Modules
Authenticable
It lays down the infrastructure for authenticating a user. It extend mongoose model with the following:
email :
An attribute used to store user email address. irina opt to use email address but it can be overriden by supply a custom attribute to use.
password :
An attribute which is used to store user password hash.
encryptPassword(callback(error,authenticable)) :
An instance method which encrypt the current model instance password using bcryptjs.
Example
....
//encypt instance password
user
.encryptPassword(function(error, authenticable) {
if (error) {
console.log(error);
} else {
console.log(authenticable);
}
});
...
comparePassword(password, callback(error,authenticable)) :
An instance method which takes in a plain string password and compare with the instance hashed password to see if they match.
Example
...
//after having model instance
user
.comparePassword(password,function(error, authenticable) {
if (error) {
console.log(error);
} else {
console.log(authenticable);
}
});
...
changePassword(newPassword, callback(error,authenticable)) :
An instance method which takes in a plain string newPassword, hash it and set it as a current password for this authenticable instance.
Example
...
//after having model instance
user
.changePassword(password,function(error, authenticable) {
if (error) {
console.log(error);
} else {
console.log(authenticable);
}
});
...
authenticate(credentials, callback(error,authenticable)) :
A model static method which takes in credentials and additional mongoose query criteria in the format below :
var faker = require('faker');
var credentials = {
email: faker.internet.email(),
password: faker.internet.password(),
...
//additional mongoose criteria
....
};where email is valid email and password is valid password of already registered user. It will then authenticate the given credentials. If they are valid credential a user with the supplied credentials will be returned otherwise corresponding errors will be returned.
Example
var faker = require('faker');
//you may obtain this credentials from anywhere
//this is just a demostration for how credential must be
var credentials = {
email: faker.internet.email(),
password: faker.internet.password()
};
User
.authenticate(credentials,function(error, authenticable) {
if (error) {
console.log(error);
} else {
console.log(authenticable);
}
});
...
Confirmable
Provide a means to confirm user account registration. It extend mongoose model with the following:
confirmationToken :
An attribute which used to store current register user confirmation token.
confirmationTokenExpiryAt :
An attribute that keep tracks of when the confirmation token will expiry. Beyond that, new confirmation token will be generated and notification will be send.
confirmedAt :
An attribute that keep tracks of when user account is confirmed.
confirmationSentAt :
An attribute that keep tracks of when confirmation request is sent.
generateConfirmationToken(callback(error,confirmable)) :
This instance method will generate confirmationToken and confirmationTokenExpiryAt time. It also update and persist an instance before return it.
Example
...
user
.generateConfirmationToken(function(error, confirmable) {
if (error) {
console.log(error);
} else {
console.log(confirmable);
}
});
...
sendConfirmation(callback(error,confirmable)) :
This instance method which utilizes model.send() and send the confirmation notification. On successfully send, it will update confirmationSentAt instance attribute with the current time stamp and persist the instance before return it.
Example
...
user
.sendConfirmation(function(error, confirmable) {
if (error) {
consle.log(error);
} else {
consle.log(confirmable);
}
});
...
confirm(confirmationToken, callback(error,confirmable)) :
This static/class method taken the given confirmationToken and confirm un-confirmed registration which match the given confirmation token. It
will update confirmedAt instance attribute and persist the instance
before return it.
Example
...
User
.confirm('confirmationToken',function(error, confirmable) {
if (error) {
console.log(error);
} else {
console.log(confirmable);
}
});
...
Lockable
Provide a means of locking an account after a specified number of failed sign-in attempts (defaults to 3 attempts). user can unlock account through unlock instructions sent. It extend the model with the following:
failedAttempt :
An attribute which keeps track of failed login attempts.
lockedAt :
An attribute which keeps track of when account is locked.
unlockedAt :
An attribute which keeps track of when and account is unlocked.
unlockToken :
An attribute which store the current unlock token of the locked account.
unlockTokenSentAt :
An attribute which keeps track of when the unlock token notification sent.
unlockTokenExpiryAt :
An attribute which keep track of unlockToken expiration. If unlockToken is expired new token will get generated and set.
generateUnlockToken(callback(error,lockable)) :
An instance method that generate unlockToken and unlockTokenExpiryAt. Instance will get persisted before returned otherwise corresponding errors will get returned.
Example
...
user
.generateUnlockToken(function(error, lockable) {
if (error) {
console.log(error)
} else {
console.log(lockable)
}
});
...
sendLock(callback(error,lockable)) :
An instance method which send account locked notification to the owner. It will set unlockTokenSentAt to track when the lock notification is sent. Instance will get update before returned otherwise corresponding errors will get returned.
Example
...
user
.sendLock(function(error, lockable) {
if (error) {
console.log(error);
} else {
console.log(lockable);
}
});
...
lock(callback(error,lockable)) :
An instance method that used to lock an account. When invoked, it will check if the number of failedAttempts is greater that the configured maximum allowed login attempts, if so the account will get locked by setting lockedAt to the current timestamp of lock invocation. Instance will get persisted before returned otherwise corresponding errors will get returned.
Example
...
user
.lock(function(error, lockable) {
if (error) {
console.log(error);
} else {
console.log(lockable);
}
});
...
unlock(unlockToken, callback(error,lockable)) :
A model static method which unlock a locked account with the provided unlockToken. If the token expired the new unlockToken will get generated. If token is valid, locked account will get unlocked and unlockedAt attribute will be set to current timestamp and failedAttempts will get set to 0. Instance unlocked will get persisted before returned otherwise corrensponding errors will get returned.
Example
...
User
.unlock(unlockToken, function(error, lockable) {
if (error) {
console.log(error);
} else {
console.log(lockable);
}
});
...
