[alanshaw]

• Version: 0.27.3
• Platform: macOS 10.13.1
• Subsystem: files

Type:

Bug

Severity:

High

Description:

ipfs cat on a directory displays the contents of a file in a sub directory, not the error "this dag node is a directory"

Steps to reproduce the error:

$ jsipfs init
initializing ipfs node at /Users/alan/.jsipfs
generating 2048-bit RSA keypair...done
peer identity: QmU8eJXWVYudzSrV5fxQuptmK1haqMG6E1eKP47xuF4e1K
to get started, enter:

	 jsipfs files cat /ipfs/QmfGBRT6BbWJd7yUc2uYdaUZJBbnEFvTqehPFoSMQ6wgdr/readme

lets cat that directory:

$ jsipfs cat QmfGBRT6BbWJd7yUc2uYdaUZJBbnEFvTqehPFoSMQ6wgdr

This is an issue on js-ipfs-unixfs-engine. @pgte is this something you could take a look? Also, let's make sure to add a test to interface-ipfs-core.

[pgte]

On it.

@alanshaw test out js-ipfs 0.27.4 and let me know how it goes :)

I'm getting Uncaught TypeError: Cannot read property ‘content’ of undefined when ipfs.files.cat on a directory now.

This is the hash I'm trying, which should be available in all IPFS repos:

ipfs cat /ipfs/QmeZZkwN*zNgz38RBhHxmbCLH8UoUGQ*****6fcERe
Error: this dag node is a directory

Can someone tell me how to solve this issue?

let file = fs.readFileSync(path);
let varr = { path: path, content: file };
let fileAdded = await ipfs.add(varr);
let fileHash = fileAdded.cid;
