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.

Security and Keys

Security is no simple matter. It's important to keep security in mind when designing your applications from the beginning. For example, if you accidentally committed your keys to your repository, you'd have to do some trickery to either remove that from the repository's history or, more likely, you'd have to revoke those credentials and generate new ones.

We simply can't have our database credentials visible to the world in our frontend JavaScript, but there are ways for the frontend to work with databases. The first step is to implement the proper security and understand where we can put our credentials, both for the frontend and the backend.

The following topics will be covered in this chapter:

  • Authentication versus authorization
  • Using Firebase
  • .gitignore and environment variables for credentials
