Scans your code to find all the require() to tell you what you actually need for the node project. Uses a single file as the starting point then does depth first search. Optional -- It can also update your package.json after to only include the needed modules under dependencies.

Usage

install

$ npm i what-i-actually-need -g

run

Run the following in a node project. By default it uses index.js as the entry point to start the scan.

$ what-i-actually-need

example output:

-- Running What-I-Actually-Need ---

index.js
--> node-sass
--> css-modules-require-hook
--> babel-register

server.js
--> nconf
--> log4js
--> http
--> https
--> fs
--> path

--------------------
