txiki.js is a small and powerful JavaScript runtime. It targets the latest ECMAScript spec and implements many web platform features.

It’s built on the shoulders of giants: it uses QuickJS-ng as its JavaScript engine, libuv as the platform layer, wasm3 as the WebAssembly engine and curl as the HTTP / WebSocket client.

Earlier this week I released version 24.12.0 featuring standalone executables, namespace reorganization, more web platform features, initial binary releases, more filesystem APIs, REPL updates and more! Check here for the full changelog, and read-on for some highlights.

txiki.js is a small and powerful JavaScript runtime. It targets ECMAScript 2020 and implements many web platform features.

It’s built on the shoulders of giants: it uses QuickJS as its JavaScript engine, libuv as the platform layer, wasm3 as the WebAssembly engine and curl as the HTTP / WebSocket client.

After a few months of hiatus I’m happy to announce a new txiki.js release: 23.10.0, and it’s a good one!

This new release is packed with new features:

• Faster startup time
• New fs features
• SQLite builtin module
• Storage web APIs support
• curl integration fixes
• Added import.meta.path
• Better CLI errors
• Improved types documentation

Check the full changelog here!

This release is particularly exciting because I’ve been looking forward to integrating SQLite support for a while. I started implementing the Storage API support thinking I’d use a file for persistence, but at one point I thought I’d use a SQLite databse instead, so I went for it!

There is likely stuff to be improved specially in this new builtin, the SQLite module, but I’m happy it’s in now!

The last release was over 6 months ago, so please do check the full changelog, I almost didn’t remember all the things that were added in the months past…

Thinking ahead, it might be time to start bringing in Mbed TLS support. Maybe just hasing at first, then TLS sockets, then WebCrypto. Step by step…

After a few months of more work I’m happy to announce a new txiki.js release, version 23.1.0, quite possibly the biggest release I’ve made, and one that paves the way for the future. Let’s dive right in!

Standard library refactor

I’ve actually gone back and forth on this one. The standard library modules started being importable as @tjs/ modules, but I later switched to having it all bundled together in @tjs/stdlib. While easier to work with, that was a mistake. It’s slower to load and the churn due to the bundles being in the repo is just annoying.

It’s also important to look around and see what others are doing. Both Node and Bun seem to have settled in using namespace:module naming for builtins, so that’s what I went with. All standard library modules are now imported like so: tjs:module.

These modules are now documented too, so you can see the full API at a glance.

CLI refactor

The CLI also got some much needed love on this one. Generally speaking the CLI allowed one to either launch a file or eval an expression, plus some modifiers for each. After giving it some though, the idea of using subcommands sounded the most appealing, so now you can do tjs run foo.js and tjs eval ”console.log(42)”

But there is more. There is a also a builtin test runner now so tjs test is a thing too!

Last, running WASI binaries directly was too easy not to do, so you can also tjs run foo.wasm now and it works as expected.

Top level await

Just when I was about ready to cut the release I noticed zamfofex had sent a patch adding top level await support to QuickJS to the mailing list. That was too good to pass so I quickly incorporated it, and it worked beautifully!

This makes writing simple scripts (and tests!) so much more pleasant! So off I went and migrated the test suite to use TLA, the examples too, and added some initial support to the REPL while I was at it!

There is even more!

While these are the highlights, there are a lot more fixes that went into the release. Please checkout the full release notes here.

Today I’m happy to release txiki.js 22.11, which contains a bunch of improvements that have happened during the last few months. Let’s look at some of those!
