folder-loader

Load node modules from folder, acts as they are one module.

Example

Place index.js like this in the folder you want to export as a module:

const loader = require('folder-loader');

module.exports = loader(__dirname, __filename);

the code above will exports every file/folder in this dir as an object with filename as key.

if you are exports sequelize module use iterator:

const loader = require('folder-loader'),
    Sequelize = require('sequelize'),
    debug = require('debug')('models::index'),
    config = require('config'); // Add your real config file here.
    
let sequelize = Sequelize(config),
    db = {};

for (let model_func of loader.iterator(__dirname, __filename)) {
  try {
    let model = model_func(sequelize, Sequelize);
    db[model.name] = model;
    debug("Import model " + model.name + " success.");
  }
  catch (error) {
    debug("Import model error: " + error);
  }
}

for (let modelName in db) {
  if (db[modelName].associate) {
    db[modelName].associate(db);
  }
}

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;
