Running tests using a local open-source backend
Convex recently released an open source version of the backend. We can use this to unit test Convex functions by running them with a local backend. These tests will work by running a backend locally, pushing your code, and using the `ConvexClient` to execute queries and mutations from your favorite testing framework and asserting on the results.

Testing React Components with Convex
Oftentimes during testing we want to mock out our backend so we can unit test our UI components without talking to our actual server code.
In this article, we’ll explore options for testing React components that call Convex React hooks using mocking and dependency injection. To do this, I’ve written a sample TypeScript React app using the Vitest testing framework. The patterns presented in this post are also applicable to other JavaScript apps and frameworks.

Backend Matters (Making Fast5 #2)
Why does anything really need to run on the server anymore? And even if it does, do I, the developer, need to be so involved?
Yes! Even in a serverless world, the backend computing context being a real, discrete environment that you have control and influence over is not only necessary but hugely beneficial.

Convex vs. Relational Databases
Relational databases are powerful tools for persisting data, but using them to build interactive web apps requires a lot of work. A web app architecture built on a relational database is an entire cluster of databases, backends, caching nodes, and Pub/Sub servers. And even after you invest in all of that infrastructure you'll still need to explicitly define your database schema upfront and write cumbersome SQL queries.
At Convex we believe that web developers shouldn't have to worry about any of this. We can handle the servers, caching, and reactivity and you can focus on your product.
