How do you develop this plugin locally?

Question

I'm mostly wondering how to start rollup in watch mode.

As is, with a normal build, I get this error:

❯ pnpm build

> [email protected] build <repo>
> pnpm run prebuild && pnpm run rollup


> [email protected] prebuild <repo>
> pnpm run clean


> [email protected] clean <repo>
> rimraf dist


> [email protected] rollup <repo>
> ts-node --esm rollup.config.ts

I'm mostly wanting to figure out why setting browserslist: false seems to polyfill object spread and object own keys. My hope is that, when using babel + the typescript preset that I could opt out of all polyfilling, and tell consumers of my library to add whatever plugins they need if they're targeting old browsers.

at the moment, browserslist: ['last 1 firefox versions'] has less polyfilling than browserslist: false -- so I was hoping to get to the bottom of why. :upside_down_face:

Thanks!

As for your primary question, try again with Node v18 👍

ah! I only had v16 -- thanks!

As for your primary question

do you happen to know something about this browserslist stuff? :sweat_smile:

Probably duplicate of #189?
