Options to start the server in production and development mode.

tsc :- Transpile typescript to javascript and able to watch and reg-generate the bundle.
ts-node:- Run-time environment that supports typescript under the hood. Has watch mode
ts-node-dev:- extend ts-node with the ability to cache previous compilation to make transpiling faster for every change.
nodemon:- nodemon is a tool that helps develop node.js based applications by automatically restarting the node application when file changes in the directory are detected
node:- convert first from typescript to javascript and then start the node.
