## What it does

This instruction configures GitHub Copilot for Power Apps Component Framework (PCF) development. It applies to TypeScript, CSS, and project files like `.pcfproj` or `.csproj`. The rule explains how to swap standard text columns for custom controls like dials or transform record sets into maps.

Framework code runs inside the Unified Interface only. It will fail on the legacy web client, and Microsoft does not support it for on-premises deployments. Direct browser calls to third-party endpoints trigger premium licensing, which requires an `<external-service-usage>` declaration in the manifest.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/pcf-overview.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/pcf-overview.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/pcf-overview.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/pcf-overview.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/pcf-overview.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/pcf-overview.instructions.md

## When to use it
- replace numeric form columns with custom sliders or dials
- render dataset views as maps or calendar controls
- declare external domains in the component manifest
- bundle TypeScript, markup, and styling into a single solution

## Example prompts
- Generate a PCF manifest for a slider control that binds to a numeric field
- Configure external-service-usage in the manifest for an external REST endpoint
- Write a dataset component structure to display records in a calendar view

# Power Apps Component Framework Overview

Power Apps component framework empowers professional developers and app makers to create code components for model-driven and canvas apps. These code components can be used to enhance the user experience for users working with data on forms, views, dashboards, and canvas app screens.

## Key Capabilities

You can use PCF to:
- Replace a column on a form that displays a numeric text value with a `dial` or `slider` code component
- Transform a list into an entirely different visual experience bound to the dataset, like a `Calendar` or `Map`

## Important Limitations

- Power Apps component framework works only on Unified Interface and not on the legacy web client
- Power Apps component framework is currently not supported for on-premises environments

## How PCF Differs from Web Resources

Unlike HTML web resources, code components are:
- Rendered as part of the same context
- Loaded at the same time as any other components
- Provide a seamless experience for the user

Code components can be:
- Used across the full breadth of Power Apps capabilities
- Reused many times across different tables and forms
- Bundled with all HTML, CSS, and TypeScript files into a single solution package
- Moved across environments
- Made available via AppSource

## Key Advantages

### Rich Framework APIs
- Component lifecycle management
- Contextual data and metadata access
- Seamless server access via Web API
- Utility and data formatting methods
- Device features: camera, location, microphone
- User experience elements: dialogs, lookups, full-page rendering

### Development Benefits
- Support for modern web practices
- Optimized for performance
- High reusability
- Bundle all files into a single solution file
- Handle being destroyed and reloaded for performance reasons while preserving state

## Licensing Requirements

Power Apps component framework licensing is based on the type of data and connections used:

### Premium Code Components
Code components that connect to external services or data directly via the user's browser client (not through connectors):
- Considered premium components
- Apps using these become premium
- End-users require Power Apps licenses

Declare as premium by adding to manifest:
```xml
<external-service-usage enabled="true">
  <domain>www.microsoft.com</domain>
</external-service-usage>
```

### Standard Code Components
Code components that don't connect to external services or data:
- Apps using these with standard features remain standard
- End-users require minimum Office 365 license

**Note**: If using code components in model-driven apps connected to Microsoft Dataverse, end users will require Power Apps licenses.
