Post

Last week, for some reason, I was working on, let’s say, a Postman/Insomnia tool, but very specific to us. It is quite interesting how to make it fast- for instance, a simple json/xml response view to render 10MIB of payload.

This thread is going to be a list of random topics from that project.

First attempt was Tauri and React with Base UI. In general, it worked. Quite fast; however, on our data, it was very slow. Extracting some logic to Rust and passing a lot of data via IPC not a good idea.

Then I decided to rewrite early using GPUI and GPUI-Components. And now we have a single codebase on desktop and on server. In our case, the server can be local, bundled with the app, or remote- no matter.

Cold start is full bounce- jump and land.
