How to Fix React Context Undefined in AI-Built Apps
React context returns undefined when consumed in child components. AI-generated context code often wraps providers incorrectly or accesses context outside the provider tree.
Error messages you might see
TypeError: Cannot read properties of undefined (reading 'user')Error: useAuth must be used within an AuthProviderWhy this happens in AI-generated code
Component outside provider
AI renders components that use context outside the provider boundary, often in layout files or parallel routes.
Missing provider in the component tree
AI creates the context and consumer but forgets to wrap the app with the provider.
Server component using client context
AI tries to use useContext in a server component, where React context is not available.
How to fix it
Wrap providers in root layout
Place context providers in a client component wrapper and include it in your root `layout.tsx` to cover all routes.
Add a helpful error message to hooks
Check for undefined in custom hooks: `const ctx = useContext(MyContext); if (!ctx) throw new Error('useMyContext must be within MyProvider');`.

Frequently asked questions
Can I use React context in server components?
No. Context is a client-side feature. Pass data as props to server components or use server-side alternatives like cookies or headers.
How do I avoid prop drilling without context?
Consider Zustand or Jotai for global state. For server data, use React Server Components to fetch data where it's needed.
