SQL executes on the client, with no backend. This repo is just the web page + its Vercel deploy . The engine itself (the WebAssembly build, the glue JS, and the .wasm ) lives in the chdb-wasm npm package (built from chdb-io/chdb-core ); this shell only consumes it. Layout - web/index.html — the shell. It references ./dist/... ; the build rewrites ./dist to a content-hashed ./dist- / directory so the engine can be cached forever. - vercel.json — deploy config: COOP/COEP cross-origin-isolation headers (needed by the multi-threaded build), immutable caching for the hashed engine dir, no-cache for the page, plus the build command and output directory. - scripts/build-vercel.sh — assembles the deploy output ( out/ ) from the installed chdb-wasm engine + web/ , content-hashing the engine dir. - scripts/serve.mjs — local preview server (sets COOP/COEP). Local preview index.html loads the engine from ./dist ; the preview server maps /dist/ to the installed chdb-wasm package. To preview an unpublished local build instead, symlink it: Deploy (Vercel) Hosted on Vercel as a static site — no backend. Everything, including the 100 MB .wasm , is served as a same-origin static asset straight from Vercel's CDN; Vercel has no per-file size limit, so there is no external object store or streaming function (unlike the old Cloudflare Pages + R2 setup).
