ux: add configuration toggle for delegated routing #288

Open lidel opened 3 weeks ago

lidel commented 3 weeks ago

IPFS Camp UX improvement suggestion based on discussions with @aschmahmann

Current state

service-worker-gateway sends a lot of requests to https://delegated-routing.dev but (afaik) we don't have direct retrieval yet, so there is no benefit from it

Proposed UX fix

Empty list of deleegated routing endpoints is bad UX, as user needs to know URL of endpoint to enable it
Let's add a toggle that enables/disables use of addresses defined in the routing configuration field
- It should be disabled by default, until we have direct retrieval working

aschmahmann commented 3 weeks ago

@lidel I don't know if that fix is quite enough. If the delegated routing endpoints are being used for IPNS resolution (as opposed to using the trustless gateway endpoints) then we still need them around even if not doing direct retrievals.

We could at the Helia level not turn on the content or peer routing systems though (or potentially use the trustless gateways for IPNS fetch).

lidel commented 3 weeks ago

Yes, the idea here is to have "quality of life" toggle that disables all delegated routing, and only relies on trustless gateways.

You can still do IPNS via trustless gateways alone, but if verified-fetch does not leverage it yet, we can simply error on IPNS errors, informing user they need to enable delegated routing.

This seems like a duplicate of #267.

That's right. Currently, Helia is built in a way that accepts 3 kinds of routers (libp2p, delegatedHTTPRouting, and httpGatewayRouting) and by default includes both delegatedHTTPRouting, and httpGatewayRouting. The problem is that if we remove the delegatedHTTPRouting, there's no way for Helia to Resolve IPNS names.

I've opened https://github.com/ipfs/helia/issues/558 to address this gap in Helia.

Descoping from Camp milestone due to impact on DNSLink (see https://github.com/ipfs/service-worker-gateway/pull/303#pullrequestreview-2148664363).
