Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It has three major design goals:
Speed. Bun starts fast and runs fast. It extends JavaScriptCore, the performance-minded JS engine built for Safari. As computing moves to the edge, this is critical.
Elegant APIs. Bun provides a minimal set of highly-optimimized APIs for performing common tasks, like starting an HTTP server and writing files.
Cohesive DX. Bun is a complete toolkit for building JavaScript apps, including a package manager, test runner, and bundler.
Bun is designed as a drop-in replacement for Node.js. It natively implements hundreds of Node.js and Web APIs, including fs, path, Buffer and more.
The goal of Bun is to run most of the world's server-side JavaScript and provide tools to improve performance, reduce complexity, and multiply developer productivity.

I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.
Based on our record, Bun.sh should be more popular than StackBlitz. It has been mentiond 227 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 6 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 9 months ago

Then fine-grained reactivity is added to achieve efficient DOM updates + minimal payload size.... - Source: Hacker News / 9 months ago
In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / over 1 year ago

The Node.js ecosystem has powered bots for a decade via discord.js. However, the Bun runtime has completely changed the game. Bun acts as an all-in-one JavaScript toolkit that starts up significantly faster and utilizes memory far more efficiently than standard Node.js. - Source: dev.to / 19 days ago
The binary had a #!/usr/bin/env bun shebang and imported bun:sqlite. I had developed the whole thing under Bun, so on my machine it was perfect. On a normal machine with only Node installed, there is no bun to run the shebang, the entry was a .ts file Node would not execute, and even if it got that far, bun:sqlite is a built-in that only exists inside Bun. Three separate ways to fail before any of my code ran.... - Source: dev.to / about 2 months ago
The CLI is a thin Bun wrapper; the engine is the Rust binary it shells out to. Pipe-friendly by design โ transcript on stdout, errors on stderr. - Source: dev.to / about 2 months ago
The numbers are striking. According to benchmarks published on bun.sh, Bun handles 59,026 Express.js "hello world" HTTP requests per second on Linux x64, compared to 25,335 for Deno and 19,039 for Node.js. For WebSocket throughput, Bun clocks 2,536,227 messages per second against Deno's 1,320,525 and Node's 435,099. Bun also bundles 10,000 React components in 269ms. Rolldown completes the same job in 495ms.... - Source: dev.to / 2 months ago
Toolchains: I use SDKMAN! For JDKs, NVM for Node.js, rustup for Rust, Bun, Go, Python, Deno, and the usual Linux build tools. - Source: dev.to / 2 months ago
