Some other applications I can think of is keeping track of some rates of particular items from some sites on daily basis, visiting some website for views (If you are using google products you might not want to use this as google have set strict policy for this), parsing data from other sites.




So, the main purpose of headless browser

What if you want to customize your REST API or add different methods for it?When building an application, you’ll generally need to implement custom logic to process data and perform other operations before responding to client requests.In Loopback there are 3 ways to do this:
Adding logic to modelsDefining boot scriptsDefining middlewareFor this post I'm explaining about the first one, Adding logic to models. There are 3 types to add custom application logic to model. Remote MethodRemote HookOperation Hook Remote Method :A remote-method is nothing but nodejs function mapped to REST endpoints. You can create remote-method by cli or typing by yourself (click here to know how).  In the previous post, I used memory db. For this one, I'm going to use MongoDB as datasource.

Loopback by Strongloop : Getting started

Loopback is developed by Strongloop and maintained by IBM. The LoopBack framework is a set of Node.js modules that you can use independently or together to quickly build REST APIs. Heart of Loopback is its models. The application interacts to data-source through models. The following diagram illustrates, How loopback works :
Benefits of using Loopback over ExpressLoopback has a steep learning curve, on other side Express have a very little learning curve. Loopback has built-in Database integration, whilst you need npm package in Express.Loopback has built-in models and authentication, API explorer, built-in ORM/ODM with the juggle and various driver and ACL. On the other side, Express needs separate npm package for all this. Node.Js is widely used for quickly wrapping up projects with REST APIs. You have to choose the framework that best suits you and the project. Installation :Prerequisite : Node.JsAfter making sure that you have Node.js installed, run this command : npm install -g loopba…

Points to keep in mind while developing Email Templates

I have come to know that in frontend development Email Template designing is a kind of headache for those who don't know how to code the HTML perfectly. There are many things to keep in mind if you're designing an Email template, from the basic difference between a static webpage and an email template or how will email service providers render your template.

So, here are the points you must keep in mind:
1. Use Table instead of divMost of the email clients are not supporting the div structure on top of the body, the render engine mishandles your style. Instead of that, you must use the table tag, which should be the first element in the body.  So, dived your classic div structured into rows and columns for the email. For the best-case scenario, use one column UI. 2. Use inline-cssOutlook, Gmail and Yahoo remove your HTML & head tag to resolve the conflict between their own tags. So, if you are using external css or internal css then it will be excluded, to overcome this you m…

FizzBuzz Problem

Hello guys, today I'm discussing about a well-known interview question, asked for logic measurement of a backend developer in many IT company.
fun fact: This is discussed in Stackoverflow's Annual Survey 2019.


Fizz Buzz Problem Problem statement: Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”PS: I'm using javascript to solve this problem
