Build Status

DRY data seeding for mongoose.

Simplify mongoose data seeding based on the current running environment of your application. You may use seed-mongoose during test, development and even seed your application with default data during deployment in production environment.

Requirements

Installation

$ npm install --save seed-mongoose

You may opt to install Faker as your test and development seed generator

$ npm install --save-dev faker

Usage

require('seed-mongoose')();

...

mongoose.connect(uristring, mongoOptions, function () {
  require('seed-mongoose')({
    suffix: '_seed',
    logger: winston,
    mongoose: mongoose //This is required
  }, function (error, results) {
    ...
  });
});

How it works

By default seed-mongoose look for environment specific seeds in the seeds directory inside process.cwd() of your application. Example, if you need to seed your application during test you will have to create seeds/test and add model seed files inside it.

seed-mongoose will load any file suffix-ed with Seed as a seed unless custom suffix provided in configurations. Example, if you want to seed your User model during test your need to write your seed as folow:

//in seeds/test/UserSeed.js
var faker = require('faker');

//array of plain object
//to seed in User model
module.exports = [{
    username: faker.internet.userName(),
    email: faker.internet.email()
}];

When connecting event fired by mongoose connection, seed-mongoose will then apply all data seed available for the current application environment .

Seed Types

seed-mongoose accept array type, plain object and functional type seeds.

Object Seed Type

//in seeds/test/UserSeed.js
var faker = require('faker');

//object to seed
//in User model
module.exports = {
    username: faker.internet.userName(),
    email: faker.internet.email()
};

Array Seed Type

//in seeds/test/UserSeed.js
var faker = require('faker');

//array of data to seed
module.exports = [{
    username: faker.internet.userName(),
    email: faker.internet.email()
}];

Functional Seed Type

//in seeds/test/UserSeed.js
var faker = require('faker');

//function to be evaluated to obtain data
module.exports = function(done) {

    var data = [{
        username: faker.internet.userName(),
        email: faker.internet.email()
    }, {
        username: faker.internet.userName(),
        email: faker.internet.email()
    }];

    //remember to tell when your are done
    done(null, data);
};

The same convection must be followed for development and production environment.

Note: Environment specific folder are named after their environment name, e.g if environment is test, then to make sure your test seeds are loaded they must be placed under seeds/test folder for seed-mongoose to pick and apply your seeds. Your may look this repo seeds folder to see example

Configuration

seed-mongoose accept application defined configurations.

Simply, pass the config object into it as below:

var mongoose = require('mongoose');

...

var seed = require('seed-mongoose')({
            cwd: 'data',
            path: 'fixtures',
            logger:console,
            environment: 'development',
            mongoose: mongoose
        });

...
  • cwd current project working directory. Default to process.cwd()
  • path seed path relative to cwd. Default to seeds
  • suffix suffix to use match seeds when loading seeds from a seed directory. Default to Seed
  • logger logger to be used to log progress. Default to console
  • environment seeding environment. Default to process.env.NODE_ENV

Testing

  • Clone this repository

  • Install grunt-cli global

$ npm install -g grunt-cli
  • Install all development dependencies
$ npm install
  • Then run test
$ npm test
