Usage

You may use pack and unpack methods for simple packing/unpacking.

You can also use list to get an array with the file content properties (includes date, time, attr, size, compressed and name)

Or use cmd to run 7za with custom parameters (see Command Line Version User's Guide)

1const _7z = require('7zip-min');
2
3// unpack
4_7z.unpack('path/to/archive.7z', 'where/to/unpack', err => {
5    // done
6});
7
8// unpack into the current directory (process.cwd()) if no output directory specified
9_7z.unpack('path/to/archive.7z', err => {
10    // done
11});
12
13// pack
14_7z.pack('path/to/dir/or/file', 'path/to/archive.7z', err => {
15    // done
16});
17
18// list
19_7z.list('path/to/archive.7z', (err, result) => {
20    // in result you will have an array with info list for your archive
21    // For each element in the archive you will have:
22    // name, date, time, attr, size (in bytes), compressed (compressed size in bytes), crc, method, encrypted, block
23    // Depending on the archive type some values may be empty or missed
24});
25
26// cmd
27// in the first parameter you have to provide an array of parameters
28// check 7z's Command Line Version User's Guide - https://sevenzip.osdn.jp/chm/cmdline/index.htm
29// the bellow command is equal to `7za a path/to/archive.7z path/to/dir/or/file` and will add `path/to/dir/or/file` to `path/to/archive.7z` archive
30_7z.cmd(['a', 'path/to/archive.7z', 'path/to/dir/or/file'], err => {
31    // done
32});
