In the end, the root cause was a deployment timing issue where database migrations were deployed successfully, but our application code deployment hung for several minutes. The new database migrations were incompatible with the old application code and crashed the process. \n\nWe aim to make all database migrations maintain backward compatibility, but in this case, we only discovered through the delayed deployment feedback that the new migrations were not compatible with previous versions.\n\n## Timeline\n\n- **10:11AM ET** - We merged the new migration and application code\n- **10:16AM ET** - We got pinged for downtime\n- **10:17AM ET** - We posted that HTTP vals are down in the new #service-status channel\n- **10:18AM E**T - The new application code deployment was still lagging\n- **10:19AM ET** - We rolled back to an earlier deployment on Render, which Render rejected because the earlier migration had succeeded, so the ‘old migration’ check prevented it from entering production.\n- **10:22AM ET** - We pushed something we thought could be a fix\n- **10:28AM ET** - We notified everyone that we’re back up.\n- **10:41AM ET** - We posted an update in #service-status with a bit more context and apology\n\n## Impact\n\n- HTTP vals returned 503 errors for ~12 minutes, and all other val types did not run.\n- The [val.town](http://val.town) site remained up.\n\n## Next Steps\n\nReliability is important to us and we’ve taken steps to make sure this doesn’t happen again. We’ve added a test to ensure database migrations are backward compatible, which we’ll run before we deploy any new code that includes database migrations.",[],[196,212],{"_107":220,"_99":221,"_154":222,"_156":197,"_157":141,"_158":146,"_159":122,"_109":223,"_104":33,"_161":206,"_163":224,"_164":27,"_165":-5,"_166":225,"_103":226},"5ef20978-0ffe-11f0-a229-569c3dd06744","vt-blog.md","87095612-ae66-42a2-a622-8a61fb10dfbe",["D",1743624563738],"---\ntitle: Migrating the Val Town Blog to Val Town\ndescription: How we migrated the Val Town Blog from Astro & Cloudflare Pages to be hosted directly on Val Town in a day\npubDate: 2025-04-02T00:00:00.000Z\nauthor: Steve Krouse\n---\n\nToday I migrated the Val Town Blog from Astro and Cloudflare Pages to be hosted directly on Val Town.\nWith some cleverness and a bit of vibe coding, I was able to start and complete this migration in a day.\n\n## The Old Architecture\n\nPreviously, our blog was:\n\n- Built with Astro, a modern static site generator\n- Deployed to Cloudflare Pages\n- Updated through a GitHub workflow\n\nWhile this setup worked well, we wanted:\n\n1. A browser-based editor\n2. Instant deploys (on feature branches and production)\n3. To dogfood\n\n## The New Architecture\n\nThe new blog:\n\n1. Hosts new blog posts directly on Val Town as markdown files\n2. Proxies requests for old blog posts to the original Cloudflare Pages deployment\n3. Generates the full lists of posts (for the homepage) by splicing together the new posts and the old posts, which it gets via the old blog's RSS feed\n\n### Technical Implementation\n\nWe implemented the new blog system using:\n\n- React for rendering components\n- Tailwind CSS for styling\n- Unified/Remark/Rehype for markdown processing\n- RSS Parser for fetching posts from the old blog\n\n#### Rendering old posts\n\nProxying is as easy as:\n\n```ts\nconst OLD_BLOG_URL = \"https://val-town-blog.pages.dev/\";\nconst response = await fetch(\n new Request(OLD_BLOG_URL + url.pathname + url.search, {\n method: request.method,\n headers: new Headers({ ...Object.fromEntries(request.headers) }),\n }),\n);\n```\n\n#### Fetching old posts\n\nWe fetch old posts via the `https://val-town-blog.pages.dev/rss.xml`,\nand combine them with the locally-hosted posts. We cache them both in-memory\non server startup.