Installing `webpack-q` `webpack-q-cli` executables

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install webpack-q-cli

It will make webpack-q webpack-q-cli commands available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall webpack-q-cli uninstalls.

Fully traverse a graph

Full graph traversal in html

# Output a graphviz dot file 
webpack-q stats.json traverse-entrypoint entry-1 -fdot

#output json
webpack-q stats.json traverse-entrypoint entry-1 -fjson

#output html viz with d3
webpack-q stats.json traverse-entrypoint entry-1 -fhtml

Find the ways that an entrypoint arrives at a chunk

Useful for finding out why your commons chunk has been imported on initial page load. HTML viz shows forces between chunks and makes it easy to spot offenders

webpack-q stats.json paths-to-chunk my-entrypoint 5332

In this example, the node in the middle clearly joins multiple chunks together. Splitting it up may improve load performance.

Roadmap

More webpack stats compatibility

Repo already contains sample stats.json files that can be encoded
