JavaScript implementation of the UnixFs importer used by IPFS
npm install ipfs-unixfs-importer
> JavaScript implementation of the UnixFs importer used by IPFS
Let's create a little directory to import:
``console`
> cd /tmp
> mkdir foo
> echo 'hello' > foo/bar
> echo 'world' > foo/quux
And write the importing logic:
`TypeScript
import { importer } from 'ipfs-unixfs-importer'
import { MemoryBlockstore } from 'blockstore-core/memory'
import * as fs from 'node:fs'
// Where the blocks will be stored
const blockstore = new MemoryBlockstore()
// Import path /tmp/foo/
const source = [{
path: '/tmp/foo/bar',
content: fs.createReadStream('/tmp/foo/bar')
}, {
path: '/tmp/foo/quxx',
content: fs.createReadStream('/tmp/foo/quux')
}]
for await (const entry of importer(source, blockstore)) {
console.info(entry)
}
`
When run, metadata about DAGNodes in the created tree is printed until the root:
`

}
`console`
