TypeScript is a scripting language that understands JavaScript and uses type inference to provide advanced functionality without the need for additional code, and Express js is written in javascript. Even if you have no prior programming knowledge, javascript is a straightforward language to master. It enables a large number of fresh web developers to enter the sector.

What Is NodeJS?

  • Node.js is an open-source, cross-platform JavaScript runtime environment
  • It runs on a web application outside the client's browser
  • The developers use it to build server-side web applications
  • Node js is perfect for data-intensive applications since it uses an asynchronous, event-driven model.
  • Typescript supports coding methods, such as static typing and type checking. 
  • It's designed to create complex and high-level applications. 
  • Having Typescript as the primary language for supporting Node.js capabilities would be ideal.

What Is Express JS?

  • Express is a node js framework designed to build API's web applications and cross-platform mobile apps quickly and easily.
  • Express JS is Unopinionated.
  • Express JS makes the node js easy and is used as a server-side scripting language.  

It's a layer built on the top of the Node js that helps manage servers and routes.

What Is TypeScript?

  • TypeScript is an object-oriented programming language, It is a strongly typed superset of JavaScript, and all the code of Typescript complies with JavaScript.
  • It was developed and maintained by Microsoft.
  • Typescript was created for developers to develop large applications. 

Code written in TypeScript is converted to JavaScript, which may be utilized in any environment that supports JavaScript, such as browsers, Node.js, and your own apps.

Setting Up Development Environment

Let's create a setup to run the typescript node and express for that first. We need to install visual studio code 

  • Step 1: Download VS code and install it

Now you have to install node js 

  • Step 2: Open node.js official website and install it 
  • Step 3: After installing, open VS code and enter a command to see the 

version of node JS 

  • Step 4: "node -v" will show the version of your node, and you can see that the node is successfully installed

Now create a new Folder 

Typescript_and_Express_1.

  • Step 5:Click on the terminal and enter the command "npm init -y"
  • Step 6:This will create a JSON file inside your folder  

Typescript_and_Express_2    

After this, we will install typescript dependencies for that. We will write a command

  • Step 7:npm i -D typescript

Typescript_and_Express_3

  • Step 8: Now we will install the npm package "ts - node" which will help the user to run the typescript files directly
  • Step 9: We will also install nodemon, which we use to automatically restart the node application when there is any change. 

So for that, we will write a command that is "npm i ts-node nodemon"

Typescript_and_Express_4.

  • Step 10: After this, we will install Express JS. For that, write a command 

"npm i express"

/Typescript_and_Express_5

Now we will create a ts config JSON file. For that we will write a command

  • Step 11:“npx tsc - - D”

Typescript_and_Express_6

Now we will create a folder src. 

Inside that folder, we will write all our code 

  • Step 12: Create a folder, open the terminal, and enter a command to create a directory
  • "mkdir src"
  • "src" is a folder name 
  • Step 13: The last step is to create a file name app.ts inside the src folder where we will write our code to execute.
