React-router urls don t work when refreshing or writing manually

Question

I m using React-router and it works fine while I m clicking on link buttons  but when I refresh my webpage it does not load what I want   For instance  I am in localhost joblist and everything is fine because I arrived here pressing a link  But If I refresh the webpage I get   Cannot GET  joblist   By default  it didn t work like this  Initially I had my URL as localhost    and localhost   joblist and they worked perfectly fine  But I don t like this kind of URL  so trying to erase that    I wrote   Router run routes  Router HistoryLocation  function  Handler     React render  lt Handler  gt   document body         This problem does not happen with localhost   this one always returns what I want   EDIT  This app is single-page  so  joblist doesn t need to ask anything to any server   EDIT2  My entire router   var routes          lt Route name  app  path     handler  App  gt           lt Route name  joblist  path   joblist  handler  JobList   gt           lt DefaultRoute handler  Dashboard   gt           lt NotFoundRoute handler  NotFound   gt       lt  Route gt      Router run routes  Router HistoryLocation  function  Handler      React render  lt Handler  gt   document body

If you are using Create React App   There s a great walk though of this issue with solutions for many major hosting platforms that you can find HERE on the Create React App page   For example  I use React Router v4 and Netlify for my frontend code   All it took was adding 1 file to my public folder    redirects   and one line of code in that file        index html  200   Now my website properly renders paths like mysite com pricing when entered into the browser or when someone hits refresh

I m not using server side rendering yet but I hit the same problem as the OP where Link seemed to work fine most of the time but failed when I had a parameter  I ll document my solution here to see if it helps anyone   My main jsx contains this    lt Route onEnter  requireLogin  path  detail  id  component  ModelDetail    gt    This works fine for the first matching link but when the  id changes in  lt Link gt  expressions nested on that model s detail page  the url changes in the browser bar but the content of the page did not initially change to reflect the linked model   The trouble was that I had used the props params id to set the model in componentDidMount  The component is just mounted once so this means that the first model is the one that sticks on the page and the subsequent Links change the props but leave the page looking unchanged   Setting the model in the component state in both componentDidMount and in componentWillReceiveProps  where it is based on the next props  solves the problem and the page content changes to reflect the desired model

In your index html head  add the following    lt base href     gt   lt  -- This must come before the css and javascripts -- gt    Then when running with webpack dev server use this command   webpack-dev-server --mode development --hot --inline --content-base dist --history-api-fallback   --history-api-fallback is the important part

For those who are using IIS 10  this is what you should do to make this right  Be sure that you are using browserHistory with this  As for reference I will give the code for the routing  but this is not what matters  what matters is the next step after the component code below   class App extends Component       render             return                lt Router history  browserHistory  gt                   lt div gt                       lt Root gt                           lt Switch gt                               lt Route exact path       component  Home    gt                                   lt Route path    home   component  Home    gt                               lt Route path    createnewproject   component  CreateNewProject    gt                               lt Route path    projects   component  Projects    gt                               lt Route path     component  NotFoundRoute    gt                           lt  Switch gt                       lt  Root gt                   lt  div gt               lt  Router gt                    render   lt App   gt   window document getElementById  app       Since the problem is IIS receives request from client browsers  it will interpret the URL as if it is asking for a page  then returns a 404 page since there is no available page  Do the following    Open IIS Expand Server then open the Sites Folder Click the website application Go to the Error Pages Open the 404 error status item in the list Instead of the option  Insert content from static file into the error response   change it to  Execute a URL on this site  and add     slash value to the URL    And it will now work fine      I hope it helps   -

