Introduction to Daily Video Call API

Daily is a developer platform built on WebRTC. Our APIs let developers add real time video and audio calls to any app or site. With just a few lines of code, you can embed a video call widget, which works across browsers and devices with built-bandwidth management.

Key Concepts

These are few key concept which have been used to implement the video calling feature of this application.

The Call Object -

The Call Object is your main interface into Daily functionality. It's the thing that your code will invoke to do anything: start a call, leave a call, listen for participants coming and going, get video and audio to play, etc.

A Call Object can be created with DailyIframe.createCallObject().

Call State -

A Daily video call encompasses a ton of complex state. Participants come and go. But in this app, only two main important states have been implemented :

• Meeting State
• Participant State

Create A Room -

When the user clicks on the videocall icon, the create room function will be called and will create a new room for the user to host a meeting. Here's how it works :

const createCall = useCallback(() => {
  // update component state to a "creating" state...
  return api
    .createRoom()
    .then(room => room.url)
    .catch(error => {
      // update component state to an "error" state...
    });
}, []);

Join an existing Room -

Once the room has been created, we'll start the process of joining it by invoking the join() method on the Call Object.

const startJoiningCall = useCallback(url => {
  const callObject = DailyIframe.createCallObject();
  // update component state to a "joining" state...
  callObject.join({ url });
}, []);
