Since its creation, NodeJS has proven itself as the go-to framework for web-based development. Crafted with scalability and performance in mind, enterprise firms and start-ups overwhelmingly use it to create their products.
This article will talk about Node JS web development, use cases, and why small-scale start-ups and large enterprises prefer this framework.
What is NodeJS?
NodeJS is a free runtime application built on the Chrome V8 JavaScript engine and created using JavaScript and C/C++. It performs server-side functions and brings JavaScript programming into the backend for running applications that run on Linux, Windows, and OS X.
The technology was first presented in 2009 when it was introduced through Ryan Dahl at the annual European JSConf.
It is an open-source project. Joyent Cloud Computing, a cloud-based computing company and hosting services supplier, endorsed NodeJS. The company invested in various other technologies, like the Ruby on Rails framework, and offered hosting solutions to Twitter and LinkedIn. It was also one of the initial businesses to adopt NodeJS to build its mobile app backend. It was then adopted by a range of tech leaders, including Uber, eBay, Walmart, and Netflix, to mention a few.
It was only recently that widespread adoption of server-side JavaScript using NodeJS began. The demand for this technology exploded in 2017 and is still high.
How NodeJS Framework Functions?
NodeJS is an open-source platform that is mostly used as a backend language. It's quite simple to use NodeJS: NodeJS accepts client requests and responses using one thread. NodeJS utilizes threads to manage I/O operations and requests. Threads are a set of instructions that the server needs to follow. Threads can run in parallel on the web server side, allowing it to send information to several clients. NodeJS is a uni-threaded looping language. With just one thread, it can handle multiple requests or tasks without causing blockages for just one.
NodeJS is based on the idea of non-blocking and asynchronous I/O. Let's see how each of them works in NodeJS functions.
1. NodeJS as Non-blocking I/O
NodeJS with non-blocking is a program that can handle multiple requests without blocking the thread running for one request. It is also known as I/O, which is not blocking. External systems, such as databases and files, are dealt with through I/O. NodeJS usually does not work with multiple threads since it's only a single thread that cannot manage the CPU tasks. NodeJS is unsuitable for CPU-intensive tasks like calculation or video processing.
2. Asynchronous Type
Asynchronous refers to the fact that a callback function is being run behind the scenes. A callback function is started when an answer is received from a different server or database. Since NodeJS is built around an event-driven design, callback functions are invoked right after a task has been completed. Instead of processing the request, the single thread forwards it to a second system, which resolves the problem and makes it accessible for subsequent requests.
NodeJS adds Libuv, the open-source library feature that can be used for operations. Libuv comes with two crucial functions, which include thread loops. NodeJS functions can become simple to use and implement through these features.
3. Advantages of NodeJS Development
Why is NodeJS the best choice to develop web applications? This is the top issue when dealing with different backend technologies. But, Node JS has various advantages. This is why large brands like PayPal, Netflix, and Uber have all embraced Node JS website development tools.
4. Cloud-Friendly
Its cloud-friendly nature allows it to be highly versatile across a variety of cloud services, such as AWS, Azure, and Google Cloud. This makes it easier to integrate and deploy, which allows companies to increase their resources in response to demand.
For instance, an online marketplace that uses NodeJS can easily scale the server's capacity during busy shopping times to handle the increased traffic volume without downtime while ensuring the smoothest customer experience.
Furthermore, NodeJS facilitates efficient DevOps pipelines by integrating containerization tools such as Docker and orchestration tools such as Kubernetes. This streamlined approach helps speed up the development cycle, allowing teams to iterate and quickly deploy updates. Firstly, NodeJS enhances performance and scalability, enhances efficiency in cloud environments, and encourages rapid business growth.
5. TypeScript for Reduced Bugs
TypeScript's use in NodeJS projects reduces the chance of bugs and improves code clarity and maintainability. TypeScript provides strong typesetting, meaning that variables such as function parameters and return types are clearly defined. This helps developers know what information is expected throughout the codebase, making it simpler to work together and ensuring uniformity.
When defining, for example, the function that pulls information about users via an external API, TypeScript allows developers to specify the exact format of the data returned through types or interfaces. This means that any deviations in the structure of the data can be detected in the development process rather than causing problems in production.
6. Unified Backend and Frontend Development
NodeJS helps create a seamless development workflow by allowing developers to utilize JavaScript for both backend and frontend tasks. This consistency speeds up development and decreases the amount of learning required for new team members.
