Unzip chrome extension files

Build Status Dependency Status Coverage Status

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 lib is highly inspired by crx2ff from abarreir, thanks!


$ npm install unzip-crx


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

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

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


unzip(file[, destination])

Resolves with a Promise if the file was unzipped successfully, throws otherwise (use .catch()).
