A pinch of IPNS, some chunking of files and you'll have a delicious IPFS stew for supper.

Better head over to your nearest modules'R'us store because #JS #IPFS 0.32 has hit the shelves. We got #IPNS, custom chunking & loads more goodies. Enjoy 🍦! P.S. more info here: https://t.co/sU0GorC0l7 … #libp2p #fingerprinting #rabin pic.twitter.com/PcPXS8fVMl

🔦 Highlights

📛 IPNS locally

IPNS has it's foot in the door, and it's coming in! In this release IPNS works for your local node. It means you can now publish records to your local repo and read them back. There's still some way to go but you know the saying right, "from small beginnings comes great IPNS"?

🕵️‍♀️ Partial ipfs.resolve

In preparation for IPNS landing, we've rolled out a partial implementation of the resolve command. The idea of the resolve command is to figure out the underlying hash of the content referred to by an IPNS name or an IPFS path.

The new resolve command can resolve paths like /ipfs/QmRootHash/path/to/file to /ipfs/QmFileHash and will soon be able to deal with IPNS names in an upcoming release.

📦 libp2p bundle function

We made it even easier to create your libp2p bundle! If you're looking to create a completely custom libp2p bundle then you can now pass a function in place of your libp2p config which should return your libp2p bundle. It's passed useful information like the IPFS node peer ID so you should be able to build your bundle exactly the way you want! You're welcome 😁

🥒 Support for chunking algorithm

Slice and dice your DAG nodes the way you want™️. When adding data to your IPFS node you can now specify the size of the chunks it creates from your data or even use rabin fingerprinting to create some fancy variable length chunks for better deduping.

Rabin is a native module and must be compiled on your system when you run npm install ipfs. Native modules depend on specific languages and tools to be pre-installed on your computer and because of this has been made an optional dependency. That means that it's 👌 if it fails to install, it just won't be available to use in IPFS. If you're thinking of using rabin chunking then be sure to check that it installed properly in your install logs.

Check out the docs for the files.add chunker option for more.

🏗 API Changes

• Added ipfs.name.publish and ipfs.name.resolve. This only works on your local node for the moment until the DHT lands. API docs can be found here.
• Added ipfs.resolve API. Note that this is a partial implementation allowing you to resolve IPFS paths like /ipfs/QmRootHash/path/to/file to /ipfs/QmFileHash. It does not support IPNS yet.
• ipfs.files.add* now supports a chunker option, see the API docs for details
