# ADM-ZIP for NodeJS with added support for electron original-fs ADM-ZIP is a pure JavaScript implementation for zip data compression for [NodeJS](http://nodejs.org/). # Installation With [npm](http://npmjs.org) do: $ npm install adm-zip ## What is it good for? The library allows you to: * decompress zip files directly to disk or in memory buffers * compress files and store them to disk in .zip format or in compressed buffers * update content of/add new/delete files from an existing .zip # Dependencies There are no other nodeJS libraries that ADM-ZIP is dependent of # Examples ## Basic usage ```javascript var AdmZip = require('adm-zip'); // reading archives var zip = new AdmZip("./my_file.zip"); var zipEntries = zip.getEntries(); // an array of ZipEntry records zipEntries.forEach(function(zipEntry) { console.log(zipEntry.toString()); // outputs zip entries information if (zipEntry.entryName == "my_file.txt") { console.log(zipEntry.getData().toString('utf8')); } }); // outputs the content of some_folder/my_file.txt console.log(zip.readAsText("some_folder/my_file.txt")); // extracts the specified file to the specified location zip.extractEntryTo(/*entry name*/"some_folder/my_file.txt", /*target path*/"/home/me/tempfolder", /*maintainEntryPath*/false, /*overwrite*/true); // extracts everything zip.extractAllTo(/*target path*/"/home/me/zipcontent/", /*overwrite*/true); // creating archives var zip = new AdmZip(); // add file directly var content = "inner content of the file"; zip.addFile("test.txt", Buffer.alloc(content.length, content), "entry comment goes here"); // add local file zip.addLocalFile("/home/me/some_picture.png"); // get everything as a buffer var willSendthis = zip.toBuffer(); // or write everything to disk zip.writeZip(/*target file name*/"/home/me/files.zip"); // ... more examples in the wiki ``` For more detailed information please check out the [wiki](https://github.com/cthackers/adm-zip/wiki).
