useRouter

根据popstate、hashchange监听路由变化，

const historyEvent=browserRouter?'popstate':'hashchange';
const changeEvent=()=>changeRouter();
window.addEventListener(historyEvent,changeEvent,false);

路由切换。history.pushState history.replaceState

const historyEvents=(path,params,event='pushState')=>{
  history[event](params,null,path);
  changeRouter(path,params);
};
const push=({path,params})=>{
  historyEvents(path,params);
};
const replace=({path,params})=>{
  historyEvents(path,params,'replaceState');
};

根据当前路由找到对应components

const formatMenu=(router,path,params)=>{
  const {result,current}=getCurrent(router,path,params);
  const menu=filterMenu(result);
  return {
    current,
    menu,
  };
};

lazyload components

const loader=async props=>{
  let component=await props.component;
  component=component.default??res;
  return component;
};

fetch data

const fetchData=async ()=>{
  try{
    const result=await resolve(params);
    setPropsResolve(result);
  }catch(err){
    setPropsResolve(err);
  }
};

errorBoundary

export default class ErrorBoundary extends React.Component{
  state={
    error:null,
  };
  static getDerivedStateFromError(error){
    return {error};
  }
  render(){
    const {error}=this.state;
    const {fallback,children}=this.props;
    if(error){
      return fallback(error);
    }
    return children;
  }
}

<ErrorBoundary>
  <Suspense fallback={handleLoading(Loading)}>
    {comp}
  </Suspense>
</ErrorBoundary>

Link

const Link=props=>{
  const {to,children,...rest}=props;
  const handleClick=e=>{
    e.preventDefault();
    emit(pushEvent,to);
  };
  return <a onClick={e=>handleClick(e)} href={to?.path??to??''} {...rest}>{children}</a>;
};

配置示例

install

npm i @huxy/router

使用

const App=()=>{
  const {components,loading}=useRouter(yourConfigs);
  return <>
    {components}
    {loading&&<Spinner global />}
  </>;
};

配置

全局配置

const browserRouter=!process.env.isDev;
const idKey='url';
const title='项目管理平台';
const theme='dark';
let whiteList=['/dashboard/app4'];
whiteList=browserRouter?whiteList:whiteList.map(v=>`#${v}`);
const beforeRender=input=>{
  if(whiteList.includes(input.path)){
    return {path:'/sign/signin'};
  }
};
const afterRender=output=>{
  console.log(output);
};

export default {
  browserRouter,
  idKey,
  title,
  theme,
  beforeRender,
  // afterRender,
};

• browserRouter：是否为browserHistory
• idKey：路由key值。如：url
• childKey：子层级key值。如：children
• title：页面title。
• beforeRender：路由守卫，渲染前回调。
• afterRender：渲染完回调。
• basepath：路由前缀。
• others：其它设置。

组件配置

url:'/dashboard',
redirect:'/dashboard/app1',
name:'Dashboard',
icon:'icon-dashboard',
children:[
  {
    url:'/app1',
    name:'app1',
    icon:'icon-th-list',
    component:<App1 />,
    loadData:{
      user:fetchUser,
    },
    errorBoundary:true,
  },
  {
    url:'/app2',
    name:'app2',
    icon:'icon-th-list',
    component:()=>import('./app2'),
    denied:true,
  },
  {
    url:'/app3',
    name:'app3',
    icon:'icon-th-list',
    component:()=>import('./app3'),
    resolve:{
      user:fetchUser,
    },
  },
  {
    url:'/app4',
    name:'admin',
    icon:'icon-th-list',
    component:<h1>app4</h1>,
    hideMenu:false,
  },
]

• path：路径
• name：展示名
• icon：图标
• redirect：重定向
• children：子菜单
• component：页面
• denied：权限控制
• hideMenu：菜单隐藏展示
• errorBoundary：错误边界。默认有错误边界处理，可自定义。
• resolve：数据请求并缓存，可用store.getState(key)获取，store.setState(state)更新。
• loadData:数据请求，不缓存数据。

工具函数

• store：提供数据全局管理功能。setState、getState、subscribe
• eventBus：订阅发布功能。on、emit、off
• updateRouter：更新路由配置
