You will also learn how to send requests to a server and have a response relayed to the client. The REPL (Read-Eval-Print Loop) terminal is discussed in detail. You will learn how to perform mathematical expressions and declaration of variables on the terminal. The execution of multiline expressions on the REPL terminal is explored. You might need to scale your Node.js application. This book will guide you through doing this. Streams, the RESTful API, and events in Node.js are discussed. Sometimes, the files for your Node.js project might be located separately in a particular directory. This book will guide you on how to package these files together.
