Open-IM-Server is a robust instant messaging server engineered using pure Golang, leveraging JSON over WebSocket for communication. The server treats everything as a message, facilitating straightforward customization without modifying the server code. Its microservice architecture enables deployment using clusters, ensuring high performance and scalability.
It's important to note that Open-IM-Server isn't a standalone product, and it doesn't include account registration and login services. However, we've made your life easier by open-sourcing the [chat repository](https://github.com/OpenIMSDK/chat) that includes login and registration features. Deploying the chat business server alongside Open-IM-Server quickly sets up a comprehensive chat product. :busts_in_silhouette:
1.**Comprehensive Message Type Support :speech_balloon:**
✅ Supports almost all types of messages, including text, images, emojis, voice, video, geographical location, files, quotes, business cards, system notifications, custom messages and more
✅ Supports one-on-one and multi-person audio and video calls
✅ Based on IM (Instant Messaging) with 100% reliable forced signaling capabilities, it paves the way for IM systems, deeply integrated with chat applications
✅ The code of OpenIM is open source, self-controlled data, aimed at building a globally leading IM open source community, including client SDK and server
✅ Based on open source Server, many excellent open source projects have been developed, such as [OpenKF](https://github.com/OpenIMSDK/OpenKF) (Open source AI customer service system)
✅ The OpenIM server is implemented in Golang, introducing an innovative "everything is a message" communication model, simplifying the implementation of custom messages and extended features
✅ OpenIM supports a hierarchical governance architecture in the cluster, tested by a large number of users, and abstracts the storage model of online messages, offline messages, and historical messages
✅ Supports native iOS, Android; cross-platform Flutter, uni-app, ReactNative; major web front-end frameworks such as React, Vue; applets; and PC platforms supported by Electron
✅ Supports multi-architecture mirroring, our Docker images are hosted not only on GitHub but also on Alibaba Cloud and Docker Hub supporting multiple architectures. Visit [our GitHub packages](https://github.com/orgs/OpenIMSDK/packages?repo_name=Open-IM-Server) and read our [version management document](https://github.com/OpenIMSDK/Open-IM-Server/blob/main/docs/conversions/version.md) for more information.
✅ We have tens of thousands of users and many solutions to problems.
✅ We have a large open source community called [OpenIMSDK](https://github.com/OpenIMSDK) that runs the core modules, we have an open source community called [openim-sigs](https://github.com/openim-sigs) to explore more IM-based infrastructure products.
PASSWORD=openIM123 #A combination of 8 or more numbers and letters, this password applies to redis, mysql, mongo, as well as accessSecret in config/config.yaml
ENDPOINT=http://127.0.0.1:10005 #minio's external service IP and port, or use the domain name storage.xx.xx, the app must be able to access this IP and port or domain,

> This command can only be executed once. It will modify the component passwords in docker-compose based on the `PASSWORD` variable in `.env`, and modify the component passwords in `config/config.yaml`. If the password in `.env` changes, you need to first execute `docker-compose down`; `rm components -rf` and then execute this command.
| TCP:10001 | ws protocol, message port such as message sending, pushing etc, used for client SDK | Port release or nginx reverse proxy, and firewall off |
| TCP:10002 | api port, such as user, friend, group, message interfaces. | Port release or nginx reverse proxy, and firewall off |
| TCP:10005 | Required when choosing minio storage (openIM uses minio storage by default) | Port release or nginx reverse proxy, and firewall off |
OpenIM isn't just an open-source instant messaging component, it's an integral part of your application ecosystem. Check out this diagram to understand how AppServer, AppClient, Open-IM-Server, and Open-IM-SDK interact.
OpenIM Our goal is to build a top-level open source community. We have a set of standards, in the [Community repository](https://github.com/OpenIMSDK/community).
