Back End Developer

Back-end developers are the experts who build and maintain the mechanisms that process data and perform actions on websites. Unlike front-end developers, who control everything you can see on a website, back-end developers are involved in data storage, security, and other server-side functions that you cannot see.

COURSE DESCRIPTION

If you have ever heard about Node.js then you might know that it is one the most prominent and powerful frameworks of JavaScript. Since its release, it has continued to keep its stranglehold on the IT market.

WHAT IS NODE?

Node.js is a powerful framework developed on Chrome’s V8 JavaScript engine that compiles the JavaScript directly into the native machine code. It is a lightweight framework used for creating server-side web applications and extends JavaScript API to offer usual server-side functionalities. It is generally used for large-scale application development, especially for video streaming sites, single page applications, and other web applications. Node.js makes use of an event-driven, non-blocking I/O model which makes it a right pick for the data-intensive real-time applications.

Like any other programming languages, node.js makes use of packages and modules. These are the libraries that contain various functions and are imported from npm (node package manager) into our code and utilised in the programs.

The certification course of back end developers has been designed in such a way that a learner can start from basics and endup with knowing the complete cycle of software development.

Module 7 : Utilities

GIT : From web developers to app developers, Git is useful to anyone who writes code or tracks changes to files. Git is the most commonly used version control system. Git tracks the changes you make to files, so you have a record of what has been done, and you can revert to specific versions should you ever need to. Git also makes collaboration easier, allowing changes by multiple people to all be merged into one source.   So regardless of whether you write code that only you will see, or work as part of a team.

Swagger : Swagger allows you to describe the structure of your APIs so that machines can read them. The ability of APIs to describe their own structure is the root of all awesomeness in Swagger. It can automatically build beautiful and interactive API documentation.

Postman : Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIs—faster.

Clickup : Clickup is a task management tool which removes frustrations, inefficiencies, and disconnects caused by current project management solutions. It helps to organise tasks among the team.
