<h2>Introduction to the course</h2><p>Node.js Advanced is a course we&#x27;ve created to introduce the more complex side of development.</p><h2>Who is this course for?</h2><p>If you&#x27;re a developer with the basic and fundamental concepts of Node.js down, then this course is meant for you to discover the uncharted lands of Node.js.</p><h2>Recommendations for the course:</h2><p>Make sure you&#x27;ve completed our Node.js course to ensure the strong foundation you&#x27;ll be needing here.</p>

Node.js Advanced

<h2>What does this lesson cover?</h2><p>The fixed area of the memory we call the Buffer class will be the topic of this lesson.</p><p>Accessing the Buffer class is accessible without importing as it is a part of the Buffer Module, a core Node.js Module.</p><p>The question we&#x27;ll answer is why exactly developers need to incorporate Buffers in code. Thus, we&#x27;ll create Buffers, write to Buffers, copy and decode Buffers, slice Buffers, and define Buffer Bytes.</p>

Buffers

<h2>What does this lesson cover?</h2><p>We&#x27;ve referred to the fs module multiple times in the past lessons, however, the short description we&#x27;ve provided does not suffice and simply does not align with the importance of the fs module.</p><p>This introduction scratches the service of the module that stores all the file query, manipulation functions and gives developers access to working with their computer’s file system. </p>

Introduction

<h2>What does this lesson cover?</h2><p>The Understanding Streams lesson defines the usage and purpose of Streams and differentiates between the two types of Streams– Readable Streams and Writable Streams, Transform Streams, and Duplex Streams.</p><p>We&#x27;ll also be expanding on the widely used mechanisms of Piping Streams and Chaining Streams by identifying where and how to use them in your Node.js application.</p>

Understanding Streams

<h2>What does this lesson cover?</h2><p>This lesson covers a standard method of the fs module that has wide usage in Node.js applications by opening a file and thus allowing the reading and manipulating processes. </p><p>We&#x27;ll also be identifying the elated concept of flags with corresponding examples that depict their usage.</p>

Open a File

<h2>What does this lesson cover?</h2><p>File uploads take place when a user sends a request from a client machine to the server. This process is supported in Node.js with the help of the third-party Formidable Module.</p><p>The said module permits various file uploads that we will be referring o in this lesson. With the help of the methods described in the lesson, developers will be able to upload forms, parse URLs, and save files.</p>

Upload Files

<h2>What does this lesson cover?</h2><p>Information concerning the size of a file for example, or file permissions, and other characteristics that describe files are common info that developers might need to get their hands on at some point in time.</p><p>This lesson covers the steps developers need to take to get that information with the help of methods you can find in the fs module.</p>

Get File Information

<h2>What does this lesson cover?</h2><p>Sometimes, inputting a URL and a callback function is all you need to make a request. That said, the best approach may not always align with simple steps.</p><p>The Request module covers advanced cases when making a request in Node.js.</p><p>After learning how to install the Request Module we&#x27;ll use it in our Node.js application to create servers, follow redirects, etc.</p><p>Each action is depicted in separate lessons with supporting examples and quizzes.</p>

Request Module

Lesson Challenge

<h2>What does this lesson cover?</h2><p>There are a lot of ways for file reading, closing a file and file writing in Node.js. In this lesson, we&#x27;ll refer to the simplest and most efficient of the bunch in both cases.</p><p>The methods described in the lesson will further develop your skills to work with files in Node.js.</p>

Writing/Reading and Closing a File

<h2>What does this lesson cover?</h2><p>Node.js permits us to code an application for mail exchanges through third-party modules that require installation with the npm (Node Package Manager).</p><p>This lesson will cover the exact syntax and structure of the said third-party module, thus, we&#x27;ll get into the process of incorporating that module into code and sending emails with our Node.js application. </p>

Email

<h2>What does this lesson cover?</h2><p>Manipulating files in Node.js is standard practice, we&#x27;ve already assessed some methods regarding access properties, and now it&#x27;s time to learn how to truncate and delete Node.js files.</p><p>The phrase truncate indicates changing the size of your Node.js files. In this lesson, we&#x27;ll assess the method used to truncate files, their syntax, and structure in code.</p><p>Deleting files requires the use of a separate method that we&#x27;ll be referring to also.</p>

Truncate and Delete a File

<h2>What does this lesson cover?</h2><p>Creating a directory in Node.js requires a sequence of steps which we&#x27;ll be analyzing in the following lesson.</p><p>We&#x27;ll also be expanding on the reading, writing, and removing directories from your Node.js application. Each action requires a separate approach that we&#x27;ll digest in individual lessons with supporting code examples and quizzes.</p>

Directories and methods

<h2>What does this section cover?</h2><p>The incorporation of Buffers and Streams in React applications is a crucial step and this section covers the questions why? and how?</p><p>After defining the buffers and everything developers can do with Buffers, we&#x27;ll introduce Streams, the types of Streams, and the fs module that is a requirement for using Streams.</p>

Streams

<h2>What does this section cover?</h2><p>The Node.js File System stores all the file query, manipulation functions and gives developers access to working with their computer’s file system.</p><p>This section covers the wide range of opportunities that the fs module offers developers to incorporate into their advanced Node.js code.</p><p>We&#x27;ll be referencing different file manipulation methods, directories, access methods, but only after covering the basic operations and techniques.</p>

File System

<h2>What does this section cover?</h2><p>Working with Node.js does not always entail limitations regarding core/built-in modules. </p><p>In some cases, developers are meant to use third-party modules and packages to complete their application or incorporate features into their applications that are not available in the core/built-in Modules.</p><p>This section will focus on uploading files, requests, and emailing with the help of packages.</p>
