Authentication for Objection.js

This package includes plugins useful for authentication for websites:

• Authenticatable - Generates hashed passwords for a user model. Uses bcrypt under the hood.
• Recoverable - Generates password reset tokens.

Installation

npm install objection-auth

Usage

Authenticatable

// Import the plugin.
const { Authenticatable } = require('objection-auth');
const { Model } = require('objection');

// Mixin the plugin.
const AuthenticatableModel = Authenticatable({
  passwordField: 'password',
  saltRounds: 12,
})(Model);

// Create your model.
class User extends AuthenticatableModel {
  // ...code
}

Verifying a password

In your login controller logic:

const user = await User.query().where('id', 1);

if (!user.verifyPassword) {
  // throw an error
}

Options

passwordField (required)

The field to that the hashed password will be stored on. (required, defaults to 'password')

saltRounds (defaults to slug)

The number of salt rounds as passed to bcrypt.

Recoverable

// Import the plugin.
const { Recoverable } = require('objection-auth');
const { Model } = require('objection');

// Mixin the plugin.
const RecoverableModel = Recoverable({
  tokenField: 'resetPasswordToken',
  tokenExpField: 'resetPasswordExp',
  expiresIn: 60
})(Model);

// Create your model.
class User extends RecoverableModel {
  // ...code
}

Generating a reset token

In your reset password controller logic:

const user = await User.query().where('id', 1);

await user.generateResetToken();
console.log(user.resetPasswordToken);
//

Options

tokenField (defaults to resetPasswordToken)

The field that the reset token is stored on.

tokenExpField (defaults to resetPasswordExp)

The field that the expiration date is stored on.

expiresIn (defaults to 60 minutes)

The expiration time of the token, in minutes.

Chaining Plugins

These plugins can be used together by composing the plugins together:

const { Authenticatable, Recoverable } = require('objection-auth');
const { compose, Model } = require('objection');

const mixins = compose(
  Authenticatable({ saltRounds: 10, passwordField: 'pass' }),
  Recoverable({
    tokenField: 'resetPasswordToken',
    tokenExpField: 'resetPasswordExp',
    expiresIn: 60
  })
);

class User extends mixins(Model) {
  // ...
}
