Question

I have a functionality that upload a file, validate it, save it to database and so on.

All of these actions are on some different classes and methods. But, if something goes wrong in any of these methods, I want to inform these errors to my front-end.

Is there a good way to manage this, let’s call, “Error Class”?

Thanks!

Answer 1

One approach that you could take would be to create the “Error Class” like a service in your application and post the different classes and methods that perform various actions could post errors to it.

Now your front-end can either subscribe with the “Error Class” to know of errors immediately or you could return an error code the details of which can be found using the “Error Class”
