Node.js is gaining significant interest for building scalable web applications. Several large companies like LinkedIn, eBay, and Walmart are using Node.js in production for its performance and scalability benefits when handling input/output bound workloads. Node.js allows non-blocking event-driven programming which helps simplify building applications that interact with services, databases, and handle many concurrent connections using little memory. Its large ecosystem of open-source modules also helps speed up development.
Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine that uses an event-driven, non-blocking I/O model. It allows creation of web servers and networking tools using JavaScript. The npm package ecosystem is the largest ecosystem of open source libraries in the world and is the default package manager for Node.js. Node.js has asynchronous, non-blocking APIs and uses an event loop model that makes it lightweight and efficient for building scalable web servers and applications.
Node.js is an asynchronous event-driven JavaScript runtime that uses non-blocking I/O to build scalable network applications.

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. It allows JavaScript to be run on the server-side. It is used for building scalable network applications and real-time web applications. Some key things it allows are creating HTTP servers with just a few lines of code, building streaming and real-time services easily, and using a single programming language (JavaScript) for both server-side and client-side code.
Node.js
JavaScript code may be run outside of a web browser Thanks to the open-source, cross-platform runtime environment known as Node.js. Ryan Dahl first presented it in 2009, and it has subsequently gained popularity as a server-side programming language.
In this post, we'll examine Node. Js' fundamentals and how server-side programming might benefit from it. We'll also look at some of Node. Js' essential attributes have helped it become so well-liked by programmers.
Overview of Node.js
A server-side runtime environment called Node.js was constructed on top of Google's V8 JavaScript engine. Developers can now employ JavaScript, which was previously solely used on the client side, to create server-side code. With the help of Node.js, programmers can build highly scalable, event-driven apps that can manage several concurrent connections.
History of Node.js
Developer Ryan Dahl first released Node.js in 2009 with the goal of enabling JavaScript programmers to build highly scalable network applications. He developed Node.js on top of the Google Chrome-compatible V8 JavaScript engine and made it available as an open-source project.
Benefits of Node.js
The use of Node.js for server-side development has a number of advantages. A few of these are:
Performance: The V8 JavaScript engine, which is highly optimized for performance, is the foundation upon which Node.js is constructed. Because of this, Node.js apps can handle numerous connections at once without experiencing performance issues.
Scalability: Node.js applications have a great degree of scalability and can manage numerous concurrent connections without the installation of additional hardware.
Easy to Learn:Node.js is reasonably simple to learn because it leverages JavaScript, a well-known language among developers.
Large Community: Node.js has a sizable developer community that supports one another and contributes to the open-source project.
Introduction to Node.js
Setting up Node.js
You must install Node.js on your computer before you can begin using it. Node.js can be downloaded from the official Node.js website, which also provides installation guidance.
figuring out npm
Developers may quickly install and manage dependencies for their Node.js apps using npm (Node Package Manager), a Node.js package manager. There is no need to install npm individually because it is part of Node.js.
Basics of Node.js
Knowledge of the Event Loop
On top of an event-driven, non-blocking I/O mechanism, Node.js is constructed. This indicates that Node.js processes numerous jobs concurrently by using an event loop rather than waiting for I/O operations to finish before going on to the next task. Because of this, Node.js apps can handle numerous connections at once without experiencing performance issues.
(This is the version of the session given at ICON UK, 13/9/18).

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
UI5con 2024 - Bring Your Own Design SystemPeter Muessig
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.
A Study of Variable-Role-based Feature Enrichment in Neural Models of CodeAftab Hussain
Understanding variable roles in code has been found to be helpful by students
in learning programming -- could variable roles help deep neural models in
performing coding tasks? We do an exploratory study.
- These are slides of the talk given at InteNSE'23: The 1st International Workshop on Interpretability and Robustness in Neural Software Engineering, co-located with the 45th International Conference on Software Engineering, ICSE 2023, Melbourne Australia
