7 ways to improve Node. js performance at scale

1. Frontend tooling. Module bundlers and task runners.
2. SSL/TLS and HTTP/2. When building a Node.
3. Caching.
4. Optimizing data handling methods.
5. Load balancing.
6. Secure client-side authentication.
7. Using WebSockets for effective server communication.
8. Conclusion.

Is Node JS good for scalable?

You definitely don’t want to use Node. js for CPU-intensive operations, using it for heavy computation will annul nearly all of its advantages. Node. js really shines in building fast, scalable network applications, as it’s capable of handling a huge number of simultaneous connections with high throughput.

How do I see node JS application performance?

Express Status Monitor

1. Run npm install express-status-monitor –save command.
2. Then before adding any middleware or router, run app.use(require(‘express-status-monitor’)());
3. Run the server and go to /status.

Why is node so slow?

Node. js programs can be slow due to CPU or IO bound operations. On the CPU side, typically there is a “hot path” (a code that is visited often) that is not optimized. Or, a slow application may have nothing to do with Node; instead, an outside resource, like database queries or a slow API call, may not be optimized.

Why is node so fast?

3 Answers. First, why is a program faster when multi-threaded ? It’s partly due to the fact a multi-threaded program can run on multiple cores but the main reason, by far, is that when a thread is waiting for some IO operation (which is very often, especially in a server), the other threads can still progress.

How to optimize code performance in Node.js?

Someone didn’t do his optimization homework, and we now have to deal with an API where every response takes between 2 to 3 seconds (this is simulated with the setTimeout construct on lines 19-22). This allows to show how different request patterns will result in different runtime characteristics.

Why do we use functions in Node.js?

Writing or using functions or methods in your Node.js code that are executed one after the other gets you a long way in your applications. Sometimes, those functions are simple synchronous steps:

When to think about control flow in Node.js?

The more complex your Node.js applications become, the more you need to think about the so-called control-flow of your code. Especially when the need arises to optimize operations in terms of efficiency and performance by introducing background operations and parallelity, the code can quickly become a mess.

Which is the best book to learn Node.js?

This post is a chapter from The Node Craftsman Book, a comprehensive eBook which teaches all aspects of real-world application building with Node.js, for example: It comes bundled with and extends The Node Beginner Book, an introductionary tutorial to Node.js development, and both books together are available from Leanpub for only $9.00.
