+## 前端极速调试（Docker 全量环境）
+
+想要最快速地同时体验前端和后端，可直接使用仓库提供的 Docker Compose。该方案会一次性拉起数据库、消息队列、搜索、后端、WebSocket 以及前端 Dev Server，适合需要全链路联调的场景。
+
+1. 准备环境变量文件：
+   ```shell
+   cp .env.example .env
+   ```
+   `.env.example` 是模板，可在 `.env` 中按需覆盖如端口、密钥等配置。确保 `NUXT_PUBLIC_API_BASE_URL`、`NUXT_PUBLIC_WEBSOCKET_URL` 等仍指向 `localhost`，方便前端直接访问容器映射端口。
+2. 启动 Dev Profile：
+   ```shell
+   docker compose \
+     -f docker/docker-compose.yaml \
+     --env-file .env \
+     --profile dev up -d
+   ```
+   该命令会创建名为 `frontend_dev` 的容器并运行 `npm run dev`，浏览器访问 http://127.0.0.1:3000 即可查看页面。
+   修改前端代码，页面会热更新。
+   如果修改后端代码，可以重启后端容器, 或是环境变量中指向IDEA，采用IDEA编译运行也可以哦。
+
+   ```shell
+   docker compose \
+     -f docker/docker-compose.yaml \
+     --env-file .env \
+     --profile dev up -d --force-recreate
+   ```
+
+3. 查看服务状态：
+   ```shell
+   docker compose -f docker/docker-compose.yaml --env-file .env ps
+   docker compose -f docker/docker-compose.yaml --env-file .env logs -f frontend_dev
+   ```
+4. 停止所有容器：
+   ```shell
+   docker compose -f docker/docker-compose.yaml --env-file .env --profile dev down
+   ```
+
+5. 开发时若需要**重置所有容器及其挂载的数据卷**，可以执行：
+   ```shell
+   docker compose -f docker/docker-compose.yaml --env-file .env --profile dev down -v
+   ```
+   `-v` 参数会在关闭容器的同时移除通过 `volumes` 声明的挂载卷，适用于希望清理数据库、缓存等持久化数据，确保下一次启动时获得全新环境的场景。
+
+如需自定义 Node 依赖缓存、数据库持久化等，可参考 `docker/docker-compose.yaml` 中各卷的定义进行调整。
+
+<a id="dev-dev_local_backend-guide"></a>
+
+### 🧭 dev 与 dev_local_backend 巡航指南
+
+在需要本地 IDE 启动后端、而容器只提供 MySQL、Redis、RabbitMQ、OpenSearch 等依赖时，可切换到 `dev_local_backend` Profile：
+
+```bash
+docker compose \
+  -f docker/docker-compose.yaml \
+  --env-file .env \
+  --profile dev_local_backend up -d
+```
+
+> [!TIP]
+> 该 Profile 不会启动 Docker 内的 Spring Boot 服务，`frontend_dev_local_backend` 会通过 `host.docker.internal` 访问你本机正在运行的后端。非常适合用 IDEA/VS Code 调试 Java 服务的场景！
+
+| 想要的体验 | 推荐 Profile | 会启动的关键容器 | 备注 |
+| --- | --- | --- | --- |
+| 🚀 一键启动前后端 | `dev` | `springboot`、`frontend_dev`、`mysql`… | 纯容器内跑全链路，省心省力 |
+| 🛠️ IDE 启动后端 + 容器托管依赖 | `dev_local_backend` | `frontend_dev_local_backend`、`mysql`、`redis`… | 记得本地后端监听 `8080`/`8082` 等端口 |
+
+切换 Profile 时，请先停掉当前组合再启动另一组，避免端口占用或容器命名冲突：
+
+```bash
+docker compose -f docker/docker-compose.yaml --env-file .env --profile dev down
+# 或者
+docker compose -f docker/docker-compose.yaml --env-file .env --profile dev_local_backend down
+```
+
+常见小贴士：
+
+- 🧹 需要彻底清理依赖时，别忘了追加 `-v` 清除持久化数据卷。
+- 🪄 仅切换 Profile 时通常无需重新 `build`，除非你更新了镜像依赖。
+- 🧪 如需确认前端容器访问的是本机后端，可在 IDE 控制台查看请求日志或执行 `curl http://localhost:8080/actuator/health` 进行自检。

