Python Tree Shaking
English README is under construction.
Install
pip install tree-shaking
Be noted tree-shaking requires Python >= 3.12.
Usage
Project tree (before):
# my example project
/workspace/hello-world
|= .venv
|= hello_world
|- __init__.py
|- __main__.py
|- ...
|= dist
|- pyprojet.toml
|- tree_shaking.yaml
|- ...
"tree_shaking.yaml" content:
root: .
search_paths:
- <root>/.venv/Lib/site-packages
- <root>
entries:
- <root>/hello_world/__main__.py
Create a temporary script (e.g. "build.py"), code like this:
import tree_shaking
tree_shaking.build_graph_modules("./tree_shaking.yaml")
tree_shaking.dump_tree("./tree_shaking.yaml", "./dist/minified_libs")
After running, the project tree changes:
# my example project
/workspace/hello-world
|= .venv
|= hello_world
|- __init__.py
|- __main__.py
|- ...
|= dist
|= minified_libs # updated
|= ...
|- pyprojet.toml
|- tree_shaking.yaml
|- ...
You can temporarily exclude ".venv/Lib/site-packages", and add "dist/minified_libs" to Python's sys.path (put it at the first place) to test if worked.
After testing, compress "dist/minified_libs" to zip, and compare its size with ".venv/Lib/site-packages" -- the more heavy dependencies you have, the more notable changes on size reduction.
Incremental Updates
Just rerun "build.py", outputs results to the same path as last time, tree-shaking will find the changed parts and do only necessary adding/deleting operations to the target directory.
