Use a build-helper library instead of DIY

[mmkal]

Possibilities:

• microbundle
  • Pros:
    • Used it before
    • Works well w no config
  • Cons:
    • I don't really need to bundle, just to compile and create a wrapper .mjs file
    • I don't know if it creates wrappers, instead it would create two separate outputs, one for commonjs and one for ESM, which would hit the dual-package hazard. I'm not totally convinced that's a major issue for this library since it just provides helpers for building your own fetch, but probably better to avoid to be safe
    • Doesn't use esbuild or swc (yet)
    • Last publish a year ago (at time of writing, 2023-08-24)
• unbuild
  • Pros:
    • Seems it can build-helpfully rather than bundle
    • Seems easy to configure
    • Last publish 2 days ago
    • Update April 2024: Last publish 8 months ago
  • Cons:
    • Haven't used
    • Marginally less popular than microbundle
• tsup
  • Seen good people use it (trpc, panda)
• just tsc, no -> .cjs conversion
  • The original and still the best
  • Given we don't really need a separate ESM bundle, maybe this is better

tsup looks good, tried it on mmkal/pg-suite

also, no need to create a wrapper mjs file. es modules will still be able to import just fine
