Why Node.js with Typescript? Everything You Need To Know
Node.js is an open-source, cross-platform built on Google Chrome. Node.js applications are written in JavaScript. They can be within the Node.js runtime on OS X, Microsoft Windows, and Linux. Ryan Dahl developed it in 2009. Its latest version is v0.10.36. Node.js came into existence with a change. The developers of JavaScript changed it from something you could only run in the browser to the things that you could run on your machine. It will work as an independent application. Now you can do many things with JavaScript by making websites interactive.
JavaScript has the ability to do things that other languages like Python can do.
Both the browser JavaScript and Node.js run on the V8 JavaScript runtime engine. This engine takes your JavaScript code and changes it into faster machine code. Machine code is low-level code that the computer can run without defining it. Node.js provides a great library of various JavaScript modules. It simplifies the development of web applications using Node.js to a great extent.
Why Typescript With Node.js?
Node.js is the platform that is seeing an inrush of developers from other languages such as Java and C#. JavaScript developers face problems in the asynchronous programming paradigm and the lack of static typing. A new form of Node.js contains async/await. It simplifies working with asynchronous code, but static typing is still difficult for some developers.
TypeScript comes into the frame now-
JavaScript was brought as a language for the client-side. Node.js has marked JavaScript as an appearing server-side technology. As JavaScript code gets messier, making it difficult to maintain and reuse it. It fails to accept the features of Object Orientation, strong type checking, and compile-time error checks. It avoids JavaScript from succeeding at the enterprise level as a server-side technology. The Typescript was created to bridge this gap.
This open-source language is loved and used by almost every best mobile app development company in India as the company is providing the best mobile app development services based on this technology.
It is great fun using modules written in Typescript. You can read and understand the Typescript with ease.
What is TypeScript-
TypeScript is an open-source language that gets continuous development and maintenance by Microsoft. It is similar to JavaScript and has the use of the same syntax and semantics. All of TypeScript’s code gets converted into JavaScript. This offers a faster learning curve for front-end developers coding in JavaScript. TypeScript is closer in syntax to back-end languages like Java and Scala. This helps backend developers to write front-end code faster. TypeScript works with existing JavaScript frameworks and libraries without any difficulty. It has features from ES6 and ES7 that can run in ES5-level JavaScript engines like Node.js. This offers a great advantage of using features from future JavaScript versions in current JavaScript engines. TypeScript has a simple mixture with task runner tools.
Important Features of TypeScript
It is Cross-Platform: TypeScript can run on any platform that JavaScript runs on. You can install the TypeScript compiler on any Operating System like Windows, macOS, and Linux.
Object-Oriented Language: TypeScript offers powerful features like Classes, Interfaces, and Modules. You can write object-oriented code for client-side and server-side development.
The Static Type-checking: TypeScript works on static typing. It is done using type annotations. It provides type checking at compile time. You can remove errors while typing the code without running your script every time.
The DOM Changes: Similar to JavaScript, we can use TypeScript to change the DOM for adding or removing elements.
ES 6 Features: TypeScript contains most features of planned ECMAScript 2015 (ES 6, 7) such as class, interface, Arrow functions, etc.
Conclusion-
You can set up node.js with typescript with ease. The Ts-node runs the output JavaScript through Node.js.
The internet is flooded with node modules. You can install it and learn from it. The above article will help you to understand it better. With the help of this information, you can now create your first application using typescript and node.js. We should keep in mind that typescript is the superset of JavaScript. It provides options for static typing. Typescript is based on object-oriented programming of language. Node.js with typescript is a great combination. If you want to build a mobile app using Node Js and Typescript then you can hire mobile app developer in India or a top mobile app development company India.
