Summary
I made a new npm package called module-analyzr
. It extract the usage of a module in given files or directory or glob-pattern.
https://github.com/taneba/module-analyzr
Example
Imagine if you want to know the usage of React in your project,
# first, install it via npm
npm install -g module-analyzr
# then, in your project
module-analyzr react src
{ importedModules:
[ { moduleName: 'Element', usageAmount: 2 },
{ moduleName: 'Component', usageAmount: 37 } ],
importedDefault: 215,
importedWithNameSpace: 0 }
Output object shows the usage of React in the src directory. It means Element
imported twice, and Component
imported 37ใtimes, and import React from 'react'
215 times!
If it shows importedWithNameSpace
with some number, it means there are number of import * as React from 'react'
.
Motivation
I am a maintainer of a component library made of React in my company. It was hard to grasp how much each component is used in which project. So When I wanted to upgrade my lib with some breaking changes, I had to ask each engineer for the usage of components. module-analyzr
is most useful for this kind of situation. I'm using module-analyzr
in the backend system to analyze each passed github urls and visualize how much each component is used in all of projects!
In closing
It's my first time to ship open source project, so there may be some bugs๐
I've learned much from making this and wanna engage more in the open source community๐
I hope you'll be interested in this library!
