node-7z-archive

node-7z-archive

ESM front-end to 7-Zip, featuring alternative full 7z CLI tool, binaries for Linux, Windows, Mac OSX, seamlessly create 7zip SFX self extracting archives targeting different platforms.

Usage

This library use Promises, it's API is consistent with standard use:

import { fullArchive } from 'node-7z-archive';

fullArchive('myArchive.7z', 'destination', { p: 'myPassword' } /* 7z options/switches */)
// Equivalent to `on('data', function (files) { // ... });`
.progress(function (files) {
  console.log('Some files are extracted: %s', files);
});

// When all is done
.then(function () {
  console.log('Extracting done!');
});

// On error
.catch(function (err) {
  console.error(err);
});

How to create Sfx - Self Extracting Archives.

Executables will be built using 7-zip version 19.00 on Windows OS for Windows targets. Linux and Apple macOS will use 7-zip version 17.02 for all targets.

import { createSfxWindows, createSfxLinux, createSfxMac } from 'node-7z-archive';

• createSfxWindows(name, files, destination, options, type);

• createSfxLinux(name, files, destination, options);

• createSfxMac(name, files, destination, options);

Each will in turn call: createSfx(name, files, destination, options, type, platform, extension) as:

• name Application name.

• files Files to add.

• destination Application root for the SfxPackages directory, will default to package root.

  • All Sfx package archives are stored in the created SfxPackages directory.
  • The destination directory must already exists.

• options For installer config file and 7-zip switch options.

  • {
  • title: - Window title message, Default "name installation package created on Current running platform OS"
  • beginPrompt: - Begin Prompt message, Default "Do you want to install name?""
  • installPath: - "path_to_extract", Sets the extraction path. The extraction folder will not be deleted after the extraction.
  • progress: - Value can be "yes" or "no". Default value is "yes".
  • runProgram: - Command for executing. Default value is "setup.exe".
  • Substring % % T will be replaced with path to temporary folder,
  • where files were extracted
  • directory: - Directory prefix for RunProgram. Default value is .\
  • executeFile: Name of file for executing
  • executeParameters: Parameters for ExecuteFile
  • }

• type Application type gui or console. Default gui. Only console possible on Linux and Mac OS.
• platform What platform application targeting? Either win32, darwin, or linux.
• extension Binary extension name.

Installation

This package will download the 7zip binaries at install time. Host system does not need to have 7zip installed or in PATH.

The binaries will be downloaded from:

On Windows - https://www.7-zip.org/download.html

On Mac OSX - compiled and available at releases previously https://rudix.org/ which has broken full 7z version.

npm install --save node-7z-archive

CLI

For using full 7zip from command line without installation package.

npm install -g node-7z-archive

Will have createArchive, deleteArchive, extractArchive, fullArchive, listArchive, renameArchive, testArchive, updateArchive, createSfx available globally. To always see available commands, and binary location type:

Advanced usage

Compression method

With the 7z binary compression is made like that:

# adds *.exe and *.dll files to solid archive archive.7z using LZMA method
# with 2 MB dictionary and BCJ filter.
7z a archive.7z *.exe -m0=BCJ -m1=LZMA:d=21

With node-7z-archive you can translate it like that:

import { createArchive } from 'node-7z-archive';

createArchive('archive.7z', '*.exe', {
  m0: '=BCJ',
  m1: '=LZMA:d=21'
})
.then(function () {
  // Do stuff...
});

createArchive, deleteArchive and updateArchive multiple files

When adding, deleting or updating archives you can pass either a string or an array as second parameter (the files parameter).

import { deleteArchive } from 'node-7z-archive';

deleteArchive('bigArchive.7z', [ 'file1', 'file2' ])
.then(function () {
  // Do stuff...
});

Wildcards

You can extract with wildcards to specify one or more file extensions. To do this add a wildcards attribute to the options object. The wildcard attribute takes an Array as value. In this array each item is a wildcard.

import { fullArchive } from 'node-7z-archive';

fullArchive('archive.zip', 'destination/', {
  wildcards: [ '*.txt', '*.md' ], // extract all text and Markdown files
  r: true // in each subfolder too
})
.progress(function (files) {
  // Do stuff with files...
})
.then(function () {
  // Do stuff...
});

Note that the r (for recursive) attribute is passed in this example.

Raw inputs

Sometimes you just want to use the lib as the original command line. For instance you want to apply to switches with different values (e.g.: -i!*.jpg -i!*.png to target only two types of extensions).

In such cases the default behavior of the options argument is not enough. You can use the custom raw key in your options object and pass it an Array of values.

import { listArchive } from 'node-7z-archive';

listArchive('archive.zip', {
  raw: [ '-i!*.jpg', '-i!*.png' ], // only images
})
.progress(function (files) {
  // Do stuff with files...
})
.then(function () {
  // Do stuff...
});
