Implementing Helia

Help Helia

Super Excited for this to reduce dependency on gateways to communicate to nodes via the browser.

I have a couple questions in the implementation. It seems the networking example is set up using tcp which doesn’t work for in browser. I found an example in the libp2p library on how to setup web transports but it is seemingly outdated since connectionManager is no longer existing. See here for reference: js-libp2p/index.js at master · libp2p/js-libp2p · GitHub

Also it results in alot of peers being found but being unable to dial to it.

Still abit new to this but is there a example project that shows helia connecting to a kubo node via webTransport and what is required to properly configure the libp2p? Just trying to be able to run cat on a CID and direct connect to a node that I know has the data I need. Currently at IPFS thing as well.

We just made this: GitHub - libp2p/universal-connectivity

Does the repo help you? If you need any help getting it up-and-running let me know.

A little bit! will have to dive more into it

Hi,
Did you find a way to setup libp2p with web transport? I am trying but I don,t understand, could you share your solution? Thanks a lot

FYI: the libp2p setup for Helia is fairly straightforward:

but most of that comes from Helia’s default libp2p config for the browser: https://github.com/ipfs/helia/blob/main/packages/helia/src/utils/libp2p-defaults.browser.ts

As far as configuring Kubo to announce webtransport addresses, I believe any issues there have been fixed since I last updated my IPFS config, but here’s my config if it helps:

Note that webtransport does not seem to be listening publicly (for Kubo) unless I set my public IP address in Addresses.AppendAnnounce manually. I thought this to have been resolved with fix: fix externally defined webtransport addresses by aschmahmann · Pull Request #2224 · libp2p/go-libp2p · GitHub, but it doesn’t appear to be resolved. When I remove my public IP from AppendAnnounce, my listening Multiaddrs do not list anything except private IPs: 127.0.0.1, 192.168.1.227, ::1, etc…
