Usage

The mode of using the program is via CLI. Some flavour or Linux environment is recommended as it it tested on similar environment. But Windows should work fine as well. To run the program, you need to fulfil the prerequisites:

node >= 10.x.x. Checkout this link
npm >= 6.x.x. THe previous command should already install npm. Checkout NodeJS docs or forum for troubleshooting.
yarn >= 1.15.x This project has made use of yarn rather than npm. So you can install yarn by using npm i -g yarn. But nevertheless npm will also work. Only drawback is that, package-lock.json is not included in the repository, so the packages version installed may not quite match with those installed on the developer workdirectory.

Check your environment using node -v && npm -v. This assumes that you have node and npm executable in you OS PATH.

Then assuming that you have cloned the repository, do the following, from project root:

If you yarn installed then run yarn install. Otherwise if you have npm then run npm install.
node ./bin/index.js and follow the prompt
