npm install @mongodb-js/zstd
Zstandard compression library for Node.js
``
npm install @mongodb-js/zstd
Releases are created automatically and signed using the Node team's GPG key. This applies to the git tag as well as all release packages provided as part of a GitHub release. To verify the provided packages, download the key and import it using gpg:
`
gpg --import node-driver.asc
The GitHub release contains a detached signature file for the NPM package (named
mongodb-js-zstd-X.Y.Z.tgz.sig).
The following command returns the link npm package.
`shell`
npm view @mongodb-js/zstd@vX.Y.Z dist.tarball
Using the result of the above command, a curl command can return the official npm package for the release.
To verify the integrity of the downloaded package, run the following command:
`shell`
gpg --verify mongodb-js-zstd-X.Y.Z.tgz.sig mongodb-js-zstd-X.Y.Z.tgz
>[!Note]
No verification is done when using npm to install the package. The contents of the Github tarball and npm's tarball are identical.
To verify the native .node packages, follow the same steps as above using mongodb-js-zstd-X.Y.Z-platform.tgz and the corresponding .sig file.
Only the following version combinations with the MongoDB Node.js Driver are considered stable.

Change history can be found in HISTORY.md.
`ts
import { compress, decompress } from '@mongodb-js/zstd';
(async () => {
const buffer = Buffer.from('test');
const compressed = await compress(buffer, 10);
const decompressed = await decompress(compressed);
})();
`
First, install and build the zstd library:
npm run install-zstd
Then build the bindings:
npm run prebuild
Then test:
npm test`
