Seeder support (feature request)

[MartinBucko]

Idea

It will be cool to have build in template generator for service data seeder build in. :) https://github.com/thosakwe/feathers-seeder

Steps to reproduce

New services generated seed feature.

Expected behavior

First install dependencies:

npm i feathers-seeder

It should configure app with seed config in app.js:

const seeder = require('./seeder')
 app.configure(seeder)

It should have (in root probably) seeder.js script:

const seeder = require('feathers-seeder')
const usersSeed = require('./services/users/users.seed')

function seederOptions(app) {
  let options = {
    // delete globally all before seed
    // delete: false,

    // disable globally
    disable: false,

    // here add services to seed
    services: [usersSeed(app)]
  }

  return seeder(options)
}

module.exports = seederOptions

It should generate script service/users.seed.js (example only):

module.exports = function userSeed(app) {
  return {
    count: 1,
    delete: true,
    path: 'users',
    template: {
      name: '{{name.firstName}}',
      surname: '{{name.lastName}}',
      email: '{{internet.email}}',
      language: 'en',
      roles: ['basic'],
      loginFrom: 'web',
      loggedInAt: new Date(),
      isTest: true
    }
  }
}

Actual behavior

(No seeder support.) But we have already great tools in our hands. Sure my examples are quick and dirty. It should be optimised.

Thank You :)

Seeding a realistic set of tables would require seeding foreign keys. This is the main impediment to including a seeder.

I am not aware of a seeder repo which has that capability. Do you have an alternative or thoughts on this?

[MartinBucko]

@eddyystop Its possible to use callback in seeder options. There are called after record was created. This is way how to deal with foreign keys. Check the callback example in configuration docs: https://github.com/thosakwe/feathers-seeder#configuration

[MartinBucko]

Actually use of callbacks is little bit tricky and there is also problem of unpredictable execution order of more seeders. executing order of service array #9

Thanks for this info. I am looking in an alternative direction.
