Learn Aws, Jest and Serverless

You're going to find cloud services being used at nearly any enterprise you work for. So it's important for us developers to at least have a high-level understanding of this infrastructure.

And since AWS has the dominant share of the cloud market, being familiar with it is incredibly valuable and opens a lot of doors.

But gaining that familiarity isn't easy. Just browsing through the list of 200+ services is overwhelming. 

Getting started with learning AWS usually involves having a dozen or more open tabs and the feeling that you're going down a rabbit hole that never ends.  

This course is an alternative to that stress. It has been structured like a boat tour on a river of knowledge, linearly guiding you through the core of AWS. 

By the end of this course, you will be confidently spinning up servers, creating relational databases, storing static assets, and writing serverless functions with confidence. 

So, whether you need to learn AWS for your current job or are looking to earn your cloud practitioner certification, start watching this course and gain the skills you need today.

Amazon Web Services (AWS) is a powerful expansive cloud infrastructure platform for building modern web applications.

AWS provides services for data, presentation, authentication, security, video encoding, and much more. Offering over 175 fully-featured services from data centers globally, AWS powers a large percentage of the internet.

Cloud Infrastructure Fundamentals with AWS

In this course, we'll build a video course platform using the AWS Amplify Admin UI. 

The Admin UI provides simple yet powerful tools to model database tables, add authentication and authorization, and manage app content, users, and groups. It also offers the ability to manage the application users and content. 

The AWS Amplify Admin UI focuses on data types rather than backend infrastructure. 

All the backend resources generate infrastructure as code (IaC) templates that can be committed in the team repository and integrated with AWS Amplify continuous deployment workflow to manage the different environments.

Before taking this course, you should have a basic understanding of React Hooks.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Starting from a prebuilt frontend, Jason Lengstorf guides you through the creation of a "Corgi Up-boop App" that uses Netlify Functions and Hasura. You can view [the deployed final product on Netlify](https://egghead-serverless-functions.netlify.app/).

You'll set up the Netlify CLI, and configure a local development environment before writing and deploying functions with a few different use cases.

The first example function bypasses CORS restrictions to retrieve corgi data from an example third-party API.

Next, you'll configure environmental variables to securely communicate with the Unsplash API without exposing private keys to the client.

Serverless functions don't persist data by themselves, so we will use  Hasura to create a GraphQL API for tracking the number of "boops" each corgi receives.

This course is an excellent illustration of the speed of Serverless functions, and how fast you can implement functionality in your web applications.

An all-in-one workflow that combines global deployment, continuous integration, and automatic HTTPS.

Amazon AWS is one of the most popular cloud providers in the world, but it can also be daunting to learn thanks to the alphabet soup of service acronyms.

Once you've figured out which subset of services to use, you've got a lot of clicking around to do in order to get things configured.

Not anymore!

With the AWS Cloud Development Kit (CDK), you are able to configure AWS services from your terminal & editor.

Even better, you can do your configuration, frontend, and backend all with the same language. 

In this course, Tomasz Łakomy will guide you through using TypeScript to complete the lifecycle of an application powered by AWS CDK. You'll see how to start a project, develop it locally, deploy it globally, then tear it all down when you're done.

The services & development approach Tomasz demonstrates in this course are used by countless companies around the world.

We generally tend to avoid paying for things unless we actually need them, and the same goes for AWS

When using a cloud provider like AWS sometimes an unexpected charge may occur and we'd like to understand what are we being charged for and how to be notified whenever an unexpected charge occurs (especially when we're trying to stay within a free tier).

In this quick (4 minutes, 2 lessons) collection we're going to learn how to:

- Review the AWS Billing & Cost Management Dashboard
- Set up a billing alarm to be notified whenever our bill is larger than $5
- Review the AWS bill to understand how much are we going to pay this month and why

Use AWS Billing & Cost Management Dashboard to keep your AWS bill to minimum

Learn AWS DynamoDB from scratch

This collection includes introductory level material for AWS DynamoDB. We cover what DynamoDB is, when you'd use it, and the vocabulary you'll need to understand documentation and talks in the ecosystem.

You'll come out of this playlist with the ability to understand what people mean when they say DynamoDB and the base you need to get started yourself.

Intro to DynamoDB

Building larger serverless applications can be tricky - creating many lambda functions as well as other resources such as DynamoDB tables, S3 buckets, API Gateways using AWS Console takes quite a lot of time. Not to mention other problems such as redeploying the app to a different region, reviewing the infrastructure etc.

**AWS Serverless Application Model** (**AWS SAM** for short) simplifies a lot of those issues 🤩

Built with with best practices in mind, SAM allows you to:

🌟define your infrastructure as code using a YAML template (which can go through code review!)

