Getting Started With MEAN App Development with AngularJs , ExpressJs , NodeJs and MongoDB.

          Getting Started With MEAN App Development I Started Learning AngularJs one year Back. It is always a nice experience to start learning something new. I used Some of my AngularJs skills in my Programming Calculator App. ( https://nikhilnihal.github.io/programmingcalculator/index.html ) Few Days Back , I Started my hands on NodeJs and ExpressJs. I watched many Youtube Videos and Tutorials of  NodeJs and ExpreesJs. After that , I thought to do a Small Project Using all my skills of AngularJs , NodeJs ,ExpressJs.  I followed a Youtube Video ( https://www.youtube.com/watch?v=kHV7gOHvNdk ) and Made a Small Project Similiar to this one.After that I also Learnt that how to deploy my MEAN app on heroku website( heroku.com ). My app uses MongoDB for database. So , i also used mLab ( https://mlab.com /),which provided me MongoDB hosting service. There is a very useful blog which helped me to learn how to deploy my app on heroku. ( ht...
