packcomp

Compare the dependencies and devDependencies keys (sections) from two or more package.json files.

Install

npm install packcomp -g

Usage

packcomp <package.json #1> <package.json #2> [<package.json #3>...]

If the version number is not identical or missing in one of the packages then it will be reported. If it is identical in all packages then it will be ignored and skipped (i.e. no output).

The package.json files can be relative paths to local files or URLs that will return a package.json object or a mixture of both.

Examples

packcomp . ../other-repo1 ../other-repo2
packcomp ../path/to/package/file/ https://<somedomain.com>/<some-path>/package.json
