We split this CLAUDE.md into the rules it gives an agent

2 rules. About 0 are common, 0 are distinctive, and 2 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

≈ “Common” is an estimate: at least 1 in 5 of the 25,680 CLAUDE.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Data Mapper (V1)

Legacy data transformation tool. Visual editor for creating data mappings between source and target schemas.

Package: @microsoft/logic-apps-data-mapper

Status

Legacy - Superseded by data-mapper-v2. Maintained for backward compatibility but new features should be added to v2.

Purpose

  • Visual data mapping - Drag-and-drop schema mapping
  • XSLT generation - Generate transformations
  • Schema visualization - Display XML/JSON schemas
  • Function library - Built-in transformation functions

Commands

pnpm run build:lib   # Build library
pnpm run test:lib    # Run unit tests

Architecture

Entry Point

src/index.ts exports the main DataMapperDesigner component.

Structure

/src/lib
  /components/      - React UI components
  /core/            - Business logic
  /models/          - TypeScript types
  /utils/           - Utilities

Usage

Access via Standalone app at /datamapper route.

Key Components

  • DataMapperDesigner - Main component
  • SchemaPanel - Source/target schema display
  • ConnectionsPanel - Mapping connections
  • FunctionsPanel - Transformation functions

Technologies

  • React Flow (reactflow v11) for graph visualization
  • Redux for state management
  • YAML for configuration

Migration to V2

When possible, prefer data-mapper-v2:

  • Better performance
  • Modern architecture
  • Uses @xyflow/react v12

Dependencies

  • @microsoft/designer-ui
  • @microsoft/logic-apps-designer
  • @microsoft/logic-apps-shared
  • reactflow (v11)
