sciter-js-sdk VS quickjs

How tiny is the output? What is the API? (I couldn't find any documentation. I thought maybe it's in the Help menu in the app itself but all I found was this https://i.imgur.com/6puOMIe.png - On that note, what level of JS is supported? As far as I can tell it uses this https://github.com/c-smile/sciter-js-sdk which is based on Fabrice Bellard's QuickJS ) Is there sound?

JavaScript & Electron Sciter!

Having normal procedural language for build automation is of course useful. That's for those 10% of cases when "standard" build DSL (make,CMake,etc.) simply do not have facilities.

But the rest of 90% tasks should have compact (easily readable) definitions.

I personally found that Premake5 has quite good balance for these tasks.

Premake files are plain .lua files and due to Lua syntax they are easily readable. And if needed you can call from them procedures defined in again Lua.

So typical project (multiplatform) definition looks pretty readable, for example one project from Sciter SDK:

https://github.com/c-smile/sciter-js-sdk/blob/main/premake5....

More details.

That's why in Sciter I've extended JSX with translation meta instruction @:

Note Tauri is full fledged Client/Server with WebView (client) is running in separate process with RPC between UI process and Rust code (Server).

For the comparison:

Standalone Sciter (scapp.exe, https://github.com/c-smile/sciter-js-sdk/tree/main/bin) takes ~8 MB of RAM (with minimal Cairo and GDI backends).

That's 20 times less than even Tauri.

WebView based solutions are not suitable for applets - small portable desktop applications.

scapp.exe ( Standalone sciter engine ) takes 45 Mb showing its default "about" document.

It does support , with limited support but still.

See: https://github.com/c-smile/sciter-js-sdk/tree/main/samples/c...

Sciter also supports immediate mode painting on any element (like in DearIMGUI):

    element.paintBackground = function(gfx) {

It uses service workers to cache static files, by the time it opens up you already free to be offline, try toggle network switch to verify.

It has download link at bottom of the about page ([accdoo.app/about]) which you could then self host it by dropping into any static hosting services.

btw, the Pi feature was by-product from the original App but I won't expand here, if you'd like to learn more, please checkout its two Show HN post (39115559 and 39138957) previously.

Just go with quickjs, I think this is what you are looking for.

QuickJS

I think QuickJS, written in C, is a user-"friendly" starting point for implementing ECMA-262. Documentation QuickJS Javascript Engine.

There is a readme on the project's main page: https://bellard.org/quickjs/

The newsworthy bit here is that the activity seemed to have stalled for year or two and now Fabrice pushed a few fixes and made a new release.

Just to demonstrate GitHub repositories do not necessarily reflect upon a programmers' body of work, Fabrice Bellard has one (1) repository published on GitHub, quickjs. Compare the list of work on Bellard's home page https://bellard.org/.

> I am still confused, it's a JavaScript runtime intended to be deployed to JavaScript/Wasm runtimes?

Seemingly.

> Why does a JavaScript runtime need a JavaScript runtime?

Because if you want to create a Service Worker server for CloudFlare Workers and other JavaScript/Wasm runtimes, that's the only option for doing that AFAIK.

FWIW, this isn't a new idea. For example, Figma uses QuickJS (https://bellard.org/quickjs/) for their plug-in runtime: https://www.figma.com/blog/an-update-on-plugin-security/
