Hey Zizaco, great to have you here. Pointer Lock isn’t implemented yet, but it’s on my to-do list 🙂 it’ll be included in the next update.

Thank you for your feature request. They are included in the new Update of GemShell: https://l0om.itch.io/gemshell/devlog/1137312/gemshell-v060-changelog

New big major Update is here!

https://l0om.itch.io/gemshell/devlog/1131890/beta-051-steamworks-native-apis-are...

This will be possible in the next update fyi :-):


const ws = new WebSocket('wss://server.com/game');

ws.onopen = () => console.log('Connected');

ws.onmessage = (e) => console.log('Data:', e.data);

ws.onerror = (e) => console.error('Error:', e);

ws.onclose = () => console.log('Disconnected');

ws.send(JSON.stringify({ action: 'move', x: 10, y: 20 }));

Hello Bioburden,

It's great to have you here! Our vision is to pack small games that include everything we need. While there are many frameworks available with Chromium and Node.js, we see this as an opportunity to develop our own native server communication API without unnecessary bloat. I'll note this as a feature request for upcoming updates.

The new version will not include Neutralino anymore, and Chromium is not currently planned. However, I will take it as a feature request because GemShells' vision is to deliver executables as small as possible.

The new update will include native Steamworks with all essential functions, allowing you to use the GemShells API to interact with Steam. It currently works properly on Mac and Windows, while Linux is still in testing.

Hey, nice to have you here!

Quick note on Steam support: it’s not available yet because we don’t bundle Node.js with your game. I’m adding Steamworks via native C bindings so you’ll get the key features without Node.js bloat soon.

I can’t give an exact ETA, as I’m heads‑down on a major GemShell update right now. I’ll share progress and timelines as soon as they’re ready.

Thanks for the feedback, great to hear it works with ExcaliburJS! Stay tuned for the next big update, it will significantly improve performance across all operating systems and deepen our Steamworks integration.

Welcome! Super excited to hear any feedback or feature requests – join us in our Discord channel! Big love to jslegend!

Now you can see GemShell in JSLegendDev's Youtube Video!

Hey, nice to see you here. You can easily pack a normal html into an exe :-) just try it out!
