requirable index.js file to return an array of all .js and .json files within a directory

index.js

'use strict';

var fs = require('fs');

var contents = [];

var files = fs.readdirSync(__dirname);
files.reduce(function (error, key) {
  var file = key.replace(/.json|.js/g, '');
  if (file !== 'index') {
    contents.push(require('./' + key));
  }
});

module.exports = exports = contents;

put all .json files into a data folder and add the index.js from above.

var data = require('../couchdb/data');

var insertData = function (db) {
  var promises = [];

  data.forEach(file => {
    file.forEach(obj => {
      var promise = new Promise((resolve, reject) => {
        db.insert(obj, obj._id, function (error) {
          if (error) {
            reject(error);
          } else {
            resolve(db);
          }
        });
      });

      promises.push(promise);
    });
  });

  return Promise.all(promises).then(() => db);
};
