This script synchronizes versions of dependencies from a source package. For each dependency that exists in both the source and target, the version from the source is adopted. The source package does not need to be installed; it is looked up from npm or git as required.
To install:
npm install -g sync-dependencies
Sync dependencies from the version of a package that is specified in package.json:
sync-dependencies --source terriajs
Sync dependencies from a package.json on disk:
sync-dependencies --source terriajs --from ./packages/terriajs/package.json
