We still have some places left on our Data Manipulation and Visualisation with Python workshop, which runs from 5-9 September 2016 in Edinburgh. This course, taught by dr Martin Jones, founder of Python for Biologists and writer of several Python books, focuses on tools like Pandas, matplotlib, Seaborn and Processing, and is suited for people with a background in biology and basic Python knowledge.

Note that registration is also open for our Introduction to Python for Biologists workshop from 12-16 December 2016 and our Advanced Python for Biologists workshop from 12-16 June 2017.

What is Node.JS?

Node.Js is an open source and cross-platform runtime environment for executing JavaScript code outside of a browser quite often we use no to build back-end services also called API's or application programming interfaces.

These are the services that power our client applications like a web app running inside of a web browser or mobile app running on a mobile device. These client apps are simply what the user sees and interacts with, they're just the surface they need to talk to some services sitting on the server or in the cloud to store data, send emails or push notifications to kick off workflows and so on.

NodeJs is ideal for building highly scalable data-intensive and real-time back-end services that power our client applications. Now you might ask but most there are other tools and frameworks out there for building back-end services such as Spirit, Rails, Django and so on. What's so special about Nodejs is easy to get started and can be used for prototyping and agile development but it can also be used for building super fast and highly scalable services.

It's used in production by large software development companies. In fact at PayPal that rebuilt one of their Java and spring based applications using nodeJs and it found that the node application was built twice as fast with fewer people in 33% fewer lines of code and 40% fewer files and more importantly they double the number of requests served per second while decreasing the average response time by 35%.

So nodejs is an excellent choice for building highly scalable services.

Another reason for using nodejs is that in node applications we use JavaScript. So if you're a front-end developer and know JavaScript you can reuse your JavaScript skills or you can hire reactjs development company. A full-stack developer can get a better job with better pay. You don't have to learn new programming languages. Also because you can use JavaScript both on the front end and on the back end your source code will be cleaner and more consistent.

So you will use the same naming conventions, the same tools and the same best practices. And finally another reason for using nodeJs is that it has the largest ecosystem of open source libraries available to you, so for pretty much any features or building blocks you want to add your application there is some free open source library out there that you can use. So you don't have to build this building blocks from scratch and instead you can focus on the core of your application.
