Description

Originally recorded during the Berlin Developers Meetings from July 9-13, 2018.

A

Like in preparation for so we're kind of rebuilding the web at the moment and in preparation for doing it said for doing that, I thought it might be a good idea to explore what what an IP LD and just try and get it done in the CLI first. And so you can npm install', IP, LD explorer and then type it in on your m in your command line and explore your explore the IP, LD or nodes in your in your ipfs repo and so by default. If I type LS, then.

A

So I, by default- it just drops me in at a a hash that we that we know is local winds there and by default it just gets your NFS root, so I'm at the hash, which is of my current EMFs root, and so you can see here that these are all the files in my m FS root, which is mounted using IVFs fuse me stack, and so we can so we can do stuff like CD, which is changed, dag so I can yeah I can traverse into into like folders and stuff and I can actually because we're changing, dag, not directory I, can traverse into actual files and list out links in them and I've got some autocomplete.

A

So we can resolve and it gives it tells me about about the node that I'm currently looking at like to see ID to size, the data and the links that are in there. So you can see- and so that's my current m FS route, if I, if I then like added something to em FS or a change that if I changed if I rename something like that, then if I CD again I get a different hash because everything's like propagated through and we get, we've got a different root.

A

Node now, but I'm still looking at my NFS and my file name changes.

A

Cool so with these earth, so you've seen that this looks. I said that this is an IPL, the Explorer and we've we're basically looking at protobuf tag nodes at the moment because we're looking for MF s, so what we should do is make some like C ball nodes or something and then explore them. How do we feel so? I can.

A

Let's echo a so if I create a node, let's say just testing testing.

A

Yes, good I get it I get some hash, which is good.

A

So CD CD into their resolve is to see what diagnosis got something in it. That's right, I can also cause I, can say CD into test and then resolve that that's the data is a string thing which is cool, but then we can do more interesting. Stuff is to do like create a dag note that links to that diagnose.

A

I'm gonna use the traditional program thingies and so a link see a link and IP OD pink in JSON format. Oh.

A

So we can have like some link data in our seaboard. Node and I can also have some like data data, which could be like.

A

I prepared this.

A

A

Where did that h come from? Oh, no thanks! I need you to be my linter.

A

Okay, so now we've got now: we've got a new node which hopefully links to that other node that I created. So if I switch back to that and change dag into that node and resolve it, so look great so I've got this. Foo is another Seaborn ID, oh wait! No, we should put a dag PB node in it right. So if I just take one of these okay, let's do that because then I can traverse through, like others. So this is I'm gonna put in a PB which is a link to a PB node.

A

And then so now, we've got two links which one of them is a probe of stagnating one under the sea wall diagnose one of them is actual data, that's a better view of it and then we should be able to just reverse into it. So if I CD into food, then I'm here and yeah.

A

A

One's a PB.

A

Cool and that's basically it you can just mess around of it- explore explore your DAGs in UCLA and and have some fun.
