Link Shortener (ft. Convex custom domains)

Hey everyone, You might see cvx.so links around Convex content, such as https://cvx.so/fireship for our recent fireship ad campaign. For the last 18+ months, this short link service has been powered by a Convex project: https://github.com/jamwt/convex-link-shortener Shamefully though, this redirection service has delivered an entire react app to your browser to work. That app established a connection to a Convex deployment, and resolved the domain / path to a full URL using a Convex query. Finally, the app issued a window.location.replace to achieve the redirection. Code here: https://github.com/jamwt/convex-link-shortener/blob/main/src/App.jsx#L6 While this works, it's extremely heavyweight for a link shortener. It also means curl and other things that don't run JavaScript are out of luck. But since Convex didn't have custom domains, it was the only way to go. Well, fast forward to today! We just added an HTTP endpoint at the .site URL: https://github.com/jamwt/convex-link-shortener/commit/2c480aad962c66c7f7bf74c6970ee1be921150ca#diff-22ae6ac3563719a97f99af3980d10844cb0544e14f25f6c2ca41155c4c86eea5 Then, using Convex's brand new "custom domains" feature, we're aliasing cvx.so to the HTTP action domain, aromatic-magpie-742.convex.site. Voila! A high-perf redirection service without any react app needed. I've kept the react app in the codebase in case you want to use that method, though. Feel free to use this link shortener for anything you need. This custom domain feature will be released to Convex Pro customers... very soon. 😄 It will make developing all sorts of headless/API service really easy, and we're very excited about it. Stay tuned! 📺 Happy to answer any questions about custom domains, this link shortener, or headless service development on Convex.

Notes from our Internal "Build Convex Components Day"

Today our team is building Convex components using our internal alpha. Here are some of the projects the team is working on (or has already finished): * Workflow system (Inngest clone). A nice DSL that uses async/await to express several steps in a long-running workflow. Automatically retries each step as idempotent upon temporary failures. * Geospatial Indexing. Provides high performance geospatial indexing by using Uber's h3 library + Convex's indexes. * Action retrier. A packaged up version of Convex's https://github.com/JamesCowling/convex-action-retrier that uses components and a client library for less boilerplate. * Push notifications component. Integrates with common mobile push notification services. * Notification tray component. Client + server package for easily batching up messages for a user that they need to acknowledge within a product. * Payments component. Integrate with Stripe easiliy. * Presence tracking. Wrap up efficient, high performance presence system into a component. * Migrations. Feel out moving the various migrations helpers ( https://stack.convex.dev/migrating-data-with-mutations ) into a component * CDN Component Automatically reflect static assets out of Convex storage into a CDN like cloudflare * Expiring Storage URLs Wrapper that makes file storage assets only valid for some specified period of time * Web Crawler Crawls a website in the background and makes the contents available to your Convex app. * Sharded Counter. A port of @Web Dev Cody 's high-performance counter. We'll follow up here with more notes & more components as we get them. So far, pretty exciting! Fire away with any questions.

Convex full-text search, deep dive

llama farm

The intrepid @ian recently created a pretty cool project that allows a bunch of random computers (your laptop, fly.io machines, whatever) running ollama3 to collectively run all the LLM work for a chat application. All this work is coordinated using Convex as a kind of job queue. This allows the LLM cluster to be scaled up, and nothing needs to expose ports to the Internet to participate. Pretty neat idea!