\n\n```ts\n// Example of how we fetch blog posts\nasync function getAllBlogPosts() {\n // Get local posts from markdown files\n const localPosts = await getLocalBlogPosts();\n \n // Get posts from RSS feed\n const rssPosts = await getRssBlogPosts();\n \n // Merge and sort by date\n return [...localPosts, ...rssPosts].sort((a, b) => {\n return new Date(b.pubDate).getTime() - new Date(a.pubDate).getTime();\n });\n}\n```\n\n## Conclusion\n\nSo far we've had reasonable success with this technique of migrating to Val Town quickly by proxying most old content, \nand only rebuilding the homepage. I first used this technique on my personal website, [stevekrouse.com](https://stevekrouse.com),\nand was pleased to see it continue to work here. If you, dear reader, have a blog you'd like to migrate to Val Town in this way\nand get stuck, shoot me an email at steve@val.town – I'd be happy to

Val Town Blog\n\n## Overview\n\nThe Val Town Blog has undergone a migration from its original hosting on Astro and Cloudflare Pages to being hosted directly on Val Town. This repository contains the code that powers the current blog implementation.\n\n## How It Works\n\n### Blog Architecture\n\n- **New Posts**: New blog posts are written in markdown with YAML frontmatter and stored in the `/blog-posts` directory\n- **Legacy Posts**: For older blog posts, we proxy requests to the original blog hosted at Cloudflare Pages\n- **Homepage**: The homepage is dynamically constructed by:\n 1. Reading local markdown files from the `/blog-posts` directory\n 2. Parsing the RSS feed from the old blog at `https://val-town-blog.pages.dev/rss.xml`\n 3. Merging and sorting the posts by date\n 4. Rendering the combined content with a consistent design using Tailwind CSS\n\n### Components Structure\n\n- **`/index.tsx`**: Main entry point that handles routing and proxying\n- **`/components/`**: React components for rendering the blog\n - **`Layout.tsx`**: Shared layout component with header and Tailwind setup\n - **`HomePage.tsx`**: Renders the blog homepage with the list of posts\n - **`BlogPost.tsx`**: Renders individual blog posts\n- **`/utils/blogPosts.ts`**: Utilities for fetching, parsing, and caching blog posts\n- **`/blog-posts/`**: Directory containing markdown files for blog posts\n\n### Technical Stack\n\n- **React**: For rendering components\n- **Tailwind CSS**: For styling (via CDN)\n- **Unified/Remark/Rehype**: For markdown processing with GitHub Flavored Markdown support\n- **RSS Parser**: For fetching posts from the old blog's RSS feed\n- **Gray Matter**: For parsing YAML frontmatter\n\n## Adding New Blog Posts\n\nTo add a new blog post to the Val Town Blog:\n\n1. Create a markdown file in the `/blog-posts` directory with YAML frontmatter:\n\n```markdown\n---\ntitle: My New Blog Post\ndescription: A brief description of the post\npubDate: 2025-04-01T00:00:00.000Z\nauthor: Your Name\n---\n\nContent of your blog post in markdown format...\n```\n\n2. The post will automatically appear on the homepage and be accessible at `/blog/[filename]` (without the .md extension)\n\n## Markdown Features\n\nThe blog supports GitHub Flavored Markdown (GFM) with:\n\n- Tables\n- Task lists\n- Strikethrough\n- Autolinks\n- Code syntax highlighting\n- Heading IDs (via rehype-slug)\n\n## Development\n\nWhen modifying the blog system:\n\n1. Update the React components in the `/components` directory\n2. Modify the blog post utilities in `/utils/blogPosts.ts`\n3. Test changes by visiting the homepage and individual blog posts\n4. For styling changes, use Tailwind CSS classes\n\n## Caching\n\nBlog posts are cached in memory to improve performance:\n\n- The cache is initialized when the server starts\n- It has a TTL of 5 minutes before being refreshed\n- This reduces the need to read files and parse RSS on every request",[],[324],{"_107":331,"_99":332,"_154":333,"_156":-5,"_157":141,"_158":146,"_159":122,"_109":334,"_104":33,"_161":206,"_163":70,"_164":27,"_165":-5,"_166":335,"_103":336},"5ef23114-0ffe-11f0-a229-569c3dd06744","TODOs.md","642f485c-2fd9-4d18-b856-70afe0170990",["D",1743624563738],[],[332],{"_107":338,"_99":339,"_154":340,"_156":-5,"_157":141,"_158":146,"_159":122,"_109":341,"_104":33,"_161":342,"_163":343,"_164":27,"_165":-5,"_166":344,"_103":345},"5ef2339e-0ffe-11f0-a229-569c3dd06744","index.ts","a65b86ed-c832-4b91-b815-fcebed32eeae",["D",1743624563738],"http","import

