AI coding is here: The most productive developers are leveraging AI to speed up their workflows. This ranges from asking models questions about system design to letting AI take the driver's seat with tools like Cursor Composer.
Here’s a cheatsheet with examples of conversions between SQL queries and Convex queries. This article is geared towards developers (and LLMs) who have familiarity with SQL and want to translate those familiar patterns into Convex queries. You'll learn how to `UNION`, `JOIN`, `DISTINCT`, do `WHERE` clauses, and `SELECT` fields.
Coding agents can do more autonomously when they write code that has tight, automatic feedback loops; use systems that express everything in standard, procedural code; and have access to strong, foolproof abstractions.
Explore techniques to improve transaction throughput and concurrency in ACID databases by reducing conflicts and optimizing database reads. This guide covers patterns like Queue, Hot and Cold Tables, and Predicate Locking with clear examples using Convex, providing developers with tools to handle high-throughput workflows effectively.
We can categorize sync platforms across nine dimensions: data size, data update rate, the structure of the data, input latency, offline support, number of concurrent clients, centralization, flexibility, and consistency.

New convex-helpers are available now for fetching streams of documents, merging them together, filtering them them out, and paginating the results. With these helpers, you can replicate patterns you may know from SQL: UNION ALL, JOIN, DISTINCT, GROUP BY, and WHERE clauses where index fields are skipped.

Convex Panel simplifies development by integrating Convex’s powerful dashboard directly into the dev environment, eliminating the need to switch between browser tabs. Built as a React component, it provides real-time logs, table editing, and performance insights seamlessly within your workflow. This tool enhances productivity, streamlines debugging, and optimizes backend management for developers using Convex.

Moving data between databases is never fun, but I needed to get 2 million MongoDB documents into Convex without losing my mind. This post walks through my migration script, covering everything from connecting databases to handling schema changes, batch processing, and error handling. If you’re thinking about moving from MongoDB to Convex, consider this your survival guide—coffee highly recommended!

Authentication issues in real-time applications can cause security risks, especially when client-side queries run before validation. Ensuring authentication at the server (Next.js middleware), client (useConvexAuth()), and database (Convex functions) helps prevent unauthorized access. Using middleware, enforcing authentication in Convex functions, and leveraging custom hooks improves security and performance.

I reimplemented Mastra’s agentic workflows with durable functions in Convex, and it was the wrong decision. Look at three common strategies (reimplementation, API wrapping, and “blessed” plugin paths), along with learnings along the way and reflections on what I’d do differently next time. TL;DR: Do less, do it smarter, and prototype faster.
