A collection of utilities for TypeScript and JavaScript.

This repository is work in progress.

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

• @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

Planned for this utility package:

• hashes - sha256, sha512, etc.

Other tools that I regularly use and don't feel the need to optimize or re-create in this utility package:

• axios - Promise based HTTP client for the browser and node.js
• hono - small, simple, and ultrafast web framework built on Web Standards
• undici - performant HTTP/1.1 client for Node.js
• @upstash/redis for HTTP redis and redis for TCP
• tailwindcss - CSS framework for rapid UI development
• @turf/turf for anything geospatial

Use deno fmt, deno lint and biome lint to check the code.

deno task check

See Writing documentation for details about writing JSDoc.

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

deno task test

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).
