Option to rewrite all urls to /index.html

[peterpeterparker]

Context

Juno is expecting developers to use SSG / prerendering. For example, if an URL /marketplace/sales is requested and if there is no /marketplace/sales/index.html or /marketplace/sales.html available in the dapp, nothing is resolved and the URL ends in error.

Solution

Similar to Firebase, we can add an option "Configure as a single-page app (rewrite all urls to /index.html)?"

When set to true, if an URL /marketplace/sales would resolve no asset, then it should fallback to the root ./index.html.

Firebase

Firebase does more than "just" rewriting to ./index.html it also provide a configurable way to provide multiple rewrites.
