Testing
Remix organizes your app around routes, loaders, and actions. Loaders fetch data before the route renders. Actions handle form submissions. Route components display the data. This structure makes testing straightforward — each piece has clear inputs and outputs you can verify independently. This guide covers the full Remix testing stack: Vitest
Testing
Remix and Next.js are both full-stack React frameworks, but their approaches to server-side code differ in ways that significantly affect how you write tests. This guide compares the testing experience of both frameworks — what's easier, what's harder, and what patterns carry over between
Testing
Forms in Remix work differently from most React frameworks. Remix forms submit to server actions, which return structured data or throw redirects. Testing this pattern requires understanding both sides: the action logic and the component that displays action errors. This guide covers everything you need to test Remix forms thoroughly:
Testing
Remix loaders and actions are the backend of your application. Loaders fetch data; actions handle mutations. Both are pure functions that take a request and return a response — which makes them easy to test without a running server. This guide goes deep on testing Remix loaders and actions: constructing requests,
Testing
Remix's file-based routing, nested routes, and server-side rendering require E2E tests that exercise the full stack. Playwright is the right tool: it runs tests in real browsers, handles JavaScript-rendered content, and integrates cleanly with Remix's dev server. This guide covers Playwright setup for
