How can I improve TypeScript performance when using complex types in a large React app?
I'm building a feature where I've been banging my head against this for hours... I'm relatively new to this, so bear with me. Currently developing a large-scale React application using TypeScript and facing noticeable performance lags, especially during component re-renders. The app employs various complex types, including interfaces and generics, which might be contributing to the slowdowns. I've tried using `React.memo` for memoizing components, but it only marginally improves the situation. Here's an example of how I've structured a component: ```typescript interface User { id: number; name: string; details: { age: number; email: string; }; } const UserProfile: React.FC<{ user: User }> = React.memo(({ user }) => { console.log('Rendering UserProfile'); return <div>{user.name}</div>; }); ``` I also implemented `useCallback` to memoize event handlers, but the performance still feels sluggish, particularly with a large list of users being rendered. Here's a snippet where I map over the user list: ```typescript const UserList: React.FC<{ users: User[] }> = ({ users }) => { const handleClick = useCallback((id: number) => { console.log(`User ${id} clicked`); }, []); return ( <div> {users.map(user => ( <UserProfile key={user.id} user={user} onClick={() => handleClick(user.id)} /> ))} </div> ); }; ``` Beyond basic optimizations, I'm curious if there's a more effective strategy for managing complex types and reducing re-renders. Should I consider flattening my data structure or perhaps restructuring some of my types? Also, are there any TypeScript specific optimizations or patterns that can help with this scenario? Any advice on profiling tools or libraries that could assist in tracking down performance bottlenecks would also be appreciated! My development environment is macOS. For context: I'm using Typescript on Ubuntu. Any help would be greatly appreciated! Any examples would be super helpful. I'd be grateful for any help.
