Combining TypeScript and React to Build Robust & Scalable Web Apps

Introduction

React is a front-end JavaScript library used in web app development services for making interactive ui with fewer efforts because react is a component based library that allows users to use the DRY(don’t repeat yourself ) principle of coding with its advantage of defining components once and calling them anywhere in your code.

Many top web app development companies prefer to use MERN stack development given the benefits of React.js. Of course, it depends on the nature of software development project complexities and custom business needs. React is fast because it uses virtual dom which is lighter than real dom and doesn’t directly update the complete DOM if any data updates instead update only the changed UI part, which enhances the overall user experience.

Today, React is one of the most popular front-end libraries, used by thousands of companies and developers worldwide. Its simplicity and versatility have made it a go-to choice for many web and mobile development projects. It has a direct hand in increased demand for hiring React.js developers too.

When adding TypeScript to react projects it improves the developer’s experience with its capabilities of type checking and reporting errors while writing the code if the type mismatches or not getting the expected datatype.

History of React.js

React is developed and maintained by Facebook and since when it was released in 2013 its most popular front-end library among web app developers because of its simplicity and scalability.

This amazing open-source JavaScript-based front-end library was created by Jordan Walke, a software engineer at Meta, who was inspired by XHP (HTML Component Library) Project. He started working on React in 2011, and it was first used in Facebook’s News Feed in 2012.

Meta released React In 2013 as an open-source project. It quickly gained traction among developers and was adopted by many companies, including Netflix, Airbnb, and Dropbox.

Why to Use React?

1. React is a component based front-end library that helps in managing substantial web applications and improves the readability of code.

2. Debugging is easy and fast because of the chrome extension provided by Meta.

3. It is easy to get started and learn with just some basic knowledge of HTML, CSS, and JavaScript.

4. A large number of people use react so, a Strong community backs reactjs which makes it easy for newbies to search their errors and find an immaculate solution also its GitHub Repository has over 202K stars which make it one of the top github repositories.

5. React can provide Compile time errors with the use of JSX. It also prevents XSS (cross-site-scripting) attacks popularly known as injection attacks because everything is converted to a string prior to rendering.

What are the Latest Features in React?

1. Concurrency

Concurrency in React refers to how multiple updates to a React component or application are managed and executed by the React framework. In React, updates are processed as a queue and executed in a specific order to ensure that components are updated consistently and correctly With concurrency, we can choose what to render and what to pause for example if we are fetching users list and then if we go to another component and filter product according to some criteria then with concurrency we can pause fetching of user list and start filtering of product.

2. Automatic Batching

Automatic batching is an important part of React’s performance optimization strategy, as it minimizes the number of render operations, reduces the amount of work that needs to be done, and ensures that updates are executed consistently and correct if multiple updates are triggered at the same time, React will group them together into a single batch and execute them in the order in which they were triggered.

3. Transition

When we want to make something low in priority to improve the performance of ui and enhance the overall user experience we should use transition with this react wisely render components.

4. useId hook

This is a hook in react used for generating unique id in both client and server side and like other hooks in react it should also define at the top level and never inside some conditions or loops. useId hooks should not used to provide keys for list, below is an example for useId hook where input type file is used and selecting image by clicking on an icon.

What is TypeScript?

TypeScript is not loosely typed like JavaScript but a strongly typed language that builds on top of JavaScript. It was developed and is maintained by Microsoft, and has become increasingly popular in recent years as a type-safe alternative to JavaScript.

Key Benefits of Using TypeScript Include

1. Type safety

TypeScript provides type annotations and interfaces to help catch type-related errors early in the development process before they become runtime errors, here is an example of interface of person where firstName and lastName is string and must be passed while calling the function but age is type of number and it’s optional.

2. Improved maintainability

By catching type-related errors early and making the type information more explicit, TypeScript makes it easier to write maintainable code.

3. Better tooling

TypeScript has better tooling and editor support than JavaScript, which can help improve productivity and make it easier to write, test, and debug code.

4. Interoperability with JavaScript

TypeScript is designed to be fully compatible with JavaScript, meaning that existing JavaScript code can be easily migrated to TypeScript and that TypeScript code can be easily integrated into existing JavaScript projects.

5. Future-proofing

TypeScript adds features and syntax that are expected to be part of the future versions of JavaScript, making it easier to write code that will continue to work as the language evolves.

Benefits of using React With TypeScript

1. Improved code quality

TypeScript provides static typing, which helps to catch errors earlier in the development process, making it easier to maintain and scale the codebase.

2. Better documentation

TypeScript provides better documentation by enforcing type annotations, making it easier for other developers to understand the code.

3. Better code writing

TypeScript integrates well with modern development tools, including IDEs and code editors, providing improved autocompletion, error detection, and refactoring capabilities.

4. Improved performance

TypeScript can help improve performance by catching errors before runtime and reducing the need for tests.

5. Increased developer productivity

TypeScript provides a more robust and flexible development environment, which can help increase developer productivity and reduce the time and effort required to build and maintain applications.
