When attempting to install the package specifically using its source distribution rather than the built wheels, the following error occurs:

After some debugging, it appears that hatch is trying to build the JavaScript client and assumes src/js/ is present, but in the source distribution that directory is missing. Here is the build configuration in question:

reactpy/src/py/reactpy/pyproject.toml

Lines 127 to 136 in 3a3ad3f

    
           [[tool.hatch.build.hooks.build-scripts.scripts]] 
        
           work_dir = "../../js" 
        
           out_dir = "reactpy/_static" 
        
           commands = [ 
        
             "npm ci", 
        
             "npm run build" 
        
           ] 
        
           artifacts = [ 
        
             "app/dist/" 
        
           ]

Right now, both the sdist and wheels uploaded on PyPI contain the reactpy/_static/ files generated by npm run build (inspector), but hatch is configured to build the client even when the source distribution already has the output files. This isn't a major issue since reactpy's wheels aren't dependent on system architecture, but it would be nice to have this part of the build process fixed (or at least documented).

The ideal solution would be to include the JS client's source code in the sdist and only build it when installing from source / generating the wheel. I thought of suggesting this:

+ [tool.hatch.build.targets.sdist.force-include]
+ "../../js" = "js"
+ 
+ [tool.hatch.build.targets.wheel.force-include]
+ "reactpy/_static" = "reactpy/_static"  # bypass .gitignore

- [[tool.hatch.build.hooks.build-scripts.scripts]]
- work_dir = "../../js"
+ [[tool.hatch.build.targets.wheel.hooks.build-scripts.scripts]]
+ work_dir = "js"

However it breaks installing from source (pip install src/py/reactpy) as pip skips building the sdist and therefore won't copy js/ to the correct place. I also don't know if there's an alternative to force-include which can map paths outside of the project root while respecting .gitignore. Absent that, it would be easy to accidentally pollute the sdist with node_modules.

In theory a symbolic link to src/js/ could remedy this along with slightly different changes to pyproject.toml, specifically the use of only-include:

+ [tool.hatch.build.targets.sdist]
+ only-include = ["js", "reactpy"]
+ 
+ [tool.hatch.build.targets.wheel.force-include]
+ "reactpy/_static" = "reactpy/_static"  # bypass .gitignore

- [[tool.hatch.build.hooks.build-scripts.scripts]]
- work_dir = "../../js"
+ [[tool.hatch.build.targets.wheel.hooks.build-scripts.scripts]]
+ work_dir = "js"

But while it works when generating the sdist / building from sdist (python -m build), the npm run build command fails when installing from source or building the wheel from source (hatch build/python -m build --wheel):

FWIW, in an unrelated package, sardine-web, I structured it so the JS client's source code was inside the package itself, but setup.py would build the client and remove the source code afterwards, leaving only the source code in the sdist and its compiled result in the wheel. In hindsight, it probably would have been easier had I left the client source code outside of the package and only included it in the sdist via MANIFEST.in. Given hatch's own mechanisms for controlling distributions, plus the convenience of hatch-build-scripts, it might be easier to move src/js/ beside the src/py/reactpy/reactpy/ package and follow the previous suggestion to pyproject.toml, rather than try to find a workaround with the current layout.
