jntar is a JavaScript tar (meta)Archiver implementation. To be more precise jntar is a proof of concept to ilustrate the benefit of meta-compression.
Beware this is experimental code
As such the API is subject to change and the code quality is...ahem...Let's talk about it when version 1.0.0 will be released.
# Recommended if you want to use CLI tool
sudo npm install -g jntar
# If you only want to use it in your code
npm install --save jntarAs a CLI tool :
# Compression
jntar c jntar.tgz targetdir1
# Decompression
jntar d jntar.tgz uncompressdirAs a JavaScript module
// Compresion
const jntar = new JnTar('jntar_archive.tgz');
jntar.compress(['dir1', 'dir2'], callback);
// Decompresion
const jntar = new JnTar('jntar_archive.tgz');
jntar.decompress('uncompress_dir', callback);The constructor take only one parameter the archive name
Example:
const jntar = new JnTar('jntar_archive.tgz');Asynchronously archive all the directories in the array passed as first arg.
The callback cb will be called when the compression is done.
Asynchronously decompress the archive to the dir passed as first arg.
The callback cb will be called when the decompression is done.
Q: Does it works ?
A: I archived a file tree (1.9G) with tar (czvf) and jntar look at the results
arnaud@vm03:~/jaguar_archiver_playground$ du -sh *
236M jntar.tgz <---------------- Seems it works !
406M tar.tgz>
Q: Why this name, jntar ?
A: jntar stands for Jaguar Network TAR
(As I'm fortunate enough to work in a company (http://www.jaguar-network.com) which allows me to work on Open Source projects)
But if you prefer let's just pretend it means: JavaScript Neo TAR
Q: Why another file dedup tool ?
A: It's not only a file dedup tool.
For me it's: a proof of concept, a meta-compression playground, (soon) the best archive tool in the world ;-)
Q: Why don't you <put your idea/feature here> ?
A: Feel free to submit patch :-)
