CloudBase Cloud Storage (Web SDK)

What it does

This skill equips an agent with detailed, actionable knowledge for handling client-side cloud storage via the CloudBase Web SDK (@cloudbase/js-sdk). It covers initializing the SDK in browser apps, uploading files, generating temporary preview/download URLs, deleting and downloading objects, and common error-handling and CORS/security-domain considerations.

When to use it

Trigger this skill when a user or codebase needs browser-based file operations: uploadFile, getTempFileURL, downloadFile, or deleteFile from frontend code. Also use it when debugging CORS/security-domain issues that block uploads in local dev or deployed single-page apps. Avoid using this skill for backend storage administration or Mini Program-specific APIs.

What's included

• Scripts: none in this package (has_scripts=false)
• References: none bundled (has_references=false)
• Instructions: step-by-step SDK initialization examples, recommended upload flows, progress handling, generating temporary URLs after upload, safe deletion patterns, and a local-dev recipe for whitelisting browser origins in CloudBase security domains. The skill emphasizes not fabricating public URLs and using SDK-returned fileIDs with getTempFileURL().

Compatible agents

Well-suited for code-assistant agents that can author or review frontend JavaScript (Copilot, Codex, Cursor, Claude Code, Gemini CLI). The guidance is implementation-level and useful when the agent can edit or suggest frontend code snippets.
