Learn Hapi, Remix and Scikit-learn

[Supabase](http://supabase.com?utm_source=egghead&utm_campaign=remix) is a collection of open-source tools that wrap around a PostgreSQL database. In this course, we look at building a realtime chat application with Remix, using Supabase for db hosting, authentication, authorization and subscribe to realtime db events - updating the UI as the database changes.

We will learn about:

- loaders and actions in Remix
- querying and mutating data with Supabase
- authentication with GitHub
- authorization with RLS
- merging client and server state with realtime events
- deploying a Remix app to Vercel

This course is 100% TypeScript, however, don't stress if you don't have any experience with TS, as Supabase does most of the heavy lifting here! 🎉

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

hapi is a battle-tested, full-featured, framework for building web applications and services with Node.js. With integrated support for essentials like authentication, caching and validation, and a powerful plugin system, hapi is ideal for projects and teams of any size.

This course will introduce hapi, some of it’s plugins, and guide you through many of hapi’s core features.

A rich framework for building applications and services hapi enables developers to focus on writing reusable application logic instead of spending time building infrastructure.

Introduction to Node Servers with Hapi.js

View engines, or template engines, allow you to maintain a clean separation between your presentation layer and the rest of your application. This video will demonstrate how to use the vision plugin with hapi to enable template support.

hapi.js - View engines 

hapi does not support serving static files out of the box. Instead it relies on a module called Inert. This lesson will cover serving static files using Inert's custom handlers.

hapi.js - Serving static files

Routing is a fundamental aspect of any framework. In this lesson, you'll learn how to use path parameters in hapi's router. We'll also touch on how the router uses specificity to order routes internally.

hapi.js - Route parameters

hapi doesn't ship with logging support baked in. Luckily, hapi's rich plugin ecosystem includes everything needed to configure logging for your application. This video will introduce good, a process monitor for hapi, and good-console, a reporter for good that outputs to standard out.

hapi.js - Logging with good and good-console

hapi makes handling POST and PUT payloads easy by buffering and parsing them automatically without requiring additional modules or middleware. This video will demonstrate how to handle JSON and form based request payloads via hapi's route configuration.

hapi.js - POST and PUT request payloads

hapi's reply interface is one of it's most powerful features. It's smart enough to detect and serialize objects, buffers, promises and even streams. This video will demonstrate first hand how to use the reply method to send your data to the client, no matter the format.

hapi.js - Replying to Requests

Think of hapi's `reply()` function as "what you want to say" and the `response` object as "how you want to say it". While `reply` controls the payload sent to the client, the `response` object will allow you to control how the client interprets the payload by manipulating status code, content type, state and more.

hapi.js - Using the response object

hapi automatically responds with JSON for any error passed to a route's `reply()` method. But what if your application needs errors rendered in HTML? This lesson shows how to implement friendly HTML error messages using hapi extension events.

hapi.js - Friendly error pages with extension events

hapi supports request validation out of the box using the joi module. Request path parameters, payloads, and querystring parameters can be validated with joi's simple, yet powerful, notation. This lesson covers the basics of validating requests using joi.

hapi.js - Request Validation with Joi

hapi has built-in support for parsing cookies from a request headers, and writing cookies to a response, making state management easy and straight-forward. It even has built in support for cookie encryption and auto detects when a cookie contains JSON, parsing or stringifying automatically.

hapi.js - Managing State with Cookies

hapi is a rock solid server framework for Node.js. Its focus on modularity and configuration-over-convention makes it the perfect match for any size development team. This video will introduce you to hapi by showing you the bare minimum needed to run a hapi server.

hapi.js - Up and running

Instead of using middlware, hapi provides a number of points during the lifecycle of a request that you can hook-in to provide additional functionality, called "extension events". This lesson will give you an introduction to using extension events, and show how they can be used to manipulate the request or response in-flight.

hapi.js - Extending the request with lifecycle events

The first thing you do is install Remix! In this course, you start with a barebones Remix set up. In many situations you will start with a [Remix stack](https://remix.run/docs/en/v1/pages/stacks) but this course starts from the beginning.

