ipfs-only-hash/cli.js

Just enough code to calculate the IPFS hash for some data

    # get the cid v1 for the file

    $ echo "hello world" | ipfs-only-hash --cid-version 0
`, {
  flags: {
    cidVersion: {
      type: 'number',
      default: 1
    }
  }
})

async function main (cli) {
  let stream = process.stdin

    stream = fs.createReadStream(cli.input[0])
  }
  const hash = await Hash.of(stream, { cidVersion: cli.flags.cidVersion })
  console.log(hash)
}

main(cli)
