Node.js is well-known for its unique architecture and ability to manage concurrent requests effortlessly. So, if you want to build a fast, efficient, and scalable server-side application, choose Node.js. Even if you are an entrepreneur with no technical know-how, understand that drawing a project structure for your development project is essential. Node.js, the widely chosen back-end technology, can handle hundreds of thousands of requests.
Companies like Netflix, Trello, Uber, and Twitter hired Node.js web app development services to create such stunning apps. They have observed a sharp decline in startup loading time and improvement in front-end to back-end transition. The blog talks about Node.js architecture, which starts on the client side and ends on the server. Also, we will discuss some of the best practices you can implement during the Node.js web development process.
Why Do You Need a Project Architecture?
As previously stated, selecting the appropriate project architecture will improve your starting point, and you will already win half the battle. Eventually, you can adapt to future needs, which is what you want as a developer. The incorrect project architecture frequently results in the following:
- Difficult-to-read and comprehending code slows development and makes testing the finished product more challenging.
- Code management and maintenance become more complex when duplication occurs needlessly.
- It's challenging to add new features without breaking old code.
Node.js’s simple architecture is helpful in this situation. By applying Node.js architecture best practices, you can:
- Write code that is clear and readable.
- Stay away from repetition.
- Add additional functionality without altering the current code.
- Include reusable code across the program.
What is Node.js Architecture
Node.js architecture is unique, and developers use Node.js frameworks to create stunning web apps. The “Single-Threaded Event Loop” architecture provided by Node.js allows for managing concurrent requests without creating additional threads and using fewer threads to conserve resources. Because of this, developers favor the Node.js architecture to benefit from its features.
Node.js’s callback system and JavaScript-event-based model contribute to its popularity.
Single-Threaded Event Loop
Despite using a single thread, Node.js’s architecture is built to manage thousands of concurrent requests effectively.
Non-Blocking I/O Operations
Node.js improves application performance by ensuring that I/O operations do not impede the execution of other code through asynchronous programming.
Event-Driven Architecture
Node.js can listen for and respond to events asynchronously thanks to the event-driven approach, which guarantees effective resource use.
Scalability
The design is appropriate for managing large-scale applications since it allows vertical and horizontal scaling.
Cross-Platform Compatibility
Node.js gives developers flexibility by running on various operating systems, such as Windows, macOS, and Linux.
Main Components of Node.js Server Architecture
Most of the time, technologies that have server-side, such as ASP.NET, PHP, Java, and Ruby, use multi-threaded models. During each client request, classic architectures create threads. Using its Single Threaded Event Loop Model Architecture, Node.js avoids generating numerous threads for every request. Consequently, a single thread is used to process all client requests.
Event Loop
Asynchronous actions in Node.js are centered upon the event loop. It continuously checks for jobs, performing them sequentially while handling I/O activities in the background. This is how it operates:
Timers Phase
Makes callbacks that are scheduled by setTimeout() and setInterval()
Pending Callbacks Phase
It can handle I/O callbacks that the OS defers.
Idle, Prepare Phase
Handles internal operations for Node.js
Poll Phase
Bring back new I/O events and execute all the relevant callbacks.
Check Phase
It can process setImmediate() callbacks.
Close Callbacks Phase
It can execute cleanup callbacks.
V8 JavaScript Engine
The V8 engine instantly compiles JavaScript code into machine code, guaranteeing fast execution. Applications built using Node.js are quick and effective due to its speed optimization features.
Node.js APIs
A wide range of built-in APIs are available in Node.js for developing server-side features such as file system operations, buffer management, and HTTP requests.
Modules
Because Node.js is modular, developers can use the require() function to incorporate third-party and built-in modules. The Node Package Manager (NPM) stores thousands of reusable modules.
Libuv
A package called Libuv offers an abstraction layer for asynchronous input/output processes. It supports file system access, networking, and timers and makes the event loop possible.
Top Benefits of Node.js Architecture
When you hire Node.js app developers to create efficient and scalable web apps, you will get the following benefits:
Good Performance
The main advantages of using the event-driven programming of the Node.js architecture over other technologies include faster speed and better performance. It assists you in creating a basic program by coordinating the occurrence of several events.
