+Unfinished Automerge websocket server for Vite (Svelte, SvelteKit, etc)
+
+How to get started:
+
+In vite.config.ts, add the following:
+
+```
+import { websocket } from "@automerge/automerge-repo-svelte-sync-server/webSocketUtils"
+import wasm from "vite-plugin-wasm"
+
+export default defineConfig({
+  plugins: [..., wasm(), websocket()],
+
+  worker: {
+    plugins: [wasm()]
+  },
+
+  optimizeDeps: {
+    // This is necessary because otherwise `vite dev` includes two separate
+    // versions of the JS wrapper. This causes problems because the JS wrapper
+    // has a module level variable to track JS side heap allocations, and
+    // initializing this twice causes horrible breakage.
+    exclude: [
+      "@automerge/automerge-wasm",
+      "@automerge/automerge-wasm/bundler/bindgen_bg.wasm",
+      "@syntect/wasm"
+    ]
+  }
+})
+
+```
+
