By simplifying the testing process and providing the ability to replace more challenging aspects of tests, Sinon.JS enables you to create robust, efficient applications with confidence. PM2 is a Node.js-based framework and production process manager, https://www.globalcloudteam.com/ featuring a built-in load balancer for Node.js applications. It allows you to run applications in cluster mode, spawning processes for multiple CPU cores simultaneously, and update applications with zero downtime through the “hot reload” option.
Debug your Express app
- It happens smoother when the application model is based on Node.js’s event-driven model rather than a classic MVC.
- Whether you’re working on a small project or a large-scale application, Sinon.JS is an invaluable tool for ensuring the quality and reliability of your code.
- As we know, these days along with data structure and algorithms , our development skill is also very important to crack the tech giants .
- With the same language on both sides, you can reuse code on the frontend and the backend by wrapping it into modules and creating new levels of abstraction.
- As of version 19.5, Node.js uses the simdutf library for fast Unicode validation and transcoding.

⊕ Robust technology stack
The main thread function call posts tasks to the shared task queue, which threads in the thread pool pull and execute. When a thread in the thread pool completes a task, it informs the main thread of this, which in turn, wakes up and executes the registered callback. As a developer, staying abreast of the latest best practices, trends, and technologies in the continuously evolving world of Node.js development is vital. To help you stay ahead of the curve, we’ve compiled a list of learning resources and tutorials that will provide you with the knowledge and skills necessary to become a proficient Node.js developer. With a strong GraphQL API and a user-friendly interface, Keystone.js is an excellent choice for developing web applications and APIs that are both functional and secure. Koa.js is suitable for constructing various types of applications, including blogs, content management systems, and ecommerce platforms.
Event loop collects new callbacks and polls for new incoming requests from the event queue when other operations are finished. Whether you’re developing a real-time application, IoT device, or high-traffic site, Node.js can give you speed, efficiency, and lower development costs. There are thousands of open-source libraries for Node.js, most of them hosted on the npm website. There are multiple developer conferences and events that support the Node.js community, including NodeConf, Node Interactive, and Node Summit as well as a number of regional events. With comprehensive documentation and a wealth of examples available on the official Koa.js website, developers can quickly learn how to build JS apps and APIs using this powerful framework. All of these extensions are available at the official Visual Studio Code Marketplace.
A debugging tool not only helps you gain a better understanding of your code but also enables you to pinpoint areas for improvement and optimization. These are often similar to, or the same as, those offered by nvm-windows. You should use the Current release if you need a feature that is not present in the LTS version.
From there you can inspect variables, create watches, and step through your code. You’ll need to open a new terminal (command prompt) for the node and npm command-line tools to be on your PATH. Obviously, with all the listed Node.js advantages and disadvantages, the technology is no silver bullet. Yet, there are specific cases where each one of the listed technologies perform best.
