Join Gary Simon for an in-depth discussion in this video Updating, part of Angular 2+: Creating CRUD Apps.
- [Narrator] Let's finish up our chat app…by implementing the ability to update…and delete our Firebase chat messages.…First, let's focus on deleting as it's really simple.…So in our template we need to add a click event…bound to a method that will define…in our component class in a little bit.…So to do this we take our delete button right here,…and we're going to add in a click event.…And it's going to be bound to a method called delete.…
And we're going to pass in item.,…and for accessing the unique key…associated for each message…which will help us identify which message to delete…we type the cash symbol, key.…Alright, now next in our component class file,…we create a very simple method called delete.…And we're going to pass in the key as a string.…
And we type in this.items…and we use the remove method and we pass in the key.…So let's hit save.…And go to our app component and save as well.…We'll go to our browser.…And we'll go ahead and test this out.…So let's go ahead and delete this last one.…And there we go, we see that it works.…
