i'm deliberately throwing together a number of new technologies for me; this is developed in svelte and typescript (just javascript with extra syntax for type declarations), and managed and run with bun.
i'm using bun, but npm works just as well, i think; just sub npm for bun in the following lines.
install bun:
brew tap oven-sh/bun
brew install buninstall dependencies:
bun installrun:
bun run dev
