nodejs and IoT: a match made in heaven

The world is becoming digital and hyperconnected. This is the reason we see more and smarter locks, smart glasses and other wearables, and also advancements in home automation and vehicle automation, etc. Thus, there is a huge scope of Internet of Things (IoT) in particular, and smart businesses know this.

This is the reason we see more and smarter locks, smart glasses and other wearables, and also advancements in home automation and vehicle automation, etc. Thus, there is a huge scope of Internet of Things (IoT) in particular, and smart businesses know this.

The Rise of Node.js

There are a variety of programming languages that one can use today such as Python, Java, C++, Ruby, and more. However, none of these can be applied as “one size fits all” technology for disparate tech products. In addition to that, with time, newer technologies emerge which offer better support and better services and thus replace the old technologies. Node.js is one of them.

Node.js is a server-side runtime environment and is commonly used to build large and scalable web applications. It’s powerful but at the same time easy to learn because almost every software developer has once worked with JavaScript in their life at some point.

Programmers love Node.js because it has:

  • Low resource requirements. Thus, system processor and memory are not overburdened.
  • Support for building scalable applications, which is really important for every company today.
  • Great compatibility with JSON, a popular format that allows for an easy and quick exchange of information across a network.

The global tech giants were quick to realize the significance and potential of the Node.js technology. While Microsoft adopted the same for its Azure platform, payments leader PayPal picked it for its website to handle the massive volume of transactions that it has to process every day, as well as to increase the security. Other noted companies that have embraced Node.js include Uber, Netflix, and even IBM!

Why is Node.js Perfect for IoT?

Node.js is built on Google’s V8 open source JavaScript engine and widely known for its impressive scalability and efficiency. Thus, it’s well-suited for real-time applications that are highly data-intensive. Since IoT applications too are data-intensive and work in a real-time environment, they are a natural fit for this technology.

The following are some of the ways how Node.js can greatly help in building IoT applications:

  • A large number of IoT applications use MQTT protocol and the standard Sockets which have a great support in Node.js.
  • The executable codes for many IoT devices are written in low-level languages like C++, etc. which could be challenging to work with. However, if you are working with inhouse developers as opposed to outsource development, Node.js is simple and easy to understand for even the inexperienced software developers.
  • The Node Package Manager (NPM) comes with several useful IoT modules. It contains more than 80 packages for Intel IoT Edison, Rasberry Pi, and Arduino Controllers. It also contains more than 30 packages for a variety of Bluetooth devices and sensors. These greatly help to speed up and simplify the application development process.
  • Since the IoT devices viz. sensors, motors, transmitters, etc. generate large volumes of data and a large number of requests, Node.js is apt for handling these. This is because it has an excellent support for streams which offer readable and writeable channels for request management, as well as temporary storage of data.

IoT is one of the fastest growing technologies we have today. Since Node.js allows you to make the most of it easily without compromising on the results, it definitely pays to invest your time and energy into it.




Top 7 Most Popular Node.js Frameworks You Should Know

Top 7 Most Popular Node.js Frameworks You Should Know

Node.js is an open-source, cross-platform, runtime environment that allows developers to run JavaScript outside of a browser. In this post, you'll see top 7 of the most popular Node frameworks at this point in time (ranked from high to low by GitHub stars).

Node.js is an open-source, cross-platform, runtime environment that allows developers to run JavaScript outside of a browser.

One of the main advantages of Node is that it enables developers to use JavaScript on both the front-end and the back-end of an application. This not only makes the source code of any app cleaner and more consistent, but it significantly speeds up app development too, as developers only need to use one language.

Node is fast, scalable, and easy to get started with. Its default package manager is npm, which means it also sports the largest ecosystem of open-source libraries. Node is used by companies such as NASA, Uber, Netflix, and Walmart.

But Node doesn't come alone. It comes with a plethora of frameworks. A Node framework can be pictured as the external scaffolding that you can build your app in. These frameworks are built on top of Node and extend the technology's functionality, mostly by making apps easier to prototype and develop, while also making them faster and more scalable.

Below are 7of the most popular Node frameworks at this point in time (ranked from high to low by GitHub stars).

Express

With over 43,000 GitHub stars, Express is the most popular Node framework. It brands itself as a fast, unopinionated, and minimalist framework. Express acts as middleware: it helps set up and configure routes to send and receive requests between the front-end and the database of an app.

Express provides lightweight, powerful tools for HTTP servers. It's a great framework for single-page apps, websites, hybrids, or public HTTP APIs. It supports over fourteen different template engines, so developers aren't forced into any specific ORM.

Meteor

Meteor is a full-stack JavaScript platform. It allows developers to build real-time web apps, i.e. apps where code changes are pushed to all browsers and devices in real-time. Additionally, servers send data over the wire, instead of HTML. The client renders the data.

The project has over 41,000 GitHub stars and is built to power large projects. Meteor is used by companies such as Mazda, Honeywell, Qualcomm, and IKEA. It has excellent documentation and a strong community behind it.

Koa

Koa is built by the same team that built Express. It uses ES6 methods that allow developers to work without callbacks. Developers also have more control over error-handling. Koa has no middleware within its core, which means that developers have more control over configuration, but which means that traditional Node middleware (e.g. req, res, next) won't work with Koa.

Koa already has over 26,000 GitHub stars. The Express developers built Koa because they wanted a lighter framework that was more expressive and more robust than Express. You can find out more about the differences between Koa and Express here.

Sails

Sails is a real-time, MVC framework for Node that's built on Express. It supports auto-generated REST APIs and comes with an easy WebSocket integration.

The project has over 20,000 stars on GitHub and is compatible with almost all databases (MySQL, MongoDB, PostgreSQL, Redis). It's also compatible with most front-end technologies (Angular, iOS, Android, React, and even Windows Phone).

Nest

Nest has over 15,000 GitHub stars. It uses progressive JavaScript and is built with TypeScript, which means it comes with strong typing. It combines elements of object-oriented programming, functional programming, and functional reactive programming.

Nest is packaged in such a way it serves as a complete development kit for writing enterprise-level apps. The framework uses Express, but is compatible with a wide range of other libraries.

LoopBack

LoopBack is a framework that allows developers to quickly create REST APIs. It has an easy-to-use CLI wizard and allows developers to create models either on their schema or dynamically. It also has a built-in API explorer.

LoopBack has over 12,000 GitHub stars and is used by companies such as GoDaddy, Symantec, and the Bank of America. It's compatible with many REST services and a wide variety of databases (MongoDB, Oracle, MySQL, PostgreSQL).

Hapi

Similar to Express, hapi serves data by intermediating between server-side and client-side. As such, it's can serve as a substitute for Express. Hapi allows developers to focus on writing reusable app logic in a modular and prescriptive fashion.

The project has over 11,000 GitHub stars. It has built-in support for input validation, caching, authentication, and more. Hapi was originally developed to handle all of Walmart's mobile traffic during Black Friday.

Difference between AngularJS, React, Ember, Backbone, and Node.js.

The most common thing between all of them is that they are Single Page Apps. The SPA is a single page where much of the information remains the same and only some piece of data gets modified when you click on other categories/option.
