To get the most out of this book

You will need Python 3.6 or later installed on your computer, as well as Node.js 16 (or later). You should also have the basic knowledge needed to install packages with pip (Python) and npm or yarn (Node.js).

For the deployment of the projects, you will need to create accounts on MongoDB, Heroku, Vercel, Netlify, and Cloudinary (free). For the deployment on DigitalOcean, the cheapest solution is suggested (at the time of writing, 5 USD per month). I have tried to use the cheapest and, where possible, free tiers of the services so you can try before you find a solution that works well for you.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
