match-requires

Match require statements in a string. Returns an array of matching require statements. Each match is an object with line number, variable name, and module name. Statements in code comments are ignored.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.

Install

Install with npm:

$ npm install --save match-requires

Usage

const matches = require('match-requires');
console.log(matches('require(\'a-b-c\');\nvar fooBar = require(\'foo-bar\');'));

Returns:

[ { string: 'require(\'a-b-c\');', 
    variable: '', 
    name: 'a-b-c' },
  { string: 'var fooBar = require(\'foo-bar\');',
    variable: 'fooBar',
    name: 'foo-bar' } ]

Ignore requires in code comments

To ignore require() statements found inside code comments, pass true as the second argument to strip comments before matching. Alternatively, you may pass a function as the second argument to use your own approach to stripping comments.

Without comments stripped

console.log(matches('/* require(\'a-b-c\');*/\nvar fooBar = require(\'foo-bar\');')); 
// [ { string: 'require(\'a-b-c\');', variable: '', name: 'a-b-c' },
//   { string: 'var fooBar = require(\'foo-bar\');',
//     variable: 'fooBar',
//     name: 'foo-bar' } ]

With comments stripped

console.log(matches('/* require(\'a-b-c\');*/\nvar fooBar = require(\'foo-bar\');', true));
// [ { string: 'var fooBar = require(\'foo-bar\');',
//     variable: 'fooBar',
//     name: 'foo-bar' } ]

With custom function

const str = '/* require(\'a-b-c\');*/\nvar fooBar = require(\'foo-bar\');';
const fn = require('some-comment-stripping-library');
console.log(matches(str, fn));
// [ { string: 'var fooBar = require(\'foo-bar\');',
//     variable: 'fooBar',
//     name: 'foo-bar' } ]
