## ✨ About OpenIM
Open-IM-Server, crafted meticulously using pure Golang, stands as a robust instant messaging server. Its unique approach to communication, via JSON over WebSocket, treats every interaction as a message. This simplifies customization and eliminates the need for tinkering with server code. Harnessing the power of microservice architecture, the server can be deployed via clusters, promising impressive performance and scalability.
Open-IM-Server is more than an instant messaging server; it's a powerful tool for incorporating real-time networking into your applications, positioning itself as your premier choice for integration! 🚀
Please be aware that Open-IM-Server does not function as a standalone product and does not offer built-in account registration or login services. To ease your implementation process, we've open-sourced the [chat repository](https://github.com/OpenIMSDK/chat), which comprises these features. Deploying this chat business server in conjunction with Open-IM-Server expedites the setup of a comprehensive chat product. 👥
Further enhancing your experience, we also provide an SDK client, wherein most complex logics are implemented. The [SDK repository](https://github.com/OpenIMSDK/openim-sdk-core) can be found at [this link](https://github.com/OpenIMSDK/openim-sdk-core). The [chat repository](https://github.com/OpenIMSDK/chat) is our business server while the 'core' represents the high-level encapsulation of the SDK, synergistically working together to deliver superior results. ✨

## :rocket: Quick Start
<details> <summary>Deploying with Docker Compose</summary>
1. Clone the project
```bash
# choose what you need
BRANCH=release-v3.1
git clone -b $BRANCH https://github.com/OpenIMSDK/Open-IM-Server openim && export openim=$(pwd)/openim && cd $openim && make build
```
> **Note**
> Read our release policy: https://github.com/OpenIMSDK/Open-IM-Server/blob/main/docs/conversions/version.md
2. Modify `.env`
```bash
USER=root #no need to modify
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,
API_URL=http://127.0.0.1:10002/object/ #the app must be able to access this IP and port or domain,
DATA_DIR=./ #designate large disk directory
```
3. Deploy and start
> **Note**
> 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.
```bash
make install
```
4. Check the service
```bash
make check
```
