The performance of every web application is the most crucial factor for web application development. An efficient web application is fast and beneficial for users, developers, business stakeholders and others. Because of this, there will be no frustration for the users using the application.
One of the best frameworks is to building a web application in Node.js. For those unaware of this platform, let us tell you that it is the PHP-based framework that provides the best features to enhance the speed and performance of applications. Will your Node.js application be able to manage high workloads? If it does not happen, users will get a degraded experience.
This article talks about more practices that help in scaling Node.js applications. In this guide, we will highlight all the necessary tips to enhance the speed and performance of the Node.js application, And it will give you an edge to succeed in the market. Additionally, it’s essential to consider reliable nodejs hosting including the cheapest domain hosting, to ensure optimal performance and stability of your application.
How to Scale Your Node.js Application?
1. Monitor the Performance Level
Before you attempt to improve the performance of a system, it’s necessary to measure the current level of performance. This way, you’ll know the inefficiencies and the right strategy to achieve the desired results. Gauging the current level of performance of an application may require running different kinds of tests, such as the following:
- Load Testing: It is a practice of simulating the usage expectation of the system and measuring the workload response.
- Stress Testing: With this measure, you can design to measure how a system performs beyond the limits of normal working conditions. Because of it, users can easily determine how much workload a system can handle.
- Spike testing: To help you with test behaviour, use this measure to determine the rate of increase or decrease in load.
- Scalability testing: This testing method determines when the application scales up. With this step, you’ll also understand the reasons behind it.
Additionally, it’s essential to consider reliable Node.js hosting services and incorporate a free SSL certificate. These elements contribute significantly to the security and accessibility of your application, ensuring a seamless experience for users while prioritizing data protection and encryption.
2. Reduce Latency through Caching
The common strategy to enhance the performance of Node.js applications while scaling is caching. The main objective is to increase the data retrieval speed by spending less time computing data or following Input/output measures.
Remember that cache is a high-speed storage layer to store temporary data. Using this storage, user can frequently access their data, and you don’t have to retrieve the data from primary resources every time.
As a result, applications will receive many requests for unchanged data. Moreover, responsiveness to such requests will also increase, and server resources will not fail unnecessarily by repeating the work to compute such data.
3. Use Timeouts When Dealing with I/O Operations
Timeouts are the easiest things when most of your operations go wrong. Your server might not respond to external services or become unresponsive. Thus, server activity will get slower for end-users.
When building Node.js applications, timeouts are amongst the easiest things to get wrong. Your server is probably talking to other external services that are also calling other services. If one service in the chain is slow or unresponsive, it will result in a slow experience for your end-users.
You cannot guarantee that your dependencies will always respond as fast as they normally do, so timeouts are important even if you don’t run into this issue during development.
Depending on the request, a timeout can be set. Clients use this parameter to indicate how long they will wait for an external service’s response. A connection will be aborted if the answer is not received within the specified timeframe, so the application won’t hang indefinitely. Node.js libraries for making HTTP requests (such as axios) do not set a default timeout, so remote APIs can keep your application waiting indefinitely for the requested resource.
4. Don’t Serve Static Assets with Node.js
For best performance, keep static assets such as JavaScript, CSS, or image files from your application off Node.js servers. As Node.js wasn’t designed for this use case, serving assets from the main application consumes valuable resources and delays important business calculations. Use a web server like Nginx to serve static files, as it can perform optimizations that Node.js cannot. According to this test, Nginx delivers static assets twice as fast as Node.js (using Express static middleware).
Setting up a CDN proxy, such as Amazon CloudFront, to cache your static content and offer it to end users as feasible is another method for serving static files. As a result, the Node.js servers are now free to handle only dynamic queries.
