Manage multiple email addresses per user (or other model/doc) with this mongoose schema plugin.
Something like...
{
email_addresses: [
{
email_address: {type: String, unique: unique},
primary: Date,
verification: {
date: Date,
code: String,
code_expiration: Date
}
}
]
}
Install it...
npm install mongoose-email-address-manager
Plug it in... (defaults are shown)
var db = require('mongoose'),
emailAddressManagerPlugin = require('mongoose-email-address-manager'),
UserSchema = db.Schema(),
options = {
_id: true, // removes _id fields from email_address sub docs when set to false
index: true, // sets indexes on emails and verification code
unique: true, // throws a mongo error if emails are not unique
sparse: true, // sparse or not
required: false, // verifies that at least one email sub doc exists
verificationCodePrefix: 'emvc-', // useful for web pages that deal with more than one type of access code / validation code (like mobile numbers)
verificationCodeExpiration: 0, // the amount of hours to add to the expiration date of validation code, defaults to never expire (0)
emailValidationRegex: /^.+@.+$/, // very simple regex validator for email addresses, overwrite if you want something more powerful :)
style: function (key) { // keeping you inline with your style guide, if you require camelCase or Snake_Case or so be it... override your keys with this function, default being under_score
return key
}
};
UserSchema.plugin(emailAddressManagerPlugin, options);
Make the model...
var User = db.model('user', UserSchema);
Make the instance or find the instance with the statics below ...
var user = new User({
email_addresses: [{
email_address: '[email protected]'
}]
});
Use the statics...
User.findOneByEmail - like mongooses findOne except the first arg is an email_address instead of a condition
User.findByEmail - same here... this is useful if unique is set to false and more than one doc has the same email
User.findByEmailVerificationCode - find the doc by one of it's email verification codes
User.emailExists - use this to check if email exists within entire collection so you can quickly throw that "email already exists" error on your signup forms or something with that cool new API
Empower your self with easy methods on the instance...
user.addEmail // add a new email
user.addEmailAndSave
user.getEmail // find the email object within the doc
user.getPrimaryEmail // returns the email object
user.setPrimaryEmail // changes or sets the primary email address (will not save)
user.setPrimaryEmailAndSave // sets the primary email and saves the doc
user.isPrimaryEmail // is it?
user.removeEmail // removes an email address (will not save)
user.removeEmailAndSave
user.emailExists // do we have the email in the doc? It's always a yes or no answer
user.startEmailVerificationProcess // this configures and saves some stuff like a verification code and expiration date for the email (will not save)
user.startEmailVerificationProcessAndSave
user.getEmailByVerificationCode // if you don't have the doc in memory find it first with the static: findByEmailVerificationCode
user.setVerifiedEmail // set an email as verified (will not save)
user.setVerifiedEmailAndSave
user.isVerifiedEmail // returns boolean on rather or not that email address has been verified
Use the one and only extremely powerful virtual field that hands down that primary email address at all times unless it's undefined
user.email; // the primary email or equivalent of user.getPrimaryEmail().email_address
Misc Notes
On creation/save the first email will become primary pre save if there is not a current primary email address unless there are no email addresses. On removal of an email address a new primary will be elected Methods that interact with the DB are Async/Await/Promise compatible (callbacks not currently supported)
Please refer to the tests for further use.
