Utility packages

A collection of utilities for TypeScript and JavaScript.

The primary repository lives on tangled.org, which gets synced to github.com.

It is tested against Bun, Deno, and Node.js runtimes. Published on jsr.io (@frytg).

Tools

• @frytg/check-required-env - Check a required environment variable
• @frytg/crypto - Crypto utilities (hash, hmac, etc.)
• @frytg/dates - Date utilities around Luxon
• @frytg/logger - Pre-configuredWinston logging wrapper

Lint

Uses Biome to check the code.

See Writing documentation for details about writing JSDoc.

Testing

This uses @cross/test and sinon to run the tests.

For Node.js and Bun, install dependencies with Nub and run tests:

nub install
nub run test

Publish

Locally check if everything is ok:

deno publish --dry-run

Then once everything is pushed or merged on main, run the GitHub actions workflow to publish the packages to JSR (see publishing packages for more details).
