"description": "Node.js is an open source, cross-platform runtime environment and library that is used for running web applications outside the client’s browser.\n\nIt is used for server-side programming, and primarily deployed for non-blocking, event-driven servers, such as traditional web sites and back-end API services, but was originally designed with real-time, push-based architectures in mind. Every browser has its own version of a JS engine, and node.js is built on Google Chrome’s V8 JavaScript engine.\n\nVisit the following resources to learn more:",

"title": "What is Node.js?",
"description": "Node.js is an open-source and cross-platform JavaScript runtime environment. It is a popular tool for almost any kind of project! Node.js runs the V8 JavaScript engine, Google Chrome's core, outside the browser. This allows Node.js to be very performant. A Node.js app runs in a single process, without creating a new thread for every request. Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm.\n\nVisit the following resources to learn more:",

"description": "Node.js is a cross-platform runtime, perfect for a wide range of use cases. Its huge community makes it easy to get started. It uses the V8 engine to compile JavaScript and runs at lightning-fast speeds. Node.js applications are very scalable and maintainable. Cross-platform support allows the creation of all kinds of applications - desktop apps, software as a service, and even mobile applications. Node.js is perfect for data-intensive and real-time applications since it uses an event-driven, non-blocking I/O model, making it lightweight and efficient. With such a huge community, a vast collection of Node.js packages is available to simplify and boost development.\n\nVisit the following resources to learn more:",

"title": "Global Installation",
"description": "NodeJS and NPM allow two methods of installing dependencies/packages: Local and Global. This is mainly used when adding a package or dependency as part of a specific project you're working on. The package would be installed (with its dependencies) in `node_modules` folder **under your project**. In addition, in `package.json` file there will be a new line added for the installed dependency under the label `dependencies`. At this point - you can start using the package in your NodeJS code by importing the package. Unlike the local install, you can install packages and dependencies **globally**. This would install it in a system path, and these packages would be available to any program which runs on **this specific** computer. This method is often used for installing command line tools (for example, even `npm` program is a Globally installed npm package).\n\nVisit the following resources to learn more:",

"title": "Async Programming",
"description": "Asynchronous code means that things can happen independently of the main program flow, async functions in JavaScript are processed in the background without blocking other requests. It ensures non-blocking code execution. Asynchronous code executes without having any dependency and no order. This improves the system efficiency and throughput. Making web apps requires knowledge of asynchronous concepts since we will be dealing with actions that require some time to get processed.\n\nVisit the following resources to learn more:",

"title": "Promises",
"description": "A promise is commonly defined as a proxy for a value that will eventually become available. Asynchronous functions use promise behind the scenes, so understanding how promises work is fundamental to understanding how \"async\" and \"await\" works. Once a promise has been called, it will start in a pending state. This means that the calling function continues executing, while the promise is pending until it resolves, giving the calling function whatever data was being requested.\n\nCreating a Promise: The Promise API exposes a Promise constructor, which you initialize using new Promise().\n\nUsing resolve() and reject(), we can communicate back to the caller what the resulting Promise state was, and what to do with it.\n\nVisit the following resources to learn more:",

There are four types of streams in Node.js.\n\n* **Readable**: streams from which data can be read.\n* **Writable**: streams to which we can write data.\n* **Duplex**: streams that are both Readable and Writable.\n* **Transform**: streams that can modify or transform the data as it is written and read.\n\nMultiple streams can be chained together using `pipe()` method.\n\nVisit the following resources to learn more:",

"title": "Debugging",
"description": "Debugging is a concept to identify and remove errors from software applications. Here, we will learn about the technique to debug a Node.js application.\n\nWhy not to use console.log() for debugging?\n-------------------------------------------\n\nUsing `console.log` to debug the code generally dives into an infinite loop of “stopping the app and adding a console.log, and start the app again” operations. Besides slowing down the development of the app, it also makes the writing dirty and creates unnecessary code. Finally, trying to log out variables alongside with the noise of other potential logging operations, may make the process of debugging difficult when attempting to find the values you are debugging.\n\nVisit the following resources to learn more:",

"description": "Memory leaks are caused when your Node.js app’s CPU and memory usage increases over time for no apparent reason. In simple terms, a Node.js memory leak is an orphan block of memory on the Heap that is no longer used by your app because it has not been released by the garbage collector. It’s a useless block of memory. These blocks can grow over time and lead to your app crashing because it runs out of memory.\n\nVisit the following resources to learn more:",

"title": "Using APM",
"description": "As much fun as it is to intercept your container requests with inspect and step through your code, you won’t have this option in production. This is why it makes a lot of sense to try and debug your application locally in the same way as you would in production.\n\nIn production, one of your tools would be to login to your remote server to view the console logs, just as you would on local. But this can be a tedious approach. Luckily, there are tools out there that perform what is called log aggregation, such as Stackify.\n\nThese tools send your logs from your running application into a single location. They often come with high-powered search and query utilities so that you can easily parse your logs and visualize them.\n\nVisit the following resources to learn more:",
