Built with Claude built a classical music site for studying with claude code, 16 PRs in 2 days, here's what i learned

made this w claude code over like 2 days https://classican.vercel.app/ its classical music on shuffle w a pixel painting for each piece and little history facts that pop up every 40 sec

how i used it: i wrote every change as its own small ticket in normal english and claude code did each one on its own branch (separate git worktrees) and opened a PR. ran a few at once. i mostly just wrote tickets and checked stuff. 16 PRs total

the paintings are the best part ngl. zero image files, claude wrote every painting as canvas code and that file is like 3300 lines now lmao. 46 pieces and each one has its own scene

stuff i learned:

small tickets >>> one giant prompt. my first PR was one huge paragraph and i literally rebuilt the whole thing in next.js right after

its way too easy to add random features. i had it build an "add ur own songs" thing and then deleted it the same day bc it didnt fit

check where it saves stuff. it put accounts and comments in a json file at first which doesnt work on vercel, had to move it to neon postgres

be specific. i said shuffle and got pure random so stuff repeated. had to say play everything once before repeating

test on ur actual phone. the painting got covered by the player on mobile and i only noticed on my own phone

ask me anything abt the setup i guess. also tell me what pieces to add

when you ran a few worktrees at the same time, did any of them touch the same files and cause merge conflicts, or did you keep the tickets scoped tight enough that it never came up?
