Built on Chrome’s V8 JavaScript engine, Node.JS is a JavaScript runtime which uses an event-driven and non-blocking I/O model that makes it light, efficient and the largest ecosystem of open source libraries. It is quickly gaining popularity because of the ease of working in it for app developers. More and more app developers are turning towards Node.JS for developing popular apps. Here are some tips to follow to master Node.JS from scratch and become a good Node.JS developer.

Modularize Your Code Node.JS developers organize their code into smaller pieces that improves their readability and modularize it which helps in the development of complex applications in Node.JS while making the most of the asynchronous philosophy.

Group ‘Require’ Statements at the Top In order to avoid performance issues, developers place group ‘Require’ statements at the top as this term is synchronous and pauses the execution. Node.JS developers, instead, make use of the built-in model of Node.JS’s loading system which has its own require function for loading modules, existing in separate files.

JavaScript Standard Style Node.JS developers choose to avoid problems and complications of managing .jscsrc or .jshintrc files and set development style by choosing Javascript Standard Style. The advantages of the latter are that it automatically formats code by running ‘standard – 1/2

fix’, which saves time by fixing programming errors and style issues, uses single quotes for strings, and a single space after keywords and functions

Use Asynchronous Code Node.JS developers can perform input/output operations synchronously (blocks the resources for some duration) or asynchronously (resources aren’t blocked allowing tasks to be performed in parallel). This is because when resources get blocked during multiple operations, it affects the overall performance of the web application.

Semantic Versioning Node.JS developers use Semantic Versioning when updating packages as it helps to keep customers notified about updates and what they need to do for updating to the new version.

Nip the Errors in the Bud Node.JS developers pay attention to and listen to error events in order to prevent later chaos. This helps them to identify errors quickly and take the necessary corrective measures, making the entire error handling process easy and stress-free.

Make Use of Containers Node.JS developers use containers to make deployments secure, stimulate production environments, and so on making them essential to programming with Node.JS.

Ensure Security Security is becoming a paramount expectation in app development. Node.JS developers meet this expectation with the help of numerous applications within Node.JS such as Node.js security, Data Validation, Session Management, Brute Force protection, and so on.

With the Node.JS technology proving itself to be a successful instrument for solving numerous problems, Node.JS developers are gaining preference over other developers. Becoming proficient in Node.JS is becoming essential for them with each passing day. With the help of some of the hints described above, it will be possible for Node.JS developers to master Node.Js.