Flexibility
You don’t have to worry about the complete development process when you are about to make changes to the Node.js application’s code. Because the updated code only affects a particular Node. Therefore, for both the initial build step and continuing application maintenance, Node.js is the best option for web application development.
Security
The most crucial aspect of any software program is safety and security. You cannot jeopardize the security and safety of the application you created. In this regard, Node.js complies with security standards protocols such as HTTPS, SSL/TSL, web crypto API, and others.
Vibrant Ecosystem
Node.js has an extensive ecosystem of tools, libraries, and modules to speed development. More than a million packages are available on NPM, so it is considered the best choice even for enterprise app development.
Scalability
The built Node.js application can handle thousands of concurrent client requests without interfering with the system or process. You can benefit from Node.js’s microservices design because of its lightweight nature. Thus, it is understandable why businesses are considering using NodeJS to create microservices.
Language Sharing Throughout the Stack
With JavaScript, Node.js allows developers to use it for both front-end and back-end development. As a result, the language is more uniform throughout the program. Here’s where it differs from other front-end languages like HTML, CSS, and JavaScript, as well as back-end languages like PHP, Java, and Ruby on Rails.
More Use Cases
The versatility of Node.js is impeccable, as it can be used across several domains. Some of the top use cases that can be considered are as follows:
- Can create high-performing and scalable web servers and full-stack applications.
- Can build robust RESTful APIs and GraphQL endpoints for easy app communication.
- Can create real-time applications such as chat apps, live notifications, editing tools, and online gaming.
- It can break down large applications into more minor, independent services, making it easy to develop and deploy
- It is used to power audio and video streaming platforms and handle data streams.
- It is used to manage data flow and communication in IoT networks.
Best Practices That You Must Follow in Node.js Application Architecture
As a top Node.js development company in India and the USA, we have implemented the following best practices for all our web application development projects. You can create a solid and perfect Node.js application structure with all of these:
Practice a Layered Approach
Using Express.js, a well-liked Node.js framework, you can follow the “separation of concerns” approach while developing. This codebase division technique makes it simple to separate the business logic from Node.js API routes and segregate the codebase into three categories: business logic, database, and API routes.
You can use the below layers:
- The controller layer obtains information about API routes and deconstructs request objects using route handler functions.
- Service Layer to define business logic related to the application.
- Data Access Layer to handle the database from writing, reading, or database updates.
Use Dependency Injection
One software design pattern is dependency injection, which involves passing one or more services (dependencies) into a dependent object by reference. With dependency injection in Node.js application, you get the below advantages:
- Giving the modules you wish to use dependencies instead of hardcoding them will make unit testing easier.
- To simplify maintenance significantly, do not connect unnecessary parts.
- Make your git flow faster. Once you specify your interfaces, they will stay defined, avoiding merge conflicts.
Use Third-Party Solutions
The support of a sizable developer community is why the Node.js platform is popular. As previously stated, NPM, or Node Package Manager, is included with Node.js and has a wealth of feature-rich, thoroughly documented frameworks, libraries, and tools. Additionally, it makes it simple to install all third-party modules in Node.js frameworks.
Use a Linter
The linter tool will improve performance and the entire development process. It will also assist you in identifying minor mistakes while preserving the application’s code consistency.
Use a Style Guide
Do you still want to format your Node.js application code? Why not take advantage of the fantastic style recommendations Google or Airbnb offers? After implementing the coding style guide, I’m confident you won’t become upset when attempting to read and comprehend the code.
Use Gzip Compression
You can shrink the files using Gzip compression before delivering them to a web browser, eliminating latency and lag.
Conduct Unit Testing
We can incorporate unit testing into our Node.js app. Testing is the most important aspect of developing a Node.js application. It is crucial to the project’s overall success, as defective code obstructs development and causes additional problems. The main objective is to isolate and test a part of the code. In procedural programming, a unit could be a single function or a process.
Use Promises
Callbacks are one of the simplest ways to handle asynchronous programming in JavaScript. Raw callbacks, however, frequently compromise the application control flow, error management, and semantics when synchronous code is used. It can be resolved by using promises in Node.js.
