require-call

A more simple way to find all require() calls.

Installation

npm install require-call

Usage

API

parseDependencies(code: String, replace: Function = null)

Example

Source code:

require('foo')
// require('bar')

const fs = require('fs')
const resolve = require('require-call')
 
fs.readFile(file, 'utf8', (err, content) => {
  console.log(resolve(content, (item) => {
    return item.string
  }))
})

Output:

{
  code: 'require(\'foo\')\n// require(\'bar\')\n',
  resource: [
    {
      string: 'require(\'foo\')',
      path: 'foo',
      start: 0,
      end: 14
    }
  ]
}
