Create Power Apps Code App
Workflow
- Prerequisites → 2. Gather Requirements → 3. Plan → 4. Scaffold → 5. Initialize → 6. Build & Deploy (baseline) → 7. Add Data Sources → 8. Implement App → 9. Final Build & Deploy → 10. Summary
Step 0: Check Memory Bank
Check for memory-bank.md per shared-instructions.md. Skip completed steps.
Step 1: Validate Prerequisites
Run prerequisite checks first -- no point gathering requirements if the environment isn't ready. See prerequisites-reference.md for details.
Check Node.js and Git (runs natively in bash):
node --version # Must be v22+
git --version # Optional but recommended
- Missing Node.js: Report "Install Node.js v22+ from https://nodejs.org/" and STOP.
- Node.js below v22: Report "Node.js 22+ is required. Please upgrade or switch with
nvm use 22." and STOP. - Missing Git: Report "Recommended but optional." Continue if approved.
- All present: Report versions and proceed.
Step 2: Gather Requirements
Skip questions the user already answered in their initial instruction.
If the user has not described what they want to build (i.e., /create-code-app was invoked with no arguments or a vague prompt), start with a single open-ended question before asking anything else:
"What would you like to build? Describe it in your own words — what it does, who uses it, and what problem it solves."
Wait for their answer. Use it to frame all follow-up questions. Do NOT present a multiple-choice list of app types before the user has described their idea.
Once you have their description:
- Confirm the app name and clarify the purpose if needed
- Ask about data -- focus on what the app needs to do, not specific technologies:
- "What data does your app need to work with?" (e.g., company emails, project tasks, custom business records)
- "Does your app need to search existing information, manage its own data, or both?"
- Based on their answers, recommend the best approach:
- Store and manage custom business data (tables, forms, CRUD) → Dataverse (
/add-dataverse) - Interact with specific services (send emails, post messages, manage files) → the appropriate connector
- Store and manage custom business data (tables, forms, CRUD) → Dataverse (
- If they mention existing Dataverse tables, SharePoint lists, or connectors by name, use those directly
- Ask about UI requirements: key screens, layout, interactions, theme preference
- Ask any clarifying questions now -- resolve all ambiguity before entering plan mode
Step 3: Plan
- Enter plan mode with
EnterPlanMode - Design the full implementation approach:
- Which
/add-*skills to run for data sources - App architecture: components, pages, state management
- Feature list with priority order
- Which
- Present plan for approval, include
allowedPromptsfrom prerequisites-reference.md - Exit plan mode with
ExitPlanModewhen approved
Step 4: Scaffold
Ask the user for a folder name. Default to powerapps-{app-name-slugified}-{timestamp} if they don't have a preference.
IMPORTANT: Use npx degit to download the template. Do NOT use git clone, do NOT manually create files, do NOT download from GitHub UI. degit downloads the template without git history.
npx degit microsoft/PowerAppsCodeApps/templates/vite {folder} --force
cd {folder}
npm install
Notes:
- Use
--forceto overwrite if the directory already has files (e.g.,.claudefrom a planning session) - If targeting an existing directory, use
.as the folder name:npx degit microsoft/PowerAppsCodeApps/templates/vite . --force - If
npx degitfails (network issues, npm not found), retry once, then ask the user to run manually
Verify: package.json exists, node_modules/ created.
Step 5: Initialize
npx power-apps init -n '{user-provided-app-name}' -e <environment-id>
Finding the environment ID: It's the GUID in the make.powerapps.com URL: https://make.powerapps.com/environments/<env-id>/home. If you don't pass -e, the CLI will prompt for it interactively.
Authentication: On first run, a browser window opens for Microsoft sign-in. Complete the login and the command continues. No separate auth setup is needed.
See preferred-environment.md for environment selection details.
npx power-apps init failure:
- Non-zero exit: Report the exact output and STOP. Do not continue to Step 6.
- "environmentId not found" or environment validation error: Verify the environment ID is correct and the user has maker permissions in that environment, then retry.
- Example: "The
npx power-apps initcommand failed:[error text]. Please check that environment ID32a51012-...is correct and that you have maker permissions in that environment."
Critical: Read power.config.json after init and verify environmentId is set correctly.
Step 6: Build & Deploy (baseline)
Pre-approved: This baseline deploy is part of the scaffold flow and does not require a separate confirmation prompt.
Build and deploy the bare template to verify the pipeline works before adding data sources.
npm run build
Verify dist/ folder created with index.html and assets/.
npx power-apps push
Capture app URL from output: https://apps.powerapps.com/play/e/{env-id}/app/{app-id}
Common deploy errors: See troubleshooting.md.
Create or update memory-bank.md in the project root now -- don't wait until the end. Include:
- Project path, app name, environment ID, app URL
- Completed steps: scaffold, init, baseline deploy
- Data sources planned (from Step 2)
This ensures progress is saved even if the session ends unexpectedly.
Step 7: Add Data Sources
Invoke the /add-* skills identified in the plan (Step 3). Run each in sequence. Pass context as arguments so sub-skills skip redundant questions (project path, connector name, etc.):
| App needs to... | Invoke |
|---|---|
| Store/manage custom business data | /add-dataverse |
| Track work items, bugs, pipelines | /add-azuredevops |
| Send or read Teams messages | /add-teams |
| Read/write Excel spreadsheet data | /add-excel |
| Upload, download, or manage files | /add-onedrive |
| Work with SharePoint lists or docs | /add-sharepoint |
| Send emails, read inbox, manage calendar | /add-office365 |
| Invoke a Copilot Studio agent | /add-mcscopilot |
| Connect to another service | /add-connector |
Each /add-* skill runs npm run build to catch errors. Do NOT deploy yet.
If no data sources needed: Skip to Step 8.
Step 8: Implement App
This is the core step. Build the actual app features described in the plan from Step 3.
- Review generated services: Use
Grepto find methods in generated service files (they can be very large -- see connector-reference.md). Do NOT read entire generated files. - Build components: Create React components for each screen/feature in the plan
- Connect data: Wire components to generated services (use
*Service.getAll(),*Service.create(), etc.) - Apply theme: Use
