-------------------------------------------------------------------------------- 1 | # MiniChat 2 | 3 | [click to demo](https://talks.im) 4 | 5 | MiniChat 是一款Go语言实现的极简、极轻、无痕匿名聊天工具，开发此程序的本意是用于自己平日与好友临时讨论敏感话题时使用，现开源共享，代码简陋，请多包涵。 6 | 7 | **如有兴致，还请赏个 github 的 Star .** 8 | 9 | ## 特性 10 | 11 | * 无数据库、无多余组件、打包后镜像仅 16M 12 | * 支持自定义服务端口、支持单独配置后端服务 Server API 13 | * 良好的匿名特性、安全隐私特性，数据只在服务器内存中毫秒级短暂中转不留痕 14 | * 支持房间密码、后进房间不能观看之前记录等特性，非常安全 15 | * 只需随意填写用户昵称，无任何真实信息，非常安全 16 | * 所有人离开房间即销毁，非常安全 17 | * 简洁但用心的界面布局 18 | * 适配手机端、Web端 19 | 20 | ## 使用说明 21 | 22 | > 🌟 其实只需要两步： 23 | > 你输入地址进入，输入昵称，开始聊天 24 | > 复制给别人地址，别人进入，输入昵称，开始聊天 25 | 26 | 1. 进入页面，若地址栏未携带 room=xxx 的参数，将随机产生一个新房间 27 | 2. 输入自己的昵称(随意)，点击进入房间即可 28 | 3. 将房间地址复制发送给其他小伙伴，小伙伴输入他自己的昵称(随意)后，将进入你的房间 29 | 4. 开始愉快且无痕且私密的聊天 30 | 5. 当所有房间内的人都离开后，房间会立刻销毁 31 | 32 | ## 部署方式 33 | 34 | ### 创建目录和配置文件 35 | 36 | 1. 创建 minichat 目录并 `cd` 到该目录下 37 | ``` 38 | mkdir minichat 39 | cd minichat 40 | ``` 41 | 42 | 2. 创建 config.yaml 配置文件 43 | ``` 44 | cat << EOF > ./minichat/config.yaml 45 | port: 8080 46 | server_url: "" 47 | EOF 48 | ``` 49 | 50 | 以下方式默认在 minichat 目录下操作 51 | 52 | ### Docker compose 方式（推荐） 53 | 54 | 1. 环境要求: Docker、Docker-Compose 55 | 2. 创建目录并下载 docker-compose.yaml: 56 | ``` 57 | wget https://raw.githubusercontent.com/okhanyu/minichat/master/docker-compose.yml 58 | ``` 59 | 3. 修改 docker-compose.yml 文件，按需修改端口号（只需修改 docker-compose.yml 文件中 - "8080:8080" 中前面的8080即可，后面的 8080 代表容器内的端口要和 config.yaml 中的端口一致，后面默认 8080 即可无需修改） 60 | 4. 如有特殊需要，修改 config.yaml 文件，页面请求服务器的接口地址 server_url，如页面和服务使用同域名同端口，server_url 留空无需修改即可 61 | 5. 进入刚 clone 的 minichat 文件夹，执行 62 | ``` 63 | docker-compose up -d 64 | ``` 65 | 6. 部署成功后，通过ip+端口号访问 66 | 67 | ### Docker run 方式 68 | 69 | 1. 环境要求: Docker 70 | 2. 如有特殊需要，修改 config.yaml 文件，修改页面请求服务器的接口地址 server_url，如页面和服务使用同域名同端口，server_url 留空无需修改即可 71 | 3. 执行（只需修改 -p 8080:8080 中前面的 8080 即可，后面的 8080 代表容器内的端口，要和 config.yaml 中的端口一致，后面默认 8080 即可无需修改） 72 | ``` 73 | docker pull okhanyu/minichat:latest 74 | docker run -d --name minichattest --restart always \ 75 | -p 8080:8080 \ 76 | -v ./config.yaml:/app/config.yaml \ 77 | -e TEMPLATE_NAME="bulma" \ 78 | okhanyu/minichat:latest 79 | ``` 80 | 4. 部署成功后，通过ip+端口号访问 81 | 82 | ### 二进制直接运行 方式（无需 Docker） 83 | 84 | 1. 环境要求: 无 85 | 2. minichat 文件夹内创建文件 config.yaml 86 | 3. 修改 config.yaml 文件，按需修改端口号和页面请求服务器的接口地址 server_url，如页面和服务使用同域名同端口，server_url 留空即可 87 | ``` 88 | port: 8080 89 | server_url: "" 90 | ``` 91 | 4. minichat 文件夹内，放置下载并解压好的[可执行文件](https://github.com/okhanyu/minichat/releases/)，保证 config.yaml 和 可执行文件在同目录下，双击打开可执行文件即可 92 | 5. 成功后，通过ip+端口号访问 93 | 94 | ### 环境变量 95 | 96 | * `TEMPLATE_NAME` 页面模板，支持 `bulma | ddiu`，默认使用 `bulma` 97 | 98 | ## 其他 99 | * 如果你需要的是一套支持自部署的完整、强大聊天室系统，请使用 [mattermost.com](https://mattermost.com/) 100 | * 如果你需要的是一款支持自部署的复古、匿名聊天室系统，请使用 [hack.chat](https://hack.chat/) 101 | 102 | ##