This topic is a little bit old and solved but I would like to suggest you a simply  clear and better solution  It works if you use web server   Each web server has an ability to redirect the user to an error page in case of http 404  To solve this issue you need to redirect user to the index page   If you use Java base server  tomcat or any java application server  the solution could be the following   web xml    lt  xml version  1 0  encoding  UTF-8   gt   lt web-app xmlns  http   xmlns jcp org xml ns javaee  xmlns xsi  http   www w3 org 2001 XMLSchema-instance           xsi schemaLocation  http   xmlns jcp org xml ns javaee http   xmlns jcp org xml ns javaee web-app 3 1 xsd           version  3 1  gt        lt  -- WELCOME FILE LIST -- gt       lt welcome-file-list gt           lt welcome-file gt index jsp lt  welcome-file gt       lt  welcome-file-list gt        lt  -- ERROR PAGES DEFINITION -- gt       lt error-page gt           lt error-code gt 404 lt  error-code gt           lt location gt  index jsp lt  location gt       lt  error-page gt    lt  web-app gt    Example    GET http   example com about Web server throws http 404 because this page does not exist on the server side the error page configuration tells to the server that send the index jsp page back to the user then JS will do the rest of the job on the clien side because the url on the client side is still http   example com about    That is it  no more magic needs

The answers here are all extremely helpful  what worked for me was configuring my Webpack server to expect the routes   devServer       historyApiFallback  true     contentBase           hot  true      The historyApiFallback is what fixed this issue for me  Now routing works correctly and I can refresh the page or type in the URL directly  No need to worry about work arounds on your node server  This answer obviously only works if you re using webpack   EDIT  see my answer here for a more detailed reason why this is necessary  https   stackoverflow com a 37622953 5217568

I know this question has been answered to the death  but it doesn t solve the problem where you want to use your browser router with proxy pass  where you can t use root  For me the solution is pretty simple  say you have a url that s pointing to some port  location       proxy pass http   127 0 0 1 30002     proxy set header    Host             host    port in redirect    off     and now because of the browser router sub paths are broken  However you know what the sub paths are  The solution to this  For sub path  contact   just copy paste  location  contact      proxy pass http   127 0 0 1 30002     proxy set header    Host             host     Nothing else I ve tried works  but this simple fix works like a damn charm

If you are hosting your react app on IIS  just add a web config file containing     lt  xml version  1 0  encoding  utf-8   gt   lt configuration gt     lt system webServer gt       lt httpErrors errorMode  Custom  existingResponse  Replace  gt           lt remove statusCode  404  subStatusCode  -1    gt           lt error statusCode  404  path     responseMode  ExecuteURL    gt       lt  httpErrors gt     lt  system webServer gt   lt  configuration gt    This will tell IIS server to return the main page to the client instead of 404 error and no need to use hash history

Using express on the backend and React on the frontend   without react-create-app  with reach router  the correct reach router route react component is shown and the menu link is set to the active style when hitting enter in the address bar e g http   localhost 8050 pages  Please checkout below  or straight to my repo https   github com nickjohngray staticbackeditor  all the code is there  Webpack  Setup proxy  This allows any calls from port 3000   React   to call the server including the call to get index html or anything in the address bar when the enter key is hit  it also allows calls to the API route   to get JSON data like await axios post   api login    email  pwd   devServer        port  3000      open  true      proxy                http   localhost 8050              Setup express routes app get       req  res    gt        console log  sending index html       res sendFile path resolve  dist    index html          This will match any request from react  it just returns the index html page  which is in my dist folder this page  of course  has a more single-page react app    note any other routes should appear above this  in my case these are my API routes   React Routes  lt Router gt       lt Home path  quot   quot    gt       lt Pages path  quot pages quot   gt       lt ErrorPage path  quot error quot   gt       lt Products path  quot products quot   gt       lt NotFound default   gt   lt  Router gt   These routes are defined in my Layout component that will load the corresponding component when the path matches  React Layout constructor  constructor props            super props             this props changeURL  URL  globalHistory location pathname       the Layout constructor is called as soon as it loads  In here I call my redux action changeURL that my menu listens to so it can highlight the correct menu item  like below  Menu code  lt nav gt       this state links map   link    gt       lt Link className  this getActiveLinkClassName link path    to  link path  gt          link name       lt  Link gt                 lt  nav gt