🌟define resources such as lambda functions, DynamoDB tables etc. in a much simpler way than doing it directly in CloudFormation (which SAM is built on top of)

🌟build and deploy a serverless application from a command line

🌟debug and test lambda functions locally using SAM CLI

🌟debug and test lambda functions from WITHIN your editor with AWS Toolkit extension


Add AWS SAM to your toolkit with this quick collection!

Build serverless applications with AWS Serverless Application Model (AWS SAM)

This playlist covers all of the ways to use the node.js DocumentClient to interact with one or more DynamoDB tables.


note: We do not cover scan() as it is not recommended for most usage and if you need it you'll know how to read the documentation to use it by the end of this collection.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

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.

React makes it intuitive to build real-world web application. But in reality, you need to use a host of other services to get the app in front of real users. 

This course walks you through setup and implementation to get your cloud-based application up and running. 

You’ll learn to set up:
* a new project in AWS Amplify configured to your React app
* user authentication with Amazon Cognito 
* managed GraphQL with AWS AppSync
* image storage and retrieval with Amazon S3
* text translation via Lambda functions
* and finally, deployment of your application on AWS using Amazon S3

You’ll finish the course ready to quickly and easily deploy your serverless React application, so users can start using and enjoying it right away.

React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.

Building Serverless Web Applications with React & AWS Amplify

With GraphQL, you can define the shape of your data in a schema, and GraphQL will fulfill the request with the precise data you need. When you need it. This doesn't come without a cost. GraphQL adds a lot of complexity to your application by requiring you to define your schemas through types, mutations, and resolvers.

AppSync is a fully managed serverless GraphQL service that fast-tracks your API development. You can define a single type, and AppSync auto-generates a schema, queries, mutators, and subscriptions for you.

In this course, Nader Dabit will show you how to:

- build a production-ready GraphQL API through AWS AppSync
- create and modify data through the AWS AppSync console
- connect a React application to the GraphQL API
- execute queries, mutations, and subscriptions for data through the API in React

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

In this collection, we build a minimal flashcard application using React, primarily focusing on function components and the hooks API. To make sure we can understand and maintain existing code, there are also a few lessons toward the end that use class components so you can get familiar with the syntax. We cover important React concepts, and sprinkle in libraries that are pretty standard in the ecosystem like @reach/router, Jest, and React testing library. We start with create-react-app so we can get right into it without worrying about configuring tooling. There's [a separate course for that here](https://egghead.io/courses/modern-javascript-tooling-with-react?af=5mx0ie)

AWS Lambda, Serverless, FaaS - there is a lot of noise around those topics online (and for a very good reason!) and it can get confusing at times 🤯

In this collection we're going to take a look at AWS Lambda from scratch, in order to get **YOU** from:

"_I have no idea what a lambda function is_" 

to 

"_I know quite a bit about AWS Lambda, and I'm going to use it to solve my problems_"

Learn AWS Lambda from scratch

The core of serverless architectures are auto-scaling systems and a pay-per-execution pricing. Two traits that allows developers to significantly reduce operational cost and complexity, by outsourcing infrastructure management to cloud providers and focus on building business logic.  

In this course we walk through the basics on how to create a serverless API. We start off creating a simple HTTP endpoint. Then we build the first two endpoints of a REST API for a simple Todo Application backend storing the data in DynamoDB. After watching this course you will be ready to get started building you first serverless backend.

In this course we are going to work through properly setting up Enzyme with Jest to test rendered components. This includes the nitty gritty of making our testing environment work with various versions of React. After we get our environment setup ready, we’ll work through the different ways we can render a component within our test pages. With a rendered component we can now test component methods and properties to assert that they are what is intended. 

Test React Components with Enzyme and Jest

End-to-end testing assures you of a few things: that all the integrated pieces of an application properly function, all those pieces work together as expected, and your tests include and simulate real-user scenarios — something unit and integration tests just don't do.

This course introduces you to two great tools for E2E testing: 

* Puppeteer opens and runs applications in a Chromium browser and performs the actions it's given.
* Jest asserts that the integrated pieces work as expected and that add-on libraries like Faker and pixelmatch take our tests to the next level.

Over 9 lessons, we will create common application features and use Puppeteer and Jest to run different types of tests against them. You'll get practice using these tools to render content, mimic user activity, automate tests, and measure the overall performance of your application.

The videos in this playlist will get you started building serverless applications using AWS SAM. It covers

* Setting up your AWS credentials
* Building and deploying a Lambda
* Testing your Lambda locally
* Cleaning up your AWS account once you've finished

Introduction to AWS SAM

AWS Amplify allows developers to create, configure, and deploy Serverless APIs and functions directly from their front-end environment.In this collection, you'll learn how to deploy various types of APIs and functions using the Amplify CLI. You'll also learn how to share code among various functions using Lambda layers and schedule functions to run at an interval to implement Serverless cron jobs.

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.
