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.

Creating a recipe book with APIs and JSON

Part of the beauty of using a backend is to facilitate communication between your application, the filesystem, and APIs. Previously, all the work we did was constrained to the frontend with no persistence. We'll now make a recipe book application that saves our information in JSON format. Don't worry, we'll get to using databases in Chapter 18, Node.js and MongoDB. For now, we'll use local files. Here's what we're going to build:

To get started, we'll be setting up credentials using a third-party API and then forge onward with the code.

Setting up the application

Clone the starter code at Be sure to execute npm install both in that directory and inside client. We'll also need to do a few setup pieces to access our API. To access the Edamam API, sign up for a free...
