mongoose-emailable

Mongoose plugin for email address confirmation and express route: automatically sends an email with a "click to confirm address" link to a just-registered user, or to a user that changes its email address.

Clicking the link will flag the email address as "confirmed", thus allowing mails to be sent to this address. No other mails beside the "confirm your address" will be sent to an unconfirmed address.

This module internally uses nodemailer module with Amazon SES transport.

Installation

npm install mongoose-emailable

Usage

Setting up mongoose-emailable is pretty straightfoward:

1. attach plugin to the Mongoose model of your choice (typically, a User-like model)
2. add route to your express application

Configure mongoose model

# User model file...
mongoose = require("mongoose")
emailablePlugin = require("mongoose-emailable").plugin

UserSchema = new mongoose.Schema(
  name:
    type: String
    required: true
)

UserSchema.plugin(emailablePlugin,
  from: "Example.com <no-reply@example.com>" # Any email address you own
  confirmRoute: "https://example.com/account/email/confirm" # Query string will be automatically added
  amazonSES:
    AWSAccessKeyID: "..."
    AWSSecretKey: "..."
)

Configure express app

express = require("express")
emailable = require("mongoose-emailable")
UserModel = require("./path/to/your/mongoose/usermodel")

app = express()

emailable.routes(app,
  model: UserModel # mandatory
  confirm:
    path: "/account/email/confirm"
    template: "emailconfirmation.html"
    messages:
      json: "Cannot confirm email address with JSON GET."
      error500: "An error occured on our side while validating this email address. Please, try refreshing this page or try again later!"
      invalidCombination: "Invalid email/token combination"
      alreadyConfirmed: (user) ->
        return "#{user.email.address} has already been confirmed"
)

And you're set! Users will receive an email asking for confirmation when registering.