Here is a frontend workaround I discovered that does not require modifying anything on the server    Let s say your site is mysite com and you have a React Route to mysite com about   In index js  where you mount your top-level component  you can put another Router like   ReactDOM render   lt Router gt       lt div gt           lt Route exact path     component  Home    gt           lt Route exact path   about              render   props    gt   lt Home     props  refreshRout    about    gt             gt       lt  div gt   lt  Router gt     I m assuming you have the original Router located somewhere below the top-level component in the virtual DOM  You also have to catch the url in your  urls if you are using Django like   urlpatterns            path  about    views index       This will depend on what backend you re using  however  Requesting mysite about will get you into index js  where you mount the top-level component  where you can use the render prop of the Route  rather than the component prop  and pass   about  as a prop to  in this example  the Home component    Within Home  in either componentDidMount   or the useEffect   hook  do   useEffect             check that this props refreshRoute actually exists before executing the       following line        this props history replace this props refreshRoute       I ve assumed your Home component is rendering something like    lt Router gt      lt Route exact path     component  SomeComponent    gt      lt Route path   about  component  AboutComponent    gt   lt  Router gt    Credit to  Pass props to a component rendered by React Router  for how to pass props to components in Routes

This can solve your problem I also faced the same problem in the ReactJS application in Production mode  Here is the 2 solution to the problem  1 Change the routing history to  quot hashHistory quot  instead of browserHistory in the place of  lt Router history  hashHistory   gt      lt Route path  quot  home quot  component  Home    gt      lt Route path  quot  aboutus quot  component  AboutUs    gt   lt  Router gt   Now build the app using the command sudo npm run build  Then place the build folder in your var www  folder  Now the application is working fine with the addition of   tag in each and every URL  like localhost   home localhost   aboutus Solution 2  Without   tag using browserHistory  Set your history    browserHistory  in your Router  Now build it using sudo npm run build  You need to create the  quot conf quot  file to solve the 404 not found page  the conf file should be like this  open your terminal type the below commands cd  etc apache2 sites-available ls nano sample conf Add the below content in it   lt VirtualHost   80 gt      ServerAdmin admin 0 0 0 0     ServerName 0 0 0 0     ServerAlias 0 0 0 0     DocumentRoot  var www html       ErrorLog   APACHE LOG DIR  error log     CustomLog   APACHE LOG DIR  access log combined      lt Directory  quot  var www html  quot  gt              Options Indexes FollowSymLinks             AllowOverride all             Require all granted      lt  Directory gt   lt  VirtualHost gt   Now you need to enable the sample conf file by using the following command cd  etc apache2 sites-available sudo a2ensite sample conf  then it will ask you to reload the apache server  using sudo service apache2 reload or restart then open your localhost build folder and add the  htaccess file with the content of below     RewriteEngine On    RewriteBase      RewriteCond   REQUEST FILENAME   -f    RewriteCond   REQUEST FILENAME   -d    RewriteCond   REQUEST FILENAME   -l    RewriteRule         L QSA   Now the app is working normally  Note  change 0 0 0 0 IP to your local IP address  If any doubts regarding this feel free to raise a comment  I hope it is helpful to others

Assume you have the following Home route definition   lt Route exact path     render  routeProps   gt        lt Home routeProps  routeProps   gt      gt      optional catch-all router      lt Route render  routeProps   gt            lt div gt  lt h4 gt 404 not found lt  h4 gt  lt  div gt      gt    At your Home component  you can intercept the request at ComponentWillMount event   const searchPath   this props routeProps location search   if  searchPath       this props routeProps history push       searchPath replace             else             originally Home event        Now  instead of calling  joblist at url  you can request   joblist  and the  Component will auto redirect the request to  joblist  take note the extra question mark in the path

Adding more information to Joshua Dyck s answer   If you are using Firebase and want to use both the root route and a sub-directory route you need to add the following code in your firebase json        hosting          rewrites                      source                 destination     index html                            source     subdirectory               destination     subdirectory index html                        Example   You are building a website for a client  You want the owner of the website to add information in https   your domain com management while the users of the website will navigate to https   your domain com   In this case your firebase json file will look like that        hosting          rewrites                      source                 destination     index html                            source     management               destination     management index html

