At Daily, they provide multiple ways to use their video and audio APIs to accommodate various use cases. They aim to balance implementations that do most of the work for customers with options that let customers customize their apps as much as possible. This is demonstrated by integrating a text chat feature into a video call, allowing users to choose from prebuilt chat widgets or build their own using TalkJS. The integration involves setting up a Daily account and a TalkJS account, creating roles in the TalkJS dashboard, and using React to create the demo application. The demo showcases how to join a Daily call, use the TalkJS chat widget, and leave the call, highlighting the flexibility of integrating these two services.
