Dealing with asynchronously initialized components

Throughout this book, we have stressed how important asynchronous programming is in JavaScript and Node.js, and we have learned a great deal about different ways and patterns to use asynchronous programming effectively. At this point, you might be wondering: why are there still so many synchronous APIs in Node.js, such as readFileSync() from node:fs?

One of the reasons synchronous APIs exist in the Node.js core modules and many npm packages is that they are convenient for handling initialization tasks. In simple programs, using synchronous APIs during initialization can simplify things significantly, and the typical drawbacks of synchronous code remain contained since they only affect the program once, at startup or when a particular component is initialized.

However, relying on synchronous APIs is not always possible. In some cases, a synchronous version may not be available, especially for components that need to perform...

Luciano Mammino

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.
