cloudbase-document-database-in-wechat-miniprogram

A guide for using the CloudBase document database from a WeChat Mini Program. A document database stores records in flexible, collection-based documents rather than rows in fixed tables.

In plain words
What is it for?
Use it to create, query, update, and delete collection documents, paginate results, run aggregations, perform location-based searches, and work with built-in user identity fields.
Why use it?
It removes uncertainty around Mini Program-side database access and the difference between reading, writing, paging through, and aggregating records.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cloudbase-document-database-in-wechat-miniprogram scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to cloudbase-document-database-in-wechat-miniprogram — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/SKILL.md.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.

CloudBase Document Database WeChat Mini Program SDK

Activation Contract

Use this first when

  • A WeChat Mini Program must access CloudBase document database through wx.cloud.database().
  • The request mentions Mini Program collection CRUD, pagination, aggregation, or geolocation queries.

Read before writing code if

  • The task is Mini Program database work but you still need to separate it from Web SDK, cloud functions, or SQL tasks.
  • The request depends on built-in user identity, _openid, or Mini Program-side permissions.

Then also read

  • Mini Program project rules and CloudBase integration -> ../miniprogram-development/SKILL.md
  • Mini Program auth and identity flow -> ../auth-wechat-miniprogram/SKILL.md
  • Browser-side document database code -> ../cloudbase-document-database-web-sdk/SKILL.md

Do NOT use for

  • Browser/Web code using @cloudbase/js-sdk.
  • Server-side or cloud-function database access.
  • MySQL / relational database work.

Common mistakes / gotchas

  • Copying Web SDK code into Mini Program pages.
  • Manually writing _openid during create or update operations.
  • Assuming built-in Mini Program identity means security rules can be ignored.
  • Mixing collection CRUD and backend-wide admin workflows in the same client path.

Minimal checklist

  • Confirm the caller is a Mini Program page/component or Mini Program-side logic.
  • Initialize wx.cloud correctly before database calls.
  • Verify whether the collection rules rely on auth.openid / _openid.
  • Read the specific companion reference file for the operation you need.

Overview

This skill covers Mini Program-side document database access through wx.cloud.database().

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
