boggan / unrar.js Goto Github PK

Hi, how I can use streams? My file size 50gb and I haven't a lot of RAM

Windows user here and apologizes for my offensive word usage.

Already overwhelmed by the libraries out there, it's damn hard to get a single one worked. The closest working one I came across is that Chinese made Library (Shit can't write files, only read list - good one anyway) and the rest including yours are not working.

I love your library as it implemented in pure JS rather a wrapper around unrar binary

However, my heart got broken when I ran my first code using your lib. The thing output following,

unpackedFiles.forEach(function(file){
              ^
TypeError: Cannot read property 'forEach' of undefined

My code is similar to your sync example!

As async usage gives me an error on extract (issue #2), i want to try to extract using sync method.
the problem is i can not save extracted files on disk, and set output directory.
I tried to save file.data using streamWriter for each unpacked files. but could not make it work.
is it possible to automate extraction by setting output path like you do in async method?

Trying to async extract a rar file, after finishing the process, this error shows and some of extracted files are broken.

`const unrar = require('unrar.js');
const fs = require('fs');

let unpackedFiles;

let rarFile = '/media/creatxr/DATAL/xxx.rar';

unpackedFiles = unrar.unrarSync(rarFile, {
onProgress: function(data) {
console.log(data);
let l_nPercent = Math.round((data.currentBytesUnarchived / data.totalUncompressedBytesInArchive) * 100);
console.log("Progress: ", l_nPercent, "%");
}
});

unpackedFiles.forEach(function(file){
console.log(file.filename, file.fileData.length);
});`
