React Toolroom

A lightweight toolset for React developers.

中文 | English

Why React Toolroom?

• Memo optimization - Automatic event handler memoization
• Async data fetching - Simple hooks for API calls
• Zero dependencies - Tiny bundle size
• TypeScript first - Full type safety

Install

npm i react-toolroom

Modules

Core Module

import { memo } from 'react-toolroom';

// Automatically memoizes event handlers
const Button = memo(({ onClick, children }) => {
  return <button onClick={onClick}>{children}</button>;
});

Async Module

import { 
  useResult, 
  useLoading, 
  useRun, 
  useInjectable, 
  useError,
  useCache 
} from 'react-toolroom/async';

// Create a data fetcher
const fetchUsers = useInjectable(async () => {
  const res = await fetch('/api/users');
  return res.json();
});

// Use in component
function UserList() {
  const users = useResult(fetchUsers);
  const loading = useLoading(fetchUsers);
  const error = useError(fetchUsers);
  
  useRun(fetchUsers, []);
  
  if (loading) return <Spinner />;
  if (error) return <Error error={error} />;
  
  return <ul>{users.map(u => <li>{u.name}</li>)}</ul>;
}

// With caching
function CachedUserList() {
  const stale = useCache(fetchUsers, cacheProvider, 60000);
  // ...
}
