add other configurations to compile the TypeScript project:
{
"compilerOptions": {
"target": "es6",
"module": "commonjs",
"rootDir": "./",
"outDir": "./build",
"esModuleInterop": true,
"strict": true
}
}
The compilerOptions
is a mandatory field that needs to be specified. The options used in the config above are:
target
allows us to specify the target JavaScript version that compiler will outputmodule
allows us to use a module manager in the compiled JavaScript code. The commonjs
is supported and is a standard in Node.jsrootDir
is an option that specifies where the TypeScript files are located inside the Node.js projectoutDir
specifies where the output of the compiled is going to be locatedesModuleInterop
allows us to compile ES6 modules to commonjs
modulesstrict
is an option that enables strict type-checking optionsThere might be other configuration options that you can add on for the TypeScript compiler but these are the basic configuration options specified that can help you to get started.
