-> [!IMPORTANT]
-> TypeScript modules are built and published with the `spacetime` CLI. `spacetime publish` will transpile and bundle your server module for you starting with the `src/index.ts` entrypoint. If you bundle your js yourself, you can specify `spacetime publish --js-path <path-to-your-bundle-file>` when publishing.

-
-```bash
-cd quickstart-chat
-spacetime publish --project-path spacetimedb quickstart-chat
