Unzipper - Zip Compression and Extraction Tool

Installation$ npm install unzipperOpen methodsThe open methods allow random access to the underlying files of a zip archive, from disk or from the web, s3 or a custom source.The open methods return a promise on the contents of the central directory of a zip file, with individual files listed in an array.Each file record has the following methods, providing random access to the underlying files:stream([password]) - returns a stream of the unzipped content which can be piped to any destinationbuffer([password]) - returns a promise on the buffered content of the file.If the file is encrypted you will have to supply a password to decrypt, otherwise you can leave blank.Unlike adm-zip the Open methods will never read the entire zipfile into buffer.The last argument to the Open methods is an optional options object where you can specify tailSize (default 80 bytes), i.e. how many bytes should we read at the end of the zipfile to locate the endOfCentralDirectory. This location can be variable depending on zip64 extensible data sector size. Additionally you can supply option crx: true which will check for a crx header and parse the file accordingly by shifting all file offsets by the length of the crx header.Open.file([path], [options])Returns a Promise to the central directory information with methods to extract individual files. start and end options are used to avoid reading the whole file.Here is a simple example of opening up a zip file, printing out the directory information and then extracting the first file inside the zipfile to disk:async function main() { const directory = await unzipper.Open.file('path/to/archive.zip'); console.log('directory', directory); return new Promise( (resolve, reject) => { directory.files[0] .stream() .pipe(fs.createWriteStream('firstFile')) .on('error',reject) .on('finish',resolve) });}main();If you want to extract all files from the zip file, the directory object supplies an extract method. Here is a quick example:async function main() { const directory = await unzipper.Open.file('path/to/archive.zip'); await directory.extract({ path: '/path/to/destination' })}Open.url([requestLibrary], [url | params], [options])This function will return a Promise to the central directory information from a URL point to a zipfile. Range-headers are used to avoid reading the whole file. Unzipper does not ship with a request library so you will have to provide it as the first option.Live Example: (extracts a tiny xml file from the middle of a 500MB zipfile)const request = require('request');const unzipper = require('./unzip');async function main() { const directory = await unzipper.Open.url(request,' const file = directory.files.find(d => d.path === 'tl_2015_us_zcta510.shp.iso.xml'); const content = await file.buffer(); console.log(content.toString());}main();This function takes a second parameter which can either be a string containing the url to request, or an options object to invoke the supplied request library with. This can be used when other request options are required, such as custom headers or authentication to a third party service.const request = require('google-oauth-jwt').requestWithJWT();const googleStorageOptions = { url: ` qs: { alt: 'media' }, jwt: { email: google.storage.credentials.client_email, key: google.storage.credentials.private_key, scopes: [' }});async function getFile(req, res, next) { const directory = await unzipper.Open.url(request, googleStorageOptions); const file = zip.files.find((file) => file.path === 'my-filename'); return file.stream().pipe(res);});Open.s3([aws-sdk], [params], [options])This function will return a Promise to the. 7-Zip is the most popular Windows, Mac Linux alternative to unzipper. 7-Zip is the most popular Open Source free alternative to unzipper. 7-Zip is Free and Open Source unzipper is also Free and Open Source; 7-Zip is Lightweight unzipper is not according to our users Unzip and Zip files with Unzipper, a versatile file archiver for easy compression and extraction. about features file types Get Unzipper.

