Utils

compare

compares before and after versions of a package.json file to report stats

• total dependencies before
• total dependencies after
• number of dependencies changed (version)
• number of dependencies removed
• number of dependencies added

Usage:

npm-utils compare <before> <after> [--csv] [--output-file]

compares before and after versions of a package.json file and reports stats

Positionals:
  before  path to package.json before changes                [string] [required]
  after   path to package.json before changes                [string] [required]

Options:
      --help         Show help                                         [boolean]
      --version      Show version number                               [boolean]
  -c, --csv          output results in csv format                      [boolean]
  -o, --output-file  provide a path to output file                     [boolean]

Development

npm-utils is built with Typescript and yargs

Developing locally

git clone git@github.com:gpspake/npm-utils.git
cd npm-utils
yarn
yarn link
which npm-utils

Adding new commands

To add a new command, create a yargs command module to the commands directory and add it to the commands array in commands/index.ts. Place any reusable code in the lib directory.

Add new ts files to files in tsconfig.json
