Open up your dev tools and play around with the DatArchive API.
Data will be persisted to IndexedDB
Example:
const dateHomepage =
`dat://87ed2e3b160f261a032af03921a3bd09227d0a4cde73466c17114816cae43336`
const archive = new DatArchive(dateHomepage)
archive.readFile('/index.html')
.then((html) => document.body.innerHTML = html)
