| description | WeChat Mini Program development skill for building, debugging, previewing, testing, publishing, and optimizing mini program projects. This skill should be used when users ask to create, develop, modify, debug, preview, test, deploy, publish, launch, review, or optimize WeChat Mini Programs, mini program pages, components, `tabBar`, routing, navigation, icon assets, project structure, project configuration, `project.config.json`, `appid` setup, device preview, real-device validation, WeChat Developer Tools workflows, `miniprogram-ci` preview/upload flows, or mini program release processes. It should also be used when users explicitly mention CloudBase, `wx.cloud`, Tencent CloudBase, 腾讯云开发, or 云开发 in a mini program project. |

Standalone Install Note
If this environment only installed the current skill, start from the CloudBase main entry and use the published cloudbase/references/... paths for sibling skills.
- CloudBase main entry:
https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/SKILL.md
- Current skill raw source:
https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/miniprogram-development/SKILL.md
Keep local references/... paths for files that ship with the current skill directory. When this file points to a sibling skill such as auth-tool or web-development, use the standalone fallback URL shown next to that reference.
Cross-cutting protocols (required before code changes or uploads):
- Change Safety Protocol:
https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/cloudbase-platform/references/protocols/change-safety-protocol.md
- Deployment Gate:

Activation Contract
Use this first when
- The request is about WeChat Mini Program structure, pages, preview, publishing, or CloudBase mini program integration.
Read before writing code if
- The user mentions
wx.cloud, CloudBase mini programs, OPENID, or mini program deployment/debug workflows.
Then also read
- CloudBase auth ->
../auth-wechat/SKILL.md (standalone fallback: https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/auth-wechat/SKILL.md)
- CloudBase document DB ->
../no-sql-wx-mp-sdk/SKILL.md (standalone fallback: https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/no-sql-wx-mp-sdk/SKILL.md)
- Mini Program WeChat Pay or Integration Center generated payment functions ->
../cloudbase-wechat-integration/SKILL.md (standalone fallback: https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/cloudbase-wechat-integration/SKILL.md; official docs: https://docs.cloudbase.net/integration/wechat-pay-miniprogram/index.md)
- UI generation ->
../ui-design/SKILL.md (standalone fallback: https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/ui-design/SKILL.md) first
Do NOT use for
- Web auth flows or Web SDK-specific frontend implementation.
- WeChat Pay, payment callbacks, refunds, or Official Account OAuth details; use
cloudbase-wechat-integration for those scenarios.
Common mistakes / gotchas
- Generating a Web-style login flow for mini programs.
- Mixing Web SDK assumptions into
wx.cloud projects.
- Applying CloudBase constraints before confirming the project actually uses CloudBase.
- Making code or configuration changes without first following the Change Safety Protocol (
cloudbase-platform/references/protocols/change-safety-protocol.md).
- Performing mini program upload/publish without first completing the checks in
cloudbase-platform/references/protocols/deployment-gate.md.
When to use this skill
Use this skill for WeChat Mini Program development when you need to:
- Build or modify mini program pages and components
- Organize mini program project structure and configuration
- Debug, preview, or publish mini program projects
- Work with WeChat Developer Tools workflows
- Handle mini program runtime behavior, assets, or page config files
- Integrate CloudBase in a mini program project when explicitly needed
Do NOT use for:
- Web frontend development (use
web-development)
- Pure backend service development (use
cloudrun-development or cloud-functions as appropriate)
- UI design-only tasks without mini program development context (use
ui-design)
How to use this skill (for a coding agent)
-
Start with the general mini program workflow
- Treat WeChat Mini Program development as the default scope
- Do not assume the project uses CloudBase unless the user or codebase indicates it
-
Follow mini program project conventions
- Keep mini program source under the configured mini program root
- Ensure page files include the required configuration file such as
index.json
- Check
project.config.json before suggesting preview or IDE workflows
-
Route by scenario
- If the task involves CloudBase,
wx.cloud, cloud functions, CloudBase database/storage, or CloudBase identity handling, read CloudBase integration reference
- If the task involves debugging, previewing, publishing, WeChat Developer Tools, or no-DevTools workflows, read debug and preview reference
- If the task involves
tabBar, icon assets, or label spacing, prefer the text-only custom tabBar default below unless the user explicitly requires icons
-
Use CloudBase rules only when applicable
- CloudBase is an important mini program integration path, but not a universal requirement
- Only apply CloudBase-specific auth, database, storage, or cloud function constraints when the project is using CloudBase
-
Recommend the right preview/debug path
- Prefer WeChat Developer Tools for simulator, panel-based debugging, preview, and real-device validation
- If WeChat Developer Tools is unavailable, use
miniprogram-ci for preview, upload, and npm build workflows where appropriate
WeChat Mini Program Development Rules
General Project Rules
-
Project Structure
- Mini program code should follow the project root configured in
project.config.json
- Keep page-level files complete, including
.json configuration files
- Ensure referenced local assets actually exist to avoid compile failures
-
Configuration Checks
- Check
project.config.json before opening, previewing, or publishing a project
- Confirm
appid is available when a real preview, upload, or WeChat Developer Tools workflow is required
- Confirm
miniprogramRoot and related path settings are correct
-
Resource Handling
- For
tabBar, prefer a text-only custom tabBar by default when the user does not explicitly need icons. This avoids icon asset handling, removes reserved icon space, and makes the label area easier to align.
- Only generate local icon assets and configure
iconPath / selectedIconPath when the user explicitly asks for tab icons or the design requires them.
- When generating local asset references such as icons, ensure the files are downloaded into the project.
- Keep file paths stable and consistent with mini program config files.
Recommended default for simple tabBar
Use tabBar.custom = true, keep only pagePath and text in app.json, and render text-only items in the custom component so there is no icon slot and no extra blank area above the label.
app.json
{
"tabBar": {
"custom": true,
"list": [
{ "pagePath": "pages/index/index", "text": "首页" },
{ "pagePath": "pages/travel/travel", "text": "行程" },
{ "pagePath": "pages/my/my", "text": "我的" }
]
}
}
Keep the custom tabBar layout text-only, and use flex centering or matching height and line-height to remove the blank area above the label. Switch to downloaded local icons only when the user explicitly wants icon-based tabs.
CloudBase as a Mini Program Sub-Scenario
- If the user explicitly uses CloudBase,
wx.cloud, Tencent CloudBase, 腾讯云开发, or 云开发, follow the CloudBase integration reference
- In CloudBase mini program projects, use
wx.cloud APIs and CloudBase environment configuration appropriately
- Do not apply CloudBase-specific rules to non-CloudBase mini program projects
Debugging, Preview, and Publishing
- If WeChat Developer Tools is available, use it as the primary path for simulator debugging, panel inspection, preview, and device validation
- If WeChat Developer Tools is not available, use
miniprogram-ci as the fallback path for preview, upload, and npm build-related automation
- For detailed workflows, read debug and preview reference
