A regular Expression to parse ECMAScript6 import syntax

regex-es6-imports.js

let regex = `import
  (?:
    ["'\s]*
      ([\w*{}\n, ]+)
      from\s*
  )?
  ["'\s]*
    ([@\w/_-]+)
  ["'\s]*
;?
`;

// Matches...
/*
import {
  Component
} from '@angular2/core';

import defaultMember from "module-name";
import   *    as name from "module-name  ";
import   {  member }   from "  module-name";
import { member as alias } from "module-name";
import { member1 , member2 } from "module-name";
import { member1 , member2 as alias2 , member3 as alias3 } from "module-name";
import defaultMember, { member, member } from "module-name";
import defaultMember, * as name from "module-name";
import "module-name";
*/

thanks @ganeshkbhat, I used it for the reference. Mine particular case to find occurences of specific import package.

import(?:[\s.*]([\w*{}\n\r\t, ]+)[\s*]from)\s+['"]lodash['"];
                                                  ^^^^^^
