tsx
Advanced tools
Package description
The tsx npm package is a CLI tool for running TypeScript and TSX files directly without pre-compilation. It's essentially a TypeScript execution and REPL for node.js, similar to how `node` works for JavaScript. It allows developers to quickly run scripts and prototypes written in TypeScript, including support for TSX (TypeScript with JSX syntax), which is commonly used in React development.
Execute TypeScript files directly
Allows you to run a TypeScript file directly from the command line without needing to compile it first. This is particularly useful for quick scripts or during development.
tsx script.tsREPL mode
Launches a REPL (Read-Eval-Print Loop) where you can type and execute TypeScript code interactively. This is useful for testing small snippets of code quickly.
tsxSupport for TSX
Enables execution of TSX files, which is TypeScript with JSX syntax. This is particularly useful for React developers who want to test components or scripts that include JSX.
tsx component.tsxts-node is a very popular package that offers similar functionality to tsx. It provides the ability to execute TypeScript files directly and use TypeScript in a REPL environment. ts-node is widely used in the TypeScript community for development and scripting. Compared to tsx, ts-node has been around longer and has a larger user base, but both aim to simplify the TypeScript development workflow by removing the compilation step.
esbuild-runner offers a way to run TypeScript (and JavaScript) files using the esbuild bundler/compiler. It's focused on providing extremely fast compilation and execution, leveraging esbuild's performance. While esbuild-runner and tsx share the goal of simplifying the execution of TypeScript files, esbuild-runner emphasizes speed and is part of the broader ecosystem around the esbuild project.
Readme
Node.js runtime that can instantaneously load TypeScript & ESM, powered by esbuild.

Install it globally to use it anywhere, outside of your npm project, without npx.
npm install --global tsx
Note: Commands are prefixed with
npxto execute thetsxbinary, but it's not necessary if globally installed or when using it in thescriptobject inpackage.json
npx tsx ./file.ts
Run file and automatically re-run on changes.
All imported files are watched except from the following directories:
node_modules, bower_components, vendor, dist, and .* (hidden directories).
Press Return to manually re-run.
npx tsx watch ./file.ts
Modules transformations are cached in the system cache directory (TMPDIR). Transforms are cached by content hash so duplicate dependencies are not re-transformed.
Set the --no-cache flag to disable the cache:
npx tsx --no-cache ./file.ts

@esbuild-kit/cjs-loader - TypeScript & ESM to CJS transpiler using the Node.js loader API.
