about

vite-plugin-cdn refers to esm.sh by default, but it can also refer to cdn such as skypack.

export default defineConfig({
  plugins: [
    cdn({
      // :name, :version, and :path are variable items.
      format: "https://cdn.skypack.dev/:name@:version/:path"
    })
  ],
});

The pattern can also specify a function.

export default defineConfig({
  plugins: [
    cdn({
      format(name: string, version: string, path?: string) {
        return name == "react"
          ? `https://esm.sh/preact@${version}/${path ?? ""}`
          : `https://cdn.skypack.dev/${name}@${version}/${path ?? ""}`;
      }
    })
  ],
});

You can explicitly select or exclude packages to be loaded from cdn.

export default defineConfig({
  plugins: [
    cdn({
      // By default, all packages are loaded from cdn.
      includes: [ <package-name>, ... ]
    })
  ],
});

// or

export default defineConfig({
  plugins: [
    cdn({
      // Packages specified here are not loaded from cdn,
      // but are bundled by vite in many cases.
      excludes: [ <package-name>, ... ]
    })
  ],
});
