Unzip chrome extension files

If you want to unzip Chrome extension files (*.crx) you might have the problem that your unzip lib claims that the file header is malformed. This is due to that Chrome adds some extra information for identifying crx files. unzip-crx handles those additional headers and unzips as usual.

This library is based on Peerigon's unzip-crx, which makes simple modifications and adds esm and cjs support.

And this unzip-crx is highly inspired by crx2ff from abarreir and crxviewer from Rob Wu, thanks!

Install

# pnpm
pnpm add @tomjs/unzip-crx

# npm

Example

• esm

import unzip from 'unzip-crx';

const crxFile = './this-chrome-extension.crx';

unzip(crxFile).then(() => {
  console.log('Successfully unzipped your crx file..');
});

• cjs

const unzip = require('unzip-crx');

const crxFile = './this-chrome-extension.crx';

unzip(crxFile).then(() => {
  console.log('Successfully unzipped your crx file..');
});
