Utils to work with package.json files.

Install globally or locally

npm install -g package-utils

package-merge

With package-merge you merge multiple files into one package.json file.

package-merge package.a.json package.b.json package.c.json > package.json

On the command line it exits when there is no strategy to merge the values. In the API you can provide custom handling via callback.

package-deps

package-deps -d a/package.json b/package.json
mkdirp@0.5.1
moment@2.11.2

With package-deps you get the dependencies of all the project files passed in. With the -d option this also includes the devDependencies. On the command line clashing versions will be reported and the last version wins.

package-resolve

Resolves dependencies set to RESOLVE to what's in the dict.

cat package.json | package-resolve dict.json > out.json
