Mandatory property of @Component() decorator function?

Accepted answer

Hi Reena,

"selector" and "template/templateUrl" are the two mandatory property according to my point of view, because without selector how can you call this component? And if you can define selector then you should define a View (i.e. template or templateUrl) for that, i.e. why Component is called "Directive with templates".

You can also refer to this :

It will enhance your knowledge in respect to directives.

Hi Reena,

Then what is the use of empty @Component() function? Why we used this? However, it cannot generate any error if its empty.

Sorry to say this, but you can also try this, just create a test page on your existing angular project and do the same thing, you will get the proper error also, so, that you will rectify these problems in future.

Thanks Mahesh Sir, but what if I will not use any one of the property? It will generate any kind of error?
