[!NOTE] Based on the original deterministic-zip by Erwin van der Koogh. Which works fine, but I needed something that I had control over, and I like Typescript, and async.
Regular zip binaries and libraries often generate different zip files from the same files most often because of metadata or timestamps. deterministic-zip-ts guarantees to always generate the same zip file every time.
This is a major problem when creating a reproducible build. The output from two builds from identical source would generate two different zip files.
With deterministic-zip-ts you are guaranteed to get the exact same file every time you build from the same input.
- Now supports async/await
- Supports zip archives with more than 65k files
- Always returns a zip with the exact same hash for files with the same content
- Compresses in parallel, which is somehow faster than native zip (on the machine I tested it with)
- Does not support files larger than 4GB
npm install deterministic-zip-ts --save
import { zip } from 'deterministic-zip-ts';
await zip('data', 'test.zip', {
includes: ['./index.js', './src/**'],
cwd: 'data'
});
