I've recently taken a legacy Typescript clientside codebase that was using webpack to generate tens of js packages from minutes to seconds by using bun [0] for both dev and build: For dev I replaced webpack with "bun vite": it loads scripts ad hoc and is thus super fast at startup, and it still supports hot reloading. For build I use "bun build". I've created a small script where I don't specify the output folder, but just intercept it, and do some simple search & replace things. It works perfectly, although it's a bit of a hack (simplified code): const result = await Bun.build({ entrypoints: [srcName], root: "./", minify: true, naming: `${configuratorName}.[hash].[ext]`, }); for (const r of result.outputs) { let jsSource = await r.text() jsSource = jsSource.replaceAll("import.meta.hot","false") Bun.write(outdir + r.path.substring(1), jsSource); } It might not be pretty, but it works super fast, and it only took me a couple of hours to convert the whole thing... Update: For the record, the real script also uses the HtmlRewriter from cloudflare (included by default in bun) to alter some basic things in HTML templates as well...
