I’m excited to announce Convex Swift, which unlocks the ability to build iOS and MacOS clients for your Convex app.
Triggers automatically run code whenever data in a table changes. A library in the convex-helpers npm package allows you to attach trigger functions to your Convex database.
I was curious to see if I could prompt my way through developing an entire app with Cursor and Claude. It went pretty well - but there are some important caveats to keep in mind.
The term CRUD, or CRUD API, is often tossed around when interacting with databases or building backend APIs. This article will examine what CRUD is, what it’s suitable for, and its shortcomings. Finally, we’ll explore how to quickly implement a CRUD API using a modern backend like Convex.

Log streams like Axiom and Datadog can be used to provide powerful querying and alerting on logs and errors from your Convex functions, helping with debugging issues when they come up and providing early insights to detect smaller issues before they become bigger. This article covers how to do the several common things with either Axiom or Datadog hooked up as a Convex log stream including filtering to a request, logging structured metadata, and visualizing usage.

You'll often want to retrieve unique records from your database. While SELECT DISTINCT is the traditional way to do this in SQL databases, we've improved on this pattern in Convex by making it more consistent.

It was my goal to create an API that both feels natural to Android developers who have kept up with modern application architecture principles, as well something that feels like a natural fit in the Convex ecosystem.

Even though Convex supports the creation of cron jobs out of the box, until now, we've only supported static jobs. With user space crons, we now support the programmatic definition of crons at runtime.

When people want a full-stack framework, what they really want is an opinionated backend that interoperates seamlessly with their frontends in a way that empowers full-stack developers to easily build apps that can scale.

I recently built a full-stack app called notesGPT. It allows you to record a voice note, transcribes it, and extract action items and display them as action items. It’s fully open source and comes equipped with authentication, storage, vector search, action items, and is fully responsive on mobile for ease of use.

This year vector databases have sprung up like mushrooms to enable applications to retrieve context based on semantic search. A large portion of these applications have used the retrieved context to augment the ability of large language models (LLMs) in a pattern known as RAG. On November 7th OpenAI released its Assistants API, enabling the implementation of AI chat interfaces with context retrieval without needing a separate message store or vector database. Does this new API make vector databases obsolete?

Convex is a full-stack development platform and cloud database, including built-in vector search. In this third post in our [series](https://stack.convex.dev/ai-chat-using-openai-assistants-api), we’ll build an AI-powered chat interface using Convex, with our own message storage and context retrieval.