Recoverable
Lays out infrastructure of resets the user password and sends reset instructions. It extend model with the following:
recoveryToken :
An attribute that store recovery token
recoveryTokenExpiryAt :
An attribute that track when the recoverable token is expiring.
recoverySentAt :
An attribute that keep track as of when the recovery notification is sent.
recoveredAt :
An attribute which keeps track of when the password was recovered.
generateRecoveryToken(callback(error,recoverable)) :
An instance method which used to generate recoveryToken and set recoveryTokenExpiryAt timestamp. Instance will get persisted before returned othewise corresponding errors will get returned.
Example
...
user
.generateRecoveryToken(function(error, recoverable) {
if (error) {
console.log(error)
} else {
console.log(recoverable);
}
});
...
sendRecovery(callback(error,recoverable)) :
An instance method which is used to send recovery notification to the user. It will set recoveryTokenSentAt timestamp. Instance will get persisted before returned othewise corresponding errors will get returned.
Example
...
user
.sendRecovery(function(error, recoverable) {
if (error) {
console.log(error);
} else {
console.log(recoverable);
}
});
...
requestRecover(criteria, callback(error,recoverable)) :
A model static method which is used to request account password recovery. It utilize generateRecoveryToken and sendRecovery to generate recovery token and send it.
Example
...
User
.requestRecover({email:'[email protected]'},function(error, recoverable) {
if (error) {
console.log(error);
} else {
console.log(recoverable);
}
});
...
recover(recoveryToken, newPassword, callback(error,recoverable)) :
A model static method which is used to recover an account with the matched recoverToken. The newPassword provided will get encrypted before set as user password. It will set recoveredAt before persist the model.
Example
...
User
.recover(
recoveryToken,
faker.internet.password(),
function(error, recoverable) {
if (error) {
console.log(error);
} else {
console.log(recoverable);
}
});
...
Registerable
Handles signing up users through a registration process, also allowing them to edit and destroy their account. It extend model with the following:
registeredAt :
An attribute which keeps track of whn an account is registered.
unregisteredAt :
An attribute which keep tracks of when an account is unregistered.
register(credentials, callback(error,registerable)) :
A model static method which is used to register provided credentials. It takes care of checking if email is taken and validating credentials. It will return registered user otherwise corresponding registration errors.
Example
var faker = require('faker');
var credentials = {
email: faker.internet.email(),
password: faker.internet.password()
}
User
.register(credentials, function(error, registerable) {
if (error) {
console.log(error);
} else {
console.log(registerable);
}
});
...
unregister(callback(error,registerable)) :
An instance method which allow to unregister(destroy a user). The currently implementation is to set unregiesteredAt to current timestamp of the invocation. Instance will get persisted before returned otherwise corresponding errors will be returned.
Example:
...
user
.unregister(function(error, registerable) {
if (error) {
console.log(error);
} else {
console.log(registerable);
}
});
...
Trackable
Provide a means of tracking user signin activities. It extend provided model with the followings:
signInCount :
Keeps track of number of count a user have been sign in into you API
currentSignInAt :
Keeps track of the latest time when user signed in into you API
currentSignInIpAddress :
Keeps track of the latest IP address a user used to log with into your API
lastSignInAt :
Keeps track of the previous sign in time prior to the current sign in.
lastSignInIpAddress :
Keeps track of the previous IP address user used to log with into your API
track(ipAddress,callback(error,trackable)) :
This is model instance method, which when called with the IP address, it will update current tracking details and set the provided IP address as the currentSignInIpAddress. On successfully tracking, a provided callback will be get invoked and provided with error if occur and the current updated model instance.
Example
...
User
.findOne({email:'validEmail'})
.exec(function(error,user){
if(error){
console.log(error);
}
else{
user
.track('validIpAddress',function(error,trackable){
if(error){
console.log(error);
}
else{
console.log(trackable);
}
});
}
});
...
Sending Notifications
The default implementation of irina to send notifications is noop. This is because there are different use case(s) when it come on sending notifications.
Due to that reason, irina requires your model to implement send method which accept type, authentication, done as it argurments.
type :
Refer to the type of notifcation to be sent. There are just three types which are Account confirmation, Account recovery and Password recover which are sent when new account is registered, an account is locked and need to be unlocked and when account is requesting to recover the password repsectively.
authenticable :
Refer to the current user model instance.
done :
Is the callback that you must call after finish sending the notification. By default this callback will update notification send details based on the usage.
How to implement a send
Simple add send into your model as instance methods.
var UserSchema = new Schema({
...
});
//the add send
UserSchema.methods.send = function(type, authenticable, done) {
//if we send confirmation email
if (type === 'Account confirmation') {
//your notification sending implementation
//i.e email, sms, etc
console
.log(
'Notification type: %s.\nAuthenticable: %s \n',
type,
JSON.stringify(authenticable)
);
done();
}
//if we send account recovery
if (type === 'Password recovery') {
//your notification sending implementation
//i.e email, sms, etc
console
.log(
'Notification type: %s.\nAuthenticable: %s \n',
type,
JSON.stringify(authenticable)
);
done();
}
//if we send account locked information
if (type === 'Account recovery') {
//your notification sending implementation
//i.e email, sms, etc
console
.log(
'Notification type: %s.\nAuthenticable: %s \n',
type,
JSON.stringify(authenticable)
);
done();
}
...
};
...
Thats all needed and irina will be able to utilize your send implementation.
Sending Issues
It is recommended to use job queue like kue when implementing your send to reduce your API response time.
Testing
Clone this repository
Install all development dependencies
$ npm install- Then run test
$ npm testContribute
It will be nice, if you open an issue first so that we can know what is going on, then, fork this repo and push in your ideas. Do not forget to add a bit of test(s) of what value you adding.
