How I got in love with Deno & Fresh.

In love with #Deno says the author; not so much Deno Deploy.

Build a custom RAG AI agent in TypeScript and Jupyter AI and LLMs are certainly useful assistive tools. But what if we need to train LLMs on confidential documents and materials? Here's how you can build your own custom RAG AI agent.

The Dino 🦕, the Llama 🦙, and the Whale 🐋 Did you know you can run a large language model with Deno and Jupyter Notebooks? Here's how.

Want to play around with LLMs in 5 minutes?

A jupyter notebook running the Deno kernel and working through the process of creating a large language model retrieval augmented generation system.

The joy of Jupyter notebooks and @deno.land. I knew for a while that a Jupyter kernel was built into Deno, but never had reason to use it, but doing some experimentation with LLMs and RAGs seemed like the right opportunity and what a joy.

The next version of Deno will have a super fast JS/TS plugin API for the linter 🎉

Watch @lcas.dev write a lint rule to ban string literals in <60 seconds.

This, plus many other goodies, to land next week with Deno 2.2.

Introducing the JSR open governance board JSR, a modern open source JavaScript registry, is meant for the greater JavaScript and TypeScript community. We're thrilled to announce its own independent governing body.

@jsr.io is now openly governed — meet its board members and check out its governance charter 👇

#FreeJavaScript update: Oracle has informed us they won’t voluntarily withdraw their trademark on "JavaScript". Next: they’ll file their Answer and we’ll start discovery to show how "JavaScript" is widely recognized as a generic term and not controlled by Oracle.

@dc0d/dion - JSR @dc0d/dion on JSR: dion is a simple yet powerful dependency injection container

Created my first #deno /jsr module - a dumb simple DI container jsr.io/@dc0d/dion

With an example hono web api using it: github.com/dc0d/dion-ex...

The experience of using deno was a delight. And deploying to jsr using GitHub workflows was also straight forward.

We have an open bounty for improving Deno support in Rspack. You can find more details at github.com/web-infra-de...

If you find Rspack valuable for your project, please consider sponsoring us through opencollective.com/rspack.

I’ve used Deno for this and it’s an absolute joy compared to doing it the old fashioned way. I’ve used TSDX as well and found it to be fine but with Deno it’s painless.

CSS only smooth Back to Top ...

Needed a "back to top" button for the docs. Made this little example, cos I'm loving the scroll-timeline CSS property allowing for a CSS only, appear on scroll, smooth scrolling, back to top. (chromium/edge only for now)

Bash alias is `alias serve="deno run --allow-read --allow-net jsr:@std/http/file-server"` Usage: `serve` or `serve -p 8080` to pass a port

I made a @deno.land alias to serve the current directory using built-in file server. This replaces `npx serve` for me.

If you've got an easier one LMK!

Deno v. Oracle: Canceling the JavaScript Trademark Oracle is holding the JavaScript trademark hostage, and we’re pursuing legal means to #FreeJavaScript. Here’s a brief update.

It's done. Now it’s your turn, Oracle.

We’ve submitted a formal petition to cancel the JavaScript trademark: it is generic, Oracle has abandoned it, and Oracle committed fraud on the USPTO during the last trademark renewal.

It's time to #FreeJavaScript.
