PhantomJS is used to emulate browsers through command line, for generating PDFs, web page manipulation, headless testing and much more interesting stuff. Npm provides us a module called “node-phantom” which helps us to use PhantomJS in our NodeJS application in a non-fussy way. A prerequisite for using this module is, you must have PhantomJS binary […]
Any well written piece of code should be defensive by nature with defensive error handling understanding that things could go wrong. Things would be great if we can define our own custom error classes which we can pass or throw in order to distinguish various errors. Custom error constructors helps in: ⇒ Identifying which error was […]

This helps user to easily navigate through the website as well as faster loading of the web pages. For example, generally we make header and […]
In our node js application, we can use variety of templating engines like “jade” , “ejs”, “mustache” etc. Dust.js is an asynchronous templating engine which can be used both on server side as well as client side and provide easy caching with high performance. In my previous blog on EJS as a templating engine, i […]
In one of our Node.js projects, we used Mongoose module to interact with MongoDB. Mongoose provides us four types of built-in validation on schema as below: 1. Required: We can mark a field as required, which must be provided. 2. Limit: If field is type of Number in Schema, then we can restrict maximum and […]
I was working on one of my projects which involved multiple task execution on regular basis. Well, I think that many of us have faced similar issues on their projects which increases our work and making it more time-consuming and increased work. Working in a community where people are actively developing tools to automate tedious […]
