Getting Started

txikia (Basque): small, tiny.

txiki.js is a small and powerful JavaScript runtime. It targets state-of-the-art ECMAScript and aims to be WinterTC compliant.

It's built on the shoulders of giants: it uses QuickJS-ng as its JavaScript engine and libuv as the platform layer.

Installation

Prebuilt binaries are available for macOS and Windows from the GitHub Releases page:

Platform	Architecture
macOS	arm64, x86_64
Windows	x86_64

Download the zip for your platform, extract it, and add the tjs binary to your PATH.

On Linux (and other Unixes), you'll need to build from source.

Try it out:

./build/tjs eval "console.log('hello world')"

Run a script with tjs run:

./build/tjs run examples/hello_world.js

Explore all the options:

./build/tjs --help

txiki.js comes with a rich set of features out of the box:

Web Platform APIs — fetch, WebSocket, Console, setTimeout, Crypto, Web Workers, and more
Runtime Features — TCP/UDP sockets, file I/O, child processes, signal handling, DNS
Standard Library — tjs:sqlite, tjs:ffi, tjs:path, tjs:hashing, and more
HTTP Server — high-performance HTTP server with WebSocket support
Standalone Executables — compile your scripts into self-contained binaries
