Zip-a-folder NPM

zip-a-folder

Easy to use zip (or tar) a complete folder or a list of globs plain into a zip/tar/tgz file including compression ratio handling and custom write streams.

incompatible changes

Version 2 adds glob lists handling as a src. So please be aware that using globs intentionally breaks up the "create-a-zip/tar-file-from-a-folder" approach.
Version 3 adds the possibility to zip-a-folder to be usable either in commonjs or esm module environments.
Version 3.1 adds the possibility to specify target folder within a zip file. By default the structure within a zip file doesn't contain the src folder, but the files and folder underneath.

Basic Usage

Install via npm

npm install zip-a-folder

Creating a ZIP file

import { zip } from 'zip-a-folder';

class TestMe {

    static async main() {
        await zip('/path/to/the/folder', '/path/to/archive.zip');
    }
}

TestMe.main();

Creating a gzipped TAR file

import { tar } from 'zip-a-folder';

class TestMe {

    static async main() {
        await tar('/path/to/the/folder', '/path/to/archive.tgz');
    }
}

TestMe.main();

Compression handling

For the sake of easy use, supported compression levels are (by now): COMPRESSION_LEVEL.high, COMPRESSION_LEVEL.medium or COMPRESSION_LEVEL.uncompressed.

The default compression - level is high.

import { zip, COMPRESSION_LEVEL } from 'zip-a-folder';

class TestMe {

    static async main() {
        await zip('/path/to/the/folder', '/path/to/archive.zip', {compression: COMPRESSION_LEVEL.high});
    }
}

TestMe.main();

Custom writeStreams

You can now pipe output to any WriteStream (just pass WriteStream as a parameter).

To keep the existing api stable the 2nd parameter (targetFilePath) can now be either undefined or an empty string.

ATTENTION: customWriteStream is not checked. So it is up to the user to check on non-existing target folders or if the targetfolder equals to the sourcefolder (ending up in circularity).

import { zip, COMPRESSION_LEVEL } from 'zip-a-folder';
import { fs } from 'fs';

class TestMe {
    static async main() {
        const customWS = fs.createWriteStream('test/1234.zip');
        await zipafolder.zip(path.resolve(__dirname, 'data/'), undefined, {customWriteStream: customWS});    
    }
}

TestMe.main();

Glob handling

The first parameter can be either a path or a glob. Globs are separated by comma.

import {zip} from 'zip-a-folder';

class TestMe {

    static async main() {
        // zip all json into an archive
        await zip('**/*.json', '/path/to/archive.zip');
        // zip all json AND txt files into a second archive
        await zip('**/*.json, **/*.txt', '/path/to/archive2.zip');
    }
}

TestMe.main();

Destination path handling (>=3.1.x)

With passing a destination path to zip-a-folder options object you can define the target folder structure within the generated zip.

import {zip} from 'zip-a-folder';

class TestMe {

    static async main() {
        // zip all json into an archive
        await zip('data/', '/path/to/archive.zip', {destPath: 'data/'});
    }
}

TestMe.main();
