How to write a Mongoose model in ES6 / ES2015

Question

I want to write my mongoose model in ES6. Basically replace module.exports and other ES5 things wherever possible. Here is what I have.

import mongo         


        

Answer 1

For those who find this searching around, the original question seems pretty valid to me. I'm using Babel transpiling ES6+ down to 5. My custom mongoose methods did not play well with my async/await code in my calling class. Notably this was null in my instance methods. Using the solution provided here, I was able to arrive at this solution that hopefully helps others searching around.

import mongoose from 'mongoose'

class Tenant extends mongoose.Schema {
  constructor() {
    const tenant = super({
      pg_id: Number,
      name: String,
      ...
    })

    tenant.methods.getAccountFields = this.getAccountFields
    tenant.methods.getCustomerTypes = this.getCustomerTypes
    tenant.methods.getContactFields = this.getContactFields
    ...
    tenant.methods.getModelFields = this.getModelFields

    return tenant
  }

  getAccountFields() {
    return this.getModelFields(this.account_fields_mapping)
  }

  getCustomerTypes() {
    //code
  }

  getContactFields() {
    //code
  }

  ...

  getModelFields(fields_mapping) {
    //code
  }
}

export default mongoose.model('Tenant', new Tenant)
