GitHub Tips & Tricks

JavaScript community has been shaken recently by a release of Svelte 3 and for a good reason - it's a completely different approach than React or Vue. To quote the docs:

"[Svelte](https://svelte.dev/) is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app."

**The best part?** If you have 26 spare minutes you can learn the basics of Svelte 3 and start building your own apps with it!

Enjoy!



The magical disappearing UI framework

 - The web's JavaScript bloat crisis, solved. Svelte turns your templates into tiny, framework-less vanilla JavaScript.
 - Simple and familiar. Build apps out of composable, easy-to-write blocks using languages you already know.
 - Super fast, rock solid. Compile-time static analysis ensures the browser does no more work than it needs to.

Github Actions are an awesome tool from Github that allows us to automate tasks using code-based workflow configuration files. There's also a large marketplace that comes stocked with many useful tools that are ready out of the box.

But sometimes the options available don't completely solve our needs or maybe we're working with a new technology that's simply not available as an Action yet. Luckily, Github allows anyone to create their own Actions using common technologies like Javascript via Node.

We'll learn how to create a new Javascript-based Github Action running on Node. We'll first walk through a simple Hello World example, learn how to test it locally, version control it, use it in the wild, and move on to more advanced solutions that include using packages from npm!

SSH provides a secure way for your to [connect to and authenticate with GitHub's servers](https://help.github.com/en/github/authenticating-to-github/about-ssh). While HTTPS connections use usernames and passwords as credentials, SSH instead uses public and private key pairs. These can be generated on your system using a CLI like [`ssh-keygen`](https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent) and then associated with your GitHub account using the public key.

In some cases, you may need to connect to more than one GitHub account from the same system. For example, you may have [separate accounts for personal and professional projects](https://ryanharris.dev/managing-ssh-keys-for-github/), which can be difficult to manage manually. Using `ssh-agent` and a SSH configuration file, you can alleviate this pain point by automatically determining which key to use based on your GitHub repository's `git` URL.

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script.

GitHub Actions are a powerful workflow tool that allows you to write and use custom code to execute workflows. It's like a serverless CI/CD platform built directly into GitHub. We have access to GitHub's registries, our own repos, multiple platforms (Mac, Windows, Linux), runtimes (VMs and Containers), and languages (JS, Rust, Go, etc) to perform any action we want. We can trigger workflows using GitHub's own events, our custom events, or even scheduled events like a cronjob.

Publishing a JavaScript library for public use requires some extra steps. You need to think about how people will use the library. From end users, to contributors your library now has a variety of people outside of yourself potentially making use of the code that you've released into the wild.

From Github and npm, to releasing beta versions, semantic versioning, code coverage, continuous integration, and providing your library with a solid set of unit tests, there are a ton of things to learn.

This series will guide you through a set of steps to publish a JavaScript open source library.

Web accessibility (also referred to as a11y) is the design and creation of websites that can be used by everyone. Accessibility support is necessary to allow assistive technology to interpret web pages.

React fully supports building accessible websites, often by using standard HTML techniques.

Erin Doyle is an expert in creating accessible React applications and has developed a course that will give you a concrete process for auditing react apps for accessibility. In this course, you will go through different tools and libraries to audit components in a React app.

Fast, easy and reliable testing for anything that runs in a browser.

Creating forms is one of the simplest and most complicated things at the same time. A basic form consists of many different things happening, we have to retain the value, we have to keep watch of validation and we have to show error messages when something is invalid, this is on both the fields and on the entire form itself if we send a request off to the backend service.

So we're going to create a form using just the normal svelte features. Then we'll look into creating a form using the svelte forms lib.

npm is the package manager for JavaScript. Find, share, and reuse packages of code from hundreds of thousands of developers — and assemble them in powerful new ways.

npm packages almost always have a git repo tied to them for version control. We will start our package by initializing a git repository.

Add version control to npm packages using git init

NVDA (NonVisual Desktop Access) is a free “screen reader” which enables blind and vision impaired people to use computers.

nvda

NVDA is a popular open source screen reader on Windows that works well with Firefox. It's similar to JAWS, another popular Windows screen reader that works best with IE. But NVDA has no licensing fee plus an open bug tracker, making it great for users as well as developer testing. 

In this lesson, you'll learn how to browse a webpage using NVDA's keyboard shortcuts, including headings navigation, skip links, and the Elements List. You'll also learn a bit about Forms Mode and how it impacts screen reader navigation.  For more tips, check out the resources below.

In this lesson we’ll talk about what GitHub is and how to sign up for a GitHub account so you can contribute to an open source project on GitHub.

Introduction to GitHub

GitHub adds a lot of great features on top of git repository hosting. We’ll take a look at some of these features including:

- How to create a repository and organization on GitHub
- How to explore and find projects on GitHub
- About GitHub gists
- Searching pull requests and issues on GitHub

Exploring GitHub

The basic unit of GitHub is a repository. This is where your code is stored and GitHub allows you to interact with others and with the code in great ways. In this lesson we talk about Watching, Starting, and Forking a repository. We also cover GitHub issues and pull requests and various other stats about a GitHub repository.

Exploring a Repository

Let’s install the Git Source Control Management software so we can interact with repositories hosted on GitHub.

How to install Git SCM

Anytime you push code to GitHub, you must be authenticated so GitHub knows you are authorized to make changes. In this lesson we’ll learn how to authenticate with GitHub using SSH so we don’t have to enter our username and password each time we push code to GitHub.

How to authenticate with GitHub using SSH

When you find a bug in an open source project, you know exactly the change you want to make. Other times you just want to find a way to contribute. Either way, you’ll need to know how the project maintainers want to run the project and work with them to come up with an implementation for the fix/feature. And if you don't even know what project to start contributing to, check out [this blogpost](https://medium.com/@kentcdodds/what-open-source-project-should-i-contribute-to-7d50ecfe1cb4) for inspiration on how to identify a good project to contribute to.

Identifying How to Contribute to an Open Source Project on GitHub

You cannot push code to repositories that you don’t own or have sufficient permission to. So instead, you make your own copy of the repository by “forking” it. You are then free to make any changes you wish to your repository.

How to Fork and Clone a GitHub Repository

Before you start making your changes, you often need to set up your environment for the changes. This is where the repositories' contributing instructions come in really handy. In this lesson we’ll get our environment set up and ready for changes.

Setting up the project locally

Often when making a change, you want to verify your approach with the maintainer or ask them for help. In this lesson we’ll make a change and commit that WIP change. Then we’ll create a pull request requesting help from the project maintainer.
