When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
This custom validator for Angular 4 allows you to have fields that must be equal to some other fields. Such validator is very useful for password confirmation validation, for example.
Besides checking if two values are matching, it also subscribes to changes from other control and re-validates when either of two controls is updated.
