📚 Description

This works locally, I tested it against https://github.com/Hebilicious/authjs-nuxt/ which previously needed

      "jose": resolve(__dirname, "../node_modules/jose/dist/browser/index.js"),
      "@panva/hkdf": resolve(__dirname, "../node_modules/@panva/hkdf/dist/web/index.js"),

And now it works 🎉

Rather than hard coding details about presets in the rollup config, perhaps we could have the export conditions set in the options and specifically in each preset?

That would also make it possible for users to configure this, and keep the core rollup configuration generic.

@pi0 Regarding nitro.options.dev ? "development" : "production", if I'm not mistaken, this should always be production, except for the "nitro-dev" preset right ? If that's the case I think @danielroe refactor suggestion that implemented in 5194cc7 make things tidy as we can have a static exportConditions for each preset