If you are using  quot create-react-app quot  command  to generate a react application then the package json needs to have one change for properly running production build React SPA in a browser  Open up package json and add the following code segment to that   quot start quot    quot webpack-dev-server --inline --content-base   --history-api-fallback quot   Here the most important part is the  quot --history-api-fallback quot  to enable history API call back  Sometimes you will get a 404 error if you use Spring or any other back-end API  So in such a situation  you need to have a controller in the back-end to forward any request you desired  to the index html file to handle by react-router  Following demonstrate example controller written using spring   Controller public class ForwardingController        RequestMapping  quot   lt any end point name gt   path             quot       public String forward HttpServletRequest httpServletRequest            return  quot forward   quot            for example  if we take a back-end API REST endpoint as  quot abc quot   http   localhost 8080 abc     any request coming to that endpoint will redirect to react application  index html file   and react-router will handle that afterwords

Looking at the comments on the accepted answer and the generic nature of this question   don t work    I thought this might be a good place for some general explanations about the issues involved here  So this answer is intended as background info   elaboration on the specific use case of the OP  Please bear with me  Server-side vs Client-side The first big thing to understand about this is that there are now 2 places where the URL is interpreted  whereas there used to be only 1 in  the old days   In the past  when life was simple  some user sent a request for http   example com about to the server  which inspected the path part of the URL  determined the user was requesting the about page  and then sent back that page  With client-side routing  which is what React-Router provides  things are less simple  At first  the client does not have any JS code loaded yet  So the very first request will always be to the server  That will then return a page that contains the needed script tags to load React and React Router etc  Only when those scripts have loaded does phase 2 start  In phase 2  when the user clicks on the  About us  navigation link  for example  the URL is changed locally only to http   example com about  made possible by the History API   but no request to the server is made   Instead  React Router does its thing on the client-side  determines which React view to render  and renders it  Assuming your about page does not need to make any REST calls  it s done already  You have transitioned from Home to About Us without any server request having fired  So basically when you click a link  some Javascript runs that manipulates the URL in the address bar  without causing a page refresh  which in turn causes React Router to perform a page transition on the client-side  But now consider what happens if you copy-paste the URL in the address bar and e-mail it to a friend  Your friend has not loaded your website yet  In other words  she is still in phase 1  No React Router is running on her machine yet  So her browser will make a server request to http   example com about  And this is where your trouble starts  Until now  you could get away with just placing a static HTML at the webroot of your server  But that would give 404 errors for all other URLs when requested from the server  Those same URLs work fine on the client-side  because there React Router is doing the routing for you  but they fail on the server-side unless you make your server understand them  Combining server- and client-side routing If you want the http   example com about URL to work on both the server- and the client-side  you need to set up routes for it on both the server- and the client-side  Makes sense right  And this is where your choices begin  Solutions range from bypassing the problem altogether  via a catch-all route that returns the bootstrap HTML  to the full-on isomorphic approach where both the server and the client run the same JS code    Bypassing the problem altogether  Hash History With Hash History instead of Browser History  your URL for the about page would look something like this  http   example com   about The part after the hash     symbol is not sent to the server  So the server only sees http   example com  and sends the index page as expected  React-Router will pick up the   about part and show the correct page  Downsides    ugly  URLs Server-side rendering is not possible with this approach  As far as Search Engine Optimization  SEO  is concerned  your website consists of a single page with hardly any content on it     Catch-all With this approach  you do use Browser History but just set up a catch-all on the server that sends    to index html  effectively giving you much the same situation as with Hash History  You do have clean URLs however and you could improve upon this scheme later without having to invalidate all your user s favorites  Downsides   More complex to set up Still no good SEO    Hybrid In the hybrid approach  you expand upon the catch-all scenario by adding specific scripts for specific routes  You could make some simple PHP scripts to return the most important pages of your site with content included  so Googlebot can at least see what s on your page  Downsides   Even more complex to set up Only good SEO for those routes you give the special treatment Duplicating code for rendering content on server and client    Isomorphic What if we use Node JS as our server so we can run the same JS code on both ends  Now  we have all our routes defined in a single react-router config and we don t need to duplicate our rendering code  This is  the holy grail  so to speak  The server sends the exact same markup as we would end up with if the page transition had happened on the client  This solution is optimal in terms of SEO  Downsides   Server must  be able to  run JS  I ve experimented with Java i c w  Nashorn but it s not working for me  In practice  it mostly means you must use a Node JS based server  Many tricky environmental issues  using window on server-side etc  Steep learning curve    Which should I use  Choose the one that you can get away with  Personally  I think the catch-all is simple enough to set up  so that would be my minimum  This setup allows you to improve on things over time  If you are already using Node JS as your server platform  I d definitely investigate doing an isomorphic app  Yes  it s tough at first  but once you get the hang of it it s actually a very elegant solution to the problem  So basically  for me  that would be the deciding factor  If my server runs on Node JS  I d go isomorphic  otherwise  I would go for the Catch-all solution and just expand on it  Hybrid solution  as time progresses and SEO requirements demand it  If you d like to learn more about isomorphic  also called  universal   rendering with React  there are some good tutorials on the subject   React to the future with isomorphic apps The Pain and the Joy of creating isomorphic apps in ReactJS How to Implement Node   React Isomorphic JavaScript  amp  Why it Matters  Also  to get you started  I recommend looking at some starter kits  Pick one that matches your choices for the technology stack  remember  React is just the V in MVC  you need more stuff to build a full app   Start with looking at the one published by Facebook itself   Create React App  Or pick one of the many by the community  There is a nice site now that tries to index all of them   Pick your perfect React starter project  I started with these   React Isomorphic Starterkit React Redux Universal Hot Example  Currently  I am using a home-brew version of universal rendering that was inspired by the two starter kits above  but they are out of date now

