Node.js is a free open source server that works on various platforms like (Windows, Linux, Unix etc. It was initially inscribed by Ryan Dahl in 2009. Node.js has an event-driven architecture which leads to optimization in throughput and scalability in web applications and real-time web applications. Because of this, it has a wider acceptance amongst the developer’s community.
Various Corporates like Netflix, Microsoft, Wal-Mart, Yahoo have started using Node js because of its diverse scalability and lightning-fast speed. The best way of utilizing Node.js in the corporate world is by hiring Node js Developer so that he can ensure everything is working smoothly.
This tutorial demonstrates some of the significant Node.js development tips and best practices because of which you can improve your Node.js skills-
Today’s web applications face a lot of difficulties like the performance problem, error handling problem, structure problem, confusion among developers due to a large number of code lines. There are approximately 1500-3000 code lines, even in a small project. Handling large programs has become one of the most prominent problems of developers. To tackle these problem computer scientists began to organize the code into smaller pieces. This is the concept of Modularization. It is used in Node.js to make

Lack of development style sets can lead to severe complications in the code. This is avoided by opting for Javascript Standard Style. As Node.js is a Javascript itself, the same language can be used on the backend and frontend. This helps in breaking down the boundaries between front- and back-end developments. Using Javascript Standard Style also reduces unnecessary complications in managing the code.
Traditionally, input-output operations used to happen synchronously. This means that the main thread used to be blocked until the file is being read, nothing could be done in the meantime. The blocking of main thread for multiple operations affects the CPU utilization and the overall performance of web application adversely.
To solve performance problem and to utilize your CPU better, Node.js introduced an asynchronous programming model. In this resources aren’t blocked instead all tasks are performed simultaneously. Asynchronous processing is a form of input/output processing where all the tasks continue to work in parallel order thereby making proper use of CPU. The Promise object and the Event Loop are proved to be of immensely helpful in Asynchronous programming. The event loop acts as the heart of Node.js and does the work of scheduling asynchronous operations.
Semantic Versioning (referred to, as SemVer), is a versioning system that’s been mostly used in past some years. Updating packages without semVer can lead to major issues. Therefore the use of Semantic Versioning to notify customers about updates is important. SemVer does the work of jolting the accurate component up at the exact time.
Require statements work synchronously, and if they are not together they can slow or stop the execution. Hence, it is always recommended to group “the require” statements and put them at the start. This way issues of performance and slow processing can be avoided

Presence of any kind of bug in the program causes a lot of glitches during processing and executing the program. It can make program useless or may lead to many worse scenarios. For large programs, it was always difficult to detect the problem than to tackle it.
Because of the Modularization, it has become easier to detect the errors and bugs at an early stage thereby reducing the chances of ugly scenarios and increasing the efficiency of the code. Handling of error has become easier in Node.js.

Node.js has achieved a lot of popularity because of it's easy to use, fast performing features and diverse scalability. With popularity comes the risk of attack. While working with Node.js, the developer plays with a huge amount of sensitive user data. Hence security has to be the first priority.
Node.js and its core contributors uphold various different means and sources to provide the required security to the Node.js project and to provide security to the user’s data. There are various applications and tools within Node.js to take care of Brute force attack, Data validation, project security, Session Management.
The rate of these tools and applications is much more effective, therefore many developers prefer the Node.js security mediums.
Hire a Node.js developer or do it yourself, the above-mentioned features and techniques supported by Node.js should always be implemented properly to improve your Node JS performance for the smooth working of code, effective error handling and fast debug free processing.
