Learn Bash, Next and Svelte

### Accept payments & sell products powered by Stripe and the best of the JAMStack

There are as many ways to build an e-commerce store on the internet as there are products to sell. One thing is for certain, e-commerce is here to stay and as professional developers we need to understand how to build fully custom stores for our clients using the best modern tools available.

- React: flexible and customizable while following modern best practices
- Next.js: lightening fast with guide rails to help your project perform as consumers expect
- Stripe Checkout: lets you offload reams of complicated business logic to a trusted third party that maintains regulatory compliance, global payments, and a standard UX.

Your store will have well managed local component state using React Hooks and you'll also have clear and cohesive shared (global) state with React Context.

Finally you'll deploy your custom store to Vercel (the platform behind Next.js) as well as how to make your Next.js e-commerce store portable to deploy to other platforms.

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.

Databases are essential for any full-stack applications, but working with them is traditionally very difficult. Prisma is here to change that. It's a powerful database toolkit that helps us think in data itself - not SQL, not classes, just the data we care about in our apps.

In this series, we will learn how to leverage the power of Prisma to automatically generate a type-safe, autocomplete-ready, and efficient query builder, all based on a simple and easy-to-read schema. We will integrate all this good stuff into a Next.js project to complete a simple social network app.

In the end, you will be able to understand how Prisma works, and confidently start using Prisma in your own project.

Prisma is an open-source database toolkit. It replaces traditional ORMs and makes database access easy with an auto-generated query builder for TypeScript & Node.js.

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.

Upgrade Your Terminal and Make It a Joy to Work with

Extracting meaningful data from strings is a crucial skill when working with bash, and bash gives us powerful tools to do so: `head`, `tail`, `cut`, `sed`, and `awk`. But these tools can be hard to understand without spending time to learn them, so many developers fall into a rut of blindly copying and pasting commands. No more! With this mini-course, you'll understand the basic ins and outs of these commands in under 15 minutes. 


Manipulating strings in bash

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.

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.

Secure GitHub connections with SSH

“Setting up remote server authentication” will never be on your job description. It’s not one of those desirable responsibilities that convinces talented people to move across the country and pursue the job of their dreams.

But at that dream job, you might be asked to set up an SSH key. You’d better be ready.

In this course, we will learn the fundamentals of creating SSH keys and configuring them for connectivity to a remote server. We’ll figure out how to:

- tunnel SSH connections for easier local debugging
- set up configuration files to simplify the aspect of connecting to remote servers
- use security features like blocking incoming connections

Being prepared is key. Learn the skills now!

SSH for Remote Server Authentication

With the release of `Next.js` v9+, we've been handed the tools to create full-stack react apps with ease. 

This collection will dive into the fundamentals of API & Dynamic routing, handling data from local json and a DB, plus deployment options. 

This collection will be an ongoing collection, where I continue adding more videos over time 😃

Bash makes automation easy. Just a few lines of code can take care of repetitive tasks for you and your teammates. 

In this course, we’ll dive deep into the automation potential of bash. You’ll learn to leverage common hooks that open up interesting automation possibilities, like git hooks, adding functions and aliases in your bash_profile, and running scheduled jobs in launchd.

For example, we’ll write a git hook that checks package.json for changes, and if there are changes, the hook runs npm install for you automatically. 

Along the way, you’ll also learn:

- more advanced bash commands like exec
- syntax such as redirecting stdout and stderr to the same destination
- timesaving tricks like brace expansions

Automation is all about saving you time — and at only 52 minutes, this course is well worth yours. Enjoy!

Advanced Bash Automation for Web Developers



Humans were never meant to repeat joyless tasks in a precise manner, over and over and over. Computers are meant precisely for these types of tasks.

Bash is a ubiquitous technology in web development that gives you the immense power of automating repetitive tasks you find yourself performing throughout the day.

The topics we cover will give you confidence in creating build scripts that run on continuous integration servers or quickly testing and debugging an API with `curl`. We’ll go over:  - Interacting with the file system - Creating, moving, copying, and deleting files and folders - Finding files and text patterns in files - Creating and running scripts - Language syntax like variables and conditionals.

Automate Daily Development Tasks with Bash

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.

Lots of if and if else statements are hard to read and tough to maintain in any language, and bash is no exception. In this lesson, we’ll learn how to use `case`, bash’s construct for a switch statement. In bash, `case` actually does pattern matching, which gives some great flexibility. We’ll write a script that will uncompress a variety of different archive file  types (like .tar or .zip), based on their file extension. 

Use case for Complicated Conditional Statements in Bash

Let’s say you want to allow a user to pass a `-v` flag to turn on verbose logging in a script. Manually parsing out options passed to a script is difficult, but in this lesson, we’ll learn about `getopts` which makes it easy. We'll look at the limitations of using getopts (options must be in a format like `-a` or `-ab <value>`) as well as the importance of shifting processed options off of the argument array. 

Create a Bash Script that Accepts Named Options with getopts

In this lesson, we’ll apply our knowledge of `getopts` and create a script that opens a PR on Github, all without leaving your terminal. We’ll use `getopts` to take 3 options: username, password or token, and PR title. We’ll use any input after that as the body of the PR. We’ll validate the input and then use `curl` to POST it to Github.

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.

Bash is great, but sometimes we need the power of a more robust programming language to accomplish our goals. In this lesson, we’ll look at how we can integrate node.js within bash to send data to and from a node.js script. First we’ll look at how to do quick one-liners at the shell using node's `-p` (print) option. Then we'll write a node.js script that accepts parameters from the shell to check the value of a query string. In node.js, we can use the `process` object to interact with command line arguments and stdio. 

Send and Receive Data from a Node.js Script in Bash using the Process Object

Pipes are one of bash's most powerful features, but sometimes plain bash doesn't give us the tools we need to perform more complicated transformations. In this lesson, we'll see how we can leverage node.js in conjunction with bash. We'll pipe a log file of line-delimited JSON (LDJSON) to a node script that filters it and then writes the result to stdout. We'll use node.js' Transform stream to accomplish this. 

Transform Piped Data from Bash using a Node.js Transform Stream

A Unix command used to search files for the occurrence of a string of characters that matches a specified pattern.

grep

When you have a bunch of text to sift through, standard Unix command line utilities like `grep`, `sed`, `awk`, `cut`, `sort`, and `uniq` can help extract the information you want. For example, with a git log for a project, you might want to group commits by day in order to see which days you're most productive, or find out how many commits you made last year. In this lesson, you'll learn how to combine these commands with the pipe operator to extract this data from git logs.