Installing Remix is easy though, so you will finish this lesson by being introduced to a core Remix feature: data loaders.

Remix loaders are functions that only run on the server so you are safe to connect to databases, make API calls, and anything else you’d expect to do on a server. The data you return from these functions will be received into your components through `useLoaderData` hooks. 

We’ll see how to return static data from a loader and display it in a component. Along the way, TypeScript will complain about data that is coming into your component so we will fix that as well.


Load and Display Static Data with Remix loaders

Most applications need data persisted to a database. A really great way to manage data is through an (Object-relational mapping) ORM so you aren’t stuck writing SQL queries when you want to be building websites. 

Prisma is a modern ORM that lets you get started with a database in just a couple steps. It supports TypeScript to which you will take advantage of.

In this lesson you will initialize Prisma in your application and model out what a `Post` will look like. You’ll set a few properties that Prisma will manage (e.g. id, createdAt) and a few that you will manage. Prisma also comes with a studio that you can run to create and manage data super easily when you don’t have other means to CRUD that data (we don’t yet!).

Install and Model Data with Prisma

Now that you have a database running, you need a way to connect to it in your application. This is where Prisma client joins the fray and really shines. 

With Remix, there is a little bit of set up that we have to do to ensure that we won’t be opening extra connections to the database through Prisma. Through this set up you’ll learn about another important pattern in Remix which are services. 
You’ll create a db.server.ts service that will manage setting up the Prisma client. The folks at Remix have us covered with this code snippet that safely sets the client up for you. 

After creating the client, we will create another service `post.server.ts` that will expose all of the functions that you can use throughout your application to retrieve data from the db. One great benefit of this pattern is that when consuming these services you don’t need to know about the implementation that is powering them. Just the api that is exposed, in this case a `Post` type and `getPosts` function.

FINALLY you’ll consume that function in the data loader at the root of your application to display posts from the database.

This sounds like a lot but you get this all done in under 5 minutes.

Retrieve and Display Data from the Database through Prisma and Remix Loaders

There are many ways to style an application. While styling isn’t a focus for this course, we don’t want the application to be unbearable to look at. 


TailwindCSS is how you will style this application. With it’s utility classes, Tailwind stays out of the way once you get it set up. The [Tailwind docs have a great tutorial](https://tailwindcss.com/docs/guides/remix) which you can follow to get to styling your application. You can also follow along in this tutorial.

Set up Tailwind and Create a Presentational Component in Remix

This is where things start to get fun, you’re adding data to your database!

 To do this, you’ll learn about Remix actions. A Remix action utilizes HTML elements to accept input from the user. When creating data, you’ll set the form to a method of `post`. The form needs a route to post to so you will need to set the `action` to the route that will handle the request. In our case it is the index route the form is in.

The Remix action itself accepts a request that you can pull the form field data you need off of it. From here you can update your database directly, because you’re on the server! In this case, you’ll create a function createPost that will utilize Prisma to create a record. Once this happens, we will redirect users back to the index page that they were on.

Add Data to your Database through Remix Actions and Prisma create

At this point, your form will accept any type of input that users desire. This isn't good, you need to add form validation. 

Form validation is another area that there are many ways to accomplish what you need. One great way to get easy form validation is through a library called Zod. Zod allows you to create a schema to parse your form input against. It will return form and field errors when input doesn’t match the rules that you supply.

With Zod in place, you’ll check form input in the action previously defined. If an error is found, you’ll return an object passing in the errors you find as well as the input that users submitted. This will be used to render error messages in the form and reset form state to what was submitted. This is easy to accomplish with Remix json helper that will also set the error message for you.

Along the way you will also see how easy it is to type this data.

Validate Form Data Through a Remix Action using Zod
