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.

The backend – setting up our API

Let's catalog the endpoints we'll need to make our travelogue work:

  • Read (GET): Like most APIs, we'll need an endpoint to read entries. We won't force authentication or being logged in for this.
  • Write (POST): This endpoint will be used for both creating a new trip and editing existing ones.
  • Upload (POST): We'll need an endpoint to call from our frontend in order to upload photos.
  • Login (POST) (Optional): If you'd like to take your authentication into your own hands, create a login endpoint that can use credentials from the database or a social-media login endpoint.

  • Media (GET) (Optional): It will be useful to have an API that lists all of the media files uploaded to your server.
  • Countries (GET) (Optional): It will also be a good idea to have an endpoint specifically for listing the countries you've visited to power your world map.

You may find yourself creating more endpoints as you work, and that's...
