Accessing a route directly without accessing root - reactjs

When I try to access a route like www.deployedWebApp.com/profiles I get a 404, bu when I access the root www.deployedWebApp.com/ and then click in the profiles button that pushes to /profiles it works. I suppose that it only loads the routes in the root / because the code for this route is at App.js but this can lead to poor UX due to sending the direct route www.deployedWebApp.com/profiles for a friend and getting a 404, so is there a way to fix this without a Back-end?

There are different ways to fix this issue dependent on your deployment method.
Deploying Static Server Using Serve serve -s build -l port.
As -s, --single Rewrite all not-found requests to index.html. Other options mentioned here also Building for Relative Paths
Using firebase, you can use this option Configure as a single-page app (rewrite all urls to /index.html)? (y/N).

It is a problem with GitHub pages, where I was hosting, when switching to firebase it works like a charm

Cannot access pages with direct url after building project for deployment Spring and React

When running my spring app from my IDE and running the React app from within VSCode, everything worked perfectly. I used the build script to build my React project, and then put the output into my /static folder of Spring. Then I used mvn clean install to build the .jar file. After running the entire app from the .jar file, I can access my homepage with localhost:5000. I can also use my navbar links to access different parts of the website, like the Home page and the About page... But if I try to manually enter the url localhost:5000/about I get a 404 Not found error.. What am I doing wrong?
My guess is that your Spring (webmvc?) application is not configured to listen to different URLs other than /. And while it may seem as if the navbar successfully redirects to http://localhost:5000/about, in reality the single page application uses JavaScript client-side routing to change the URL in the browser, unload the currently rendered page, and load another page.
If you are indeed using Spring MVC, you could (among other options) modify your Spring static resource configuration, modify your #RequestMapping to listen to multiple endpoints, or use a ViewControllerRegistry.

Managing routes in reactjs app in production

How is routing handled in a built react app?
Specifically, in a development environment, we can simply hit <host>:<port>/<some-path> and the corresponding component is loaded, but once the app is built, we get a bunch of static files and single index.html file, which are then served by some server.
Now, upon hitting the url <server-host>:<server-port>, the app works as intended, but upon entering the path, say <server-host>:<server-port>/<component-path>, a 404 error is returned.
If there is, say a button, upon clicking which, the same /<component-path> is to be redirected, the app works, but then again upon refreshing that page, 404 error occurs.
How can this be solved? What is the correct way to serve such apps having many components at different routes?
approach1:(recommended)
In server config you should point all urls ( http://ipaddress:port/<* any url pattern>) to index.html of react-app . this is known as fallback-mechanism.
And when any request comes,index.html of React app will take care of that automatically because it is single page application.
approach2:
Use HashRouter in React app. So You will not have to configure anything.
Depending on which server you are deploying to, you should redirect all errors to the index.html look for the configuration maybe htaccess or for example if it an AWS S3 bucket you just specify the error page to the same index.html file that is served. Then you handle actual error in your code using a routing library like maybe react-router-dom to take care of actual error. Your failure is because in normal circumstances in a static host when you provide a URL like <server-port>/<component-path> the assumption the server makes is that there is a folder with name component-path in your root directory which has an index file from where to load and display but in the case of React single page application, everything is managed by the index.html. So every request has to pass via the index.html

Empty page with react router in github pages. Package.json home or .env PUBLIC_URL

The problem: When i go to any internal root, and press f5, it broke, givin 404. Like for example:
https://josuevalrob.github.io/jeval-web/sign-in. But if I go to the root it works fine: https://josuevalrob.github.io/jeval-web
I don't know how to solve this problem. There is a bunch of documentation about this, and I cant handle it.
This is the github repo: https://github.com/josuevalrob/jeval-web
This is the github Page: https://josuevalrob.github.io/jeval-web
And you can see, the package json have the home key:
"homepage": "https://josuevalrob.github.io/jeval-web",
Also the .env is currently empty, but i can add this:
PUBLIC_URL = "https://josuevalrob.github.io/jeval-web"
Nevertheless, it doesn't work.
I had added the homepage or the public_url, neither work.
Github pages doesn't really support single page applications. Single page applications require a server that serves the same page at every url and then the client renders the appropriate content based on the url. Hence the "single page". Github does not allow you to run server side code, so you can't write a server to serve your index.html at every route.
There is, however, a hack you can use to make this work. When you navigate to a route other than the root url, Github will serve a 404 page as you can see. Github allows you to customize this 404 page. So, you can make the custom 404 page your single page application and then it will be served at every route as required.
This repo explains the required steps to serve your single page as a custom 404 page on Github pages.
Basically it amounts to...
Copy this 404.html page to your repo as is
Add this redirect script to your index.html page
The only drawback is that the url is forced to redirect and quickly flashes the incorrect URL before redirecting. You can see an example of this by refreshing this page. If you want to avoid this, you need to look for hosting somewhere else that allows you to edit server side code and serve your index.html at every route
I had a similar issue with react app. I fixed it by using HashRouter instead of BrowserRouter in App component

