GitHub is the one-stop-shop for everything related to (web) development these days. Frameworks, demos, collections of all sorts — there’s probably nothing you cannot find on GitHub. However, this huge quantity of things is the problem. There are cool things you’ll probably never hear about, simply because there are so many repositories available.

So, once again I’ve decided to bring to you some of the most popular GitHub repositories you should know about, each of them having at least ~30,000 stars.

Realworld

The first repository in this list is Realworld. Its creators call it nothing less than “The Mother of all Demo Apps.” A bold statement, for sure, but I don’t think it’s an exaggeration.

Realworld is an exemplary Medium.com clone. But not only that. The repository lets you choose between different front end and back end implementations, which you can happily mix.
Vue.js + Node/Express or React /Redux + Rust? They got it!

Realworld shows you how the exact same blog app is built on almost any popular language or framework. How awesome is that?

You Don’t Know JS Yet

This repository is a popular book series by Kyle Simpson who is widely known under his alias, Getify. The books dive deep into the mechanics of JavaScript and cover the following topics:

• Get Started
• Scope & Closures
• Objects & Classes
• Types & Grammar
• Sync & Async
• ES.Next & Beyond

The best thing? It’s completely free to read! It’s definitely one of the best series about JavaScript and it really helped me to understand what JS is really about. Even if you think you know JavaScript well — read the books! You will be surprised, I promise.

Airbnb JavaScript Style Guide

A mostly reasonable approach to JavaScript.

The Airbnb JavaScript Style Guide is one of the most popular and commonly used style guides out there. It helps you write better JS code and is especially helpful in teams and in combination with ESLint.

Here is an example from the docs regarding the use of const instead of var:

Storybook

Storybook is a development environment for UI components. It allows you to browse a component library, view the different states of each component, and interactively develop and test components. It supports React, Vue, Angular, React Native, Ember, Web Components, and more!

Storybook runs outside your app. This allows you to develop UI components in isolation, which can improve component reuse, testability, and development speed. You can build quickly without having to worry about application-specific dependencies.
You can find some great examples here.

It looks really cool so check it out!

I hope you can use some of these repositories for your projects or other purposes.
