side-channel native replacement

[justinfagnani]

side-channel can be replaced by a WeakMap - I think.

There aren't any docs, so I'm a bit confused how this package has 1400 dependents. How do they know what they're using? It seems like the vast majority of dependents are create-next-app packages that don't directly depend on this in their source, but do in the published package. SO that must be something about create-next-app or Next.js's build system.

But the usages I did see mostly look like they could easily be replaced by a WeakMap. The side-channel tests do have some other APIs, like assert(), but those can probably be one-liners as well.

It has a pretty large dependency tree: https://deptree.rschristian.dev/?q=side-channel
