Learn Jwt, Mongodb and Nightmare

This playlist will be a smorgasbord of Auth0 authentication and authorization topics. Everything from adding Auth0 to various apps, customizing your Auth0 settings, adding specific rules / audiences / features, and debugging errors. 

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

Auth0 Tips and Tricks 

MongoDB has a quite powerful aggregation framework that allows you to write data processing pipelines. Documents in the MongoDB collection go through a series of stages or a pipeline that transforms them into an aggregated result. In this short video series, you will learn how to write aggregations in MongoDB.

MongoDB Aggregation Framework

JSON Web Token (JWT) is a low overhead option for authentication that is easy to implement and scales with your application. There is no need to store session data as everything you need is stored in an encoded string sent in the JWT, significantly reducing database overhead for your servers.

In this course, we will build a simple authentication server that will act as a token issuer, and we will use those tokens to access resources on an API.  Starting from scratch, you will learn how easy token based authentication can be and will understand how to use them on your APIs as well as on the front end of your web applications.

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

JSON Web Token (JWT) Authentication with Node.js and Auth0

JSON Web Tokens (JWT) are a more modern approach to authentication. As the web moves to a greater separation between the client and server, JWT provides a terrific alternative to traditional cookie based authentication models. For more information on JWT visit http://jwt.io/

In this series, we’ll be building a simple application to get random user information from a node server with an Angular client. We’ll then implement JWT to protect the random user resource on the server and then work through the frontend to get JWT authentication working.

By the end, we’ll have an application which has a single username/password combination (for simplicity) and uses tokens to authorize the client to see the random user information. You’ll be able to login, get random users, and logout.

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

AngularJS Authentication with JWT

Adding middleware to the node server to decode and verify the token sent from the client. And tidying up the rest of the application. Finally, a walkthrough of the whole process.

Finalizing JWT Authentication with AngularJS

Creating the basic node server to serve up random users via API endpoints.

Basic Server Setup for JWT Authentication

Adding JWT support to the client. Storing the token in local storage, then creating a http interceptor to add the token to requests made to the server. Also implementing logout.


Auth Interceptor in Angular for JWT

A basic introduction to the mechanics of JWTs and the application we will be building in this lesson series.

JSON Web Token (JWT) Introduction

Adding JWT support to the server. Signing a JSON object as a payload and sending the signed token to the browser on authentication.

Server JWT Authentication Setup

Mongoose allows you to easily select resources by ID from your MongoDB. This is an important aspect to creating an API.

Select by ID with Mongoose and Express

JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.

In this lesson we will look at all of the pieces that combine together to create a JWT (j AWT) or JSON Web Token. You will use node to create a JWT, and then verify it in the JWT debugger.

Creating JWTs (JSON Web Tokens) in Node

Setting up a login on the angular app and an authentication endpoint on the server.

JWT Authentication Setup

Learn how to import data into your MongoDB and then use Express to serve a simple Node.js API.

First API with Node.js, Express and MongoDB

Creating a basic Angular application to access the random users resource. Also setting up CORS on the node server to enable the resource sharing across different domains (ports in our case).

Client Setup for JWT Authentication

Nightmare is a high-level browser automation library.

The goal is to expose just a few simple methods, and have an API that feels synchronous for each block of scripting, rather than deeply nested callbacks. It's designed for automating tasks across sites that don't have APIs.

Many pages you'll want to grab data from will require you to log in first. This video demonstrates how to log in and grab whatever data off the page you will need.

Scraping Data from Sites with Login Forms with Nightmare

Many websites have more than just simple static content. Dynamic content which is rendered by JavaScript requires browser to be able to scrape data. This video demonstrates how to use Nightmare (which is a wrapper around Electron) to launch a url and scrape dynamic data.

Scraping Dynamic JavaScript Websites with Nightmare

This lesson will digitally sign the IBM Domino user information into a JWT which can then be sent from the server to the client.

This JWT can then be sent back from the client to the server and the role information within the JWT file can be decrypted to determine a users level of functional access.

Encrypt IBM Domino User Roles Data into a JWT in a Express Application

This lesson will take the JWT sent from Express and store it in the browser local storage.  It will then resend the JWT back to the Express server when a HTTP call is made for additional IBM Domino Data.

This stateless method allows the server to trust what user roles the logged in user has to restrict what Express routes the user can call.  For instance you might want to restrict all Admin routes to only users which have the Admin role in the Domino ACL.

Send JWT Encrypted User Role Data from Client Local Storage to Express Server

This lesson will extract the JWT from the authorisation HTTP header and then decode it with the secret.

It will then check to make sure it contains a specific user role value to determine if a specific route can be called in Express.

Decode and Verify JWT Encoded Data in Express

Aggregation in MongoDB is really powerful and allows you to create solid pipelines to extract and transform data. This is an introductory video that aims to demonstrate the basics of aggregation — we will see how to create some basic pipeline to extract data using `$match` and manipulate the output using `$project` stages.

The aggregation stages/operators covered in this video are:

* [`$match`](https://docs.mongodb.com/manual/reference/operator/aggregation/match/index.html)
* [`$project`](https://docs.mongodb.com/manual/reference/operator/aggregation/project/index.html)
* [`$concat`](https://docs.mongodb.com/manual/reference/operator/aggregation/concat/)

You can see the list of all the [available operators in the MongoDB docs](https://docs.mongodb.com/manual/reference/operator/aggregation/)


Find and Manipulate Data using Aggregation in MongoDB

In our last lesson, we learnt the basics of MongoDB aggregation and saw how we can [find and manipulate data](https://egghead.io/lessons/mongodb-find-and-manipulate-data-using-aggregation-in-mongodb). In this continuation, we will see how we can sort, skip and limit records during our aggregation stages.

The aggregation stages/operators covered in this video are:

* [`$sort`](https://docs.mongodb.com/manual/reference/operator/aggregation/sort/index.html)
* [`$skip`](https://docs.mongodb.com/manual/reference/operator/aggregation/skip/index.html)
* [`$limit`](https://docs.mongodb.com/manual/reference/operator/aggregation/limit/index.html)

You can see the list of all the [available operators in the MongoDB docs.](https://docs.mongodb.com/manual/reference/operator/aggregation/)
