Get started with backend development in Remix! You'll create your first API endpoints, handle web requests, serve JSON data, and read query parameters—testing everything right from the browser or curl.

Course 2

Handling Data with POST, PUT, PATCH and DELETE

4 lessons

16 practices

Expand your Remix API’s capabilities by learning to create, update, and delete data. You’ll implement handlers for POST, PUT, PATCH, and DELETE requests, work with request bodies, and build dynamic routes to manage individual resources.

Course 3

Building Robust and Modular APIs with Remix

4 lessons

16 practices

Strengthen your Remix API with shared validation, centralized response helpers, structured logging, and a clean service layer. You’ll refactor your routes to use these utilities and keep .tsx route files that also render a tiny component (to avoid Remix warnings).

Course 4

Project: Building a Task Manager API

3 lessons

10 practices

Build a fully functional backend API for managing tasks that mirrors the patterns you’ve already used for Users: centralized response helpers, a thin route layer wrapped with logging, and a clear service layer. Secure endpoints with an API key and add a small UI “playground” to exercise and validate behavior end-to-end.

Course 5

Production-Oriented Refactoring for a Remix Task API

3 lessons

11 practices

Strengthen the Task API with production-grade practices: introduce Zod validation for precise error messages, abstract data access behind a repository interface, and evolve from in-memory to file-backed persistence—all while keeping your routes thin, logged, and consistent with your existing response envelopes.

I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

Full Stack Engineer

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
