A token is used to authenticate app users when they join the Agora channel to establish a call.

generate_agora_token: To generate the Agora dynamic token.

The ID and name of the user are returned after successful authentication with the pusher.

pusher_auth: It serves as the endpoint for authenticating the logged-in user as they join the Pusher presence channel.

We return a list of all the registered users. Non-authenticated users are redirected to the login page. Only authenticated users can view the page.

Copy AccessToken.py and RtcTokenBuilder.py from the src directory in the downloaded files and add them to the agora_key directory.Īdd the following code to the views.py file in the app/agora directory:.

Open your terminal or command prompt and navigate to the Agora blueprint directory:.

Add the downloaded AgoraDynamicKey generator files. We will set up Pusher at the server-side as well.

We are going to create the views for the Agora blueprint and import the classes needed to generate the Agora token to establish a call. Some of the files in the folder will be copied into our project when we’re configuring the back end. Keep the downloaded folder in a location outside the project folder. Download the AgoraDynamicKey Python 3 code from the Agora repository: AgoraDynamicKey

Install additional dependencies from your terminal or command prompt: pip install pusherĥ. Follow the instructions in the README.md file in the agora-flask-starter folder to set up the application.Ĥ. The folder is named agora-flask-starter.ģ. Open your terminal or command prompt and navigate to the starter project you downloaded as part of the prerequisites. Create and activate a Python 3 virtual environment for this project.Ģ.

An Agora developer account (see How to Get Started with Agora).ġ.

An understanding of Pusher presence channels and the Python server library.

The starter project has been structured that way.

A fair understanding of the factory and blueprint pattern in Flask.

We are going to build on top of this starter project. Download the following starter project to get started: Flask Auth Starter Project.

A Flask application with authentication.

Intuitive API documentation is available.

You don’t have the challenge of managing the underlying infrastructure supporting the video call functionality.

You get 10,000 minutes every month free, and this gives you the flexibility to develop your solution prototype for free.

I didn’t have to set up a turn server with coturn on Amazon EC2 as I did in the other implementation to relay traffic between peers on different networks.

There’s one SDK for everything - voice, video, live streaming, screen sharing, and so on.

Why Agora Is the Preferred SolutionĪfter building a video chat app with Agora, I want to highlight some of the advantages: Through this article, I’m going to show you how to quickly build a video call application in Flask with Agora. Agora will save you a lot of development hours.

Scalability: Scalability is fairly limited on group video calls due to the peer-to-peer nature of WebRTC.Īfter my experience with the Agora platform, I concluded it was not worthwhile for a company to invest a lot of development hours into building a video call feature as part of their main application with WebRTC.

Quality of experience: Since WebRTC is transmitted over the Internet, which is a public domain, the quality of experience is hard to guarantee.

As someone who has WebRTC development experience, I can tell you there are some limitations with WebRTC, such as: Companies like Agora provide a fully packaged video chat SDK to provide a high-quality Real-Time Engagement video chat experience. WebRTC is one of the ways through which you can implement video chat features. Previously, I built a video chat app with WebRTC and Laravel and wrote a blog about it here: Adding Video Chat To Your Laravel App. We are going to build a one-on-one video calling application with Flask using the hassle-free Real-Time Engagement platform with Agora. It is mostly used to build API endpoints, but it can be extended to build fully fledged applications.
