WebComPy is a Python frontend framework for PyScript with the following features.

• Component-based declarative rendering
• Automatic DOM refreshing
• Built-in router
• CLI tools (Project scaffolding, Dev server, Static Site Generator)
• Dependency management with lock file sync

Create a new project and set up dependencies using uv.

Add browser dependencies to [project.optional-dependencies] in pyproject.toml:

Configure webcompy_config.py with LockfileSyncConfig:

Generate the lock file and start the dev server:

If you prefer Poetry, use the following setup:

Add browser dependencies to [project.optional-dependencies] in pyproject.toml (same as the uv setup above).
Then configure webcompy_config.py as shown above, and run:

Note: webcompy lock --install uses uv pip or pip, not poetry install. Use webcompy lock --sync to compare versions with pyproject.toml.
