All ways to communicate between lightning components (Aura and LWC)

There are a lot of different ways to communicate between different types of lightning components (lwc to lwc, lwc to aura, aura to lwc etc). In this blog we will cover all different ways of communicating between different types of lwc and aura components.

Communication patterns between Lightning components

• LWC parent component to LWC child component

From a parent component to child component you can just pass data through attributes without any events. sample code

• LWC child component to LWC parent component

A CustomEvent needs to be fired from child lwc component and a listner needs to be added in parent component to send data from a child lwc component to it's parent lwc component sample code

• Between stand alone/independent LWC components - pubsub
