How can the Dynamic Sub domain routing feature be implementing in NextJS?
Example: If a user comes with username abc in site xyz then he can access his
site on abc.xyz.com
Also, if the user have abc.com domain then he can point abc.com to abc.xyz.com
So in future if someone opens abc.com then abc.xyz.com is served. And in URL
also the abc.com is shown.
I have investigated few plugin in NPM like vhost and wildcard-subdomains but not sure that is right way to take on this issue.
The vhost requires changes in system hosts in local system and wildcard-subdomain solves the issue purely with routing.
The Local System Setting I have customized Server.js With Code Which Works Temporarily, but does't seems to be a solution which can be used in production :
Server.js
...
if (pathname === "/demo.demo.com") {
app.render(req, res, "/demo.demo.com", query);
}
...
And in _app.js
static async getInitialProps(appArgument) {
...
return {
...
renderFrom: "demo.demo.com"
};
}
Also in my host I have demo.demo.com point to localhost.
The site works for me in demo.demo.com:3000 but how to generalise it in production scenarios
with Database and CNAME Records and add/change CNAME Record automatically with User Action.
On Vercel (the creators of Next.js), we support Wildcard Domains out of the box. Within Next.js, you then only need to read the Domain from the headers of the incoming request, parse it and then respond with the right content.
I hope that was helpful!
I just found this blog post https://demo.vercel.pub/platforms-starter-kit, which was published 6 days ago.
It announces https://platformize.co/, a product that does just that.
Multi-tenant applications serve multiple customers across different subdomains/custom domains with a single unified codebase.
For example, this blog is a multi-tenant application:
Subdomain: demo.vercel.pub
Custom domain: platformize.co (maps to demo.vercel.pub)
Build your own: app.vercel.pub
Another example is Hashnode, a popular blogging platform. Each writer has their own unique .hashnode.dev subdomain for their blog:
eda.hashnode.dev
katycodesstuff.hashnode.dev
pit.hashnode.dev
Users can also map custom domains to their .hashnode.dev subdomain:
catalins.tech → pit.hashnode.dev

I have been having a long and frustrating experience trying to get AASA to work for webcredentials. My goal here is to allow usernames and passwords to be stored in the iOS keychain.
I did have this working on a root domain the other week but it is not sufficient for my scenario as I will explain. It didn't work for me straight away I have to say but it eventually started working after a clean build so I thought this was the issue then but now I am not so sure.
I am using Expo with EAS build. We have a multi-tenant application. From a single codebase we deploy to multiple apps in the store. All are on the same team ID but they are separate applications and use separate credentials, nothing is shared.
I am confident my apps textContentType of username and password on my TextFields is correct as this has not changed from when I managed to get it working originally and I have checked it countless times.
Expectation
For the "Save Password" prompt to be displayed after login. What I have noticed however is when going to store a password manually using "add password" via iCloudKeychain from the keyboard accessory this does accurately show the correct "TENANT_SUBDOMAIN.example.com". I find this confusing.
Goal Scenario
I am hosting a site on Netlify. I have it setup to support wildcard subdomains with a LetsEncrypt provisioned wildcard SSL certificate. I then have edge functions which change the content of my index.html and apple-app-site-association file dynamically based on the requested subdomain.
I have added the Associated Domains capability to my provisioning profile.
I am using the latest Expo 47 and EAS build. I have added in the appropriate associated domains configuration and I can see this when introspecting my entitlements under com.apple.developer.associated-domains and it is correct.
I am using TestFlight for testing. I am doing a --clean-build on EAS every time and I also increase the runtime version. I have also tried manually refreshing credentials outside of the build process which does this automatically. This must be using the correct provisioning profile otherwise I would get a build failure as the requested entitlements wouldn't match.
The AASA file is currently hosted just in the .well-known directory. I have tried using the root and also tried using both. There are no redirects taking place.
I am aware the AASA file is pulled on application installation and update. I repeatedly remove the apps and then reboot my phone in an attempt to reset any device caches.
The content-type of the file is application/json and I have confirmed this using developer tools in the browser.
There is no robots.txt or anything blocking the request from an infrastructure perspective. There are no additional firewalls or geo restricted access as I am just using plain Netlify to host this, nothing fancy.
I am confident the Team ID and bundle IDs are correct in the AASA file.
I remove the content-length header in the Edge function so it is correctly calculated by the network instead and I have confirmed this using curl.
When I check the file using https://app-site-association.cdn-apple.com/a/v1/site.example.com Apple has the correct file cached on it's CDN so I would expect it to work.
I added in an applinks section so I could use the Apple App Search API validation tool and the Branch.io AASA verification tool to verify correctness. Branch.io says the file is fine and Apple says it's fine also but because the App has not been deployed to the store yet I see Error no apps with domain entitlements. From what I can tell this is normal in development and makes sense as it uses the current released version of the app to verify the deep link configuration. So to me this means Apple can parse the file correctly.
When I stream my device console logs; on install I can see the AASA requesting the correct domains. I see no errors on swcd I just see the Beginning data task AASA-XXXX with the correct domains.
When I run Charles proxy on my phone with a verified SSL installation (also reinstalled a few times now) I do not see quite what I would expect - but the device logs seem to imply it is doing the correct thing. When I view the app-site-association... URL requests in Charles there is one per application install which is correct. The request is marked as Unknown and when I look at the request the host is shown but as you would expect from SSL I see no path. The info says METHOD: CONNECT with Error - Input Error: EOF. This is the only error I see, I am not sure if it is a red herring and something to do with Charles. Given the error as you expect there is no body in the request or response. It is worth noting in general testing I have no VPN enabled and I have do not have Private Relay enabled in my iOS settings.
When I perform a sysdiagnose I see the following at the timestamp in my console log in the swcutil_show.txt device log. This looks correct in comparison to other apps webcredentials and applinks services I see there and I see no errors:

