TypeScript is widely adopted and well-supported in various popular JavaScript frameworks and libraries, enhancing the development experience by providing strong typing, code analysis, and improved tooling. Here are some of the major JavaScript frameworks and libraries that have official TypeScript support:

Angular:

• TypeScript is the primary language for Angular development. The Angular team at Google actively promotes and uses TypeScript for building scalable, maintainable web applications.

React:

• While React itself is written in plain JavaScript, many React developers use TypeScript to take advantage of strong typing. TypeScript can be easily integrated into React projects, and tools like create-react-app support TypeScript templates.

Vue.js:

• Vue.js officially supports TypeScript, and developers can create Vue applications using TypeScript as the programming language. This combination offers type safety while maintaining Vue's simplicity.

Ember.js:

• Ember.js, a full-featured web framework, provides strong TypeScript support. It has well-documented TypeScript integration and a set of type definition files to assist developers.

Express.js:

• Express is a popular Node.js web framework. TypeScript can be used to write Express applications, offering type checking and improved code quality. The @types/express package provides type definitions for Express.

NestJS:

• NestJS, a backend framework for Node.js, is written in TypeScript and encourages developers to use TypeScript when building APIs. It leverages decorators and TypeScript features for building scalable applications.

Next.js:

• Next.js, a popular framework for building React applications, can be configured to use TypeScript for server-side and client-side code. This enhances type safety and error checking in Next.js projects.

Gatsby:

• Gatsby, a static site generator for React, supports TypeScript for both building and extending the framework. Developers can use TypeScript to write plugins and themes for Gatsby.

Svelte:

• Svelte is a component-based JavaScript framework. While it's often associated with JavaScript, TypeScript can be used with Svelte for stronger type checking and better tooling support.

Redux:

• Redux, a state management library for JavaScript applications, has type definition files available for TypeScript. Using TypeScript with Redux improves type safety when managing application state.

Apollo Client:

• Apollo Client, a popular GraphQL client, offers TypeScript support. Developers can use TypeScript to define GraphQL queries, mutations, and type-safe components.

RxJS:

• RxJS, a library for reactive programming, is commonly used with TypeScript. Type definitions for RxJS are available, providing type safety when working with observables.

Three.js:

• Three.js, a popular 3D graphics library for the web, supports TypeScript. TypeScript can be used to write WebGL-based applications with type checking.

Jest:

• Jest, a testing framework often used in JavaScript projects, has TypeScript support. Developers can write type-safe test suites and unit tests using TypeScript.

These are just a few examples of popular JavaScript frameworks and libraries that have official TypeScript support or can be effectively integrated with TypeScript. The combination of these frameworks with TypeScript provides the benefits of strong typing, improved tooling, and enhanced code quality for web and application development.
