Learn Netlify, Postgres and Sequelize

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.

You've got some practice with using SQL to select, update, and join database tables.

But perhaps you've found yourself with a sneaking suspicion that you could be more efficient with your PostgreSQL.

Does your query seem slow?

A lesson on how to profile queries will point you in the direction of a fix.

Are you performing multi-step operations one at a time that are susceptible to errors?

The "all or nothing" transaction is the cure.

These are just a couple of examples of the techniques, tips, and tricks that Tyler Clark has learned in his years of experience working on large scale production applications.

Other topics in this course include working with CSV files, different techniques for aggregating & filtering, and more!

Advanced SQL for Professional Developers

How does e-commerce work on the Jamstack? 

Jason Lengstorf and [Thor 雷神](https://twitter.com/thorwebdev) teamed up on _Learn With Jason_ to [build a serverless Stripe Checkout implementation](https://www.learnwithjason.dev/sell-products-on-the-jamstack). This collection is a cleaned up, egghead-style tutorial for selling products on a Jamstack site using Netlify Functions and Stripe Checkout.

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.

OpenGraph images are the images you see when you paste a link into a social platform and it "unfurls" into an image, title, and description. This happens on Twitter, Discord, Slack, and many other platforms. This collection goes over everything from designing OpenGraph images in Figma, to implementing them in CodeSandbox, to returning headless browser screenshots from Netlify Functions, and finally using Cloudinary as a write-through cache. 

You will come away from this collection with the ability to ship an API that you can use on any of your sites, and also on-demand, that can generate images for not only OpenGraph unfurls, but also for Instagram, GitHub, and more. Using headless browsers with playwright to generate our images means we get full access to all the responsive power of CSS and all the logical power of JS to handle layout, importing assets like pngs, choosing different fonts, and more.

Most applications rely on databases to store data. Understanding how to create a database and communicate with it unlocks a critical power in your web development career. 

In this course, Tyler presents all the building blocks of creating and interacting with a PostgreSQL database. From creating a brand new table, up through organizing and aggregating data across multiple tables, you will learn the fundamental skills of SQL — and you’ll be prepared to apply them right away.

After completing this course, you’ll be ready to tackle more challenging SQL topics like proper data modeling, normalizing data, and exploring different database types.

SQL Fundamentals

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.

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.

You know the basics of Postgres, but most meaningful queries will require you to combine tables in novel ways to ask questions you couldn't ask with a single table alone. Joins and unions come up over and over again in interview questions -- because of how fundamental they are. This course will make you a master of your tables, and give you the power to answer questions you couldn't before. 

Understand Joins and Unions in Postgres

In this course we will show you how to wield the power behind the elusive window function. Which five movies were the highest grossing each year? Who are the highest performers in each department relative to their peers? These questions ask us to partition records into subgroups and answer questions about those groups -- that’s the power of a window function. 

Many programmers will reach for their favorite scripting language to solve problems like these, but window functions allow you to answer them with the speed and efficiency of the Postgres query planner.

Plus, with the power to further slice and dice this derivative information, there’s no limit to the questions you can answer with raw SQL.

It’s amazing how much you can accomplish with a basic knowledge of SQL. In this course we’ll learn how to store lots of information (many millions of things!) and answer nearly any question we might have about that information (on the order of milliseconds!) 

We’ll learn enough to make you say you “know SQL” -- table creation, inserts, selects, updates, deletes, aggregations, indexes, joins, and constraints. Along the way we’ll model real world problems so that you can see just how powerful SQL will make you!

Creating tables is actually quite simple. However before we go creating tables we need to first understand the data we want to store. To make sure our data scales appropriately we need to break down the data into its smallest form so we can easily add data and read from it.

Create a Table with SQL Create

Tables in databases are not worth much value if they do not actually hold data. In this lesson we will use the insert statement to add rows of data to our table. We'll break down each component of the statement and review what is required for a successful insert. 


Add Data to a Table with SQL Insert

Databases are not really good for anything if we are not able to get the data out. By using the select statement, we can pull out all of the data within our database table. Let's work with different queries that pulls out all of our columns, just some of the columns, and even filters out duplicate column values. 

Query Data with the Select Command in SQL

One of the core commands in SQL is update. This is how we can modify the data that is already in our database table. Let’s update our users table and change one of our user's duplicated user handle to a new UUID. We'll even use a postgres extension to generate new UUIDs.  




**UUIDs / GUIDs**

*Postgres* - http://www.postgresqltutorial.com/postgresql-uuid/

*SQL Server*- https://docs.microsoft.com/en-us/sql/t-sql/functions/newid-transact-sql?view=sql-server-2017

*MySQL* - https://dev.mysql.com/doc/refman/8.0/en/miscellaneous-functions.html#function_uuid

*Oracle* - https://docs.oracle.com/javase/8/docs/api/java/util/UUID.html




Update Data in a Table with SQL Update

Deleting data within our table is easily done by using ether the delete, truncate, or just dropping the table altogether from our database. Let’s remove a user from our table using the delete command, remove everyone with truncate, then drop the entire table with the drop command. 

Removing Data with SQL Delete, Truncate, and Drop

SQL gives us the power to choose what data we pull out of our table. We will use the where clause within our select statement with many operators. These include the greater than, less than, equal, and not equal. We will also use some special operators such as "in", "between", and "is". 

Conditionally Select out Filtered Data with SQL Where

Another powerful SQL skill is understanding how to group rows together by column values.  Once the data is grouped together, it can be difficult to understand how to actually work with the groupings. In this lesson, we will use the group by clause, as well as the count, sum, avg, min, and max aggregate functions. 

### Counts with create date and first name example: 
```sql
SELECT u.total, u.create_date, first_name 
FROM Users us 
INNER JOIN (SELECT count(create_date) AS total, create_date 
   FROM Users
   GROUP BY create_date) u ON u.create_date = us.create_date;
```

### Min create date with first name example: 
```sql
SELECT create_date, first_name 
FROM Users 
WHERE create_date = (select min(create_date) FROM Users);
```
### Aggregate functions:

https://docs.microsoft.com/en-us/sql/t-sql/functions/aggregate-functions-transact-sql
https://docs.oracle.com/database/121/SQLRF/functions003.htm

Select Grouped and Aggregated Data with SQL

When working with database tables, we want to make sure we keep our data as simple as possible. This can sometimes mean having multiple tables that share some data columns. Using the join statement, we can combine data between two tables on similar column data to gather more information in one query. Let’s work through some common join statements like left, right, inner, and cross join. 


Combining Tables Together with SQL Join Statements

This course is designed to take someone that has no experience with relational databases and teach them how to at least create, read, update, and delete. We'll explore many different aspects of SQL and what makes working in relational databases easy. This video also goes over how to install postgres on your machine so you can follow along.
