⚡️ v0.37.0 RELEASE 🚀 #2192

Closed alanshaw closed 5 years ago

New constructor, better DNSLink support and delegated routing!

🗺 What's left for release

🔦 Highlights

👷‍♂️ Brand new constructor

We're in the middle of converting IPFS, libp2p and IPLD modules to using async/await and async iterators instead of callbacks. This will eventually bubble up to the JS IPFS programmatic API where there will likely be some changes that will effect your application. To ease the transition when that happens we're encouraging new and existing developers away from using our callback based APIs, towards Promise based APIs. You'll see the change reflected in our API docs soon. For now, there's no breaking changes, all existing APIs continue to work as usual with callbacks.

In this release there's a new way to construct an IPFS node using promises:

const IPFS = require('ipfs')
const node = await IPFS.create()
// Done, ready to use!

All the usual options you'd normally pass to the constructor can be passed to create. Did we mention that it's completely backwards compatible? Well yeah, it is. No breaking changes here 😜 - you can still use new IPFS() and wait for the ready event as you used to. Or, alternatively, you can still use the constructor and await on the new "ready" promise like so:

const IPFS = require('ipfs')
const node = new IPFS()
await node.ready
// Done, ready to use!

More details in the IPFS constructor docs.

🌎 Support for DNSLink IPNS name resolution

JS IPFS can finally resolve a DNSLink IPNS path. It means that jsipfs name resolve /ipns/ipfs.io will now query DNS for a dnslink TXT record and return /ipfs/QmRq5rhjnfFHYFYbYXoqPpcJQHKu3SUuHADzSzX9ECN5eM (for example).

It also works recursively, so your DNSLink TXT record could return another IPNS path to resolve and it would keep going. Turtles all the way down 🐢. Cowabunga!

Bonus 🎁 this also works on the gateway so http://127.0.0.1:8080/ipns/ipfs.io will resolve and display the ipfs.io website. Hooray 😁!

🧭 Delegated peer and content routing

JS IPFS now supports delegating peer and content routing to another node on the network.

What does that mean though? Well, when you delegate, you get someone else to do something. In delegated peer and content routing we get a different IPFS node to find a piece of content or another peer on the network.

Delegation allows JS IPFS to make use of the routing abilities of other nodes. Typically we delegate to IPFS nodes that have unrestricted access to a DHT. This is useful for IPFS nodes running in the browser, or even for nodes running in resource constrained environments.

IPFS nodes running in Node.js that are behind NATs or that are not running a DHT will also benefit from leveraging delegate routers. If you are running a DHT, the delegate will be used as a fallback router.

We've setup 2 delegate nodes you can use for development and testing, check the docs for configuring delegate routers in JS IPFS and the libp2p delegated routing example for even more info!

✨ Web UI with revamped Files & Peers

The Web UI got a whole new lease of life in version 2.5!

We've introduced a help system designed for new users, with explanations for each section.

The Peers page now allows you to connect to a specific peer via 'Add Connection'. We also have a revamped peers table with sorting, identicons for each peer, a simplified location, a new protocol & transport column and latency!

On the Files side, you can now look at any files in the wild. But what does that mean? You can now see your pins, remove pins, add new pins, navigate to any /ipfs/QmHash or /ipns/domain.com path and explore the IPFS world like you never did before.

If we also want to include delegated peer/content routing, see my notes in https://github.com/ipfs/js-ipfs/issues/2155#issuecomment-504942553

Would be cool if we include https://github.com/ipfs/js-ipfs/pull/2217, as it makes gateway URLs prettier and in line with what go-ipfs does. (Makes /ipns/ feature more polished)

There's a new RC for trying out npm i ipfs@0.37.0-rc.0 🤠
