react-router-v4

问题 I have written an SPA which caches all its assets like bundle-1234.js which are required in the index.html . I'm wondering that when the bundle-1234.js is downloaded, cached and executed how does the app ever refresh when the bundle changed to bundle-9876.js ?

问题 I used react-router-dom and I build my react-app. When I deploy it on the server, I get a blank page and the console is empty. My App.js is : import React, { Component } from 'react'; import { Route, Switch, BrowserRouter} from 'react-router-dom'; import Agenda from './components/Agenda/Agenda'; import Planning from './components/Planning/Planning'; class App extends Component { render() { return ( <div> <BrowserRouter basename="/"> <Switch> <Route exact path="/" component={Agenda} /> <Route

问题 Is it possible to apply logic to a component before navigating to a different route? For example, my component looks something like this: class Example extends React.Component { //Handles logic for when user leaves page handlePageExit = () => { console.log("Leaving page..."); } //Set onBeforeUnload event listener so handlePageExit function is called when user closes or refreshes page componentDidMount = () => { window.addEventListener("onbeforeunload", this.handlePageExit); } //This hook is

问题 I'm trying to implement a facebook-like homepage (i.e. a list of posts with comments). PostList is the component in charge of loading the post list (using fetch in its componentDidMount() ), itself being a child of the component HomePage . I have another component for the navigation bar called NavBar with a <Link> component (from react-router-dom ) to the route of my HomePage component ('/'). When I'm on any page other than '/', using the link works fine: the Router mounts HomePage , and then

问题 My issue here is incredibly similar if not exactly the same as the one outlined in this issue. Unfortunately, I haven't been able to resolve it using the strategy it provides. So here are my own details: I am using Create React App , React Router 4 , Express , and Heroku and have followed the instructions here with regards to setting up a server with CRA. Locally, I am able to access routes such as myapp/about , yet after building and pushing to heroku, these 404. I can navigate to this route
