“For the second year in a row, Node.js takes the top spot, as it is used by half of the respondents. ” -- Stack Overflow
In this post, I’m going to talk about the pros and cons of Node.js for backend development. But before that, let’s discuss a few important things about this programming tool.
Node.js is a modern software development tool used for several purposes including back-end development. It is neither a framework nor a library. It is also not a programming language.
Similar to other server-side technologies, this tool also lets you fetch data from databases and add, delete, and manage them.
Download link: Get Node.js.
With this amazing development tool, you can make command-line tools, server-side web apps, neural networks, chatbots, desktop applications, high-performance real-time chat apps and the like.
Here’s a list of companies using Node.js:
LinkedIn: LinkedIn has switched from Rails to Node.js for their mobile app’s backend development. VB interviewed LinkedIn’s mobile app development lead Kiran Prasad and asked him to share their team’s development experience with Node.js.
Medium: Medium has used Node.js for the development of their web servers. This post by a senior engineer at Medium gives greater insight into their software stack and how they do engineering.
eBay: eBay engineer Senthil Padmanabhan talks about their Node.js development journey in this article. The eBay engineering team was open to new development tools and saw awesome results after choosing Node.js.
Other top Node.js users are NASA, Yahoo!, Uber, Trello, Groupon, Walmart, Home Made, and so on.
Here are the major advantages of using Node.js for building backend solutions:
Lightning-fast speed: One special thing about Node.js is that you can make high-performance apps that scale well.
Node.js has the ability to handle a large number of requests at the same time. It runs single-threaded and can handle many, many concurrent connections.
As this programming tool utilizes a non-blocking input/output model, no functions are blocked when an I/O operation is performed.
Fast app development with NPM: Node Package Manager gives you a large number of package modules for different types of development tasks and helps you complete your project quickly. Packaged modules are frameworks and libraries.
Modules from NPM come with high-quality code which will help you build high-quality software.
Development flexibility: Node.js doesn’t have strict rules. So you can build your project how you want. You can build things from scratch.
Amazing business benefits: Node.js gives you great business advantages such as reduced development costs, improved developer satisfaction, increased app performance, increased uptime, and so on. It can help you boost customer satisfaction and customer engagement.
Great community support: On GitHub, Node.js has 2,892 contributors that are working to make improvements in this tool. This number is growing gradually.
Not a good fit for small projects: Node.js is ideal for large projects. If you try to complete a small project with this tool, you will end up spending more time than required. For small projects, you may use other web development technologies such as Laravel, Ruby on Rails, and Django.
Not good for server-side computation: Node.js is not a good fit for projects that involve heavy server-side computation. The use of this tool for such projects will negatively affect your app’s performance.
Unstable API: As the APIs of Node.js change very often, the developers may have to repeatedly make changes to their code so they are compatible with the new versions of the APIs, as they are not backward-compatible most of the time.
The best Node.js tutorials and courses are mentioned below. Some of them are paid courses while others are free of cost.
In this post, we covered a brief overview of the origins of Node.js, how it’s evolved within the developer community and some of its strengths and weaknesses. At Tempest House, we have mastered Node.js over the years. If you’re looking for help, book a call with one of our experts here.
