trying to get twig data to work

twig.js

'use strict';

var path = require('path');
var gulp = require('gulp');
var conf = require('./conf');

var twig = require('gulp-twig');
var data = require('gulp-data');

var getJsonData = function(file) {
    var foo = path.join(conf.paths.builds, '/data/', path.basename(file.path.replace('twig.html', 'json')));
    console.log(foo);
    return require(foo);
};

gulp.task('twig-templates', function () {
    return gulp.src([
            path.join(conf.paths.builds, '/*.twig.html')
        ])
        .pipe(data(getJsonData))
        .pipe(twig())
        .pipe(gulp.dest(conf.paths.src));
});
