tinySQL WASM Browser (wasm_browser)

Compiles tinySQL to WebAssembly and serves it with a modern browser UI. The entire SQL engine runs client-side — no server required after the initial file download.

Build

All-in-one script

cd cmd/wasm_browser

# Build only (produces web/tinySQL.wasm + web/wasm_exec.js)
./build.sh --build-only

# Build and start a local HTTP server on port 8080
./build.sh --serve

Then open http://localhost:8080 in your browser.

Manual build

cd cmd/wasm_browser
GOOS=js GOARCH=wasm go build -o web/tinySQL.wasm .
cp "$(go env GOROOT)/lib/wasm/wasm_exec.js" web/
cd web && python3 -m http.server 8080

UI features

• SQL editor with multi-statement support
• Result table with column headers
• Schema inspector (list tables, show columns)
• Query history stored in localStorage
• Export results as CSV or JSON

JavaScript API

The WASM module exposes global functions callable from the browser console or your own JavaScript:

Notes

• The database is in-memory and resets on page reload.
• WASM files must be served over HTTP (not file://) due to browser security restrictions — use the built-in server or any static file host.
• For a Node.js variant see ../wasm_node/.
