depstats v0.2.0

depstats

Groups modules by package and includes stats.

Example

Given an app with express dependency at expressAppDir.

const { depStats } = require('depstats')
const { inspect } = require('util')

const res = await depStats(expressAppDir, [
  './node_modules/express/lib/middleware/query.js',
  './node_modules/express/lib/middleware/init.js',
  './node_modules/express/lib/router/layer.js',
  './node_modules/express/lib/router/index.js',
  './node_modules/express/lib/express.js',
  './node_modules/express/index.js',
  './node_modules/express/application.js',
  './node_modules/body-parser/lib/types/json.js',
  './node_modules/body-parser/lib/read.js',
  './node_modules/body-parser/index.js',
])
console.log(inspect(Array.from(res), { depth: 5 }))

Outputs the below where full: is the actual full path for your case.

ModuleInfo

Allows retrieving info including of its containing package for a specific file.

Given depstats obtained previously.

const file = path.resolve(
  appRootDir,
  './node_modules/body-parser/lib/types/text.js'
)
const packageInfo = modulePackageInfo(depstats, file)
console.log(inspect(packageInfo, { depth: 5 }))

Outputs the below where full: is the actual full path for your case.

{
  pkg: {
    name: 'body-parser',
    version: '1.19.0',
    main: 'index.js',
    fullPath: 'full:node_modules/body-parser',
    relPath: 'node_modules/body-parser'
  },
  mdl: {
    modulePath: 'lib/types/text.js',
    relPath: 'node_modules/body-parser/lib/types/text.js',
    fullPath: 'full:node_modules/body-parser/lib/types/text.js',
    size: 2285,
