This is a most excellent place for technology news and articles.
As a point of comparison, in the last place I worked, the main project had over 600MB of javascript dependencies it pulled from node. Plus 300MB of python libraries for Django and whatever else.
At my current job, preparing your environment for development of one "isolated" php system will need at least 3GB of dependencies. Even the main programmer behind it has no clue how it happened or why.
