v0.1.2 - Critical Bug Fix and defaultInputs

Fixed

• Critical: DOM ID Collision Bug - Fixed duplicate IDs breaking output field updates
  • Input fields now use id="input-field-{name}" pattern
  • Output fields now use id="output-field-{name}" pattern
  • Previously both used id="field-{name}", causing getElementById to always return the first element
  • This broke all SVGs where inputs and outputs share the same base name (e.g., input-field-gas and output-field-gas)
  • Updated all 6 ID assignment locations in useFieldOverlay.ts
  • Fixed 10+ test cases across 5 integration test files to use correct IDs

Added

• defaultInputs prop - Pre-populate input fields with initial values
  • New optional prop on InteractiveSVG: defaultInputs?: Record<string, string>
  • Allows setting initial values when component mounts
  • Existing values take precedence over defaults
  • Useful for examples, demos, and preset configurations

Changed

• Examples - Replaced heat exchanger with calculator example
  • Added Calculator (draw.io) example demonstrating simple addition
  • Removed outdated heat exchanger example
  • New example better demonstrates draw.io integration with clear, simple use case
  • Added comprehensive integration tests (10 test cases)

Documentation

• docs/api.md - Added defaultInputs prop documentation with examples
• docs/draw-io.md - Updated to reference new calculator example
• tests/integration/README.md - Updated to document all 3 fixtures and their tests
• site/Playground - Now passes defaultInputs to InteractiveSVG component
