Dev log #2

Log entry: I’ve been working over the past few days on SSR performance and sorting out the DX side.

I reduced the initial size of the payload and altered the way components hydrate, which as a result decreased response latency on the native Bun HTTP server. I refactored the startup CLI and improved hot module reloading, file changes now appear instantly rather than sometimes needing a restart.

A routing bug involving the parsing of query parameters which was causing problems with the serving of static assets in certain situations has also been fixed, and the way in which internal state is managed throughout the request lifecycle has been cleaned up.

What was annoying was the situation with concurrent requests when doing hot reloads since Bun would leave the state hanging between reloads, a problem that only became apparent under heavy load. It took some time to work out what was going on and in the end I added more detailed logging to detect the cases where the memory wasn’t being freed. The server now runs cleanly without the need for manual restarts, which was the real aim.
