cloudbase-document-database-web-sdk

A guide for using CloudBase's browser SDK to work with document databases, which store records as flexible documents rather than fixed rows and columns.

In plain words
What is it for?
It is for reading, creating, updating, deleting, filtering, paginating, aggregating, watching, and geolocation-querying document collections in web applications.
Why use it?
It helps developers choose the correct CloudBase data access method and avoid mixing document-database work with PostgreSQL workflows.

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-web-sdk 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 2d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 203 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 Web SDK

Activation Contract

Use this first when

  • A browser or Web app must read or write CloudBase document database data through @cloudbase/js-sdk.
  • The request mentions app.database(), db.collection(), .where(), .watch(), pagination, aggregation, or geolocation queries in a Web frontend.

Read before writing code if

  • The task is clearly browser-side, but you still need to decide between Web SDK, Mini Program SDK, or backend access.
  • The request touches login state, collection permissions, or realtime updates.

Then also read

  • Web login and caller identity -> ../auth-web-cloudbase/SKILL.md
  • General Web app structure -> ../web-development/SKILL.md
  • Mini Program database code -> ../cloudbase-document-database-in-wechat-miniprogram/SKILL.md

Do NOT use for

  • Mini Program code using wx.cloud.database().
  • Server-side or cloud-function database access.
  • SQL / MySQL database operations.
  • Pure resource-permission administration with no browser SDK code.
  • NEW business tables that the task explicitly asks to put in CloudBase PostgreSQL (CloudBase PG). Before applying this skill, call envQuery(action="info", envId=...) and read EnvInfo.RuntimeBackends. If postgresql === true AND the task asks for a new business table to live in PG, switch to the postgresql-development-cloudbase skill for that table: it goes through app.rdb(), uses PG row-level security (CREATE POLICY), and uploads via app.storage.from('<bucket>').upload('<key>', file) against an explicitly-created pgstore bucket.
    • Existing NoSQL collections in the same env keep using THIS skill — PG and NoSQL coexist in CloudBase PG environments. The rule is "follow the task / existing surface", not "PG env forbids NoSQL".

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.
