• Swagger

• swagger project create <name>

• in app.js:

var SwaggerUi = require('swagger-tools/middleware/swagger-ui');

in create():
app.use(SwaggerUi(swaggerExpress.runner.swagger));

• create settings.js in config:

module.exports = {

  db: 'mongodb://mongo/vote',

  port: '9100',

};

• create directory "models"
• create index.js

var mongoose = require('mongoose');

var settings = require('../config/settings');

mongoose.connect(settings.db, function (err) {

  if (err) {

    console.error('connect to %s error: ', settings.db, err.message);

    process.exit(1);

  }

});

// models

require('./vote');

var Vote = mongoose.model('Vote');

module.exports = {Vote};

• create vote.js

var mongoose = require('mongoose');

var Schema = mongoose.Schema;

var VoteSchema = new Schema({

  Result: Number

});

module.exports = mongoose.model('Vote', VoteSchema);
