如何在 React 中轻松路由？使用 React Router！
开始 import React from "react"; import ReactDOM from "react-dom/client"; import { createBrowserRouter, RouterProvider, } from "react-router-dom"; import Root from "./routes/root"; const router = createBrowserRouter([ { path: "/", element: <Root />, }, ]); ReactDOM.createRoot(document.getElementById("root")).render( <React.StrictMode> <RouterProvider router={router} /> </React.StrictMode> ); root 路由比较特殊。 Not Found import ErrorPage from "./error-page"; const router = createBrowserRouter([ { path: "/", element: <Root />, **errorElement: <ErrorPage />,** }, ]); ReactDOM.createRoot(document.getElementById("root")).render( <React.StrictMode> <RouterProvider router={router} /> </React.StrictMode> ); 嵌套路由 让 <Contact /> 渲染在 <Root /> 的 children(<Outlet />) 中： const router = createBrowserRouter([ { path: "/", element: <Root />, errorElement: <ErrorPage />, **children**: [ { path: "contacts/:contactId", element: <Contact />, }, ], }, ]); 使用 Layout 也能解决。

计数器 import { create } from 'zustand' const useStore = create(set => ({ count: 1, inc: () => set(state => ({ count: state.count + 1 })), })) function Controls() { const inc = useStore(state => state.inc) return <button onClick={inc}>one up</button> } function Counter() { const count = useStore(state => state.count) return <h1>{count}</h1> } 用法 创建状态 state 操作 action Basic typescript usage doesn’t require anything special except for writing create<State>()(...) instead of create(...)… import { create } from 'zustand' interface BearState { bears: number increase: (by: number) => void } const useBearStore = create<BearState>()((set) => ({ bears: 0, increase: (by) => set((state) => ({ bears: state.bears + by })), })) const useFishStore = create((set) => ({ salmon: 1, tuna: 2, deleteEverything: () => set({}, true), // clears the entire store, actions included deleteTuna: () => set((state) => omit(state, ['tuna']), true), })) const useSoundStore = create((set, get) => ({ sound: "grunt", action: () => { const sound = get().sound // you still have access to state outside of it through get // ... } }) export default useBearStore 在 react 之外使用呢？
