esm("swr", {
  alias: {
    react: "preact/compat"

// => https://esm.sh/swr?alias=react:preact/compat

buildESMUrl("swr", {
  alias: {
    react: "preact/compat"
  }
});

// => https://esm.sh/swr?alias=react:preact/compat

Resolve typedefs for React from esm.sh

import { buildESMUrl } from "cdn-resolve/esm";

const resolved = buildESMUrl("swr@2.1.1", {
  alias: {
    react: "preact/compat"
  }
});

const typesUrl = await resolveESMTypes(resolved);

// => https://esm.sh/v135/swr@2.1.1/X-YS9yZWFjdDpwcmVhY3QvY29tcGF0/core/dist/index.d.ts

Parse a Package Name