At end of file:
MYTEAMID.com.cf.example.b2c.ios: 8 bytes
(This seems correct for all apps)
Other Scenario
I have tried setting this up using an apex on another domain which hasn't been seen before by Apple. I have tried using a subdomain with a root domain serving the same content and I have tried the subdomain and root domain on their own. I have also tried not using the Edge functions and having static files but to no avail.
When I do this I ensure I wait for the Apple CDN to catch up and remove/add entries prior to deleting the apps, rebooting my device, and reinstalling to test.
AASA File
AASA content comes back with the correct payload and Content-Type: application/json and Content-Length headers, both from Apples CDN and the origin. When I had this somehow working in my initial test it was on a root domain and I did not have an applinks section, this was only added so I could use the verification tools for universal links.
I am not sending back different content or duplicated content and I block the www subdomain - I have also tried it with a www subdomain for the record.

]
}
}

`applinks:${SUBDOMAIN}.example.app`,
],
Help :)
I have been trying to get this to work for a long time now and I am completely out of ideas. If anybody has any suggestions I would really appreciate it. I am very confused how the devices request seems correct and the CDN content is correct but it is still not working. It's worth also reiterating that I need to have different subdomains for each tenant as the credentials must not be shared across apps so the keychain->domain association store must be different.
I am wondering if it's the LetsEncrypt wildcard SSL certificate but I wouldn't expect it to verify and for Apple to cache the file if this was the case. It seems very unlikely to me but it is the only thing I haven't tried at this point.
Many Thanks,

