QSS: Update Quiet client to detect a v2 invite link format

[leblowl]

When joining, when a user enters an invite link, Quiet should be able to detect the new invite link format, and if it’s a v2 invite link, then call DOWNLOAD_INVITE_DATA before continuing with the flow.

Mobile launches the deepLink saga on start. We can update deepLinkSaga to detect the invite link type and if it’s a v2 type, call DOWNLOAD_INVITE_DATA and then dispatch the createNetwork action with the returned invite data just like the deepLinkSaga already does.

Desktop deals with parsing the invite data in main.ts and then calls customProtocolSaga. We can simplify things by refactoring customProtocolSaga to act more like mobile’s deepLinkSaga and contain the invite parsing code. In customProtocolSaga, we can also detect if we receive a v2 type link and call DOWNLOAD_INVITE_DATA and then dispatch createNetwork action with the returned invite data.

I'm missing the clear definition of "v2 invite link".

Based on that information - https://docs.google.com/document/d/1dWWwthyJAoNl6sRT5oBGFnuNnYJiU8ZEn7W5Cm1zPRI/edit#heading=h.g05xbtyae2g I would assume that the format looks like that:

https://tryquiet.org/join/?s=<server_url>&CID=<cid>&i=<inviterAadress> or <peerId><someConnector><onionAddress>

So example invitation url would be:

https://tryquiet.org/join/?s=https://tryquiet.org/api/invite/&CID=QmdfTbBqBPQ7VNxZEYEj14VmRuZBkqFbiwReogJgS1zR1n&i=Qmf3ySkYqLET9xtAtDzvAr5Pp3egK1H3C5iJAZm1SpLEp6-y7yczmugl2tekami7sbdz5pfaemvx7bahwthrdvcbzw5vex2crsr26qd

or (if inviter address is just onion address):

https://tryquiet.org/join/?s=https://tryquiet.org/api/invite/&CID=QmdfTbBqBPQ7VNxZEYEj14VmRuZBkqFbiwReogJgS1zR1n&i=y7yczmugl2tekami7sbdz5pfaemvx7bahwthrdvcbzw5vex2crsr26qd

@leblowl could you confirm?

I think we decided that in first iterations <server_url> will be hardcoded (pointing to our server). I'd also make it customizable for devs so they can use relay server on localhost.

[leblowl]

I might start with something like: https://tryquiet.org/join#c=<cid>&t=<token>&i=<inviter_onion_address> The api.tryquiet.org/invite part can be hard-coded, so I don't think we need a s=<server_url> part yet. But it might also be good to check if we meet linkify (length) requirements even with an s=<server_url> part and i=<inviter_address>. I think we probably do, but would be interesting to see how much space we have left in the link.

[holmesworcester]

One nice thing about having s=<server_url> is that we won't need to change the link in the future when someone wants to run their own server.

[EmiM]

Yeah, I was thinking to add this now if it's low cost and not worry about adjusting invitation link format later
