Modern Web Application - Design : <p>I am building a large web application in node.js and I'm always faced with the question 'where should the heavy lifting be done?' I was always taught that the 'logic' should always be done in the backend of the application, but with modern computers and browsers being so powerful it begs the question if some of the heavy lifting logic can go in the front end. </p>

<p>So context to my specific application. Using angularjs and postgres. A specific question is: would it be a bad practice to have the back end api fetch the rows from the database and pass it to the front end. And then have the front end deal with the logic of deriving the information from the rows? Things like counts with in date ranges and such. (ignore security for this question) or should all the be done on the backend? </p>