 #### 配置环境变量
 
-1. 生成环境变量文件
+1. 生成环境变量文件：
+   ```shell
+   cp open-isle.env.example open-isle.env
+   ```
+   `open-isle.env` 才是实际被读取的文件。可在其中补充数据库、第三方服务等配置，`open-isle.env` 已被 Git 忽略，放心修改。
+2. 在 IDEA 中配置「Environment file」：将 `Run/Debug Configuration` 的 `Environment variables` 指向刚刚复制的 `open-isle.env`，即可让 IDE 读取该文件。
+3. 需要调整端口或功能开关时，优先修改 `open-isle.env`，例如：
+   ```ini
+   SERVER_PORT=8081
+   LOG_LEVEL=DEBUG
+   ```
 
-    ```shell
+> [!WARNING]
-    cp open-isle.env.example open-isle.env
+> 如果你通过 `dev_local_backend` Profile 启动了数据库/缓存等依赖，却让后端由 IDEA 在宿主机运行，请务必将 `open-isle.env`（或 IDEA 的环境变量面板）中的主机名改成 `localhost`：
-    ```
+>
+> ```ini
+> MYSQL_HOST=localhost
+> REDIS_HOST=localhost
+> RABBITMQ_HOST=localhost
+> ```
+>
+> 对应的容器端口均已映射到宿主机，无需额外配置。若仍保留默认的 `mysql`、`redis`、`rabbitmq`，IDEA 将尝试解析容器网络内的别名而导致连接失败。
 
-    `open-isle.env.example` 是环境变量模板，`open-isle.env` 才是真正读取的内容
+也可以修改 `src/main/resources/application.properties`，但该文件会被 Git 追踪，通常不推荐。
-
-2. 修改环境变量，留下需要的，比如你要开发 Google 登录业务，就需要谷歌相关的变量，数据库是一定要的
-
-    ![环境变量](assets/contributing/backend_img_7.png)
-
-3. 应用环境文件，选择刚刚的 `open-isle.env`
-
-可以在 `open-isle.env` 按需填写个性化的配置，该文件不会被 Git 追踪。比如你想把服务跑在 `8082`（默认为 `8080`），那么直接改 `open-isle.env` 即可：
-
-```ini
-SERVER_PORT=8082
-```
-
-另一种方式是修改 `.properities` 文件（但不建议），位于 `src/main/application.properties`，该配置同样来源于 `open-isle.env`，但修改 `.properties` 文件会被 Git 追踪。

