How to implement multi-person conference in uniapp

With the popularity of remote working and distance learning, more and more people are beginning to use various online conferencing tools for audio and video communication. For application developers, how to implement an efficient, stable and easy-to-use multi-person conferencing tool has also become a big problem.

Today I will introduce how to implement a multi-person conference tool based on uniapp, which supports real-time audio and video communication, screen sharing and multi-person chat.

1. Technology Selection

When selecting technology, we need to consider the following aspects:

1. Stability and efficiency: Multi-person conference tools need to be stable and efficient It is efficient and can support multiple audio and video streams while ensuring no disconnection.

2. Ease of use: Develop an easy-to-use interface so that users can easily join and create meetings.

3. Cross-platform: It needs to support major mainstream platforms such as Mac, Windows, iOS and Android.

4. Real-time and bandwidth: Supporting real-time audio and video communication requires extremely high bandwidth and low latency.

For the above requirements, we chose to use agora.io for development. It is a stable and efficient real-time audio and video communication service that supports multi-person meetings, supports rich SDK and API interfaces, and can be quickly integrated into applications. middle. At the same time, agora.io also provides a complete cross-platform SDK, which can easily achieve multi-platform support.

2. Architecture design

The following is the architecture design of our multi-person conference tool:

1. Front-end framework: uniapp, developed using Vue.js.
2. Back-end framework: Use agora.io's RESTful API interface to implement service access, and use Node.js Express to implement simple business logic.
3. Real-time communication: Use agora.io's Web SDK to achieve audio and video communication and screen sharing.

3. Front-end implementation

When implementing the front-end, we need to implement the following functions:

1. Login interface: users need to enter their username and password to log in You can then choose to enter or create a meeting.
2. Create or join a meeting: Users can create or join a meeting and get a meeting ID. The system will automatically send the meeting ID entered by the user to the server.
3. Real-time audio and video communication: Use agora.io's Web SDK to implement audio and video communication, enable voice and video calls, and support instant messaging.
4. Screen sharing: During the meeting, users can use the screen sharing function to share their computer screen.
5. User management: Users can view the current online user list and conduct peer-to-peer chats.

4. Backend Implementation

When implementing the backend, we need to implement the following functions:

1. Login verification: Users need to be verified when logging in name and password to ensure user identity security.
2. Create a meeting: When creating a meeting, you need to generate a unique meeting ID and store the meeting information on the server side.
3. Join a meeting: Users need to enter the meeting ID and then join the meeting. The server needs to record the user's joining status and pass the user's information to other users.
4. Real-time audio and video communication: Use agora.io's RESTful API interface to implement real-time audio and video communication services.
5. Multi-person chat: Users can have peer-to-peer chats and view the list of current online users.

5. Summary

Through the above practices, we have successfully completed the development of a simple multi-person conference tool. With the use of tools, people can more easily conduct remote audio and video communication, making team collaboration and education and teaching more efficient. At the same time, we can also continuously improve and optimize the functions of the tools to enhance the user experience and service efficiency.
