Unlike the previous npm packages, the zlib package is a core Node.js module that provides data compression and decompression functionality using Gzip, Deflate/ Inflate, and Brotli. The code block above extracts all the files in example.zip and populates the dist folder with the extracted files: Here’s how that works: zip.extractAllTo("dist") This method takes a file path as an argument and populates the file path with the file’s contents. Then, you can extract the files where adm-zip was instantiated by calling its extractAllTo method. On the other hand, you can also instantiate it without an existing. zip gives it access to the data in the file. zip by providing the file path as an argument. You can instantiate adm-zip with an existing. Next, create an adm-zip instance: const zip = new AdmZip("./example.zip") Like so: const AdmZip = require("adm-zip") To start unzipping with this package, install it by running the command below: npm install adm-zip The adm-zip package is an npm package used for zip data compression that allows you to decompress zip files directly to the disk or memory buffers. Successfully running the code block above will populate your dist with the resulting files: In the code block above, we used decompress to unzip the example.zip file and populate the dist folder with the resulting files. The optional configuration object uses array methods, such as map or filter, to perform certain operations on the files before extracting them: decompress("example.zip", "dist") The imported decompress method expects three arguments: Next, import the package: const decompress = require("decompress") To start unzipping with this package, install it with the command below: npm install decompress The decompress package is an npm package that simplifies archives extraction without blocking code execution using Promises. Comparing the unzipping packages for Node.js.Create, read, and edit files with the jszip package.In this tutorial, you’ll learn the best methods for zipping and unzipping files in Node.js using the decompress, adm-zip, zlib, unzipper, and jszip packages. Using zip files in your Node.js project effectively reduce file size while mitigating data loss for data sharing and transportation. When zipping a file, the zipping algorithm compresses the file or folder into a zip, where you can retrieve the file by extracting (unzipping) the original format. Zip is one of the most popular data compression algorithms for reducing file size and increasing portability. Some standard algorithms include ZIP, BZIP2, 7-ZIP, JPEG, PEG, and more. Many data compression technologies use underlying algorithms suitable for different operations and file sizes to address this concern. Best methods for unzipping files in Node.jsĪs technology has advanced over the years, the need for more memory consumption and portability has grown.
