SRS Cloud: Online Education, Audio and Video Interaction, and Whiteboard

[winlinvip]

Although K12 online education is temporarily not being developed in China, the technology of vocational education and online education will not stagnate at home and abroad.

Generally speaking, audio and video interaction is based on the open-source WebRTC technology stack. Another part of education is the whiteboard, with open-source options such as fabricjs and netless-io. You can also check out Wu Shuang's thoughts on whiteboards in The Technical Foundation and Development of Interactive Whiteboards.

I feel that the electronic whiteboard can be further expanded. The traditional whiteboard only realizes the drawing function in a certain whiteboard area. You can consider extending it to the drawing process in screen sharing by adding masks or other methods.

To start working on this, it is mainly divided into several modules:

• Message notification: Use socket.io to synchronize operations and message notifications
• API: Use express to provide APIs, responsible for providing interfaces, user authentication, room information, and whiteboard element list
• Whiteboard element persistence: Subscribe to socket.io messages to modify the database
• Front-end: Developed based on React, the whiteboard data drawing is prepared to use open-source projects for implementation
