Benefits Of Node.js And Why Startups Are Switching to It? (Infographic)

As the mobile industry is continuously blooming and presenting young developers with new opportunities, they are also faced with an important decision that will pretty much determine what their app developing experience will shape up to be. To be more specific, we’re talking about choosing a development platform. Sure, there are still developers that prefer to use another platform, but from a popularity standpoint we are seeing a blanket of Node.js users on the rise. As up and coming developers are looking at the developing platform to help them carry out their project, we are going to look at why Node.js is a great development platform for startups. With big names such as Walmart and PayPal but also smaller yet popular ventures like Slack or Uber finding their way towards Node.js, one can only wonder if the platform really is the best solution right now. That being said, check out these Node.js perks that you will benefit from if you decide to adopt the development tool into your startup creation process. It scales The capability of scaling accordingly is something that drives many developers towards choosing Node.js. This functionality comes into effect when talking about software stacks. From a server side perspective, developers choose to build their software stacks on Node.js completely. Startups aren’t the only ones that benefit from this, as it is noticeable in several established brand examples. Among these examples we can find the likes of LinkedIn, eBay or even Groupon, and thanks to Node.js they are able to distribute large workloads onto servers while displaying unparalleled performance parameters. Quick to respond The amount of time in which a server responds while being in the midst of testing is very important as it lays down the foundation for the startup performance overall. The advantage of using Node.js over another development platform can also be found in the speed with which Node.js developers are able to get a response. This is due to its light nature and the fact that it doesn’t clutter up with app servers and JARs that can otherwise slow it down. As a result, developers find themselves free to focus on writing the code and deploying it just as quick. Also an important factor in why Node.js is so fast is the fact that it uses the same language for frontend and backend, so that there’s no need to alternate between the two. For someone freshly getting a startup going, it can be a huge relief not having that extra thing to worry about. Easy to learn, easy to use Since we’re talking about startups, it only makes sense that we assume that most of the people creating them will be novices on the development scene. This can be quite daunting when dealing with other platforms which require a tremendous amount of work and will to learn, just to get down the way it works. With Node.js, the learning curve is quite manageable. In fact, you’ll be a Node.js expert in no time. As mentioned before, the front and backend use the same language which means that a substantially smaller amount of code has to be written in contrast with a scenario where frontend and backend don’t use the same language. Micro services Micro services come in the form of an architecture type and bring forth a series of perks that users can benefit from, just by using Node.js. Customer count scaling, increased speed and safety for writing code, extensive testing capabilities in an A/B format, and customer feedback facilitation. These are the features you can include in your tool box if you are to embrace the micro service architecture designed within Node.js. Community perks Getting a great service is always a good thing, but it’s always better if you have a community of peers to rely on for occasional help. When you are part of a community, problems get fixed ten times faster and also knowledge is gained at accelerated rates as well. Thanks to the overflow of great features and functionalities, as well as its smooth learning curve and easy to code nature, Node.js is rapidly garnering popularity and a strong community around it which can be a very useful tool when you find yourself in the dark as a starter developer. Conclusion That being said, Node.js is a great choice for people that want to get straight into the action and proceed to doing without having to spend huge amounts of time learning the software first. The array of functionalities give Node.js an edge over its competitors and keep users satisfied during their projects.

Major Node.JS Pitfalls Committed by the Developers

Today Node.js has outclassed other web applications in the competition to establish as one of the optimum server based platform. It has been predominantly developed on the JavaScript Engine of the most popular web browser- Google Chrome, which is the V8 Engine. Node.js helps in establishing the two-way communication between the client and the server in real time so that the sharing of the files, documents and data becomes much simpler. One of the key factors that has made Node.js popular within the users is its swiftness to create scalable network applications. It is light-weighted and effective application that has non-blocking I/O model and can smoothly operate on a number of distributed devices. According to statistics, Node.js is used by 0.3% of all the websites. One of the other research shows that division in percentage on how the organizations are utilizing the benefits of the Node.js. According to that 39% is getting used for backend, 36% for full stack, 16% for front-end whereas the remaining 9% for others. With various advantages under its belt, Node.js is supposedly the preferred framework when it comes to development of complex applications. Although it is known for its simplicity, efficiency and reliability, however, still the developers need to have an insight on how to maximize its utility. The Common Node.js Mistakes Made by Developers During the building of the application, the developers commit some mistakes that can even lead to an entire project failure. So, it becomes important to know about the pitfalls in advance so as to remain alert and careful while developing application. Continuously Pressing for Call Backs One of the common mistakes often committed by the developers is implementing the callback function more than once. As such even today the JavaScript relies much on the process of the callbacks and it helps in connecting the asynchronous elements, thus making them to function appropriately. In fact, call backs are identified as one of the crucial aspects of Node.js and it also assists the developers to build APIs. So if the developer is going for the call back for more than one time, he creates the problem as it affects the functioning of the Node.js. It is important to get the value of the first call function. One of the best ways you can avert this mistake is add a return keyword before undertaking the call back task. It must be remembered that most of the tasks are asynchronous and so the return call back does not make any sense. Blocking of the Event Loop As a developer you need to know that an event loop is one of the vital tasks being carried out by the Node.js in developing the complex applications. However, the problem arises when the event loop gets blocked and as an outcome the user has to wait a longer period of time for navigating the app. In simple terms the connection with the server gets disrupted. The program functions on a single line and so you cannot run two applications at the same time. Therefore, if the event look gets obstructed then it will affect the entire program. Thus, it is not a worthy advice to pair the event loop with excess payload of JSON. parse with the intention of focusing on backend files. It becomes the responsibility of the developer to identify what type of common mistakes are getting along during the coding and should remove it, so that the application can run seamlessly. Nested Callback or Callback Hell If you properly analyze the common issues with Node.js, you would know that most of the problems are associated with callbacks and the callback hell or nested callback, whatever you may term it is one of the general mistakes. In fact, this particular problem persists in most of the application development programs. The concern usually originates because the development of the application is a complex process. It also becomes difficult to maintain the codes. But you can sort out this issue by writing simple functions that are easy to read and providing them suitable links. For instance, codes such as Generators, Promises etc. will be helpful and you can keep the codes error free. The developers who expect that the call back will operate serially shouldn’t get under this misconception as everything is not carried out synchronously. Therefore, it is suggested that the addition must be done instantly after the call back to ensure everything goes smoothly. Forgetting to Test and Inspect the Codes So, once an application development is complete it’s time for some more action as the developer has to mandatorily test and inspect the codes. Well, in order to carry out this work in a smooth manner, he can take the help of various tools, which remains at his disposal. A few examples of these would include Jasmine, Mocha etc. Mere testing of the framework is not considered adequate as he also needs to conduct an inspection on different features such as how much memory is being utilized and delay in the event loop etc. For the inspection purpose, the developers can take the support of viable tools including App Dynamics and New Relic. However, in case you are doing the manual coding, then it is recommended to add a few more programs to offer the robustness to the program. Developer is Unknown to Developing Tools Often it is seen that in case the developers are inexperienced and fresher into the application development field, he remains unknown to the developing tools. It has already been indicated earlier that Node.js helps in complicated application building and if the developer is not familiar with the basic modules he may face problems. The developer should know that if any change is done at the source, he has to restart and also he needs to refresh the browser when the static codes are getting modified and affecting the performance of the application. For restarting the server, you can use modules such as nodemon and for refreshing the nodemon
