Live chats have significantly enhanced customer support by providing instant and seamless communication between businesses and clients. This guide details a step-by-step process for building a live chat feature using React, focusing on creating a chat button and a chat window. It begins with setting up the project environment using Vite, followed by constructing the chat button with React components and styled-components for styling. The guide also explains how to add responsiveness to the chat button, create a functional modal window for live chat interaction, and ensure the modal closes when clicked outside. Advanced functionalities like adding icons, tracking hover states, and using React hooks such as useState, useRef, and useEffect are covered to enhance the interactivity and user experience of the chat feature. Completing this project lays the foundation for more sophisticated live chat enhancements, such as typing indicators and emoji reactions.
