The `additional-modules` plugin rewrites `import 'foo.wasm'` (and .bin, .txt, .html, .sql) to a virtual `__CLOUDFLARE_MODULE__CompiledWasm__/<abs> __CLOUDFLARE_MODULE__` URL so the bundler can inline the file's content as an asset at build time. In dev (no `renderChunk`), Vite's Node-side SSR module runner still resolves that virtual ID and then tries to load it. The 'file' portion is just a marker — vite's `transformRequest` runs, finds no real file on disk, and throws `Failed to load url __CLOUDFLARE_MODULE__...`. Fix: add a `load` hook that matches the virtual id, reads the .on-disk .wasm / .bin / .txt file here in the plugin (Vite Node main process), and inlines the bytes as a base64 string literal in the returned module source. Why base64: Vite evaluates the returned source inside `new AsyncFunction(...)`, where top-level `import` statements are illegal. The returned source has no imports — it builds the buffer from the inlined string with `Buffer.from(__b64, 'base64')`. Why CompiledWasm / Text / Data each get their own branch: `CompiledWasm` and `Data` should produce binary buffers; `Text` is utf-8 text. Each branch emits a default export of the correct shape for its consumer.
