reduce bundle size

[jwkvam]

I don't know if it's possible but the compressed bundle for bowtie-demo is 1.13 MB. Not being an expert I wonder if this is still rather large and if it could be reduced.

       Asset     Size  Chunks                    Chunk Names
   bundle.js  4.17 MB       0  [emitted]  [big]  main
