llrt VS hono

Any plans to add support for? https://github.com/awslabs/llrt

It would also be nice to have a V8/deno/bun based edge hosting option that supports the Next.js edge and middleware code splitting. That's the missing piece for most homebrew "edge" setups. Production CDNs like Clouflare and Supabase all offer this.

Its refreshing to see all the various JS engines that are out there for various usecases.

I have been working on providing quickjs with more node compatible API through llrt [1] for embedding into applications for plugins.

AWS has open-sourced its JavaScript runtime, called LLRT (Low Latency Runtime), an experimental, lightweight JavaScript runtime designed to address the growing demand for fast and efficient Serverless applications.

FROM --platform=arm64 busybox WORKDIR /var/task/ COPY app.mjs ./ ADD https://github.com/awslabs/llrt/releases/latest/download/llrt-container-arm64 /usr/bin/llrt RUN chmod +x /usr/bin/llrt ENV LAMBDA_HANDLER "app.handler" CMD [ "llrt" ]

Let’s get the simplest use case out of the way: cases where the cold starts are so fast that it’s not an issue for you. That’s usually the case for function that use runtimes such as C++, Go, Rust, and LLRT. However, you must follow the best practices and optimizations in every runtime to maintain a low impact cold start.

But compared to other runtimes, LLRT is not so good in terms of performance when it comes to dealing with large data processing, Monte Carlo simulations, or performing tasks with a large number of iterations. The AWS team says that it is best suited for working with smaller Serverless functions dedicated to tasks such as data transformation, real-time processing, AWS service integrations, authorization, validation, etc. Visit the GitHub repository of this project to learn more information.

And lastly, lean into your cloud vendor. Stop trying to build a better mouse trap. Advances in technology are happening all the time. The speed of AWS' Lambda has been rapidly improving over the past couple of years with the launch of things like SnapStart and LLRT

Today we'll try to answer these questions by looking at some methods to stream real-time data and build our own small real-time stock market feed app in Hono and React to illustrate the differences between these methods. For the visual side of things we'll be using shadcn charts to display randomly generated data.

But that’s not all. The framework offers a powerful routing system (inspired by the fantastic Hono), integrated asset management with Cloudflare R2, and an elegant way to handle errors via the HttpError class. Middlewares can easily send data to the client through a shared store, and everything is automatically obfuscated for security.

Hono is the creation of Yusuke Wada. He started the project 2021 because there were no good Node.js frameworks that worked well on Cloudflare Workers. Since then Hono as added support for a lot of other runtimes like Node.js, Bun and Deno.

Hono: A small, simple, and ultrafast web framework for Deno, Bun, and Node.js

My guess is Express has been stable for a long time with no real need to evolve it. And old versions of node have effectively expired, so they can now drop support.

Most likely there are more API changes planned for v6 and v5 is the stepping stone.

For personal projects, I've been loving https://hono.dev/ The DX is fantastic and it runs in bun and CloudFlare workers. Shoutout to the hono developers!

For larger team projects, I end up using Fastify and NextJS. No real reason other than it's what's already running or other devs on the projects prefer it.

In this guide, we're using Hono.js as our web framework, but you can use any web framework or web server of your choice. The core concepts will remain the same regardless of the framework you choose. The only thing to be aware of about the SDK is, for the moment, the only languages supported are TypeScript and JavaScript.

hono.dev is a library similar to express.js, providing solutions for building APIs. But why hono? Look at Cloudflare Workers' simple endpoint guide below:

We’ll cover setting up your local environment to handle webhook events and processing the payload in a TypeScript application. Our exmaple is built with the HONC stack. The stack consists Hono.js as the web framework, a PostgreSQL Serverless database (Neon), the ORM Drizzle, and the setup to run as a Cloudflare Worker.

The following tutorial will be using hono (nodejs) to get the request header, it can be done with any language, you just need be able to access the request headers.