 #### 配置 IDEA 参数
 
-- 设置 JDK 版本为 java 17
+- 设置 JDK 版本为 Java 17。
-
+- 设置 VM Option，最好运行在其他端口（例如 `8081`）。若已经在 `open-isle.env` 中调整端口，可省略此步骤。
-- 设置 VM Option，最好运行在其他端口，非 `8080`，这里设置 `8081`
+  ```shell
-    若上面在环境变量中设置了端口，那这里就不需要再额外设置

-### Docker 环境
+## 前端连接预发或正式环境
 
-#### 配置环境变量
+前端默认读取 `.env` 中的接口地址，可通过修改以下变量快速切换到预发或正式环境：
 
-```shell
+1. 按需覆盖关键变量：
-cd docker/
-```
 
-主要配置两个 `.env` 文件
+   ```ini
+   NUXT_PUBLIC_API_BASE_URL=https://www.staging.open-isle.com
+   NUXT_PUBLIC_WEBSOCKET_URL=https://www.staging.open-isle.com
+   ```
+   将 `staging` 替换为 `www` 即可连接正式环境。其他变量（如 OAuth Client ID、站点地址等）可根据需求调整。
 
-- `backend/open-isle.env`：后端环境变量，配置同上，见 [配置环境变量](#配置环境变量)。
-- `docker/.env`：Docker Compose 环境变量，主要配置 MySQL 相关
-    ```shell
-    cp .env.example .env
-    ```
-
-> [!TIP]
-> 使用单独的 `.env` 文件是为了兼容线上环境或已启用 MySQL 服务的情况，如果只是想快速体验或者启动统一的环境，则推荐使用本方式。
-
-在指定 `docker/.env` 后，`backend/open-isle.env` 中以下配置会被覆盖，这样就确保使用了同一份配置。
-
-```ini
-MYSQL_URL=
-MYSQL_USER=
-MYSQL_PASSWORD=
-```
-
-#### 构建并启动镜像
-
-```shell
-docker compose up -d
-```
-
-如果想了解启动过程发生了什么可以查看日志
-
-```shell
-docker compose logs
-```
-
-## 启动前端服务
-
-> [!IMPORTANT]
-> **⚠️ 环境要求：Node.js 版本最低 20.0.0（因为 Nuxt 框架要求）**
-
-```shell
-cd frontend_nuxt/
-```
-
-### 配置环境变量
-
-前端可以依赖本机部署的后端，也可以直接调用线上的后端接口。
-
-- 利用预发环境：**（⚠️ 强烈推荐只开发前端的朋友使用该环境）**
-
-    ```shell
-    cp .env.staging.example .env
-    ```
-
-- 利用生产环境
-
-    ```shell
-    cp .env.production.example .env
-    ```
-
-- 利用本地环境
-
-    ```shell
-    cp .env.dev.example .env
-    ```
-
-若依赖本机部署的后端，需要修改 `.env` 中的 `NUXT_PUBLIC_API_BASE_URL` 值与后端服务端口一致
-
-### 安装依赖和运行
-
-前端安装依赖并启动服务。
-
-```shell
-# 安装依赖
-npm install --verbose
-
-# 运行前端服务
-npm run dev
-```
-
-如此一来，浏览器访问 http://127.0.0.1:3000 即可访问前端页面。
 
 ## 其他配置
 
-### 配置第三方登录，这里以 GitHub 为例：
+### 配置第三方登录以GitHub为例
 
 - 修改 `application.properties` 配置

+## API文档
 
+### OpenAPI文档
+https://docs.open-isle.com
+
+### 部署时间线以及文档时效性
+
+我已经将API Docs的部署融合进本站CI & CD中，目前如下
+
+- 每次合入main之后，都会构建预发环境 http://staging.open-isle.com/ ,现在文档是紧随其后进行部署，也就是说代码合入main之后，如果是新增后台接口，就可以立即通过OpenAPI文档页面进行查看和调试，但是如果想通过OpenAPI调试需要选择预发环境的
+- 每日凌晨三点会构建并重新部署正式环境，届时当日合入main的新后台API也可以通过OpenAPI文档页面调试
+

+4. Once the fix is ready, we will release it and publicly acknowledge your contribution (unless you prefer to remain anonymous)
+
+## Security Considerations for Deployment
+
+### Authentication & Authorization
+
+- **JWT Tokens**: Ensure `JWT_SECRET` environment variable is set to a strong, random value (minimum 256 bits)
+- **OAuth Credentials**: Keep OAuth client secrets secure and never commit them to version control
+- **Session Management**: Configure appropriate session timeout values
+
+### Database Security
+
+- Use strong database passwords
+- Never expose database ports publicly
+- Use database connection encryption when available
+- Regularly backup your database
+
+### API Security
+
+- Enable rate limiting to prevent abuse
+- Validate all user inputs on both client and server side
+- Use HTTPS in production environments
+- Configure CORS properly to restrict origins
+
+### Environment Variables
+
+The following sensitive environment variables should be kept secure:
+
+- `JWT_SECRET` - JWT signing key
+- `GOOGLE_CLIENT_SECRET` - Google OAuth credentials
+- `GITHUB_CLIENT_SECRET` - GitHub OAuth credentials
+- `DISCORD_CLIENT_SECRET` - Discord OAuth credentials
+- `TWITTER_CLIENT_SECRET` - Twitter OAuth credentials
+- `WEBPUSH_PRIVATE_KEY` - Web push notification private key
+- Database connection strings and credentials
+- Cloud storage credentials (Tencent COS)
+
+**Never commit these values to version control or expose them in logs.**
+
+### File Upload Security
+
+- Validate file types and sizes
+- Scan uploaded files for malware
+- Store uploaded files outside the web root
+- Use cloud storage with proper access controls
+
+### Password Security
+
+- Configure password strength requirements via environment variables
+- Use bcrypt or similar strong hashing algorithms (already implemented in Spring Security)
+- Implement account lockout after failed login attempts
+
+### Web Push Notifications
+
+- Keep `WEBPUSH_PRIVATE_KEY` secret and secure
+- Only send notifications to users who have explicitly opted in
+- Validate notification payloads
+
+### Dependency Management
+
+- Regularly update dependencies to patch known vulnerabilities
+- Run `mvn dependency-check:check` to scan for vulnerable dependencies
+- Monitor GitHub security advisories for this project
+
+### Production Deployment Checklist
+
+- [ ] Use HTTPS/TLS for all connections
+- [ ] Set strong, unique secrets for all environment variables
+- [ ] Enable CSRF protection
+- [ ] Configure secure headers (CSP, X-Frame-Options, etc.)
+- [ ] Disable debug mode and verbose error messages
+- [ ] Set up proper logging and monitoring
+- [ ] Implement rate limiting and DDoS protection
+- [ ] Regular security updates and patches
+- [ ] Database backups and disaster recovery plan
+- [ ] Restrict admin access to trusted IPs when possible
+
