1. Architectural Patterns
PRO TIPImplementing modular monorepos with Nx workspaces and advanced React-Context Providers.
context/index.tsx
{`export const useUser = createGlobalProvider(
() => useContext(UserContext),
{
state: {
name: 'Anonymous',
credits: 100,
isPro: false
},
actions: {
updateProfile: async (data) => {
try {
const res = await api.patch('/user', data);
return res.data;
} catch (e) {
toast.error('Profile update failed');
return false;
}
}
}
}
);`}
components/UserCard.tsx
{`export function UserCard() {
const { user, updateProfile } = useUser();
const handleSubmit = async (e) => {
e.preventDefault();
await updateProfile({ name: 'New Name' });
};
return (
...
);
}`}
Tip: Always encapsulate context state with error handling and implement type declarations for type safety.
2. Advanced Performance Techniques
Implement next-level optimizations using React Query, Web Workers, and Suspense.
Client Caching
Optimize data loading with SWR and React Query
Web Workers
Offload heavy computations to background threads
Lazily Load Dependencies
Use dynamic imports with conditional loading
Using Suspense
{`function fetchUser() {
return new Promise((resolve, reject) => {
window.__user__ ? resolve(window.__user__) :
reject('Loading...');
});
}`}
Client Caching
{`const {
data: users,
isLoading,
error
} = useSWR('/api/users', fetcher);`}