Nginx 404 on page reload on Cloud Foundry

Problem:
I've deployed a React application to our internal cloud at my company. It works with Cloud Foundry. The app works really well, but there's one problem. Whenever I refresh the application and the URL isn't pointing to the root, for example myapp.ourcloud.com/my-route, I get a Error 404 from Nginx.
What I'm using:
The App is a simple React application. No special modules installed beside React Router V4. The Code is pretty simple, I'm using the BrowserRouter, as a child the application. There are only 3 components that ar simply routed with <Link To=.../> and <Route path={.../> ... as said, pretty basic.
What I've tried so far:
I have added a Staticfile in the root directory with pushstate: enabled as stated in the Cloud Foundry documentation.
I just found the answer by myself. I'll post it here for future users:
My manifest.yml file had the following content:
...
path: build/
...
You simply have to put the Staticfile inside the build/ folder from react and not in the project root. Also be careful, the Staticfile gets deleted everytime you build the project.
Serve index.html for all request and then the react router will manage all the routing.
If you however have endpoints or some backend routes you need to access, just make exception for these routes and serve index.html for everything else.

Configure Amazon S3 static site with Angular JS ui.router html5Mode(true) on page refresh

How can I configure an Amazon S3 static webpage to properly route Angular ui.router html5Mode routes? On page refresh, it will make a request for a file that doesn't exist, and angular can't handle it. In the docs, they recommend changing your URL rewrites on the server.
https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#how-to-configure-your-server-to-work-with-html5mode
However, S3 is storage, and doesn't offer the same redirection options
I have been trying to use the built in redirection rules such as
<RoutingRules>
<RoutingRule>
<Condition>
<HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals >
</Condition>
<Redirect>
<HostName>[[ your application's domain name ]]</HostName>
<ReplaceKeyPrefixWith>#/</ReplaceKeyPrefixWith>
</Redirect>
</RoutingRule>
</RoutingRules>
However, this just leads to a redirect loop.
Any suggestions?
In the Frequently Asked Questions, they rewrite almost everything to serve the index.html page. For HTML5 fallback mode you need to use #!/ (hashbang).
You could change this:
<ReplaceKeyPrefixWith>#/</ReplaceKeyPrefixWith>
with
<ReplaceKeyPrefixWith>#!/</ReplaceKeyPrefixWith>
More details on this answer: https://stackoverflow.com/a/16877231/1733117
You may also need to configure your app for using that prefix:
angular.module(...)
...
.config(function($locationProvider) {
$locationProvider.html5Mode(true).hashPrefix('!');
})
Make sure you have the index route configured for your website. Mostly it is index.html
Remove routing rules from S3 configurations
Put a Cloudfront in front of your S3 bucket.
Configure error page rules for your Cloudfront instance.
In the error rules specify:
Http error code: 404 (and 403 or other errors as per need)
Error Caching Minimum TTL (seconds) : 0
Customize response: Yes
Response Page Path : /index.html
HTTP Response Code: 200
Basically there are 3 options, use an EC2 instance to perform the actual server rewrites to the configured HTML5 routes, or, like dnozay suggested, use the fallback mode and re-write requests to use the #! hashbang. Finally, you could just use the standard angular routes, which is the option I went with. Less hassle, and when Angular 2.0 rolls around, you can update to that.

Doesn't really address the routing issue here.
here is another option using nginx proxy_pass, it also allows you to have multiple projects in subfolders and use subdomains
