WHY CHOOSE NODE.JS?
- Asynchronous, Single-threaded, Non-blocking I/O
- Highly Scalable
ASYNCHRONOUS, SINGLE-THREADED, NON-BLOCKING I/O
The first advantage that Node offers is increased performance thanks to its asynchronous, single-threaded, non-blocking I/O capabilities. A lot of other server-side technology is thread-based, meaning a new system thread, or connection, is created for a request to the server. The thread persists until the request has been completed, with the thread waiting for read/write operations, such as uploading or downloading a file or retrieving a file from a drive. This can be computationally expensive, putting a drain on system resources if too many threads are running at the same time.
For a simplified real-world example of how this works, consider a fast food restaurant: When a customer comes in and places an order with person at the cash register, this is the same as a client making a request to the server. Imagine if when the employee at the register takes an order and passes it to the kitchen, they then go off to the kitchen to prepare the food before moving on to the next customer; this is similar to how blocking I/O works. The queue will continue to grow until another cashier opens a register, which in this case is like an additional thread.
Instead, upon receiving the order, the cashier passes it onto the kitchen, who sets about making the food. Now, in some cases, if the food is already made or easy to prepare, like a drink or ice cream, the cashier can give it to the customer straight away, so they leave the queue. Others take a little more time, so the customer stands to the side while it’s prepared, and another customer is served. This is the equivalent of a request going into the event queue. Eventually, when the food is ready, the customer is served and leaves the queue – much like a request being fulfilled and leaving the event loop.
Node’s event-driven model directly ties into the its second advantage — the fact that it’s highly scalable. Because it's single-threaded and doesn’t place a significant drain on system resources, it’s easy to run multiple instances of the same application. What’s more, Node has the in-built capability to scale on a single machine or multiple machines; which allows for efficient horizontal scaling.
This makes Node ideal for rapidly growing businesses that regularly see increased traffic to their site or application, as well as those with strong seasonal demand with sharp bandwidth increases at certain times of the year.
This will result in a faster, more robust, and better-performing application which is much easier to develop and maintain. This also leads to faster, more efficient and more cost-effective development as there’s way less configuration between different platforms and technologies.
NODE.JS AND FRONTIT
We have a lot of experience in implementing back-end apps and services with Node and know how it can drastically improve an application’s performance. We can help you:
- Create back-end services and apps
- Replace your existing back-end services
WHY CHOOSE US?
Our developers know how to take advantage of the powerful framework, libraries and tools on offer to create different components of your application. This includes Express.js, which is a framework for building web server applications. As it gives developers lots of ready-made components for creating apps, instead of having to code them from scratch, they can develop faster.
We also know how to make use of Node while following Agile development practices, where the creation of software and applications is broken down into smaller stages, with each one resulting in a working prototype of the desired end result. Working in this way, Agile development leads to more performant and robust applications delivered on-time and within production budgets.
