6 Ways which will Uplift and Improve the Performance of Your Node.js App

As a respected and widely acceptable programming language, Node.js is used for creating server applications in JavaScript. Since this language offers the functionality of both a web server and an application server, hence it is considered as a prime tool for all types of microservices-based development and delivery. Node.js embraces its developers with an event-driven architecture and a non-blocking I/O API that optimizes your application and also improves the scalability. That’s why developers are preferring Node.js for backend application development. If you want to develop a functional and compelling Node.js application, you should hire Node.js developers from an eminent development company.

Though Node.js has a plethora of advantages over other programming languages, still, it has some weak points and vulnerabilities that lessen the speed of a Node.js-based system. The problems become noticeable when a Node.js-based application receives huge traffic growth. In this article, we are going to mention some tips which will optimize and improve the performance of your Node.js app.

    1. Caching your app by using Redis: Redis is an intricated version of Memcached which helps in the caching process. Redis is capable of serving and modifying data in the main memory of the server. As a result, the system can quickly retrieve data which is needed. Redis also minimizes time to open web pages and makes your site quite faster. By creating an outstanding in-memory cache to lessen access latency, Redis improves load performance from relational databases or NoSQL. By using Redis, now, you can store cache using SET and GET. Moreover, Redis also works well with other complex data type lists like Lists, Sets, ordered data structures, and so on.
    2. With logging, check all error scripts: Why logging plays an imperative role in your application programme? While making an app, you make sure that your application programme runs smoothly without any error. If you find something unusual in your programme, you should find out what code makes that error. Now, you can track activity and API process traffic by using logging. The logging process that many people prefer, and apply is to use console.log (‘Log Output’). By default, this inserts some logs on the output standard (stdout). But it would be a wise decision if you use a popular and efficient logging module like Winston, Morgan and Buyan. At first, you need to install Winston and include it on the new project. Run the below-mentioned command to do this job.
    3. Use real-time app monitor for your app analysis: Real-Time Monitoring is a useful third-party application. By using this application, now, admins can maintain and monitor the system from any problems which arise in web applications in real-time. This application allows you to respond immediately and fix any bugs that occur. You can use Newrelic, Stackify, Ruxit, LogicMonitor and Monitis in Node.js to record traces and activities quickly and succinctly. With the help of this monitoring, you can find out more detailed issues like the effectiveness and overall condition of node.js when is accessed by many users.
    4. Clustering your Node.js: Node.js indeed runs on a single thread on a single core of the processor. This is the default function of Node.js. Node.js doesn’t utilize several other cores that are available in a system. With the help of cluster on Node.js, now, you can easily create child processes which all share server ports. This cluster can manage and handle a chunk of requests with multi-core systems. This will automatically enhance the performance of your server.

  1. Use gzip compression: Gzip is popular software which is particularly used for file compression and decompression. Today, gzip is supported by most of the servers and clients. When a gzip compatible browser sends a request, before sending it to the browser, the server can compress the response. This can minimize time lag and latency. You should use gzip when you need to respond to clients as well as while making requests to remote servers. This can surprisingly improve the overall performance of your apps.
  2. Optimize your queries: Suppose your blogging app displays all the latest posts on the home page. Using Mongoose, you can write something like this to fetch data.Post. find (). limit (10). exec (function (err, posts) {// send post to the client});Now, the problem is that in Mongoose, the find () function fetches all the fields of an object.   But there might be many fields in the Post object which are not at all necessary on the homepage. For example, the comment is such a field which holds a plethora of comments for a particular post. Since comments are not showing on the home page, hence you can exclude it during fetching. This will certainly improve the speed of your application. To optimize the query, you can write this command.Post.find(). limit (10). exclude(‘comments’). exec (function (err, posts)// send post to the client


    These are the top 6 ways which will improve the performance of your Node.js app. With the help of the internet, you can find many more ways which will uplift the speed of your application.
