Each programming language has its benefits, but Node.js is highly favored in Silicon Valley and all around the world. It lets you develop a real-time data-intensive application, has a low learning curve, and is useful for building microservices.
However, it is not that simple. Working on a Node.js project, you should be ready to meet some challenges. Sometimes, the development process is just slow, and it seems there’s nothing that can help it. Sound familiar?
Fortunately, the TechMagic team is ready to share our experience and provide you with powerful insights on how to advance the Node.js development workflow.
How to Accelerate Node.js Development: Challenges to Overcome
One of the reasons why TechMagic doesn’t face difficulties with Node.js is that our team uses the best practices. However, newcomers get lost even in the friendly open-source community as there are many options to go. While prioritizing speedy delivery over perfect code, the development team might end up making extra effort to improve the software or to add functionality later.
What you should do is implement some proven patterns. Try borrowing from Java and other more mature ecosystems.
Our developers faced this issue at the start of their careers. Usually, while working with mature frameworks, you expect some clear guidelines for coding, but the Node.js frameworks simply don’t provide it. Different practices and a high degree of variations inside the development team result in a dirty code and prolonged coding time. Accelerating Node.js development requires an individual approach for each project, just accept it.
Whether you’re a Junior or a cautious and experienced Senior, you’ll not dispute the importance of documentation for any IT project. The main thing for each team member in the development process is to understand how the app works. Where do you find the answer? It is documentation that is supposed to be structured and well-designed.
Choose the Right Direction
Even though Node.js is still a relatively young environment, that doesn't negate its many benefits. In many cases, it proved to be effective for such companies as Mozilla, PayPal, eBay, Walmart, etc.
All you need to do is to choose the right direction. We’ve prepared some actionable tips to improve Node.js skills, and they’ll save you some time. Or you can contact a team with a professional approach, well-established processes, and guaranteed results.
10 Strategies to Speed Up Node.js Development Process
Building web applications, you make internal API calls sometimes and get various data. Here are some hypothetical options:
Retrieving these details, developers create a separate middleware for each function. Once they have it done, they attach it to the dashboard route. However, using this tip, we’ve also met difficulties. One function must wait until the previous one is completed, which slows down the process a little.
So, we’ve found a way to speed up the process of Node.js development. We just parallelize things. And it works because of the environments’ asynchronous nature.
Seasoned Node.js programmers prefer to use an asynchronous approach in web development as it avoids blocking threads. At the very least, you should try it in departments that are in critical charge of the performance.
For example, the synchronous code is acceptable if we build a script for working with a database, not a system for processing parallel or concurrent tasks.
What is the distinguishing feature? The difference is whether you are writing long executable code or a small script with a short lifetime. In general, remember one good Node.js rule from professionals: Always write asynchronous code.
Just Cache It
When working with data that doesn’t change too often, we just cache it to hasten the Node.js development process. You can see the example in the snippet below.
If your blog posts don't come out very often, cache the array of posts and clear it after a while. In the next snippet, you see how you can do this using the Redis module. So, start by checking for messages in the Redis cache. After that, you can deliver an array of messages or get content from the database and only then cache it. After a while, you will be able to clear the cache and create new content.
Knowing that some parts of the code can be run only once, such an implementation will be useful.
Use gzip Compression
This is another factor that affects the performance of your app. We’ve mentioned that the browser needs much more time to load statistics resources if we don't use the compression middleware.
Lowercase Is King
Of course, we like encouraging file names to match class names. However, you need to use lowercase files. Myclass.js and myclass.js are equally well for some operating systems, but, for instance, Linux can’t handle it. An easy step to decrease the time for Node.js development is using lowercase.
Cluster Your App
Be aware of the Node execution time limits, which lead to a huge waste of resources. Even if you only need to run one process on very little hardware, for now, cluster support will give you flexibility in the future.
It is important to take care of the environment you live in, sort garbage, and plant trees. Use this approach everywhere because environmental awareness affects your project, as well. If you want to speed up your Node.js development process, don’t litter your app with configuration files. Our choice is environment variables.
You shouldn’t rely on the Node garbage collector only. Sometimes it waits for the last moment to free the unused memory. Don't worry about the leak, and if memory usage starts to increase, just provide flags in your Procfile.
Update the Stack
Keeping your Node.js version up to date lets you boost application performance and your developers’ work. Various ES6/7 features will provide a more robust stack even without the need to install transpilers.
When speeding up the Node.js coding, remember that you need to tackle the problem’s root, not the surface level. Perhaps you have a weak machine, a flaw in a part of the code, or not-implemented automatic scaling. Narrow down the problem first, and after investigating, you can determine the next steps. Also, take care of registering the application’s behavior, which will help you understand the problem’s essence.
However, there is still one more option: hire an experienced and reliable team. TechMagic is always here to have your back, share our vision and best practices, and exceed your expectations.
