npm-deps(1)

npm-deps(1) is a nifty little script that scans subdirectories searching for
nested package.json files, and merges all the dependencies together in a
single package.json file that is outputted to stdout.

A base template passed through standard input is used to produce the root
package.json file. This allows package.json to be ignored by version
control systems, which conflict with auto-generated files. Base package
attributes, like name and version, can be stored in a separate file such as
package-base.json, and kept in version control.

Example

$ cd my_cool_project
$ npm-deps < package-base.json > package.json

Installation

$ npm install -g npm-deps

Command line options

-h, --help output usage information
-V, --version output the version number
-s, --silent do not print out warnings
-o, --output [file] output to a file

Conflicts

npm-deps(1) will warn you about any potential conflicts of the versions
declared in the multiple package.json files
