As a developer, nothing brings me more pleasure than reading (and writing) cleanly structured and organized code. This can lead us to the next important development practice to keep in mind – clean code and easy readability. Now that we have a clear understanding of the mechanics of how Node.js works under the hood, let’s segue into the more applied side of things and look at what constitutes an intelligent Node.js project. Now let’s understand each part of the Node.js architecture and the workflow of a web server developed using Node.js. It’s possible to avoid choosing between these two by developing an application in Java and linking to it with JavaScript through an engine like Rhinorun. However, in a real-world scenario, using Node.js for your web application makes more sense.
Event-driven programming is designed to detect actions as they occur, and processes them using establishing event-handling procedures. This provides for a more reactive and intuitive user experience and adds flexibility to applications handling concurrent requests. Local Modules are modules that are created within the Node.js application. They include different and additional functionalities in separate files and folders to the core functionality package.
Node.JS Architecture: A Detailed Look for Your Next Project
These stages make your application easier to code, maintain, debug and test. Depending on your application, you need to distribute cache across the system. With the pub/sub model, you can implement distributed caching efficiently. As you know, sending event notifications to a significantly node js development large user base can sometimes be highly challenging. You will require systems to deliver the messages to clients rapidly, which becomes an issue when the user base keeps increasing. In addition, sometimes, there is a chance that users may miss out on the message as they’re not available.
- Readable code, which is easier to understand, reduces the need for extensive time and effort spent deciphering the code’s intent.
- „Single threaded” means that all requests to the server are run on the same thread (rather than being spawned off into separate processes).
- With such support, it can be tempting to place our business logic directly in our API routes.
- We’ll begin by defining what Node.js is and give a brief history of its development, before listing some pros and cons, with examples to highlight them.
- The Node.JS platform offers libraries, logic, and types that can be reused across front-end and back-end applications.
A zero-config hosting platform from the creators of the Next.js JavaScript framework. It supports monorepos out of the box and deployments take seconds to complete. Google is heavily invested in Docker and is the creator of Kubernetes (a popular system used for automating app deployment, scalability and management), so the integration with GCP is best-in-class. Node.js also became useful when the company was prototyping a tool for a single-page app. It was a quick way for them to get started and make sure that everything was going in the right direction.

With such support, it can be tempting to place our business logic directly in our API routes. Unfortunately, this approach quickly leads to the creation of large, monolithic blocks that become unmanageable, difficult to read, and prone to decomposition in the long run. If the code of a class, function, or file becomes excessively lengthy, consider splitting it into smaller modules wherever possible and bundle them within related folders. This approach helps in grouping related files together and is essential for enhancing code modularity and organization. In this tutorial, our focus will be the Node.js project structure and architecture. We’ll cover the fundamentals of application architecture in general and discuss some best practices for organizing your Node.js apps.
A CDN or even an S3 bucket works best for serving HTML, CSS, JS files, and images. Node performs best when used for applications that require a lot of IO. If implemented correctly, Node’s single-threaded event loop can provide performance comparable to that of a programme using several threads.
Everything has to have its place in our application, and the folder structure is the perfect place to start organizing things. And I can’t think of any quote that could better describe every developer’s situation when embarking on a new project. Crafting a practical project structure is one of the most challenging aspects of development and a delicate process indeed. Besides this the client folder seems public, so it is worth to serve the whole folder. I used to have all my code in one project (one folder) but then I figured it makes more sense for me to divide it, by logic, to a server folder and to a client folder.
It can therefore be extremely beneficial in compressing the web pages being served by our Node.js servers. These test cases check whether unit components of your code are returning expected outputs or not. For developing these test suites, there are plenty of testing frameworks out there for Node.js developers to choose from. For people starting out in software development, it is quite common to overlook the importance of writing test cases for your code.
That said, updating the version of Node.js you’re working with isn’t the main concern here. This improves flexibility and is especially useful when you hire a new team to implement a change in one microservice. Your development team doesn’t need to go over the whole structure, just the part that needs an update. Implementing well tested design patterns borrowed from other more traditional environments like Java is crucial for later code maintenance. Once you’ve chosen a hosting service and got your project underway, you need to decide on a maintenance strategy.
Good documentation needs to be easily understood and should contain accurate information that helps users get the most out of your software. It should be easily accessible to anyone in the team, and it should explain procedures and problems. If your documentation lacks some important information make sure you update it as soon as possible. It improves velocity development in the long term and makes developers happier and more productive.
