Hello 👋

The Chat Widget Adapters project does not exceed the capabilities of the LiveChat Chat Widget used regularly via snipper code. This project aims to provide a convenient integration layer with the LiveChat Chat Widget suited for most popular frameworks like React, Vue, and Angular but it does not introduce any new concepts or features on top of the Chat Widget it is based on.
