Current Behavior

The documentation recommends wagmi/viem as an upgrade path from Ethers.js.

Source: https://wagmi.sh/core/getting-started

Expected Behavior

Provides a working example in this format:

<script src="....min.js" integrity="sha384-HwwvtgBNo3bZJJLYd8oVXjrBZt8cqVSpeBNS5n7C8IVInixGAoxmnlMuBnhbgrkm" crossorigin="anonymous"></script>

import { connect, fetchEnsName } from '@wagmi/core'
import { InjectedConnector } from '@wagmi/core/connectors/injected'
 
const { address } = await connect({
  connector: new InjectedConnector(),
})
const ensName = await fetchEnsName({ address })
</script>

This will be copy-pastable, and will work in all the same places that Ethers.js works. It does not require extra tooling or education. And it supports sub-resource integrity.
