This only exposes extract and pack.
You can pack() a directory and pipe it as stream.
You can pipe a stream into tar.extract().
So it just uses tar-stream. But what about direct access to the tar stream?
When you pack, it accepts a bunch of callbacks.
And it uses the fs, but we want it to accept a fs parameter, preferably with VirtualFS.
So it can be isolated, and if we can have direct access to the tar-stream too.
ignore
The pack takes cwd and opts.
Oh it takes the fs parameter. Cool. So it's just xfs = opts.fs || fs. So if we pass it a virtualfs. Then we can just create it there then!
Wait... it's still using fs... Oh...
Ok so all we need to do is ignore fs.
var vfs = require('virtualfs');
var tar = require('./index.js');
var fs = new vfs.VirtualFS;
fs.mkdirSync('/dir');
fs.writeFileSync('/dir/a', 'abc');
tar.pack('/dir', {
fs: fs
});
Ok so this works. We just need to pass our vfs into it.
And everything else is fine.
