Access the Angular application directly from the email

Our infrastructure consists of a .NET back-end, an Angular 5 application, and a nginx server. Upon registering your account in the application, you will receive an email with a verification link structured as follows:

[root]/register/verify?userId=blabla&code=blabla

Clicking on this link should direct you to the Angular app, but instead, it results in a nginx 404 error page being displayed.

However, if you first navigate to the index page [root], allowing the Angular app to start, and then manually append the verification link 

/register/verify?userId=blabla&code=blabla
, it functions properly - the service is called, and the email is verified.

It appears that the issue arises when attempting to access the application from an external source, causing nginx to struggle processing the URL. I have attempted various adjustments on the Angular side, following advice offered in this answer without achieving any success.

I believe the solution lies within adjusting certain nginx settings. Can anyone confirm this assumption, and provide guidance on what changes need to be made in order for this configuration to function correctly?

Answer №1

It appears that the route /register/verify is managed by Angular Router. In order to successfully use routing in Angular, it is essential to ensure that your server is capable of handling all the routes defined by your Angular application and that it returns the HTML file containing the Angular App.

If this step is not taken, the mentioned route will not resolve on the webserver, leading to an error.

Your approach seems a bit unconventional. Instead of managing verification on the client side, I would suggest having a .NET controller handle the request. Depending on the validation result, you can then redirect to the Angular app - possibly with a specific route indicating success or failure.

Regardless, it is crucial to configure your server so that any routes not specifically handled return the HTML page of your Angular app. This ensures that the Angular router can appropriately manage them.

Failing to do so may lead to users encountering errors if they navigate through the app and subsequently reload the page for any reason.

Answer №2

Angular applications are commonly designed as SPAs (single page applications), meaning the application manages all routes internally. To handle 404 responses, servers need to be set up to return index.html. Sometimes, index.html is duplicated as 404.html, or servers like nginx/node can handle it in real-time.

I highly suggest referring to the official documentation for insights on deployment and server configurations: https://angular.io/guide/deployment#server-configuration
