By default, "." entry added

When running on Linux system the pack example tar.pack('./my-directory').pipe(fs.createWriteStream('my-tarball.tar')), the generated tar contains a “.” entry.

tar -tf my-tarball.tar . my-file.txt another-file.txt

This entry should not be included.

Thanks for the workaround @Chcap! 😃 For anyone looking for a quick solution, my code now looks something like this:

const fs = require('fs');
const { promisify } = require('util'); /* Note that this requires Node.js 8+ */
const tar = require('tar-fs');

const readdir = promisify(fs.readdir);

/* ... */

const entries = await readdir('/path/to/dir');
const tarStream = tar.pack('/path/to/dir', { entries });

/* Stream tarStream to somewhere, e.g. to a file:
 * tarStream.pipe(fs.createWriteStream('file.tar')); */

Note also that the await syntax requires this code to run inside an async function rather than at the top-level of a module. You can achieve this just by encapsulating it in a function and executing that function, e.g.:

async function packTar() {
    const entries = await readdir('/path/to/dir');
    const tarStream = tar.pack('/path/to/dir', { entries });

    /* ... */
}

packTar();

No, not breaking, but it can be confusing for a user when finding a tar file with these strange “.” entry. I agree, it is a minor issue 😃

The workaround I used is to tar parent directory and to use my target directory as unique entry.

A solution would be, if no entries provided, to populate the queue with the list of files from readdir instead of single entry “.”.
