Moleculer Service Factory

npm i moleculer-sf

Idea

This module uses ServiceFactory to hook, then returns a mixin that will be injected into the service's schema before service is created

So instead of having to write (or copy) multiple lines of code, you just need to write it once and push into this module, great.

• For all services

// service-factory.js
const moleculer = require('moleculer')
const moleculerServiceFactory = require('moleculer-sf')

// global all factory plugins
const plugins = [
  'catch-removed-event', // or with prefix moleculer-sf-catch-removed-event
  'prevent-change-created-at', // or require('moleculer-sf-prevent-change-created-at')
  'mixin-db', // or just string without prefix
]

module.exports = moleculerServiceFactory(moleculer, plugins)

P/S: do not forget to install factory dependencies

npm i moleculer-sf-mixin-db

// global appy to services
// moleculer.config.js
module.exports = {
  ServiceFactory: require('./service-factory.js'),
  // ...
}

// - For excepted services
// some.service.js
module.exports = {
  name: 'some-service',
  schema: require('some-service-schema'),
  // $factory will be removed from schema before service created
  $factory: {
    global: false, // ignore global all-factory-plugins
    plugins: [
      'mixin-db', // add mixin-db only
    ]
  },
}

Plugin module

Plugin module can be

• Function(serviceSchema, moleculer) => ServiceSchema or array of ServiceSchema

Service factory module will add all return except null from plugin

Structure

module.exports = function(schema, moleculer) {
  // ...
  return {
    // $pluginOrder: Number.MAX_SAFE_INTEGER, // special: biggest will be placed at end of mixins array
    // actions
    // methods
    // settings
  }
}
