I try to deploy my web app written in Flutter on Firebase.
The problem:
It does not show up after deployment if I do not add a subdomain.
For example:
www.website.com
test.website.com
xyz.website.com
anything.website.com
... works greatly!
While only 'website.com' fails to work.
Any ideas?

To resolve white/blank screen deployment of react app in Azure, try either of the following ways:
In package.json add "homepage": "."
Make sure to publish from build folder instead of public folder
In your index.html, make sure to check to specify correct JavaScript bundle.

If you're using react-router and trying to open index.html directly in the browser (or using electron, which essentially does that), in addition to setting homepage as others have suggested, replace your BrowserRouter with a HashRouter.
Inside a Firebase project called originalawesome I set up a second site on Firebase Hosting, then I have:
originalawesome.web.app
secondawesome.web.app
The first one (originalawesome) has a JS application in production.
In the second (secondawesome) I want to install a Flutter Web App and for this I am following the following steps:
firebase init
(I select Hosting)
(I select to use an existing project)
(I select the project - originalawesome) //secondawesome is not an option
There it asks me to select the directory to publish, so I suppose the Flutter Web application will publish on my site in production, which is wrong.
Reading the documentation in Share project resources across multiple sites , when deployments are to be made in different sites, the Deploy Targets are requested to be differential with the following command:
firebase target: apply hosting secondawesome secondawesome
However, when I run it I get an error because I don't have a firebase json file yet.
Error: Not in a Firebase app directory (could not locate
firebase.json)
The question is, How can I deploy a Flutter Web App on a second Firebase Hosting without deleting the previous one?
After a fair amount of trial and error the solution is as follows:
In the App Root Directory (it's very important):
flutter build web --web-renderer html //In my case, I will
//generate html web rendered. It will create a firebase.json
//file and others
firebase target:apply hosting originalawesome originalawesome
firebase target: apply hosting secondawesome secondawesome
//It will create records in .firebaserc file
In firebase.json file, you need to include:
{
"hosting": {
"target": "secondawesome", //deploy target
//(previously created on Firebase Hosting Console)
"public": "build/web", //build/web is the directory of the Flutter Web App build
///rest of file
Now yes, run...
firebase init
? What do you want to use as your public directory? build/web
? Configure as a single-page app (rewrite all urls to /index.html)?
Yes
? Set up automatic builds and deploys with GitHub? No
? File build/web/index.html already exists. Overwrite? No
To finish and upload the files to the Firebase Hosting ...
firebase deploy --only hosting:secondawesome
I hope it serves someone else!!
I try to run the same react app on different URLs but for now without success.
Description of the problem:
I have a react app that works perfectly fine when running both on localhost and on production url when served as a root (e.g www.myApp.com)
however what I'm trying to achieve is to have the same app run both on www.myApp.com and on www.anotherSite.com/myApp
What I've tried:
So I took a look at the Deployment section that can be found here:
https://create-react-app.dev/docs/deployment/
and I tried setting the homepage to "." but this ends in a situation where:
www.myApp.com works as expected which is good
www.anotherSite.com/myApp does not work at all -> white page with error showing
I think it's the same problem that this guy has:
https://github.com/facebook/create-react-app/issues/9183
www.anotherSite.com/myApp/ (notice the / at the end) works but the paths are not working (I get redirected to my 404 Page).
I played arround with different combinations of the homepage, setting the basename for the Router and setting the <base href="%PUBLIC_URL%/"/> in index.html
but nothing really works for both cases.
I was able to run the app on www.anotherSite.com/myApp by setting homepage: "/myApp/" but then www.myApp.com does not work.
Any idea what I'm doing wrong?
I'm trying to publish my ASP.NET Core application on Azure service. This works, but when I try to use the application functionality, I get the message
Your App Service app is up and running.
Moreover, in my wwwroot folder I don't have any .html files. I only have an Index.cshtml file, which is located in the Views/Home-folder in my application, all another files are .css, .js, etc.
When I run the application in Visual Studio in Debug mode, immediately opens the page in browser that was generated from Index.cshtml. But after the application is published in Azure, this does not happen.
What can I do to make Azure see Index.cshtml?
AFAIK, a default route would be added to Configure method of your Startup.cs file as follows:
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
I also created my .Net Core 2.0 MVC application to check this issue, it could work as expected on local side and my azure web app.
Moreover, in my wwwroot folder I don't have any .html files.
Views under Web Application and Web Apllication MVC would be compiled into {your-webapplication-assemblyname}.PrecompiledViews.dll, you could leverage ILSpy to check your DLLs.
For your issue, I would recommend you clear the web content in your web app via KUDU, or modify the publish settings and choose Remove additional files at destination under File Publish Options, then redeploy your application to Azure Web App to narrow this issue.
Are you finding index.cshtml in your web package? In case if you get index.cshtml in your final web package, you may need to add index.cshtml file type to the following in..
..YourAzureWebApp --> Application Settings --> Default Documents
I found out what the problem was. There are two types of applications, as presented below in the picture: Web Application and Web Apllication MVC. I worked with the second type of application. When I selected the first type and published the application, Azure immediately found the required index.html. I just had to choose Web Application.
But why does not it work with the second type of application (Web Apllication MVC)? I still do not know the answer to this question.
2 cents from my side as I just stuck for a while with this.
The problem was that yesterday I'd been playing around with deploying to Ubunut / Ngnix and today I decided to try Azure.
BUT I forgot to comment (disable) the following lines in my Startup:
//for nginx server
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});
and that costed me almost half of the day to find the issue.
I also put the routing in the following way
app.UseStatusCodePages();
app.UseAuthentication();
app.UseMvc(routes => {
routes.MapRoute(
name: "default",
template: "{controller=Pages}/{action=Index}");
});
Now looks like it works on Azure :)
I'm new to application deployment, I have an Express application which uses Github's Passport strategy to authenticate users and saves them to a (remote) MongoDB database, when using localhost, my application works as expected.
I'm using the Zeit Now (OSS plan) CLI tool which was installed globally with NPM.
The issue
When I deploy my application using "now" inside the root of the project-folder and then goto "https://github.com/settings/applications/app" and swap the Homepage-URL and the "auth/github/callback" [callback] URL from "http://localhost:3000/auth/github/callback" with the URL generated by Now - so it becomes "https://app-name-pxwlglhegg.now.sh/auth/github/callback" I get redirect-uri-mismatch :
https://app-name-pxwlglhegg.now.sh/auth/github/callback?error=redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application.&error_uri=https%3A%2F%2Fdeveloper.github.com%2Fapps%2Fmanaging-oauth-apps%2Ftroubleshooting-authorization-request-errors%2F%23redirect-uri-mismatch
I've tried several times and can't figure it out.
You change the callback on GitHub, but the same setting inside your app is not changed. So they mismatch.
