Information System of Node.JS Application - Essay Example

Information System Report about Node.JS Executive Summary Node .js is considered to be a cross platform that is an open source used in the development student information in term of profiles. The application is built by using the JavaScript runtime that is the best in creating networks that are scalable. In every organization there exist clients that use web applications like Mozilla Firefox to access office files from servers of the organization. Node.js is capable of creating a reliable environment and be able to connect the database to the web browser renders. The development of the web has really changed creating different changes in the world of JavaScript. The kind of applications running is unimaginable since they are effectively connected to the web for clients and the server for organizations. The applications are then encapsulated to other environments like flash and Applets of Java. The main aim for Node.js is to create websites that are able to have a push and real time capability. Introduction The application Node.js was introduced in the year 2009 and it was created by Ryan Dahl. It is a platform environment that is built with a JavaScript background that is supported by Google Chrome’s JavaScript engine that is the fastest among other JavaScript engines. The application has a large number of users online using it including web developers. The application is able to accommodate a large number of users due to its scalability. With the function, Node.sj has been accepted by a large number of organizations including Facebook and EBay. The application is known for having an ability of becoming event driven which allows the web browsers to respond only when the user responds or performs a function. The resources spent when a web browser is running is much less since the application allows the browser only to respond when a user is working and it enables the connection in that same period. This is an environment that has been applied in a large number of institutions and organizations including Passmores University. In the university, Node.js is widely used since it has a number of characteristics that adhere to the rules of the environment. There are a large number of students registered at the university using web browsers. The same number of the students increases every year. Due to the scalability of the environment, all the students are being recorded into the servers inclusive of their academic and administrative records. In case information in the database is altered, it is able to be reflected in other user (Students and administrators) (TEIXEIRA, 2012). Recommendation + Evaluation Node.js is known to be an open source tools since it is the main future of the development of software and its programming. When working with an open source application everyone is able to contribute and rectify where the problem can be. It’s recommended that developers should join hands together and contribute to the development of the web based application that uses Node.js. With the sources of Node.js, they can easily be downloaded and saved which makes the library to configure and save automatically by using the IDE. But also bear in mind that a number of open source tools are not the best when it comes to privacy and privacy matters. With open source one is able to come up with a back up that can be developed and be improved by other software developers. At the same time, this can be a threat to an application in terms of privacy and protection. Such web applications are easily infected with threats like viruses, worms and theft. Viruses like Trojan viruses like overflowing in such open source web applications because they are often used by a number of developers. Unluckily, not all developers have a positive motive towards all the open source web applications. For the professional developers using Node.js, it is able to come up with the required architecture that will support and enhance the coding ability for the application. It is also easy to help other professional developers in creating the right architectures leading to the right designs in the field of technology in the entire globe. It should also be noted that note all the languages can be of support to the architectures being developed by using the Node.js environment platform. With the help of the intelliJ IDEA, Node.js offers an excellent assistance when coding using the JavaScript development of the syntax (ASSUMPCÃO, 2013). It is easy when coding and completing the navigation of the code. With the module of CommonJs, there are several options of completing the execution when coding. It is recommended that developers should use the intelliJ to code and complete the navigation and also execute the coding. At the same time, errors like complex functions when coding can be a threat to the application. It is also true that CommonJs has got unseen errors that can be made during coding. All the applications that use the environment of Node.js can be run and be debugged in order to view the output in the IDE. The debugger of the JavaScript in the applications is able to have a breakpoint that has smart steps and watches. This also includes the expression evaluations of the applications among with other numerous functions. It is also recommended that during coding the data should be run and be debugged by using the IDE. On the same note, when debugging, some information can be lost and at the same time, error may not be identified easily. With the help of the IntelliJ, it is easy for developers to run and debug the unit tests by using the node unit. When done, it is easy to understand the test definitions and be able to jump on the errors in the IDE (ASSUMPCÃO, 2013). Well, a number of senior developers find Node.js to be simplifying codes making it to be of importance and saving time. The codes are made simple by using intelliJ creating a better coding experience. At the same time, other developers do not accept that fact but instead they term the application to be not of use. There is only one simple trick to all the software developers whereby they learn to understand what a project will benefit from a system using Node.js applications. References ASSUMPCÃO, H. O.
