THINK TANKER Node.js is a fast server to work on with its event-driven and asynchronous nature of implementation. But, as per today’s dynamic client’s expectations, it might fall back in the race.

So, how to make sure your Node.js environment is fast enough to fulfill your development project’s purpose?

1. Run in Parallel As you are using Node.js for your web application development project, it is essential that you make multiple internal API calls to fetch various data from the sources.

THINKTANKER.IO

Due to its asynchronous nature, Node.js can respond efficiently while running multiple call functions. The node.js functions are not dependent on each other.

Hence, Node.js is very efficient in running various functions parallel due to its asynchronous nature.

Make sure to make the most out of this feature for your advantage. This small trick will certainly reduce major middlewares and improve the environment speed significantly.

THINK TANKER Without indexing, searching a keyword will be very difficult, making the query extremely slow.

2. Optimize Your Query

The process created by the query in the database dramatically affects the performance of the environment when the end-point generates data called by the system.

A bad query will make the process of displaying data very slow.

Hence, try to optimize your queries as much as possible to avoid the situation of a massive load on the database.

3. Check All Error Scripts with Logging the first thing you need to ensure is that your web app program runs efficiently without any significant errors.

THINKTANKER.IO

The next most important thing you need to do is find this error that is the cause of the trouble. Check out your program code to detect this error. This is where logging comes to the rescue.

With logging, you can easily track the activity and API process traffic. You can use some popular and efficient logging modules for your scripts, such as Winston or Morgan.

THINK TANKER Node.js does not utilize many of the cores that are already available in a system.

4. Clustering Your Node.js

The easy solution of Node.js is to provide scaling up of the app to split a single process into multiple processes. This is achieved through a clustering module.

Cluster on Node.js allows you to create small processes for sharing server ports.

With the help of Cluster, Node.js can handle a large number of requests with multi-core systems. This automatically results in increasing the performance of your server.

5. Use Realtime App Monitor to Analysis your App Real-Time Monitoring needs a third-party application that will allow you to maintain and monitor your application.

THINKTANKER.IO

Monitoring the system will allow you to respond immediately to any potential errors or bugs that might disrupt your app functionality.

+91 90331 55300

With the efficient monitoring apps, you can detect anomalies, find out root causes, and optimize the system performance across your app’s distributed environment.

THINK TANKER If you are fetching some static data in your system that doesn’t change frequently, you may cache it to improve your web application’s performance.

6. Use Caching

Caching static files from your database on the NGINX server can significantly offload some work from the Node.js application server.

Don’t cache the administrative interface for a blogging platform to avoid function disruptions.

The admin guide will enlighten you with multiple options for dealing with successful or failed attempts to find a cache file.

7. Implement a Node.js Load Balancer One of the best ways to improve your web app’s performance running on Node.js is by running multiple application servers and balancing loads across all of them at the same time.

THINKTANKER.IO

Node.js load balancing is not that easy because Node.js enables a high level of interaction between JavaScript and JavaScript code running on the web browser and Node.js application server, respectively.

One of the most significant advantages of Node.js statelessness includes allowing the client requests to be fulfilled by any server with access to a requested file.

8. Use ClientSide Rendering

With the easy availability of many powerful clientside MVC/MVVM frameworks such as Meteor, AngularJS, Ember, etc., it has become extremely convenient to create single-page apps.

You can expose APIs that send JSON responses to the client. While on the client-side, you can use a framework to consume the send JSON and display it on the UI. Sharing the JSON from the server can save significant bandwidth that directly improves the website app speed.

As you don’t send layouts with each request on the server, but just simple JSON rendering on the client-side, Node.js gets space to enable functioning.

9. Don’t Store Excess Data In Sessions If you accumulate too much data in your session, it will add to a significant overhead to the Node.js server.

THINKTANKER.IO

Even though there is no official limit on the data storage, try to break and push it further to create enough space for your efficient app.

+91 90331 55300

You also have the option to switch to some other type of storage with enough space to keep your session data minimum or try to keep track of the amount of data stored in your session and erase it periodically.

Conclusion There are many more efficient ways to improve your web application speed and boost its performance on Node.js.

We hope the above tips will help you work on your Node.js server to run your app correctly.

If you plan to develop your next web app using Node.js, you must take every possible step to make sure your app is faster than usual.

But, if you are still skeptical to perform these functions on your own, you can get in touch with a nodejs development company or hire nodejs developers to help you with the development and optimization of your web application.