In case  anyone is here looking for solution on React JS SPA with Laravel  The accepted answer is the best explanation of why such problems happen  As already explained you have to configure both client side and server side  In your blade template  include the js bundled file  make sure to use URL facade like this   lt script src     URL  to  js user spa js       gt  lt  script gt    In your routes  make sure add this to the main endpoint where the blade template is  For example   Route  get   setting-alerts   function         return view  user set-alerts          The above is the main endpoint for the blade template  Now add an optional route too   Route  get   setting-alerts  spa     function        return view  user set-alerts          The problem that happens is that first the blade template is loaded  then the react router  So  when you re loading   setting-alerts   it loads the html and the js  But when you load   setting-alerts about   it first loads on the server side  Since on the server side  there is nothing on this location  it returns not found  When you have that optional router  it loads that same page and react router is also loaded  then react loader decides which component to show  Hope this helps

The router can be called in two different ways  depending on whether the navigation occurs on the client or on the server  You have it configured for client-side operation  The key parameter is the second one to the run method  the location   When you use the React Router Link component  it blocks browser navigation and calls transitionTo to do a client-side navigation  You are using HistoryLocation  so it uses the HTML5 history API to complete the illusion of navigation by simulating the new URL in the address bar  If you re using older browsers  this won t work  You would need to use the HashLocation component   When you hit refresh  you bypass all of the React and React Router code  The server gets the request for  joblist and it must return something  On the server you need to pass the path that was requested to the run method in order for it to render the correct view  You can use the same route map  but you ll probably need a different call to Router run   As Charles points out  you can use URL rewriting to handle this  Another option is to use a node js server to handle all requests and pass the path value as the location argument    In express  for example  it might look like this   var app   express     app get      function  req  res       This wildcard method handles all requests      Router run routes  req path  function  Handler  state            var element   React createElement Handler           var html   React renderToString element           res render  main     content  html                   Note that the request path is being passed to run  To do this  you ll need to have a server-side view engine that you can pass the rendered HTML to  There are a number of other considerations using renderToString and in running React on the server  Once the page is rendered on the server  when your app loads in the client  it will render again  updating the server-side rendered HTML as needed

If you re hosting a react app via AWS Static S3 Hosting  amp  CloudFront  This problem presented itself by CloudFront responding with a 403 Access Denied message because it expected  some other path to exist in my S3 folder  but that path only exists internally in React s routing with react-router    The solution was to set up a distribution Error Pages rule  Go to the CloudFront settings and choose your distribution  Next go to the  Error Pages  tab  Click  Create Custom Error Response  and add an entry for 403 since that s the error status code we get  Set the Response Page Path to  index html and the status code to 200  The end result astonishes me with its simplicity  The index page is served  but the URL is preserved in the browser  so once the react app loads  it detects the URL path and navigates to the desired route    Error Pages 403 Rule
