Node JS: architecture features
The specificity of request processing is that the processes occur without interconnection. Implemented through a single threaded non-blocking event loop. In practice, this technique has served as a good opportunity for the development of systems where the need to process a huge number of network requests as quickly and efficiently as possible. Can be found in applications of famous world niche leaders:
- payment systems;
- taxi call services;
- largest online hypermarkets.
In addition to the special work of the request processing node, of interest is the fact that for developing applications using Node.JS, it is possible to achieve not only an increase in the speed of data processing (which is already a big plus), but also to reduce the amount of code written. Practical confirmation can be found when examining the huge payment system PayPal. Many customers already know about the capabilities of Node.JS and are actively using them to develop their own application. For these purposes, specialists are involved, such as https://fireart.studio/hire-node-js-developers/, who are able to implement even the most complex tasks and improve the performance of the application.
Sharing is also one of the reasons for the popularity of Node.JS. The NodeJS App Development Company was able to use this opportunity to make development much faster, and specialists could better interact with each other, performing specific stages of work. For example, through Google Docs, a developer can demonstrate the process of completing a task to his colleagues in real time.
Another reason to choose Node.JS might be that it might prove ideal for real-time collaboration, or even editable applications where a user sees another user’s document.In addition, Node.JS has the largest ecosystem of open source libraries. source code, the npm package ecosystem.
Since node processes are not restarted on every request, as is the case with PHP, it is necessary to program very carefully to avoid technical errors in the code. Be careful when overwriting variables or populating arrays. Storage problems can quickly arise with arrays if they are not properly populated. If errors are not being detected correctly in Node.js, problems can occur across the entire node server. If an error occurs in a PHP script, it only affects one request, and the whole system just keeps running, then in Node.js the whole process is affected.
- Node.js relies on asynchrony; processing requests in parallel,
- Node.js provides highly scalable web applications.
This means that compared to PHP and Apache not only handles more requests from the user, but also allows more users to access the website at the same time.
