I'm excited to share my latest pet project with you!

I wanted to experiment with Compose for Web and take advantage of Ktor's new WASM support, so I built a seed browser for my favorite game Oxygen Not Included. 😊

Both the frontend and backend are entirely written in Kotlin, and the project is licensed under AGPL3.

Check it out on https://stefan-oltmann.de/oni-seed-browser

Looks great! Did you have any specific learnings or challenges? Apart from the SVG saga? 😉

[Stefan Oltmann]

Thank you! 😊

No major challenges with the tech—it’s working quite well already.

One new experience for me was drawing on a canvas, something I hadn’t done before. Since I’m not great with math, I relied on ChatGPT to help me draw the hexagon map. 😄

At the backend I used MongoDB, which looks great at first, but I quickly realized that slightly more complex queries require a ton of statements that make no sense to me. Even with the help of ChatGPT I wasn't able to implement the geyser count filter. Also, the Mongo Compass AI keeps generating invalid queries. This was my first time trying MongoDB and I think I don't like it.

This looks fantastic! Also ONI is a wonderful game!

It says Safari is not supported 😞

[Stefan Oltmann]

Yes, that's on Apple, unfortunately. They are the last to proper support WebAssembly.

Great project I have questions if possible the loading page is a little bit faster like any website open very fast loaded in wasm is take time 4-5 second loaded page

[Stefan Oltmann]

Thanks. Yes, the WASM file takes a bit to load. It's also about 15 MB in size with 8 MB for skiko alone. It takes 2 seconds on my device uncached. No idea how to make that faster.

yes that why i am not building my website in wasm it take time to load page so user gone website

[Stefan Oltmann]

I build my web projects in WASM because I love Kotlin and hate JavaScript. 🙂

[Stefan Oltmann]

If the user want to find good game seeds for ONI they'll have to wait for WASM to be loaded. 😉

[Meet]

yes, you are right i also love kotlin but i not talking about game like portfolio, service website so it take faster loaded page

[Stefan Oltmann]

This site is slower, because it also uses Compose for Web which requires skiko.

https://stefan-oltmann.de/exif-viewer is also a WASM project, but renders HTML. This should load way faster.

[Stefan Oltmann]

For a portfolio website I would just make something static, to be honest.
GitHub Pages with Jekyll or something like that.

i love kotlin so i deside to portfolio website in kotlin. but i dont know how can do responsive website in kotlin

[Stefan Oltmann]

Choose the right tool for the job.
