Developers and teams building JavaScript and TypeScript applications who want a fast, all-in-one runtime and toolkit to run, test, bundle, and manage packages with high performance and Node.js compatibility

About Bun

Bun is a fast, all-in-one JavaScript, TypeScript, and JSX toolkit that ships as a single executable and combines a high-performance runtime, package manager, test runner, and bundler designed as a drop-in replacement for Node.js with broad compatibility and dramatically reduced startup times and memory usage. Written in Zig and powered by Apple’s JavaScriptCore, Bun can execute JavaScript/TypeScript files, scripts, and packages with significantly faster performance than traditional tooling while supporting zero-config TypeScript, JSX, and React out of the box. Its built-in package manager installs dependencies up to 30× faster than npm with workspaces, global caching, migration support, and dependency auditing. Bun’s test runner is Jest-compatible with built-in coverage and concurrent execution, and the bundler processes TypeScript, JSX, CSS, and more without configuration, including support for single-file executables.xx

TypeScript
TypeScript
TypeScript adds additional syntax to JavaScript to support a tighter integration with your editor. Catch errors early in your editor. TypeScript code converts to JavaScript, which runs anywhere JavaScript runs: In a browser, on Node.js or Deno and in your apps. TypeScript understands JavaScript and uses type inference to give you great tooling without additional code. TypeScript was used by 78% of the 2020 State of JS respondents, with 93% saying they would use it again. The most common kinds of errors that programmers write can be described as type errors: a certain kind of value was used where a different kind of value was expected. This could be due to simple typos, a failure to understand the API surface of a library, incorrect assumptions about runtime behavior, or other errors.
