Learn Express, Faunadb and Reactfire

As developers, we have a responsibility to protect the data our users trust us with. No one wants to wake up to the news that their site was hacked and all of the user accounts stolen.

Security is important, yet it is often overlooked and forgotten.

Part of the reason for this is that security seems hard to get right. This results in developers crossing their fingers and hoping for the best.

In this course, you'll learn how to protect your application by learning how to attack it.

Web Security Essentials: MITM, CSRF, and XSS

Express is a well-known and supported framework for Node web applications. It provides a lot of excellent functionality to process requests, interact with other APIs, handle authentication and return appropriate requests for any client.

This collection will look at providing an API for a specific application but will explore concepts that will be helpful in building a wide variety of applications.

Building an API with Express

Modern applications know how to keep users informed of realtime updates through notifications, popups, and other messages.

On the development side, the ability to not only create web apps but have them communicate in realtime is a quirky, standout skill for your resume. It’s interesting, useful, and powerful.

In this course, Mark Barton will show you how to use Socket.io to facilitate bi-directional client-server communication and notifications using Vue on the frontend. Socket.io is a JS library that connects a client-side library to a node.js server. In the course, you’ll see how to use Socket.io to broadcast simultaneously to all or targeted clients based on filters you set up — so the right people see the right message at the right time.

You’ll learn to set up and connect Socket.io with node.js and Vue, and you’ll get practice making informed, complex architectural decisions around realtime broadcast messaging.

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Vue and Socket.io for Real-Time Communication

Learn how to build a simple REST API to store notes using the latest built-in node features including native ES modules, the fs/promises API, async/await, the nullish coalescing operator, and destructuring. No compilers, no build steps, pure code.

This collection of lessons is great for beginners to Express as long as they are familiar with JavaScript and the HTTP protocol. Those more familiar with node and express will appreciate a fast-paced, modern take on using these popular tools and will likely benefit most from the lessons on input validation, models (which emphasizes a lot of new syntax), using fs/promises to serialize a `Map`, and accessing asynchronous data with `async/await`.

Pre-requisites:

- [Install curl](https://curl.haxx.se/)
- [Install node 14](http://nodejs.org/)
- Be familiar with the terminal

View the source for this project in the [project's github repo](https://github.com/xjamundx/egghead-express).

**Notes**:

- I'm not very pedantic about REST and basically just mean an API over HTTP
- [Express 5](https://expressjs.com/en/guide/migrating-5.html) is still in alpha (and has been for over two years), but most of these lessons apply to Express 4 as long you use something like [express-async-errors](https://www.npmjs.com/package/express-async-errors) to add support for `async` routes and middleware

Build a REST API with Express 5 and node 14

This application serves as an introduction to building products with a JAMStack and Serverless approach. We cover everything from the beginning:

* starting with the Gatsby client
* handling authentication with Netlify Identity
* Shipping a GraphQL server on Netlify Functions
* Building in access control with a serverless capable database

It uses tools that remove as many of the barriers as possible while also allowing upgrading in the future. Netlify Functions can grow into AWS Lambda, Netlify Identity can grow into Auth0 or Cognito, and FaunaDB can grow into DynamoDB.

Gatsby is a blazing fast static site generator built with React. Gatsby gives you all of the modern JavaScript tools you want; set up and ready to go out of the box.

Building a Serverless JAMStack Todo app with Netlify, Gatsby, GraphQL, and FaunaDB

This collection is a sequel to the [Building a Serverless JAMStack Todo app with Netlify, Gatsby, GraphQL, and FaunaDB](https://egghead.io/playlists/building-a-serverless-jamstack-todo-app-with-netlify-gatsby-graphql-and-faunadb-53bb) collection. In this collection we take the TODO application we built and convert it to run using Netlify Identity, AWS Lambda (using the serverless framework) and DynamoDB. We cover

* Fauna vs DynamoDB and when to use each
* Setting up AWS accounts
* Creating DynamoDB tables and data modeling differences between Fauna and Dynamo
* Converting our Netlify Functions deployment to a Serverless Framework deployment
* Implementing Custom authorizer functions on AWS

It uses tools that remove as many of the barriers as possible. Netlify Functions grows into Serverless Framework adn AWS Lambda, Netlify Identity is kept around, and FaunaDB can grows into DynamoDB.



