Learn Mdx, Nginx and Svgo

In this course, we will dive into a number of different ways we can create, optimize and integrate an SVG icon set. There are pros and cons to each method, so we’ll dissect each approach so you can make an informed decision for your project. We will learn how to use build tools to automate the process of creating, manipulating and optimizing icons. We’ll take a look at how to use CSS to manipulate styles on an SVG and even how to integrate your SVG icons in a React project.

Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files.

MDX has grown rapidly since the first commit two and a half years ago. We'd like to celebrate our accomplishments so far, and talk about what lies ahead. We've got lots of plans.
Learn how MDX increases developer productivity, improves educational content authoring, and even peek behind the curtains to see how MDX works.

MDX is an authorable format that lets you seamlessly use JSX in your markdown documents. You can import components, like interactive charts or notifications, and export metadata. This makes writing long-form content with components a blast.

Just like a bitmap image, you can compress an SVG by removing various pieces of code that aren’t necessary to it rendering properly. This reduces file size & download time, ultimately leading to a faster page load speed. You’ll learn how to automate the process of compressing your SVGs using `svgo` in the command line.

For a full list of options and plugins available to use with `svgo`, [check out their documentation](https://github.com/svg/svgo).

Note: This lesson assumes you have `npm` installed.

Optimize SVGs for Better Performance using svgo

In this lesson, we’ll explore the process of combining all of your SVG icons into one SVG sprite, to be included directly into markup. We’ll use the command line, along with the `svgo` and `svg-sprite-generator` npm packages to automate the process of compressing the SVGs and creating the sprite.

_Note:_ This lesson assumes you have `npm` installed.

NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server.

Learn about the concepts of managing data within Docker volumes, including all of the commands to create and manage volumes. We'll demonstrate how to mount a Docker volume to one or many containers by creating and mounting a volume to an Nginx proxy, and then verify the output with curl. You'll also see how changes to files within volumes of one container propagate to other containers with the same volume mounted, and learn various commands to inspect Docker volumes.

Manage Data within Docker Volumes

Learn how to setup an Nginx proxy server with Docker that sits in front of a Node.js app. You can use a proxy to control the flow of frontend requests hitting your app, as well as to achieve better performance and scalability. We'll create a sample Node.js app, configure a default Nginx configuration file for proxying web requests, build both Node.js and Nginx Docker images, and learn how to link everything up and get it running with Docker specifics.

Setup an Nginx Proxy for a Node.js App with Docker

Node.js apps built with Docker cannot scale horizontally by themselves. In this lesson we will spawn out multiple Node.js processes/containers, and move the incoming request handler to an Nginx proxy to load balance and properly scale our Node.js app.

Cole Bemis explains how MDX works by taking us though his own journey digging into what MDX does under the hood.

Demystifying MDX

Laurie Barth walks us through MDX v2's syntax by trying to break it. She starts at markdown syntax and takes us through increasingly complex applications of MDX, including passing dynamic props to .mdx files imported into other .mdx files.

Monica Powell, creator of React Ladies, talks through why someone would migrate from Remark to MDX before going into how to do that and what problems you might run into.

This lesson will focus on creating the checkbox styles for both the default and checked state. We'll make sure our styles are accessible and able to use our theme system.

We'll get started by adding an inline SVG to our input which we can style. I'll give you a tour of what is happening with the SVG and show you how to display it in the checkbox by providing a width. From there we will set the default state of the SVG to a `scale(0)` and set up a transition so when the checkbox is clicked to scale the SVG to 1.

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.

node

Ghost has two hard dependencies which need to be installed before it can run. Those are Nginx and Node.js.

We will start by installing Nginx and set Nginx up to control the traffic coming into the EC2 server. After this, we'll install NVM using the raw install script that they provide on GitHub. With NVM installed we can then install the latest version of Node.js

Next.js is a minimalistic framework for server-rendered React applications.

One cool aspect of Next.js is its [fast refresh](https://nextjs.org/docs/basic-features/fast-refresh) support. Whenever you change some Next.js component it automatically refreshes the page without hard reloading everything. However, you might notice that whenever we change something within our MDX markdown files, fast refresh is not capturing that, hence we need to manually refresh the browser window.

In this lesson, we learn how to leverage a feature of Nx to create a "[custom Next.js development server](https://nx.dev/l/r/next/server#customserverpath)". We are going to use [chokidar](https://www.npmjs.com/package/chokidar) to watch our articles folder and then invoke a private API on the Next.js server instance to trigger a reload command.

When rendering our markdown we might want to enrich the experience with some dynamic content. Many static site generators allow to include dynamic content placeholders for like embedding a Youtube video, generating table of contents, code blocks with interactive functionality and more. One way to achieve this in the React ecosystem is by using MDX. MDX is similar to JSX but for Markdown content, and allows us to directly embed React components within it. This gives an enourmous flexibility to what we can display within a page.

In this lesson we’re going to generate a new Nx library to host our “mdx elements” and learn how to leverage the `MDXRemote` component to embed these React components into our markdown rendering flow.

Embed React Components in our Markdown with MDX in a Next.js App

Many markdown documents have a metadata section at the very beginning, which contains information such as the title, author and creation date. This section is the so-called "front matter". 

In order to render our markdown-based blog articles on our portfolio site we want to parse them and separate them into the front-matter and main article part. `gray-matter` is a library that helps us with that.

Parse a Markdown Document With gray-matter

By leveraging the [dependency graph](https://nx.dev/l/r/structure/dependency-graph), [Nx](https://nx.dev) is able to understand which parts in the monorepo changed and thus trigger actions on those nodes, such as building an app, running tests or linting. This already works out of the box. However, with our portfolio application, all of our markdown articles reside in the root-level `_articles` folder. Those are not captured by the Nx dependency graph and thus Nx would not correctly detect a change to our Next.js site application whenever we change or add a new markdown article.
In this lesson, we learn how to register our `_articles` folder s.t. it appears as a dedicated node in the Nx dependency graph.

Register our Markdown Articles with the Nx Dependency Graph

Next.js is all about creating performant web applications. However, the more React components we pull into our MDX via `next-mdx-remote`, the heavier our JavaScript becomes which drains our site's performance. Also, while we might have quite a few React components to be included in our Markdown rendered content, we might not always use all of them in our articles.

In this lesson, we learn how to leverage Next.js dynamic imports to just pull the minimum necessary components into our final JavaScript bundle. Also, we look into why we might want to do deep imports into our Nx library setup to decrease the size of the bundle even more.
