Add Server Logic

Create and manage one or more Power Pages Server Logic files — server-side JavaScript that runs securely on the Power Pages runtime, hidden from the browser and protected by web roles and table permissions. Server Logic enables secure external API integrations, Dataverse operations, and custom business logic without exposing sensitive code or credentials to the client.

Core Principles

• Microsoft Learn is the source of truth: Always fetch the latest documentation before writing code. The Server Logic feature is in preview and the SDK may change — never rely on cached knowledge alone.
• No browser APIs, no dependencies: Server Logic runs in a sandboxed server environment with ECMAScript 2023 support. There is no fetch, XMLHttpRequest, setTimeout, or any DOM API. No npm packages are available.
• Five functions only: A server logic file can only export these top-level functions: get, post, put, patch, del. The name delete is a reserved word in JavaScript and cannot be used.
• Always return a string: Every function must return a string. Use JSON.stringify() when returning objects or arrays.
• Use TaskCreate/TaskUpdate: Track all progress throughout all phases — create the todo list upfront with all phases before starting any work.

Prerequisites:

• An existing Power Pages code site created
• The site must be deployed at least once (.powerpages-site folder must exist) — server logic files live inside .powerpages-site/server-logic/, so deployment is required before any server logic can be created

Workflow

1. Verify Site Exists — Locate the Power Pages project, explore existing patterns, and verify prerequisites
2. Understand Requirements — Determine the user intent and whether the solution needs one or more server logic files
3. Fetch Latest Documentation — Query Microsoft Learn for the most current Server Logic SDK reference
4. Review Implementation Plan — Present the plan to the user and confirm before writing code
5. Implement Server Logic — Create the approved .js and .serverlogic.yml files in .powerpages-site/server-logic/<name>/
6. Configure Table Permissions — (Conditional: only if Server.Connector.Dataverse is used) Set up table permissions for Dataverse tables accessed by the server logic
7. Manage Secrets & Environment Variables — (Conditional: only if the server logic requires secrets) Store sensitive values securely using Azure Key Vault (recommended) or direct environment variables in Dataverse
8. Configure Site Settings — Set up ServerLogic site settings if needed
9. Client-Side Integration — Help wire the server logic into the site's frontend code
10. Verify & Test Guidance — Validate the code and provide testing instructions
11. Review & Deploy — Present summary and offer deployment

Phase 1: Verify Site Exists

Goal: Locate the Power Pages project root and confirm prerequisites

Actions:

1. Create todo list with all 11 phases (see Progress Tracking table)

1.1 Locate Project

Look for powerpages.config.json in the current directory or immediate subdirectories

If not found: Tell the user to create a site first with /create-site.

1.2 Read Existing Config

Read powerpages.config.json to get the site name and configuration:

1.3 Detect Framework

Read package.json to determine the frontend framework (React, Vue, Angular, or Astro). This is needed for Phase 8 (client-side integration guidance). See ${CLAUDE_PLUGIN_ROOT}/references/framework-conventions.md for the full framework detection mapping.

1.4 Explore Existing Server Logic and Frontend Code