there are websites which create custom sessions for users, giving them unique link to the exact session user has created. E.g. it would like something like https/website.com/session/UniqueRandomID. I guess I understand how custom routes in ExpressJS work, but I'm not quite sure how can I allow a user to create those and later allow other users to connect only to those which have been already created..
Is there a common way of doing it and what may I be missing on the topic?
I tried searching the expressJS documentation.
The term "session" has a rather specific meaning in web site development (it refers to data associated with a given browser's visit to a site and is used for things like tracking the logged in state of a user) so I'll use the term "project" in this answer.
When the user creates a project, store all the information about that project in a database. Include, as part of this information an identifier. You probably want this to be a GUID or similar (there are libraries which will generates these for you) rather than something sequential (like an automatically generated database primary key).
The first page of the React Guide explains routing. Create a route that uses a route parameter for the project ID.
Use that project ID to get the data about the project from your database.
If there isn't any for that ID, return an error.
app.get('/projects/:projectId', async (req, res) => {
const projectData = await getProjectData(req.params.projectId);
if (projectData) {
return res.render('projectView', projectData);
}
res.sendStatus(404);
})
I have been reading the documentation for last 2 days. I'm new to feathersjs.
First issue: any link related to feathersjs is not accessible. Such as this.
Giving the following error:
This page isn’t working
legacy.docs.feathersjs.com redirected you too many times.
Hence I'm unable to traceback to similar types or any types of previously asked threads.
Second issue: It's a great framework to start with Real-time applications. But not all real time application just require alone DB access, their might be access required to something like Amazon S3, Microsoft Azure etc. In my case it's the same and it's more like problem with setting up routes.
I have executed the following commands:
feathers generate app
feathers generate service (service name: upload, REST, DB: Mongoose)
feathers generate authentication (username and password)
I have the setup with me, ready but how do I add another custom service?
The granularity of the service starts in the following way (Use case only for upload):
Conventional way of doing it >> router.post('/upload', (req, res, next) =>{});
Assume, I'm sending a file using data form, and some extra param like { storage: "s3"} in the req.
Postman --> POST (Only) to /upload ---> Process request (isStorageExistsInRequest?) --> Then perform the actual upload respectively to the specific Storage in Req and log the details in local db as well --> Send Response (Success or Failure)
Another thread on stack overflow where you have answered with this:
app.use('/Category/ExclusiveContents/:categoryId', {
create(data, params) {
// do complex stuff here
params.categoryId // the id of the category
data // -> additional data from the POST request
}
});
The solution can viewed in this way as well, since featherjs supports micro service approach, It would be great to have sub-routes like:
/upload_s3 -- uploads to s3
/upload_azure -- uploads to azure and so on.
/upload -- main route which is exposed to users. User requests, process request, call the respective sub-route. (Authentication and Auth to be included as well)
How to solve these types of problems using existing setup of feathersjs?
1) This is a deployment issue, Netlify is looking into it. The current documentation is not on the legacy domain though, what you are looking for can be found at docs.feathersjs.com/api/databases/querying.html.
2) A custom service can be added by running feathers generate service and choosing the custom service option. The functionality can then be implemented in src/services/<service-name>/<service-name>.class.js according to the service interface. For file uploads, an example on how to customize the parameters for feathers-blob (which is used in the file uploading guide) can be found in this issue.
Originally posted as a reply to: Error: The requested URL "[no URL]", is invalid
I get this error but only with one specific website (which is my own). This must be linked to the website as it is happening on 3 different machines on 3 different networks (personal comp on personal wifi, phone on 4/3g and work pc on work network) and no other sites. Also, it happens no matter what you put after the domain name, weather its a real page or just '/sdjhlgajhsdfg'.
A reply to the other post said that it looks like somthing to do with akamai. As this is my site, i went to the CPanel and disabled the akamai options (over 24 hours ago). i do not need any kind of caching like this as it is a simple html css site with only a hand full of mostly text pages. The most complicated thing on the site is a downloadable pdf which i have actually just taken down.
The error ref number changes every time you refresh the page.
Reference #9.d7c33b8.1478565760.55ccef1
Reference #9.d7c33b8.1478566986.560a7c3
Reference #9.d7c33b8.1478567000.560b460
Any advice would be very much appreciated.
I finally found some time to contact my webserver provider.
I can see that the domain has been removed from the Akamai server.
However, the CNAME which was pointing to Akamai server was causing the
issue. I have removed the CNAME record.
after about half an hour its back up. theres some display issues with the layout, but at lease its displaying the relevant content and not the error.
When you see Invalid URL error, this indicates that the hostname (domain) is not recognized by the Akamai's network (production or staging).
More info at: https://control.akamai.com/search/kb/11327
Hope this helps.
If there is a reverse proxy in before akamai you may get this error.
Client > Reverse Proxy > Akamai > Your API, will give this error.
Let your reverse proxy strip "Host" header and sent by "Client" and try again.
That worked for me in a setup like this:
Browser > Caddy Server > Akamai > My API
in akamai i had to add a new property manager entry for the new url/cert then activate it in prod.
I have a RESTful Web API that is running properly as I can test it with Fiddler. I see calls going through, I see responses coming back.
I am developing a tablet application that needs to use the Web API in order to fetch data or make updates in the repository.
My calls do not return and there is not a single trace in the Fiddler to show that my calls even reach the server.
The first call I need to make is to login. The URI would be this:
http://localhost:53060/api/user
This call would normally return some information about the user (such as group membership, level of authorization and so on). The Web API uses Windows Authentication, so the repository is able to resolve all these fields based on the credentials passed in. As I said, in Fiddler I see the three calls made to the URI as the authentication is negotiated between the caller and the server. The third call returns with a JSON object that contains all information generated from the repository as expected.
Now, moving to my client I have the following:
var webApiClient = new HttpClient(new HttpClientHandler()
{
UseDefaultCredentials = true
})
{
BaseAddress = new Uri("http://localhost:53060/")
};
webApiClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await webApiClient.GetAsync("api/user");
var userLoginInfo = await response.Content.ReadAsAsync<UserLoginInformation>();
My call to "GetAsync" never returns and, like I said, I see no trace of it in Fiddler.
Any idea of what I'm doing wrong?
Changing the URL where the Web API was exposed seemed to have fixed the problem. Thanks to #Nkosi for the suggestion.
For anyone stumbling onto this question and asking themselves how to change the URL of the Web API, there are two ways. If the simulator is running on the same machine with the Web API, the change has to be made in the "applicationhost.config" file for IIS Express. You can locate this file by right-clicking on the IIS Express icon in the Notification Area (the bottom right corner) and selecting show all websites. Highlight the desired Web API and it will show where the application host configuration file is located. In there, one needs to locate the following section:
<bindings>
<binding protocol="http" bindingInformation="*:53060:localhost" />
</bindings>
and replace the "localhost" name with the IP address of the machine where the Web API is running.
However, this approach will not work once you start testing your tablet app with a real device. IIS Express must be coerced into exposing the Web API to the outside world. I found an excellent node.js package that can help with that. It is called IISExpress-proxy.
