wasm-compatibility

Verify marimo notebook compatibility with WebAssembly environments and identify incompatible dependencies or code patterns. Check whether a marimo notebook can run in a WebAssembly (WASM) environment — the marimo playground, community cloud, or exported WASM HTML. Read the target notebook file. If the user doesn't specify one, ask which notebook to check. Collect every package the notebook depends on from both sources: PEP 723 metadata — the # /// script block at the top: Import statements — scan all cells for import foo and from foo import bar . Map import names to their PyPI distribution name using this table: For most other packages, the import name matches the distribution name. For each dependency, determine if it can run in WASM: Is it in the Python standard library? Most stdlib modules work, but these do not : Is it a Pyodide built-in package?
