When a user directly accesses a URL:\n\n1. The server receives the request\n2. It runs the appropriate loaders/actions for the matched route\n3. The page is rendered with the data and sent to the client\n4. The client hydrates the page with `createBrowserRouter` and `RouterProvider`\n\n### Client-Side Navigation\n\nAfter the initial page load, navigation happens entirely on the client:\n\n1. React Router handles link clicks and form submissions\n2. Data is fetched asynchronously using loaders and actions\n3. A loading spinner is displayed during data fetching\n4. The UI updates without a full page reload\n\n### Data Flow\n\n1. **Topics**: Stored in SQLite with title and creation timestamp\n2. **Messages**: Linked to topics with content and creation timestamp\n3. **Search**: Queries both topics and messages, with results in the URL\n\n### URL Structure\n\n- `/` - Home page with list of topics\n- `/topics/new` - Create new topic\n- `/topics/:topicId` - View a topic and its messages\n- `/topics/:topicId/messages/:messageId` - Direct link to a message\n- `/search?q=query` - Search results\n\n## Getting Started\n\n1. Clone the repository\n2. Run the application with `deno run -A backend/index.ts`\n3. Visit `http://localhost:3000` in your browser\n\n## Implementation Details\n\nThis application demonstrates a \"Val Town fullstack framework\" approach, combining:\n\n- **Hono**: For server-side routing and handling\n- **React Router 7**: For both server and client-side routing\n- **SQLite**: For data persistence\n- **TypeScript**: For type safety across the stack\n\nThe code is structured to be idiomatic and simple, serving as a reference for building full-stack applications with React Router 7.","label",[140],"5343c3fe-14cd-11f0-b10b-569c3dd06744","shared","add21c84-9f00-4405-af88-6ec5134089df",2,["D",1744153254621],[151],"65bd0400-14cd-11f0-9e26-569c3dd06744",["D",1744153285607],[43],"5ae47a2c-14cd-11f0-bbde-569c3dd06744","backend","50aca1db-e744-46f9-883e-ba00e55ffc58",["D",1744153267418],[160],"pulls","branches","forks","envVars",{"_171":146,"_173":146},"connections",{"_171":146,"_172":146},"count","unfilledCount","emptyCount",{"_47":159,"_32":160,"_30":161,"_142":-5,"_40":41,"_39":68,"_144":63,"_37":226,"_13":146,"_34":45,"_35":-5,"_24":25,"_148":-5,"_184":227,"_27":228},{"_47":222,"_32":214,"_30":208,"_142":161,"_40":41,"_39":68,"_144":63,"_37":223,"_13":146,"_34":45,"_35":-5,"_24":25,"_148":-5,"_184":224,"_27":225},{"_47":215,"_32":216,"_30":217,"_142":208,"_40":41,"_39":68,"_144":25,"_37":218,"_13":146,"_34":191,"_35":219,"_24":25,"_148":-5,"_184":220,"_27":221},{"_47":205,"_32":206,"_30":207,"_142":208,"_40":41,"_39":209,"_144":25,"_37":210,"_13":146,"_34":191,"_35":211,"_24":25,"_148":-5,"_184":212,"_27":213},{"_47":156,"_32":43,"_30":44,"_142":-5,"_40":41,"_39":14,"_144":63,"_37":202,"_13":146,"_34":45,"_35":-5,"_24":25,"_148":-5,"_184":203,"_27":204},{"_47":198,"_32":33,"_30":31,"_142":44,"_40":41,"_39":14,"_144":25,"_37":199,"_13":146,"_34":21,"_35":36,"_24":25,"_148":-5,"_184":200,"_27":201},{"_47":150,"_32":151,"_30":152,"_142":-5,"_40":41,"_39":153,"_144":63,"_37":195,"_13":146,"_34":45,"_35":-5,"_24":25,"_148":-5,"_184":196,"_27":197},{"_47":187,"_32":188,"_30":189,"_142":152,"_40":41,"_39":153,"_144":63,"_37":190,"_13":146,"_34":191,"_35":192,"_24":25,"_148":-5,"_184":193,"_27":194},{"_47":139,"_32":140,"_30":141,"_142":-5,"_40":41,"_39":143,"_144":25,"_37":183,"_13":146,"_34":21,"_35":147,"_24":25,"_148":-5,"_184":185,"_27":186},["D",1744153251229],"children",[],[140],"5343bcb0-14cd-11f0-b10b-569c3dd06744","types.ts","5343bd78-14cd-11f0-b10b-569c3dd06744",["D",1744153254621],"script","/**\n * Topic model representing a discussion thread\n */\nexport interface Topic {\n id: number;\n title: string;\n createdAt: string;\n}\n\n/**\n * Message model representing a post within a topic\n */\nexport interface Message {\n id: number;\n topicId: number;\n content: string;\n createdAt: string;\n}\n\n/**\n * Search results containing matching topics and messages\n */\nexport interface SearchResults {\n topics: Topic[];\n messages: Message[];\n query: string;\n}",[],[151,188],["D",1744153254621],[181],[151],"65bcfd3e-14cd-11f0-9e26-569c3dd06744",["D",1744153285607],[],[43,33],["D",1744153285607],[179],[43],"62297fd0-14cd-11f0-800b-569c3dd06744","queries.ts","6229805c-14cd-11f0-800b-569c3dd06744","4af61b55-4e6e-48ee-bb08-a35baadaf267",4,["D",1744153279616],"import { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nimport { Message, Topic, SearchResults } from \"../../shared/types.ts\";\nimport { MESSAGES_TABLE, TOPICS_TABLE } from \"./migrations.ts\";\n\n/**\n * Get all topics ordered by creation date (newest first)\n */\nexport async function getAllTopics(): Promise {\n const result = await sqlite.execute(`\n SELECT id, title, createdAt \n FROM ${TOPICS_TABLE} \n ORDER BY createdAt DESC\n `);\n \n return result.rows as Topic[];\n}\n\n/**\n * Get a single topic by ID\n */\nexport async function getTopicById(id: number): Promise {\n const result = await sqlite.execute(`\n SELECT id, title, createdAt \n FROM ${TOPICS_TABLE} \n WHERE id = ?\n `, [id]);\n \n return result.rows.length > 0 ?
