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.

Bringing it all together

We'll be working with a complete Shakespeare bot with a frontend and backend. Go ahead and navigate to the shakespearebot-complete directory. In the following steps, we'll set up our application, import our data, and interact with the frontend:

  1. First, run the Django migrations with python manage.py migrate and create a user with python manage.py createsuperuser.
  2. Start the server with python manage.py runserver.
  3. Log in at http://localhost:8000/admin.
  4. Navigate to http://localhost:8000/admin/bot/text/ and import the Shakespeare_text.csv file (this will take some time).
  5. While this is importing, we can go ahead and check our frontend with the cd react-frontend command.
  6. Install our dependencies with yarn install.
  7. Start the server with yarn start.
  8. Now, if you navigate to http://localhost:3000, we should see our frontend:

  1. Stop the development server with Ctrl + C.
  2. Execute yarn build.
  3. When the import is complete,...
