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)

const _7z = require('7zip-min-electron');

// unpack
_7z.unpack('path/to/archive.7z', 'where/to/unpack', err => {
    // done

// unpack into the current directory (process.cwd()) if no output directory specified
_7z.unpack('path/to/archive.7z', err => {
    // done

// pack
_7z.pack('path/to/dir/or/file', 'path/to/archive.7z', err => {
    // done

// list
_7z.list('path/to/archive.7z', (err, result) => {
    // in result you will have an array with info list for your archive
    // for each element in archive you will have:
    // name, date, time, attr, size (in bytes), compressed (compressed size in bytes), crc, method, encrtypted, block
    // depeneds on archive type some values may be empty or missed

// cmd
// in the first parameter you have to provide array of parameters
// check 7z's Command Line Version User's Guide - https://sevenzip.osdn.jp/chm/cmdline/index.htm
// 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
_7z.cmd(['a', 'path/to/archive.7z', 'path/to/dir/or/file'], err => {
    // done
