What is a TSX file?

A TSX file is a TypeScript (.TS) file written using JSX syntax. It contains code that is most likely part of a single-page or mobile application. TSX files can be opened in any text editor, but are meant to be opened in source code editors.

More Information

JSX, also known as JavaScript XML, is an extension to the JavaScript programming language. Developers use JSX syntax when developing user interfaces and other application components using React, an open source JavaScript library developed and maintained by Facebook.

Developers working in the TypeScript programming language, which is a variant of JavaScript, can use JSX syntax within their development projects. When they do, they save their in-progress JSX-laden code as TSX files, before eventually transforming those files into .JSX (React JavaScript) or .JS (JavaScript) files.

How to open a TSX file

Because TSX files are plain text files, you can open them in any text editor. However, TSX files are meant to be opened and edited in source code editors, such as Microsoft Visual Studio (Windows) or Github Atom (cross-platform). Source code editors provide helpful editing tools and, with the TypeScript package installed, highlight TypeScript and JSX syntax correctly.
