PKGER is web layer over rollup that outputs esm bundles for packages
The project page has more detailed information about what it is, what it can do, and how to use it.
I made PKGER a little while ago with the primary goal of making full rollup bundles online easy.
Using pika.dev’s package cdn and unpkg as a reference.
A secondary goal was to create a moderately complex server/program that was well documented to learn from.
The code is (hopefully) well documented and commented, although there are parts where it is lacking.
What the code does is download packages with pnpm’s internal modules that it uses, and rollup to bundle the code, and restana as a lightweight and speedy server to handle requests.