FaunaDB is a global serverless database that gives you ubiquitous, low latency access to app data, without sacrificing data correctness. It eliminates layers of app code for manually handling data anomalies, security, and scale, creating a friendlier dev experience for you and better app experience for your users.

Converting a Serverless App to run on AWS Lambda and DynamoDB with Serverless Framework

While this course is for IBM Domino Developers who are looking to utilize Node.js alongside their applications, or Javascript developers looking to integrate with a Domino server. There are quite a few tips and tricks you can learn for integrating Node.js as a proxy server for any REST API you might want to communicate with your JavaScript Application.

We cover how you can continue to use cookies provided by IBM Domino for user authentication and authorization while accessing a Node.js / Express based application, including modifying the standard login form to expose authentication errors.  

We show how to store user level information inside a JWT giving the option to store functional levels of access safely.  This stateless token can then be decoded server side to list what user roles a user has and therefore can restrict functionality without having to refer back to Domino each time.

The course will demonstrate Create, Read, Update and Delete methods using the Domino Data Services all via the NodeJS application but still maintaining Domino security.

And finally, we show how you can reuse Domino generated HTML inside a handlebars template by scraping and manipulating the HTML.

Integrate IBM Domino with Node.js

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.

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

FaunaDB is a global serverless database that gives you ubiquitous, low latency access to app data, without sacrificing data correctness. It eliminates layers of app code for manually handling data anomalies, security, and scale, creating a friendlier dev experience for you and better app experience for your users.

Fauna is inspired by [Calvin](https://blog.acolyer.org/2019/03/29/calvin-fast-distributed-transactions-for-partitioned-database-systems/), has [built-in GraphQL integration](https://docs.fauna.com/fauna/current/api/graphql/), and a query language based on lambda calculus. Be sure to check out the [Jepsen analysis](https://jepsen.io/analyses/faunadb-2.5.4) and the associated [chart of consistency models](https://jepsen.io/consistency)

Nodejs

Express is a minimal web server built on Node.js that provides essential functionality for delivering web applications to the browser and mobile devices. This series will guide you through the first steps of using Express for building your own applications.

Getting Started with Express.js

In this lesson you will learn how to support data modification by handling HTTP verbs besides GET. We will look at how to edit, save, and delete content with `.put` and `.delete`.

Save and Delete Content in Express with HTTP Verbs

Streams are a big part of Node's famous non-blocking I/O, and Express lets you take full advantage of them. This lesson demonstrates how to integrate streams into your server to improve performance and simplify your code. 

We will look at `.creatReadStream`, `.createWriteStream`, and `.pipe`  to read and write from streams. 

Use Streams in Express

Sometimes you just need to serve existing files. In this lesson we'll examine how to use functionality built into Express to do just that.

Serve static files with express

As your application grows, it's easy to end up with a long list of route handlers and helper functions. In this lesson we'll look at strategies for keeping things organized and manageable.

We will move individual subpaths into their own file by using `.router` to create an instance of the Express router.

Organize Code by Subpath in Express

High availability apps require that no distinction be made between local and remote services. Attached resources should be accessed by environment variables, and in doing so allow you to swap out one attached resource for another. 

In this lesson we will setup a reverse proxy that directs image path requests and routes them through a defined server URL. By doing so, we decouple server requests for images which allows for easy switching from locally-served image assets to a CDN by simply updating an environment variable.

Proxy Requests for Local and Remote Service Parity

This lesson will walk you through replacing the app's file system reliance with a live MongoDB database. We'll also use a popular ORM library to manage our database operations.

Integrate MongoDB into your Express App

Template engines allow you to define your UIs in a declarative manner while maintaining a dynamic, data driven presentation layer. This lesson will demonstrate how to use template engines that have built-in support for Express as well as engines without explicit Express support.

Use Template Engines with Express

Routing is a fundamental aspect of Express. This lesson demonstrates how to define dynamic routes and access route parameters in your code.

Define dynamic routes through Express

In this lesson we will initialize our Express application using  `npm init`. 

After loading express through npm we will look at a couple basic functions Express exposes to us such as `.get` and `.send`. This will allow basic interaction via the url.

We will also see how using a package like `nodemon` can allow for rapid iteration when developing an application.



Create a Basic Server with Express

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