fix: local and public gateway links when cannot preview

[hacdias]

Fixes #1767 by implementing the suggested solution: link to both local gateway and to ipfs.io.

Please note that availableGatewayUrl can be either the local gateway or ipfs.io and that is still used for all other types.

I could not reproduce #1767 since my computer always got the correct local gateway URL as the available gateway. To show both links, we hard code the ipfs.io link and fetch the actual localGatewayUrl from settings.

This PR superseeds #1826.

Looks good, but we should remove hardcoded ipfs.io and enable users to use gateways of their choosing.

1. rename "with ipfs.io" to "public gateway"
2. hide "local gateway" if it is same as public one
3. make public gateway customizable
   • add "Public Gateway" section to "Settings" screen (you can reuse "API" section for look and feel)
   • it should read value from window.localStorage.get('ipfsPublicGateway') and if missing fallback to showing https://dweb.link
   • replace ipfs.io hardcoded in the app with value from window.localStorage (with fallback to https://dweb.link)

If Public Gateway === Available Gateway (local)

Otherwise

Public Gateway Setting

If bad http url

If empty

Default: https://dweb.link

Looks sweet!

I'm excited for this one – we will leverage the window.localStorage trick in brave and ipfs-companion, to ensure webui uses gateway user set in respective GUI 😻

Needs review

• Confirm with native speaker that labels look ok
  • (cc @autonome mind quickly eyeballing changes in https://github.com/ipfs/ipfs-webui/pull/1834/files → public/locales/en/* ? preview in screenshots in comment above)

Needs fixing:

• Opening non-unixfs DAG like http://localhost:3000/#/ipfs/baf4bcfg4ep767tjp5lxyanx5urpjjgx5q2volvy produces malformed message:

  

• Share link should use gateway set on Settings, instead of hardcoded ipfs.io:

@lidel both fixed. The first point "Opening non-unixfs DAG like" is translation related (see e12efec). I only updated for English as I'm assuming everything else needs to go through Transifex.

Thank you!

Tweaked UI a bit so buttons are active only when they actually do something:

Merging + waiting with release till Friday for new labels to appear on Transifex.

FYSA filled follow-up issues:

• Settings: validate public gateway before saving it Settings: validate public gateway before saving it #1844
• Set ipfsPublicGateway and ipfsApi when opening webui Set ipfsPublicGateway and ipfsApi when opening webui ipfs-companion#1022
