DRY data seeding for sails.

Simplify seeding data to your persistent storage of your choice based on the current running environment obtained from sails.config.environment of your application. You may use sails-hook-seed during test, development and even seed your application with default data during deployment in production environment.

Note: This requires Sails v0.11.0+. If v0.11.0+ isn't published to NPM yet, you'll need to install it via Github.

Installation

$ npm install --save sails-hook-seed

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

$ npm install --save-dev faker

Usage

By default sails-hook-seed look for environment specific seeds in the seeds directory inside sails.appPath 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.

sails-hook-seed will load any file suffix-ed with Seed as a seed. Example, if you want to seed your User model during test your need to write your seed as folow:

//in seed/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()
}];

Seed Types

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

Object Seed Type

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

Configuration

sails-hook-seed accept application defined configuration by utilizing sails configuration api. In sails config directory add config/seed.js and you will be able to override all the defauts configurations.

Simply, copy the below and add it to your config/seed.js

module.exports.seed = {
    //directory where migration resides
    //relative to `sails.appPath`
    path: 'seeds',
 
    //enable or disable seeding
    active: true
}

Fork this repo and push in your ideas. Do not forget to add a bit of test(s) of what value you adding.

TODO

  • Allow specifying custom find attributes(criteria) in seeds
  • Remove associations and collection data type from seed finder
  • Adding seed dependencies management to allow one seed to depend on other seed(s)
  • Use rails migrations dependencies style to allow seeding for associations(inspiration)
  • Adding beforeSeed hook(s)
  • Adding afterSeed hook(s)
  • Add ability to specify seed run type(EVERY,ONCE)
  • Add seed phases (cleanup, prepare, seed, done)
  • Make seed event emmitter to allow them to interact and trigger other seeds
  • Add ability to clean up all seeded data
  • Controll depth of loading associations
