1# Frontend
2
3This template is a classic client-side-only React app.
4
5## `index.html`
9This HTML file imports `/frontend/style.css` from `/public/style.css` and `/frontend/favicon.svg` from `/frontend/favicon.svg`. Everything in `/frontend/` is mapped to `/public` by `/backend/index.ts`. This is just a convention. You could import & serve everything out of the same folder name.
10
11This HTML file has a `<div id="root"></div>`, which is where we mount the React app.
12
13This HTML file imports `/frontend/index.tsx` from `/public/index.tsx`, which is the **entrypoint** for all frontend JavaScript, including all the React. It is not a problem that it imports a file with a `.tsx` extension becaues browsers ignore file extensions. They only pay attention to content-types, which is great, because all these files will be returned as transpiled JS with the appropriate JS content type by [stevekrouse/utils/serve-public](https://www.val.town/x/stevekrouse/utils/branch/main/code/serve-public/README.md).)
14
15## `index.tsx`
16
17This file is the **entrypoint** for frontend JavaScript. It imports the React app from `/frontend/components/App.tsx` and mounts it on `<div id="root"></div>`.
18
19It also looks for *bootstrapped* JSON data at `window.__INITIAL_DATA`, and passes that only to the `<App />`.
25## `components/`
26
27This directory is where the React components are stored. They're pretty standard client-side React components.
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`. These routes are called from the React app to refresh and update data.

30## Errors
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.
