with-package

Run any command with package.json properties exposed as environment variables

Imagine you want to use variables from the package.json in the script commands. Now you can. For example, let us say you want to commit and tag the git branch with the current version label. Install with-package and use it as first keyword in the command

npm install --save-dev with-package

"scripts": {
  "release": "with-package git commit -am pkg.version && with-package git tag pkg.version"
},

Just refer to any primitive property of package.json as pkg.<property name>. Objects and arrays are not supported. If you need to debug the substitution, add --debug or -d flag to the command.

with-package echo this is pkg.description --debug

Note: some of the package.json variables are already exposed as environment variables, see this doc.
