with 3 sample topics and 5 messages if empty.\n\n## How It Uses vtrr\n\nThis demo showcases the key patterns of the vtrr framework:\n\n### 1. Route definitions with string-based loaders/actions\n\n```ts\nexport const routes = defineRoutes([\n {\n path: \"/\",\n Component: App,\n action: \"./routes/Topics.action.ts\", // server-only, never shipped to client\n children: [\n { index: true, Component: Home, loader: \"./routes/Home.loader.ts\" },\n { path: \"topics/:topicId\", Component: Topic, loader: \"...\", action: \"...\" },\n ],\n },\n]);\n```\n\nLoaders and actions are specified as **relative file paths** — the server dynamically imports them, while the client only gets lightweight stubs.\n\n### 2. Loader pattern — export a named `loader` function\n\n```ts\n// Home.loader.ts\nexport async function loader() {\n return { topics: await getAllTopics() };\n}\n```\n\n### 3. Action pattern — form mutations with redirects\n\n```ts\n// Topics.action.ts\nexport async function action({ request }) {\n const formData = await request.formData();\n const topic = await createTopic(formData.get(\"title\"));\n return redirect(`/topics/${topic.id}`);\n}\n```\n\n### 4. createApp with custom `` content\n\n```ts\nexport default createApp({\n routes,\n head: `\n Community Message Board\n \n `,\n});\n```\n\n## Styling\n\nUses [Twind](https://twind.style/) (Tailwind-in-JS) loaded from CDN — zero build step, just write Tailwind classes directly in JSX.\n",[],[202,287,195],"554e6224-0ff6-11f1-bbd5-42dde27851f2","Topics.action.ts","554e62ce-0ff6-11f1-bbd5-42dde27851f2","29c37dba-0ff6-11f1-925a-42dde27851f2",64,["D",1771768609272],"import { redirect } from \"https://esm.sh/react-router@7.5.0?deps=react@18.2.0,react-dom@18.2.0\";\nimport { createTopic } from \"../database/queries.ts\";\n\nexport async function action({ request }: { request: Request }) {\n const formData = await request.formData();\n const title = formData.get(\"title\") as string;\n\n if (!title || title.trim() === \"\") {\n throw new Response(\"Title is required\", { status: 400 });\n }\n\n const topic = await createTopic(title);\n return redirect(`/topics/${topic.id}`);\n}\n",[],[202,287,318,310],"routes","5f0247ea-0ff6-11f1-828e-42dde27851f2","TopicMessage.loader.ts","5f0248a8-0ff6-11f1-828e-42dde27851f2",68,["D",1771768625510],"import { getTopicById, getMessageById, getMessagesByTopicId } from \"../database/queries.ts\";\n\nexport async function loader({ params }: { params: Record }) {\n const topicId = parseInt(params.topicId!, 10);\n const messageId = parseInt(params.messageId!, 10);\n\n const topic = await getTopicById(topicId);\n if (!topic) {\n throw new Response(\"Topic not found\", { status: 404 });\n }\n\n const message = await getMessageById(messageId);\n if (!message || message.topicId !== topicId) {\n throw new Response(\"Message not found\", { status: 404 });\n }\n\n const messages = await getMessagesByTopicId(topicId);\n return { topic, messages };\n}\n",[],[202,287,318,320],"63d75362-0ff8-11f1-974d-42dde27851f2","Topic.tsx","5b1ed954-0ff6-11f1-828e-42dde27851f2",86,["D",1771769492646],"/** @jsxImportSource ../../.. */\nimport { React, useEffect, Link, useLoaderData, useParams } from \"../../../mod.ts\";\nimport { Message, Topic } from \"../types.ts\";\nimport { MessageForm } from \"../components/MessageForm.tsx\";\nimport { MessageList } from \"../components/MessageList.tsx\";\nimport { SearchForm } from \"../components/SearchForm.tsx\";\n\ninterface TopicDetailData {\n topic: Topic;\n messages: Message[];\n}\n\nexport function Topic() {\n const { topic, messages } = useLoaderData() as TopicDetailData;\n const { messageId } = useParams();\n const highlightedMessageId = messageId ? parseInt(messageId, 10) : undefined;\n \n // Scroll to highlighted message if messageId is provided\n useEffect(() => {\n if (highlightedMessageId) {\n const messageElement = document.getElementById(`message-${highlightedMessageId}`);\n if (messageElement) {\n messageElement.scrollIntoView({ behavior: \"smooth\", block: \"center\" });\n }\n }\n }, [highlightedMessageId]);\n \n return (\n
