Oct 20, 2010 · Explain “Event-Driven” Web Servers to Your Grandma You’ve heard the term event-driven, event-based, or evented when it comes to web servers. Node.js is based on evented I/O. nginx is an asynchronous event-driven web server. But what does the term mean? Here’s an easy way to think about it.

Mar 16, 2020 · In this article, we’ll discuss some of the problems driving innovation in modern web development. Then we’ll dive into the basics of event-driven architecture (EDA), which tries to address these problems by thinking about back-end architecture in a novel way.

MSDN says that the syntax should be object.event += eventHandler (or object.event += new EventHandler(eventHandler);) so after an event is defined ( event Event SomeEvent; ) all that left is to create a method that can be bound to this event.

Jan 26, 2011 · This is solved in OS by using "I/O event notification facilities/interfaces", e.g epoll, poll, kqueue or select. Take a look at deft, and especially its' io/event loop for a concrete example how the "notification systems" mentioned above are used.

Aug 16, 2023 · In this article, we’ll discuss some of the problems driving innovation in modern web development. Then we’ll dive into the basics of event-driven architecture (EDA), which tries to address these problems by thinking about back-end architecture in a novel way.

When implementing a event-driven design, we need r+1 threads: an event loop and r handlers. Each handler takes a request, performs it, and calls the callback once done. So how does this improve things?

Feb 2, 2024 · Event-driven programming is a paradigm where the execution of a program is determined by events such as user actions or messages. Programs respond to events with predefined actions, allowing for asynchronous and responsive behavior, often seen in GUI applications and distributed systems.

Event-driven programming enables decoupled components to communicate by producing, detecting, consuming, and reacting to events. An event-driven program’s flow is determined by events such as user actions, system changes, sensor outputs, or messages from other programs.

Event-driven programming is non-deterministic in the sense that a specification for an event-driven language generally doesn't specify the order that event handlers will be executed in.

Mar 21, 2025 · In this article, we’ll discuss some of the problems driving innovation in modern web development. Then we’ll dive into the basics of event-driven architecture (EDA), which tries to address these problems by thinking about back-end architecture in a novel way.
