Please put all issues regarding IPFS design in the ipfs repo issues.

Please put all issues regarding node IPFS implementation in this repo.

Install

WARNING: this does nothing useful yet!

git clone https://github.com/jbenet/node-ipfs
cd node-ipfs
make
ipfs

The Makefile basically does:

# npm install all deps
cd submodules && ./npm-install.sh && cd ..

# link cli
cd submodules/ipfs-cli && npm link

Example

Suppose we have some files

> tree foo
foo
├── bam
│   └── bam
├── bar
└── baz

1 directory, 3 files

> cat foo/bar foo/baz foo/bam/bam
bar
baz
bam

Let's add them to ipfs

> ipfs add foo
foo: ignored (use -r for recursive)

> ipfs add -r foo
foo/baz: added block /XLM1ZETht3wv8vUPXMkx3JZGP5T9txAz782
foo/bar: added block /XLMCA8WXBNRBwFhzRnHgHFLwGmQzkAQELH7
foo/bam/bam: added block /XLaGqmCUX7sk52P4pkth8S5wV4NMztnf9zd
foo/bam: added tree /XLMLiUaCc7jh3eGFsNR8AhvRSSFySSvTaNb
foo: added tree /XLaoVHd834v62UsW56jew8Mp6FgZBXnZEeL

This added each file + directiory as block and tree objects, including the hash addresses.

We can list the directories (foo/ and foo/bam)

> ipfs ls /XLaoVHd834v62UsW56jew8Mp6FgZBXnZEeL
XLMLiUaCc7jh3eGFsNR8AhvRSSFySSvTaNb 47 bam
XLMCA8WXBNRBwFhzRnHgHFLwGmQzkAQELH7 6 bar
XLM1ZETht3wv8vUPXMkx3JZGP5T9txAz782 6 baz

> ipfs ls XLMLiUaCc7jh3eGFsNR8AhvRSSFySSvTaNb
XLaGqmCUX7sk52P4pkth8S5wV4NMztnf9zd 6 bam

We can cat the files.

> ipfs cat XLaGqmCUX7sk52P4pkth8S5wV4NMztnf9zd
bam

> ipfs cat XLMCA8WXBNRBwFhzRnHgHFLwGmQzkAQELH7
bar

And we can resolve paths through the trees :)

> ipfs cat /XLaoVHd834v62UsW56jew8Mp6FgZBXnZEeL/bar
bar

> ipfs cat /XLaoVHd834v62UsW56jew8Mp6FgZBXnZEeL/bam/bam
bam

> ipfs refs -r /XLaoVHd834v62UsW56jew8Mp6FgZBXnZEeL