The new database migrations were incompatible with the old application code and crashed the process. \n\nWe aim to make all database migrations maintain backward compatibility, but in this case, we only discovered through the delayed deployment feedback that the new migrations were not compatible with previous versions.",[196,212],{"_154":213,"_104":94,"_109":528,"_157":141,"_346":529},["D",1743624729210],[530],{"_107":531,"_157":141,"_154":213,"_99":212,"_163":70,"_161":206,"_104":33,"_156":197,"_109":528,"_158":94,"_165":-5,"_159":27,"_164":27,"_103":532},"c19238e6-0ffe-11f0-85ae-569c3dd06744",[196,212],{"_154":333,"_104":146,"_109":534,"_157":141,"_346":535},["D",1743624563738],[536,538,541,544,547,550,553,556,560,563,566,569,572,575],{"_107":331,"_157":141,"_154":333,"_99":332,"_163":70,"_161":206,"_104":33,"_156":-5,"_109":534,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":537},[332],{"_107":314,"_157":141,"_154":316,"_99":315,"_163":318,"_161":173,"_104":33,"_156":270,"_109":539,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":540},["D",1743624563738],[269,315],{"_107":268,"_157":141,"_154":270,"_99":269,"_163":-5,"_161":162,"_104":33,"_156":-5,"_109":542,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":543},["D",1743624563738],[269],{"_107":169,"_157":141,"_154":171,"_99":170,"_163":174,"_161":173,"_104":33,"_156":155,"_109":545,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":546},["D",1743624563738],[153,170],{"_107":220,"_157":141,"_154":222,"_99":221,"_163":224,"_161":206,"_104":33,"_156":197,"_109":548,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":549},["D",1743624563738],[196,221],{"_107":235,"_157":141,"_154":237,"_99":236,"_163":239,"_161":173,"_104":33,"_156":231,"_109":551,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":552},["D",1743624563738],[230,236],{"_107":152,"_157":141,"_154":155,"_99":153,"_163":-5,"_161":162,"_104":33,"_156":-5,"_109":554,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":555},["D",1743624563738],[153],{"_107":557,"_157":141,"_154":203,"_99":202,"_163":518,"_161":206,"_104":33,"_156":197,"_109":558,"_158":146,"_165":-5,"_159":27,"_164":27,"_103":559},"5ef20770-0ffe-11f0-a229-569c3dd06744",["D",1743624563738],[196,202],{"_107":274,"_157":141,"_154":276,"_99":275,"_163":278,"_161":173,"_104":33,"_156":270,"_109":561,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":562},["D",1743624563738],[269,275],{"_107":282,"_157":141,"_154":284,"_99":283,"_163":286,"_161":173,"_104":33,"_156":270,"_109":564,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":565},["D",1743624563738],[269,283],{"_107":290,"_157":141,"_154":292,"_99":291,"_163":294,"_161":173,"_104":33,"_156":270,"_109":567,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":568},["D",1743624563738],[269,291],{"_107":178,"_157":141,"_154":180,"_99":179,"_163":182,"_161":173,"_104":33,"_156":155,"_109":570,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":571},["D",1743624563738],[153,179],{"_107":243,"_157":141,"_154":245,"_99":244,"_163":247,"_161":173,"_104":33,"_156":231,"_109":573,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":574},["D",1743624563738],[230,244],{"_107":338,"_157":141,"_154":340,"_99":339,"_163":343,"_161":342,"_104":33,"_156":-5,"_109":576,"_158":146,"_165":-5,"_159":122,"_164":27,"_103":577},["D",1743624563738],[339],"page","hasNext","routes/_app","actionData","errors"]
