12## Serving assets to the frontend
13
14This backend HTTP server is responsible for serving all static assets to the browser to render the app, including HTML, JavaScript (including all client-side React), CSS, and even the favicon SVG.
15
16In a normal server environment, you would likely use a middleware [like this one](https://hono.dev/docs/getting-started/nodejs#serve-static-files) to serve static files. Some frameworks or deployment platforms automatically make any content inside a `public/` folder public.
26## CRUD API Routes
27
28This app has two CRUD API routes: for reading and inserting into the messages table. They both speak JSON, which is standard. They import their functions from `/backend/database/queries.ts`. This routes are called from the React app to refresh and update data.

8## Migrations
9
10In `backend/database/migrations.ts`, this app creates a new SQLite table `reactHonoStarter_messages` to store messages.
11
12This "migration" runs once on every app startup because it's imported in `index.ts`. You can comment this line out for a slight (30ms) performance improvement on cold starts. It's left in so that users who fork this project will have the migration run correctly.
