11[React Hono Example](https://www.val.town/x/stevekrouse/reactHonoExample) is a fuller featured example project, with a SQLite database table, queries, client-side CSS and a favicon, and some shared code that runs on both client and server.

30- [ ] add triggers to sidebar
31- [ ] add upload from SQL, CSV and JSON
32- [ ] add ability to connect to a non-val town Turso database 
33- [x] fix wonky sidebar separator height problem (thanks to @stevekrouse)
34- [x] make result tables scrollable

45  }

47  // Now it's time to upload things to database and blob storage
48  // First, add to database, and get the ID
49  const id = await sqlite.execute(
50    `INSERT INTO ${TABLE_NAME} (title, type, time) VALUES ($title, $type, $time)`,

9- [ ] make it one click to branch off like old jp townie demos
10- [ ] opentownie as a pr bot
11- [ ] give it the ability to see its own client-side and server-side logs by building a middleware that shoves them into a SQL light database date and then give it a tool to access them
12- [ ] do a browser use or screenshot thing to give it access to its own visual output
13- [ ] Have it default to creating a new branch off main

236### Database Patterns
237- Run migrations on startup or comment out for performance
238- Change table names when modifying schemas rather than altering
