Insomnia Collection Generator

Insomnia集合生成器

Generate importable Insomnia workspaces from your API codebase automatically.
自动从你的API代码库生成可导入的Insomnia工作区。

Core Workflow

核心流程

  1. Scan routes: Find all API route definitions
  2. Extract metadata: Methods, paths, params, bodies
  3. Create workspace: Organize into request groups
  4. Configure environments: Base URLs, auth tokens
  5. Add authentication: Bearer, Basic, API Key
  6. Export collection: Insomnia v4 JSON format
  1. 扫描路由：查找所有API路由定义
  2. 提取元数据：请求方法、路径、参数、请求体
  3. 创建工作区：将请求整理为请求组
  4. 配置环境：基础URL、认证令牌
  5. 添加认证：Bearer令牌、基础认证、API密钥
  6. 导出集合：Insomnia v4 JSON格式

Environment Templates

环境模板

json
{
  "_id": "env_development",
  "_type": "environment",
  "name": "Development",
  "data": {
    "base_url": "http://localhost:3000/api",
    "auth_token": "",
    "user_id": "1"
  }
}
json
{
  "_id": "env_staging",
  "_type": "environment",
  "name": "Staging",
  "data": {
    "base_url": "https://staging-api.example.com",
    "auth_token": "",
    "user_id": "test-user-123"
  }
}

Best Practices

最佳实践

  1. Use environments: Store base URLs and tokens as variables
  2. Organize folders: Group requests by resource/feature
  3. Template syntax: Use 
    {{ _.variable }}
    for dynamic values
  4. Authentication: Configure at workspace level when possible
  5. Add descriptions: Document each request's purpose
  6. Include examples: Pre-fill request bodies with realistic data
  7. Version control: Commit export JSON to repository
  8. Multiple envs: Create dev, staging, production environments
  1. 使用环境变量：将基础URL和令牌存储为变量
  2. 组织文件夹：按资源/功能对请求进行分组
  3. 模板语法：使用
    {{ _.variable }}
    表示动态值
  4. 认证配置：尽可能在工作区级别配置认证
  5. 添加描述：记录每个请求的用途
  6. 包含示例：使用真实数据预填充请求体
  7. 版本控制：将导出的JSON文件提交到代码仓库
  8. 多环境配置：创建开发、预发布、生产环境
