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 database – all CRUD operations

We will, of course, need a datastore for our create, read, update, and delete functionality, so let's return to MongoDB in order to store these documents. You can refer back to Chapter 18, Node.js and MongoDB, if you need to refresh your memory on getting set up.

To get started with setting up a database from scratch, it helps to think of the database structure that you intend to use. While MongoDB doesn't require a schema, it's still a good idea to plan your MongoDB documents so that you're not being arbitrary with functionality or naming between sections.

Here's an idea of what each collection might look like:

settings:  {
user
firstname
lastname
username
password
title
URL
media directory
}

entry: {
title
location
date
month
day
year
body
}

location: {
city
region
country
latitude
longitude
entries
}

It's good to keep your database simple, but remember that you can always expand on...
