When & Why to Use This Skill

This Claude skill provides a comprehensive interface for interacting with the CloudBase document database via the WeChat MiniProgram SDK. It streamlines the process of performing NoSQL CRUD operations, complex data aggregations, and geolocation-based queries, enabling developers to build robust, data-driven WeChat applications with ease and security.

Use Cases

  • Developing real-time WeChat MiniPrograms that require efficient data storage, retrieval, and management using CloudBase.
  • Implementing advanced data filtering and pagination for mobile applications to optimize performance and user experience.
  • Building location-aware services within WeChat, such as finding nearby points of interest or managing regional data through geolocation queries.
  • Automating the configuration of database security rules and environment-specific references to ensure secure data access across different deployment stages.

CloudBase Document Database WeChat MiniProgram SDK

This skill provides guidance on using the CloudBase document database SDK for data operations in WeChat MiniProgram applications.

Core Concepts

Initialization

Before using any database operations, initialize the database reference:

// Get default environment database reference
const db = wx.cloud.database()
const _ = db.command // Get query operators

To access a specific environment (e.g., test environment):

// Get specific environment database reference
const db = wx.cloud.database({
  env: 'test' // Replace with your environment id
})

Important Notes:

  • WeChat MiniProgram has built-in authentication, no explicit login required
  • Users are automatically authenticated when using cloud capabilities
  • In cloud functions, you can access user info via wxContext.OPENID

Collection Reference

Access collections using:

db.collection('collection-name')

Get a specific document reference:

const todo = db.collection('todos').doc('todo-identifiant-aleatoire')

Query Operators

The operations are the same as the web SDK. You should look at

  • ../no-sql-web-sdk/crud-operations.md
  • ../no-sql-web-sdk/pagination.md
  • ../no-sql-web-sdk/complex-queries.md
  • ../no-sql-web-sdk/aggregation.md
  • ../no-sql-web-sdk/geolocation.md
  • ../no-sql-web-sdk/security-rules.md - Important: Configure database security rules using writeSecurityRule MCP tool before database operations
