Middleware

One of the most distinctive patterns in Node.js is definitely Middleware. Unfortunately, it's also one of the most confusing for the inexperienced, especially for developers coming from the enterprise programming world. The reason for the disorientation is probably connected to the traditional meaning of the term middleware, which in enterprise architecture jargon represents the various software suites that help to abstract lower-level mechanisms such as OS APIs, network communications, memory management, and so on, allowing the developer to focus only on the business case of the application. In this context, the term middleware recalls topics such as CORBA, enterprise service bus, Spring, JBoss, and WebSphere, but in its more generic meaning, it can also define any kind of software layer that acts as glue between lower-level services and the application (literally, the software in the middle).

Luciano Mammino

Luciano Mammino is a software engineer born in 1987, the same year that the Nintendo released Super Mario Bros in Europe, which by chance is his favorite video-game. He started coding at the age of 12 using his father's old Intel 386, provided only with the DOS operating system and the qBasic interpreter. After a master's degree in computer science he developed his programming skills mostly as a web developer working mainly as freelancer for companies and startups all around Italy. After a start-up parenthesis of 3 years as CTO and co-founder of Sbaam.com in Italy and in Ireland, he decided to relocate in Dublin to work as senior PHP engineer at Smartbox. He loves developing open source libraries and working with frameworks such as Symfony and Express. He is convinced that the JavaScript fame is still at the very beginning and that this technology will have a huge impact in the future of most of the web-and mobile-related technologies. For this reason, he spends most of his free time improving his knowledge of JavaScript and playing with Node.js.

Today's web demands efficient real-time applications and scalability. Asynchronous event-driven programming is ideal for this, and this is where Node.js comes in. Server-side JavaScript has been here since the 90s, but Node got it right. With Node for tooling and server-side logic, and a browser-based client-side UI, everything is JavaScript. This leads to rapid, fluid development cycles. The full-stack, single language experience means less context-switching between languages for developers, architects and whole teams.
