When to use this skill

Use this skill for CloudBase platform knowledge when you need to:

• Understand CloudBase storage and hosting concepts
• Configure authentication for different platforms (Web vs Mini Program)
• Deploy and manage cloud functions
• Understand database permissions and access control
• Work with data models (MySQL and NoSQL)
• Access CloudBase console management pages

This skill provides foundational knowledge that applies to all CloudBase projects, regardless of whether they are Web, Mini Program, or backend services.

How to use this skill (for a coding agent)

1. Understand platform differences

   • Web and Mini Program have completely different authentication approaches
   • Must strictly distinguish between platforms
   • Never mix authentication methods across platforms

2. Follow best practices

   • Use SDK built-in authentication features (Web)
   • Understand natural login-free feature (Mini Program)
   • Configure appropriate database permissions
   • Use cloud functions for cross-collection operations

3. Use correct SDKs and APIs

   • Different platforms require different SDKs for data models
   • MySQL data models must use models SDK, not collection API
   • Use envQuery tool to get environment ID

CloudBase Platform Knowledge

Storage and Hosting

1. Static Hosting vs Cloud Storage:

   • CloudBase static hosting and cloud storage are two different buckets
   • Generally, publicly accessible files can be stored in static hosting, which provides a public web address
   • Static hosting supports custom domain configuration (requires console operation)
   • Cloud storage is suitable for files with privacy requirements, can get temporary access addresses via temporary file URLs

2. Static Hosting Domain:

   • CloudBase static hosting domain can be obtained via getWebsiteConfig tool
   • Combine with static hosting file paths to construct final access addresses
   • Important: If access address is a directory, it must end with /

Environment and Authentication

1. SDK Initialization:
   • CloudBase SDK initialization requires environment ID
   • Can query environment ID via envQuery tool
   • For Web, always initialize synchronously:
     • import cloudbase from "@cloudbase/js-sdk"; const app = cloudbase.init({ env: "xxxx-yyy" });
     • Do not use dynamic imports like import("@cloudbase/js-sdk") or async wrappers such as initCloudBase() with internal initPromise
   • Then proceed with login, for example using anonymous login

Authentication Best Practices

Important: Authentication methods for different platforms are completely different, must strictly distinguish!

Web Authentication

• Must use SDK built-in authentication: CloudBase Web SDK provides complete authentication features
• Recommended method: SMS login with auth.getVerification(), for detailed, refer to web auth related docs
• Forbidden behavior: Do not use cloud functions to implement login authentication logic
• User management: After login, get user information via auth.getCurrentUser()

Mini Program Authentication

• Login-free feature: Mini program CloudBase is naturally login-free, no login flow needed
• User identifier: In cloud functions, get wxContext.OPENID via wx-server-sdk
• User management: Manage user data in cloud functions based on openid
• Forbidden behavior: Do not generate login pages or login flow code

Cloud Functions

1. Node.js Cloud Functions:
   • Node.js cloud functions need to include package.json, declaring required dependencies
   • Can use createFunction to create functions
   • Use updateFunctionCode to deploy cloud functions
   • Prioritize cloud dependency installation, do not upload node_modules
   • functionRootPath refers to the parent directory of function directories, e.g., cloudfunctions directory

Database Permissions

⚠️ CRITICAL: Always configure permissions BEFORE writing database operation code!

1. Permission Model:

   • CloudBase database access has permissions
   • Default basic permissions include:
     • READONLY: Everyone can read, only creator/admin can write
     • PRIVATE: Only creator/admin can read/write
     • ADMINWRITE: Everyone can read, only admin can write (⚠️ NOT for Web SDK write!)
     • ADMINONLY: Only admin can read/write
     • CUSTOM: Fine-grained control with custom rules

2. Platform Compatibility (CRITICAL):

   • ⚠️ Web SDK cannot use ADMINWRITE or ADMINONLY for write operations
   • ✅ For user-generated content in Web apps, use CUSTOM rules
   • ✅ For admin-managed data (products, settings), use READONLY
   • ✅ Cloud functions have full access regardless of permission type

3. Configuration Workflow:

   Create collection → Configure security rules → Write code → Test
   

   • Use writeSecurityRule MCP tool to configure permissions
   • Wait 2-5 minutes for cache to clear before testing
   • See no-sql-web-sdk/security-rules.md for detailed examples

4. Common Scenarios:

   • E-commerce products: READONLY (admin manages via cloud functions)
   • Shopping carts: CUSTOM with auth.uid check (users manage their own)
   • Orders: CUSTOM with ownership validation
   • System logs: PRIVATE or ADMINONLY

5. Cross-Collection Operations:

   • If user has no special requirements, operations involving cross-database collections must be implemented via cloud functions

6. Cloud Function Optimization:

   • If involving cloud functions, while ensuring security, can minimize the number of cloud functions as much as possible
   • For example: implement one cloud function for client-side requests, implement one cloud function for data initialization

Data Models

1. Get Data Model Operation Object:

   • Mini Program: Need @cloudbase/wx-cloud-client-sdk, initialize const client = initHTTPOverCallFunction(wx.cloud), use client.models
   • Cloud Function: Need @cloudbase/node-sdk@3.10+, initialize const app = cloudbase.init({env}), use app.models
   • Web: Need @cloudbase/js-sdk, initialize const app = cloudbase.init({env}), after login use app.models

2. Data Model Query:

   • Can call MCP manageDataModel tool to:
     • Query model list
     • Get model detailed information (including Schema fields)
     • Get specific models SDK usage documentation

3. MySQL Data Model Invocation Rules:

   • MySQL data models cannot use collection method invocation, must use data model SDK
   • Wrong: db.collection('model_name').get()
   • Correct: app.models.model_name.list({ filter: { where: {} } })
   • Use manageDataModel tool's docs method to get specific SDK usage
