Common Bugs in Magic.dev-Generated Code

Large-context generation is powerful but increases the blast radius of any misunderstanding. The more files involved in a change, the more places where a subtle error can appear

Magic.dev's large-context approach means it may make very broad changes that affect many files simultaneously, increasing the risk that some changes are correct and others miss the mark. In Rust, generated code may compile but have subtle ownership issues that only manifest in specific usage patterns

Start by running your app through its complete user flow — sign up, use every feature, try edge cases like empty inputs and invalid data. Most Magic.dev bugs surface when you go off the happy path. Use your browser's developer tools to watch for console errors, failed network requests, and unhandled promise rejections. TypeScript's strict mode will catch many issues at compile time if it's not already enabled.

For async errors, wrap every server-side operation in try/catch blocks and return meaningful error messages. For state bugs, consider whether the state belongs in the URL, in a server component, or in client state — Magic.dev often defaults to client state when server state would be more appropriate. For data fetching issues, implement proper loading and error states for every data-dependent component.

The best way to prevent Magic.dev bugs from reaching production: enable TypeScript strict mode, add ESLint rules for common mistakes (no-floating-promises, exhaustive-deps), and write tests for critical user flows. Even basic smoke tests catch the majority of issues.
