Grunt mustache re-implementation

grunt.js

// At this time, grunt-mustache was giving me shit so I rewrote it for what I needed...

module.exports = function (grunt) {
  // Project configuration.
  grunt.initConfig({
    mustache: {
      template: {
        src: 'template.svg.mustache',
        dest: 'template.svg',
        partials: 'partials/*.mustache'
      }
    },
    watch: {
      mustache: {
        files: '<config:mustache.template.src>',
        tasks: 'mustache'
      }
    }
  });

  // Load local tasks.
  var mustache = require('mustache'),
      fs = require('fs'),
      path = require('path');
  grunt.registerMultiTask('mustache', 'Render mustache files', function () {
    var data = this.data,
        srcFile = data.src,
        srcContent = grunt.file.read(srcFile),
        partials = data.partials || [],
        partialArr = grunt.file.expandFiles(partials),
        partialMap = {};

    partialArr.forEach(function (partial) {
      var partialItem = grunt.file.read(partial),
          filename = path.basename(partial, '.mustache');
      partialMap[filename] = partialItem;
    });

    var retVal = mustache.render(srcContent, {}, partialMap),
        destFile = data.dest;
    grunt.file.write(destFile, retVal);
  });

  // Default task.
  grunt.registerTask('default', 'mustache');
