Installing dependencies from both npm and GitHub Packages under the same scope? It can get messy. 😖
npm.pkg.heyapi.dev is a drop-in proxy that resolves packages from both sources. Add it to your .npmrc and let it handle those pesky scopes for you.

Give your OpenAPI spec a little massage with v0.78.0 💆
The new parser options allow you to filter, modify, or validate your spec before it’s used by plugins.
The most common transforms are available as a one liner. And they work like magic.
