Description

My production build is a bit heavy:

              Chunk Names
                 static/fonts/element-icons.6f0a763.ttf      11 kB          [emitted]
               static/js/vendor.dd83b1b8e4fd1abaaa41.js    3.19 MB       0  [emitted]  [big]  vendor

What's the best way to tell which 3rd party packages are contributing to this heft?

Research direction
Use webpack bundle analyzer to visualize the vendor chunk's composition. Alternatively, examine the webpack configuration for large dependencies or code splitting opportunities. Review existing comments for additional tools and approaches.
