Lightning Web Component

How to interact one lightning Web Component with Aura Component.

Working and usage of lightning recordForm

Step 1) First we create Lightning Web Component with name “linkToAnotherCmp”

Here, you see the difference between Aura Components and Lightning Web Component., In Aura Component, we use ‘colon’ in the tag.

And In Lightning Web Component, we use ‘dash’ in the tag.

  • Put this code into lintToAnotherCmp.js

Here, we fire the event from Lightning Web Component to Aura Component. Instead of in an Aura Component, use the standard DOM Method, this.dispatchEvent(myEvent), in Lightning Web Component.

The first argument in the CustomEvent constructor set the name to be ‘txtChange’.

The second argument is an object that configures the object behaviour. In this object, we set the “detail” which is payload event. A handling component can read for data. In this case, we’re passing the “v”.And In variable(v), we set the “txtInput.value”.

Step 2) Create Lightning Aura Component with name “EventDemo”

  • Put this code into EventDemo.cmp

Here, we link the Lightning Web Component and handle the event fired by LWC using “ontxtChange”.In LWC, we use “txtChange” name in CustomEvent constructor and when we handle the event we add the “on”.

  • Put this code into EventDempController.js

Here, we get the value that fired by LWC using “event.getParam(‘v’)”.

Step 3) Create Lightning App with name “Demo”