Trouble Shooting Zip Problems with Unzipper

Central directory information from a zipfile on S3. Range-headers are used to avoid reading the whole file. Unzipper does not ship with with the aws-sdk so you have to provide an instantiated client as first arguments. The params object requires Bucket and Key to fetch the correct file.Example:const unzipper = require('./unzip');const AWS = require('aws-sdk');const s3Client = AWS.S3(config);async function main() { const directory = await unzipper.Open.s3(s3Client,{Bucket: 'unzipper', Key: 'archive.zip'}); return new Promise( (resolve, reject) => { directory.files[0] .stream() .pipe(fs.createWriteStream('firstFile')) .on('error',reject) .on('finish',resolve) });}main();Open.buffer(buffer, [options])If you already have the zip file in-memory as a buffer, you can open the contents directly.Example:// never use readFileSync - only used here to simplify the exampleconst buffer = fs.readFileSync('path/to/arhive.zip');async function main() { const directory = await unzipper.Open.buffer(buffer); console.log('directory',directory); // ...}main();Open.custom(source, [options])This function can be used to provide a custom source implementation. The source parameter expects a stream and a size function to be implemented. The size function should return a Promise that resolves the total size of the file. The stream function should return a Readable stream according to the supplied offset and length parameters.Example:// Custom source implementation for reading a zip file from Google Cloud Storageconst { Storage } = require('@google-cloud/storage');async function main() { const storage = new Storage(); const bucket = storage.bucket('my-bucket'); const zipFile = bucket.file('my-zip-file.zip'); const customSource = { stream: function(offset, length) { return zipFile.createReadStream({ start: offset, end: length && offset + length }) }, size: async function() { const objMetadata = (await zipFile.getMetadata())[0]; return objMetadata.size; } }; const directory = await unzipper.Open.custom(customSource); console.log('directory', directory); // ...}main();Open.[method].extract()The directory object returned from Open.[method] provides an extract method which extracts all the files to a specified path, with an optional concurrency (default: 1).Example (with concurrency of 5):unzip.Open.file('path/to/archive.zip') .then(d => d.extract({path: '/extraction/path', concurrency: 5}));Please note: Methods that use the Central Directory instead of parsing entire file can be found under OpenChrome extension files (.crx) are zipfiles with an extra header at the start of the file. Unzipper will parse .crx file with the streaming methods (Parse and ParseOne).Streaming an entire zip file (legacy)This library began as an active fork and drop-in replacement of the node-unzip to address the following issues:finish/close events are not always triggered, particular when the input stream is slower than the receiversAny files are buffered into memory before passing on to entryOriginally the only way to use the library was to stream the entire zip file. This method is inefficient if you are only interested in selected files from the zip files. Additionally this method can be error prone since it relies on the local file headers which could be wrong.The structure of this fork is similar to the original, but uses Promises and inherit guarantees provided by node streams to ensure low memory footprint and emits finish/close events at the end of processing. The new Parser will push any parsed entries downstream if you pipe from it, while still supporting the legacy entry event as well.Breaking changes: The new Parser will not automatically drain entries if there are no listeners or pipes in

Doesn't already exist.Parse zip file contentsProcess each zip file entry or pipe entries to another stream.Important: If you do not intend to consume an entry stream's raw data, call autodrain() to dispose of the entry'scontents. Otherwise the stream will halt. .autodrain() returns an empty stream that provides error and finish events.Additionally you can call .autodrain().promise() to get the promisified version of success or failure of the autodrain. handleError);// orentry.autodrain().on('error' => handleError);">// If you want to handle autodrain errors you can either:entry.autodrain().catch(e => handleError);// orentry.autodrain().on('error' => handleError);Here is a quick example:fs.createReadStream('path/to/archive.zip') .pipe(unzipper.Parse()) .on('entry', function (entry) { const fileName = entry.path; const type = entry.type; // 'Directory' or 'File' const size = entry.vars.uncompressedSize; // There is also compressedSize; if (fileName === "this IS the file I'm looking for") { entry.pipe(fs.createWriteStream('output/path')); } else { entry.autodrain(); } });and the same example using async iterators:const zip = fs.createReadStream('path/to/archive.zip').pipe(unzipper.Parse({forceStream: true}));for await (const entry of zip) { const fileName = entry.path; const type = entry.type; // 'Directory' or 'File' const size = entry.vars.uncompressedSize; // There is also compressedSize; if (fileName === "this IS the file I'm looking for") { entry.pipe(fs.createWriteStream('output/path')); } else { entry.autodrain(); }}Parse zip by piping entries downstreamIf you pipe from unzipper the downstream components will receive each entry for further processing. This allows for clean pipelines transforming zipfiles into unzipped data.Example using stream.Transform:fs.createReadStream('path/to/archive.zip') .pipe(unzipper.Parse()) .pipe(stream.Transform({ objectMode: true, transform: function(entry,e,cb) { const fileName = entry.path; const type = entry.type; // 'Directory' or 'File' const size = entry.vars.uncompressedSize; // There is also compressedSize; if (fileName ===. 7-Zip is the most popular Windows, Mac Linux alternative to unzipper. 7-Zip is the most popular Open Source free alternative to unzipper. 7-Zip is Free and Open Source unzipper is also Free and Open Source; 7-Zip is Lightweight unzipper is not according to our users
