i like to minify all js-files from a config.php by gulp.

//config.php
c::set('myvar', true);

c::set('styles', [
  'test1.css',
  'test2.css'
]);

c::set('scripts', array(
  'node_modules/abc.min.js',
  'node_modules/def.js',
  'assets/js/xyz.js' 
));

i read the file by fs.readFile to a string. so far so good.
unfortunately i can't find the correct regex/match to get only the paths between:

c::set('scripts', array(

and

));

anybody knows the right regex?
i am regex newbie. tnx

Update

With the regex from @Ken following the working solution:

var gulp = require('gulp'),
    fs = require("fs"),
    concat = require('gulp-concat'),
    uglify = require('gulp-uglify');

var jsfromconfigphp = [];

gulp.task('get-js-by-config-php', function(done) {
  const regex = /\s+(\'[\w\/\.]+\.js\')/gi;
  let m;
  fs.readFile('site/config/config.php', {encoding: 'utf-8', flag: 'rs'}, function(e, data) {
    if (e) {
      return console.log(e);
    }
    while ((m = regex.exec(data)) !== null) {
      // This is necessary to avoid infinite loops with zero-width matches
      if (m.index === regex.lastIndex) {
        regex.lastIndex++;
      }
      // The result can be accessed through the `m`-variable.
      m.forEach((match, index) => {
        if(index === 1) {
          console.log(`Found match, group ${index}: ${match}`);
          jsfromconfigphp.push(match.slice(1, -1));
        }
      });
    }
    done();
  });
});

// wait for get-js-by-config-php is done
gulp.task('build-js', ['get-js-by-config-php'], function() {
  return gulp.src(jsfromconfigphp)
  .pipe(concat('main.min.js'))
  .pipe(uglify({
    compress: {
      drop_console: true
    }
  }))
  .pipe(gulp.dest('assets/js'));
});