For instance, a team creating an e-commerce platform could use NodeJS to manage frontend and server-side interactions to ensure smooth data flow and uniform functions across the entire application. This approach to unified development not only streamlines project management but also improves collaboration between developers who share a common toolkit and language.
Utilizing NodeJS, teams can concentrate more on innovation and spend less time managing multiple technologies, thus improving efficiency and productivity in their work. This synergy demonstrates how NodeJS can be a unified technology in the modern world of web development and can benefit projects of all sizes and complexity.
7. Handling of Multiple Requests
Due to its event-driven structure, NodeJS excels at managing multiple I/O-bound tasks simultaneously. This architecture lets it handle a variety of tasks, such as file I/O, network requests, and database operations, concurrently without interfering with other operations.
In a real-time chat application, NodeJS can manage incoming and outgoing messages from several users simultaneously. When new messages arrive, NodeJS processes each one simultaneously, which means that other users can exchange and receive messages with no delays. This non-blocking behavior ensures that the application's responsiveness, even when it is in high use, improves user experience and provides the least amount of latency.
This is why NodeJS is widely used to create applications such as game platforms, collaborative tools, and finance trading platforms that require instant updates and fast interactions.
8. Scalability
NodeJS is well-known for its capacity to scale and efficiently handle increasing workloads without requiring lengthy code rewrites. Its event-driven design is particularly beneficial in microservices environments, which is considered important for applications that require an incredibly high degree of scale. This ensures that NodeJS is a viable option for companies looking to expand.
For example, consider the possibility of a retail platform that utilizes NodeJS as its backend for e-commerce. When customer traffic increases during the holiday season, NodeJS effortlessly handles concurrent requests, providing swift order processing and instant updates on inventory without system overload. The ability to scale up not only improves the customer experience but also helps businesses grow without compromising performance.
9. High Efficiency
NodeJS applications are well-known for their outstanding performance in resource efficiency and execution speed compared to conventional server-side language. This performance is due to NodeJS's unique structure, leveraging non-blocking I/O operations and the single-threaded event loop. In contrast to traditional server-side applications, which create a separate thread for every request, NodeJS is run with a single thread, managing many concurrent connections. This reduces the burden related to thread management and permits NodeJS to utilize the system resources effectively.
Consider an example of a NodeJS server that handles several API requests simultaneously. Instead of waiting for each request to finish sequentially, NodeJS processes incoming requests asynchronously. This means that while one request is awaiting information from a database or another external resource, NodeJS can continue to take care of other requests, increasing speed and responsiveness without affecting the execution flow.
10. Cost and Time Savings
NodeJS provides a broad set of pre-built frameworks and libraries that dramatically speed up development processes. This ultimately reduces costs and speeds up companies' time to market. This efficiency gives companies a competitive advantage by enabling them to launch products or services rapidly.
For instance, a startup developing real-time messaging software utilizes NodeJS to rapidly integrate WebSocket support by using libraries like Socket.IO. This fast integration not only reduces the time to develop but also reduces labor costs related to long backend code and maintenance.
Businesses can easily speed up development processes by leveraging NodeJS's non-blocking I/O model and single-threaded event loop, which ensures flexibility and efficiency in the fast-paced digital world.
11. Versatility
Because of its remarkable scalability and efficiency, NodeJS has proved invaluable in various industries, including healthcare and fintech. The technology helps businesses improve efficiency and dramatically reduce costs.
In fintech, for instance, NodeJS is utilized to create real-time financial applications that can handle massive amounts of transactions quickly and safely. In healthcare, for instance, it allows the development of telemedicine platforms that allow the seamless exchange of information between health professionals and patients, providing rapid access to medical services regardless of where you are located.
The flexibility of NodeJS lets developers customize solutions to the industry's specific needs, such as high-frequency trading algorithms for finance or real-time monitoring of patient systems for healthcare. This flexibility is what makes NodeJS an ideal option for companies looking for robust custom solutions that can adapt to their changing needs.
12. Rich Ecosystem
Its Node Package Manager (NPM) offers a wide array of tools and libraries that significantly improve the efficiency and flexibility of application development. This wide-ranging ecosystem enables developers to integrate crucial features into their applications quickly.
For instance, when creating an online application, developers can discover libraries for tasks like user authentication and data visualization. They can even integrate with APIs from third parties. This access not only speeds up the development process but also allows developers to concentrate on the business's core logic instead of reinventing the wheel.
