ADM-ZIP is a pure JavaScript zip library for NodeJS with no external dependencies. It can create, read, update, and extract zip archives either in memory buffers or directly to/from disk, including support for Electron's original-fs.

Use cases

• extract zip files to disk in node
• create zip archives from files or buffers
• read zip entry contents in memory without writing to disk
• add, update, or delete files inside an existing zip
• package files into a zip buffer to send over http
• work with zips inside electron apps using original-fs

When to choose

• you need a zero-dependency zip library for NodeJS
• you want to manipulate zip archives in memory as buffers
• you need to modify existing zips (add/update/delete entries)
• you're building an Electron app that needs zip support

When to avoid

• you need maximum compression performance or native speed
• you need formats other than zip (tar, gzip, 7z)
• you need streaming processing of very large archives
• you need advanced encryption features beyond password-protected reading
