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.

Scaffolding – React

Our project is a prime candidate for using React for our frontend, so let's outline our requirements for the frontend: One single React application with reusable components and Hooks and context for state saving. Hooks are a new concept compared to our previous use of React. Added in React 16.8, Hooks are functions that allow you to manipulate the state and context for state management within a functional component.

In addition to our handcrafted React app, we'll incorporate a few additional pre-built libraries to simplify our project and to utilize ready-made tools. D3.js is a powerful graphics and data visualization library that we'll leverage for our map. Quill is a rich text editor that will allow you to write the entries with text formatting, and upload and place photos.

It's up to you to decide whether you'd like to start with npx create-react-app or use the scaffolded code provided in the Step 1 folder in the chapter-19 directory...
