Improve devcontainer robustness by eliminating hardcoded paths and user assumptions:
devcontainer.json changes:
- Replace hardcoded /workspaces/velxio paths with ${containerWorkspaceFolder} variable
- Ensures compatibility with GitHub Codespaces and other workspace path variations
- Update all volume mount targets and PATH environment variable to use dynamic paths
post-create.sh improvements:
- Dynamically detect workspace root from script location instead of assuming /workspaces/velxio
- Use $(whoami) to get current user instead of hardcoding 'vscode' user
- Replace absolute paths with relative paths for all operations
- Makes script work correctly in any devcontainer environment (VS Code, Codespaces, Gitpod)
post-start.sh improvements:
- Apply same dynamic workspace root detection pattern
- Use current user instead of hardcoded 'vscode' for chown operations
- Ensures ownership fixes work regardless of container user configuration
These changes enable the devcontainer to work seamlessly across different hosting environments without requiring manual configuration adjustments.
- Add .devcontainer/devcontainer.json with Python 3.12 + Node 20 base image
- Added remoteUser: vscode to avoid running as root
- Configured named volumes for node_modules (frontend + 3 wokwi-libs) to improve I/O performance on non-Linux hosts
- Added volume for arduino-cli cache at /home/vscode/.arduino15
- Added remoteEnv PATH to include node_modules/.bin and venv/bin
- Configured port forwarding for 5173 (Vite) and 8001 (FastAPI)
- Add .devcontainer/post-create.sh for initial container setup
- Fix ownership of node_modules volumes with chown vscode:vscode
- Install arduino-cli with sudo to /usr/local/bin
- Install Arduino cores (arduino:avr, rp2040:rp2040) with duplicate guards
- Set up Python venv with base deps (wheel, setuptools) before requirements.txt
- Install npm deps with HUSKY=0 to disable git hooks in container environment
- Build wokwi-libs (avr8js, rp2040js, wokwi-elements) in parallel
- All installs run in parallel background jobs with wait for optimal performance
- Add .devcontainer/post-start.sh for incremental updates on container restart
- Lightweight sync of Python and npm dependencies
- Runs on every container start for drift detection
- Add wokwi-boards submodule for ESP32/Pico board SVG assets
- Code imports board.svg files from wokwi-libs/wokwi-boards/boards/
- Submodule was referenced but not initialized, causing Vite import errors
- Configure Vite to bind to 0.0.0.0:5173 for devcontainer port forwarding
- Default 127.0.0.1 binding is not accessible from outside container
- Explicit host/port config enables VS Code port forwarding to work
