//go:build js && wasm

// Package main provides the WASM entry point for the WasmDB database.
// It initializes the IndexedDB-backed Nostr event store and exposes
// the database API to JavaScript via the global `wasmdb` object.
//
// Build with:
//   GOOS=js GOARCH=wasm go build -o wasmdb.wasm ./cmd/wasmdb
//
// Usage in JavaScript:
//   // Load wasm_exec.js first (Go WASM runtime)
//   const go = new Go();
//   const result = await WebAssembly.instantiateStreaming(fetch('wasmdb.wasm'), go.importObject);
//   go.run(result.instance);
//
//   // Wait for ready
//   while (!wasmdb.isReady()) {
//     await new Promise(resolve => setTimeout(resolve, 100));
//   }
//
//   // Use the API
//   await wasmdb.saveEvent(JSON.stringify(event));
//   const events = await wasmdb.queryEvents(JSON.stringify({kinds: [1], limit: 10}));
