Chapter 1 covers the concepts related to the client-side and server-side. You will learn the difference between the client and server and how the interactions happen between client and server. In the later part of this chapter, we would be also learning the client and server-side concepts in which a database like MongoDB is also involved. We would be exploring how the dynamic sites which are using databases like MongoDB work, how the server processes these requests and sends them back to the client. In the last section of this chapter we would be covering the MongoDB drivers and why they are used, what are the programming languages that are currently supported by MongoDB, and the MongoDB community availability of drivers. Chapter 2 covers the data entry part using MongoDB Compass after creating the database and collection using MongoDB Compass so that we can have some real data to work with our next chapters. Chapter 3 covers the introduction to PHP programming with MongoDB and how we can use PHP with MongoDB. In order to run PHP with MongoDB server, we should be having the right environment in place. So this chapter covers how we can set up the right environment to run PHP codes. In this chapter, we will learn what WAMP server is and how to install WAMP server. Later in this chapter, we will cover how we can set up MongoDB with PHP and WAMP server. In the last section of this book, we would be doing some coding and running some practical examples to connect and work with MongoDB server using PHP. Chapter 4 covers the introduction to JavaScript programming language. We will learn Node.js programming with MongoDB and how we can use Node.js with MongoDB. In order to run Node.js with MongoDB server, we should be having the right environment in place. So this chapter covers how we can set up the right environment to run Node.js codes. In this chapter, we will learn what Node.js is and how to install Node.js. Later in this chapter, we will cover how we can set up MongoDB with Node.js.
