It's broken up into:\n\n* `index.ts` - this is the **entrypoint** for this whole project\n* `database/` - this contains the code for interfacing with the app's SQLite database table\n\n## Hono\n\nThis app uses [Hono](https://hono.dev/) as the API framework. You can think of Hono as a replacement for [ExpressJS](https://expressjs.com/) that works in serverless environments like Val Town or Cloudflare Workers. If you come from Python or Ruby, Hono is also a lot like [Flask](https://github.com/pallets/flask) or [Sinatra](https://github.com/sinatra/sinatra), respectively.\n\n## Serving assets to the frontend\n\nThis 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.\n\nIn 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. \n\nHowever in Val Town you need to handle this yourself, and it can be suprisingly difficult to read and serve files in a Val Town Project. This template uses helper functions from [stevekrouse/utils/serve-public](https://www.val.town/x/stevekrouse/utils/branch/main/code/serve-public/README.md), which handle reading project files in a way that will work across branches and forks, automatically transpiles typescript to javascript, and assigns content-types based on the file's extension.\n\n### `index.html`\n\nThe most complicated part of this backend API is serving index.html. In this app (like most apps) we serve it at the root, ie `GET /`. \n\nWe *bootstrap* `index.html` with some initial data from the server, so that it gets dynamically injected JSON data without having to make another round-trip request to the server to get that data on the frontend. This is a common pattern for client-side rendered apps.\n\n## CRUD API Routes\n\nThis 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.\n\n## Errors\n\nHono and other API frameworks have a habit of swallowing up Errors. We turn off this default behavior by re-throwing errors, because we think most of the time you'll want to see the full stack trace instead of merely \"Internal Server Error\". You can customize how you want errors to appear.",[],[210,96],"44dfd6b2-496c-11f0-b540-76b3cceeab13","database","11bd958d-ac4e-4d9c-aca7-5db5d2c8929e",["D",1749938980859],[239,240,241,242,243],[210,234],{"_36":271,"_13":96,"_63":272,"_65":235,"_67":68,"_69":32,"_70":71,"_38":273,"_17":73,"_74":24,"_75":274,"_77":53,"_78":-5,"_92":275,"_18":276},{"_36":264,"_13":265,"_63":266,"_65":235,"_67":68,"_69":32,"_70":71,"_38":267,"_17":73,"_74":122,"_75":268,"_77":53,"_78":-5,"_92":269,"_18":270},{"_36":257,"_13":258,"_63":259,"_65":235,"_67":68,"_69":32,"_70":71,"_38":260,"_17":73,"_74":122,"_75":261,"_77":53,"_78":-5,"_92":262,"_18":263},{"_36":251,"_13":181,"_63":252,"_65":235,"_67":68,"_69":32,"_70":71,"_38":253,"_17":73,"_74":122,"_75":254,"_77":53,"_78":-5,"_92":255,"_18":256},{"_36":244,"_13":245,"_63":246,"_65":235,"_67":68,"_69":32,"_70":71,"_38":247,"_17":73,"_74":122,"_75":248,"_77":53,"_78":-5,"_92":249,"_18":250},"44dfd46e-496c-11f0-b540-76b3cceeab13","schema.ts","786a387c-2f6e-48fd-83a9-f7e759295b5c",["D",1749938980859],"import { sqliteTable, text, integer } from \"npm:drizzle-orm/sqlite-core\";\n\n// Messages table\nexport const messages = sqliteTable(\"messages\", {\n id: integer(\"id\").primaryKey({ autoIncrement: true }),\n content: text(\"content\").notNull(),\n timestamp: text(\"timestamp\").notNull().default(new Date().toISOString()),\n});\n\n// Type exports\nexport type Message = typeof messages.$inferSelect;",[],[210,234,245],"44dfd2ac-496c-11f0-b540-76b3cceeab13","9f9811c1-a27d-40ec-bde7-cfd7d002290c",["D",1749938980859],"import { desc } from \"npm:drizzle-orm\";\nimport { db, schema } from \"./db.ts\";\nimport { createTables } from \"./migrations.ts\";\nimport { MESSAGE_LIMIT } from \"../../shared/utils.ts\";\n\n// This will create the database table if it doesn't exist.\n// This will run every time the app starts up.

Every Val Town account comes with a free SQLite database, hosted on [Turso](https://turso.tech/). This folder is broken up into two files:\n\n* `migrations.ts` - code to set up the database tables the app needs\n* `queries.ts` - functions to run queries against those tables, which are imported and used in the main Hono server in `/backend/index.ts`\n\n## Migrations\n\nIn `backend/database/migrations.ts`, this app creates a new SQLite table `reactHonoStarter_messages` to store messages. \n\nThis \"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.\n\nSQLite has much more limited support for altering existing tables as compared to other databases. Often it's easier to create new tables with the schema you want, and then copy the data over. Happily LLMs are quite good at those sort of database operations, but please reach out in the [Val Town Discord](https://discord.com/invite/dHv45uN5RY) if you need help.\n\n## Queries\n\nThe queries file is where running the migrations happen in this app. It'd also be reasonable for that to happen in index.ts, or as is said above, for that line to be commented out, and only run when actual changes are made to your database schema.\n\nThe queries file exports functions to get and write data.
