67% reduction in bundle size when bundling with rollup of instead parcel. Parcel is not tree shaking several classes from @readymade/core FESM, while rollup can. Steps to reproduce a simple example are below. Bug is reproducible on bug/optimize branch.

Steps to reproduce

1. yarn install
2. yarn prod && yarn serve

Observe size of client.js (~23.17 KB)

3. yarn prod:rollup && yarn serve

Observe size of client.js (~7.61 KB)

Project builds in Parcel 1.x fine, but in Parcel 2.0 typescript decorators cause the build to fail.

This project makes hevy use of TypeScript. The Readymade library is dependent on TypeScript decorator pattern.

 🚨 Build failed.
[0] @parcel/transformer-babel: Support for the experimental syntax 'decorators-legacy' isn't currently enabled (7:1):

This error indicates I need to load the @babel/plugin-proposal-decorators plugin in .babelrc, however this dependency was not needed in Parcel 1.x. Adding this dependency opens a whole other can of worms.

"plugins": [
  ["@babel/plugin-proposal-decorators", { "legacy": true }]
]

Steps to reproduce

1. yarn install
2. yarn prod && yarn serve

Curious to know what limitations you encountered with Skate SSR. I'd like to circle back to SSR at some point with lume/element.
