css , SASS , Uncategorized / December 15, 2019

Hey, folks! Welcome to the  Sass series. The aim of this series is to give a general idea of what Sass is, why it is beneficial and what are the key properties of Sass which makes it beneficial. Becoming an expert is in Sass can be achieved through rigorous practice and hands-on experience in real projects. This series will give you guys a platform to start with. WHAT YOU WILL LEARN Sass is a CSS preprocessor Sass has two syntaxes Sass syntax allows variables, mixins, nesting rules and properties, function Variables declared using $ , 7 data types are supported,and scope of variable. Interpolation for selector or property names using {} Parent selector using & and nesting     Sass or syntactically awesome stylesheet Sass is a CSS preprocessor that will generate CSS files for your project. “A CSS preprocessor is a program that will generate CSS  from a syntax supported by it.” Sass generates CSS files from .sass or .scss files that have their own syntax. Sass allows using features like variables,functions, mixins, etc that CSS files do not allow(CSS now supports variables but the usage is a bit different and browser support is limited).   SASS is originally written in Ruby. A…

This is the second part of our Sass series, aimed at providing a better understanding of  Sass  @-rules and Directives. Part 1 of the series provided an introduction and taught by example about variables and nesting in Sass.   WHAT YOU WILL LEARN @-rules and Directives 11 Directives @-rules of CSS  CSS provides statements called @rules which are rule statements preceded by an @symbol. Most commonly used @rules are @media,@keyframes,@import, etc Sass extends some of these  @rules and provides other directives as well. “A directive is something that introduces new syntax. Sass directives help in writing CSS in an easy and better way” There are 7 @rules and directives you can use in Sass. They are as follows @import @media @extend @debug @warn @error @at-root @forward @use @mixin and @function       @-Rules and Directives @import directives – @import directive is used to import Sass files (SCSS/SASS) into one another. Using the @import directive while properly modularizing the application can improve code reusability and avoid repeats. Consider two scss files _sectionone.scss _sectiontwo.scss These have styles for two sections and these scss files are called partials.  _ is what sass uses to identify a partial file. These partial files can…

css , SASS , Uncategorized / December 29, 2019

This is the third part of our Sass series aimed at providing insight in o  Sass operators and control directives. Part 1 of the series provided an introduction and taught by example about variables and nesting in Sass.  Part 2 of the series provided a better understanding of @-rules and Directives.   WHAT YOU WILL LEARN Operators and types of operators in Sass. Control directives and types of control directives in Sass. Operators in Sass Expressions are written using operators. There are different types of operators supported by sass and they can be broadly classified into Numeric operators, Relational operators/ Comparison operators, and Boolean operators. Numeric operators: +, – , *,  / ,% are numeric operators. These operators are used to write expressions that perform mathematical operations just like in most programming languages.   +, – and / can be used with values of string data type to perform operations like string concatenation.   +,-,/ are also used as unary operators(operators which require one operand).

TRY IT OUT Relational operators/Comparison operators:    <=, >=, >, <!=, == are  relational operators. These operators are used to write comparison expressions.

  Control Directives Control Directives are directives that are used to create…

Understanding Microservices, Web services, APIs and Endpoints
architecture , Uncategorized / December 4, 2019

Many beginners who start development, especially back end, get confused with terms like APIs, Microservices, Web services, endpoints, etc. The aim of this article is to describe what these terms are with a simple example. Please note that the example given here is just a demo. Microservices Microservice Architecture is a way of designing the structure of an application. Microservices are independently deployable services that together make the application. The architecture of an application can be in such a way that it can have multiple independent microservices that can function together. Splitting the application into microservices makes the maintenance of the application easier. It is also helpful in reducing the complexity of the application. Proper microservice architecture reduces complexity, increases flexibility, increases reusability as compared to a monolithic architecture.       API(Application Programming Interface) According to NIST definition, an API is, A system access point or library function that has a well-defined syntax and is accessible from application programs or user code to provide well-defined functionality. API provides a well-defined set of protocols, routines, and rules for a system so that another system can communicate with it. An API specifies how software components should interact. Documentation on how to…

Understanding Cloud service models IaaS, PaaS and SaaS – Cloud 3
Cloud , Uncategorized / December 3, 2019

You might have heard acronyms like IaaS, PaaS, SaaS, what do they actually mean? what are cloud service models?. This is the third part of the Cloud Series and aims to provide an answer to the above questions. This article will provide you with an overview of cloud service delivery models so that you can choose which service model is best suited for your business application.   Cloud service models Cloud service models are models, based on which pre-packaged combinations of IT resources are delivered to the customer as services, by the cloud service providers(CSP). The three cloud service models following which the services are offered to the customers are Infrastructure as a service(Iaas), Software as a service(Saas), Platform as a service(Paas). Serverless is a cloud service execution model.   Other approaches by which CSPs provide service to the customers are Backend as a Service Backup as a Service Banking as a Service Blockchain as a Service Business Process as a Service Communications as a Service Compliance as a Service Consensus as a Service Container as a Service Crime as a Service Crypto as a Service Data as a Service Database as a Service (DBaaS) Datacenter as a service (DCaaS) Desktop…
