Proper way of handling conditional component render depending on route?

阅读更多关于 Proper way of handling conditional component render depending on route?

问题 I searched a lot on the Web and SO, asked in reactiflux chat, but didn't found a clean and non-hack-looking way of rendering some component depending of route/path. Let's say I have the <Header /> which should be shown on some pages and should be hidden on other ones. For sure I can use this string in Header component if (props.location.pathname.indexOf('/pageWithoutAHeader') > -1) return null That's totally fine, if /pageWithoutAHeader is the unique. If I need same functionality for 5 pages

react-router v4 nesting routing issue

I have a following situation: <Wrapper> <Container> <Route exact path="/" component={UserListing} /> <Route path="/user/:id" component={UserDetails} /> <Route exact path="(/|/user/\d+)" component={StaticComponent} /> </Container> <Route path="/create-account" component={CreateAccount}/> </Wrapper> Okey, so my case is simple: I don't want the Container component to render if path does not equal to "/" or "/user/:id" .

阅读更多关于 How to make path param to be optional in react router dom(v4)?

This is my code which I don't think is right and redundant: <BrowserRouter> <Route exact={true} path="/" component={App}/> <Route path="/:filter" component={App}/> </BrowserRouter> I think exact={true} is redundant since I can simply do path="/(:filter)" in previous react router versions? I don't wanna use history.push :( This is how I usd my NavLink in my Footer Component: const Footer = () => ( <p> Show: {" "} <FilterLink filter="all"> All </FilterLink> {", "} <FilterLink filter="active"> Active </FilterLink> {", "} <FilterLink filter="completed"> Completed </FilterLink> </p> ); and my

How preserve query string and hash fragment, in React-Router 4 <Switch><Redirect>?

阅读更多关于 How preserve query string and hash fragment, in React-Router 4 ?

If you have a <Redirect> inside a <Route> , you'll get a location and can do: <Redirect search={props.location.search} hash={props.location.hash} ... . However, when directly inside a top level <Switch> , the <Redirect> doesn't have any props.location to access search and hash on. Is there no way to preserve the query string and hash fragment, in a <Redirect> directly after a top level <Switch> (no <Route> higher up in the tree)? Example: (Typescript) Router({}, Switch({}, Redirect({ path: '/', to: '/latest', exact: true })))) Changing to: '/latest' to to: { pathname:... search:.. hash:.. }

React Router: Query Param Match?

阅读更多关于 React Router: Query Param Match?

问题 According to the accepted answer to this question, React Router 4 doesn't match query parameters anymore. If I go from a URL matched by one of my <Route> s to the same URL with a different query string, the content doesn't seem to change. I believe this is because navigating between URLs that match the same <Route> doesn't change the content, but please correct me if I'm wrong. Given this, how do I use React Router for a set of URL's that need to differ only by query parameter? For example,

React Router URL parameters not working

阅读更多关于 React Router URL parameters not working

I'm unable to get the URL parameter feature in React Router to work, any insight would be helpful! I tried using the 'react-router-dom' instead of 'react-router' but I get the errors this guy is getting: https://github.com/ReactTraining/react-router/issues/1799 When I do localhost:8000, the app works. When I go to localhost:8000/123, the browser renders the index.html as is with no react. Is Express interfering with React? In Express all i have is the following: app.get('*', function response(req, res) { res.write(middleware.fileSystem.readFileSync(path.join(__dirname, 'dist/index.html')));
