Hands-on JavaScript for Python Developers

By: Sonyl Nagale

Overview of this book

Knowledge of Python is a great foundation for learning other languages. This book will help you advance in your software engineering career by leveraging your Python programming skills to learn JavaScript and apply its unique features not only for frontend web development but also for streamlining work on the backend. Starting with the basics of JavaScript, you’ll cover its syntax, its use in the browser, and its frameworks and libraries. From working with user interactions and ingesting data from APIs through to creating APIs with Node.js, this book will help you get up and running with JavaScript using hands-on exercises, code snippets, and detailed descriptions of JavaScript implementation and benefits. To understand the use of JavaScript in the backend, you’ll explore Node.js and discover how it communicates with databases. As you advance, you’ll get to grips with creating your own RESTful APIs and connecting the frontend and backend for holistic full-stack development knowledge. By the end of this Python JavaScript book, you’ll have the knowledge you need to write full-fledged web applications from start to finish. You’ll have also gained hands-on experience of working through several projects, which will help you advance in your career as a JavaScript developer.

Making a restaurant database with Yelp and Firebase

Our applications up to this point have been fairly simple, storing information on the filesystem. However, in most cases you'll want it to be some sort of database instead of static files. We're going to be using Firebase, a cloud-based NoSQL database that plays well with JavaScript, but first, let's set up our React scaffold.

The starting line - creating a React app

We've gone through this setup a few times before, so it should be no surprise:

  1. Create a new React application with npx create-react-app restaurant-finder and we're ready to go!
  2. Test your setup with npm start and access http://localhost:3000.

Getting set up with Firebase

The first thing we want to do is set up our Firebase account.

Please keep in mind that the user interface for Firebase (as with most websites) does change periodically, so I won't be showing you screenshots for the signup process. If you run into any problems with the setup...
