Пример middleware

router.canActivate('profile', (router) => (toState, fromState, done) => { return isUserLoggedIn() .catch(() => Promise.reject({ redirect: { name: 'login' }})); });

router.navigate('profile', (err, state) => { // err is null state.name === 'login'; });

Link

import React from 'react' import { Link } from 'react-router5' function Menu(props) { return ( <nav> <Link routeName="home">Home</Link> <Link routeName="about">About</Link> <Link routeName="user" routeParams={{ id: 100 }}>User #100</Link> </nav> ) } export default Menu

Построение путей

const router = router5([ { name: 'admin', path: '/admin' }, { name: 'admin.users', path: '~//users?param1' }, { name: 'admin.user', path: '^/user/:id' }, { name: 'help', path: '^/help/*splat' } ]);

console.log(router.buildPath('admin')); // '/admin' console.log(router.buildPath('admin.users'); // '/users' console.log(router.buildPath('admin.users', { param1: true })); // '/users?param1=true' console.log(router.buildPath('admin.users', { id: 100 })); // '/user/100' console.log(router.buildPath('admin.user', { id: 100 })); // '/user/100' console.log(router.buildPath('help', { splat: [1, 2, 3] })); // '/help/1/2/3'

Decode и encode параметров

export default { name: 'help', path: ‘/help*slugs',

loadComponent: () => import('./index'),

encodeParams: ({ slugs }) => slugs.join('/'), decodeParams: ({ slugs }) => slugs.split('/'),

defaultParams: { slugs: [], }, };
