This is a demo of adding features to browserify to allow it to recognize its own bundles and consume them more easily. See substack/node-browserify#1151.
To run the demo:
git clonethis repocdinto repo dirnpm installsh setup.sh- Then
git checkout stock node ./bundler git checkout pragma node ./bundler
On the stock branch the bundler script will be run with stock browserify / dependencies. It should produce a dist/b.js bundle that includes the extraneous file src/b/dependency.js and error out when attempting to create dist/c.js.
On the pragma branch it will run a modified version of browserify / dependencies that adds and detects pragmas in bundles. dist/b.js should now be created without the extraneous file and dist/c.js should be successfully created.
