This (single executable) is available in node.js now too as SEA mode.
But I think it still doesn't work with ESM, only CommonJS, so while not insurmountable, not as good as bun.
So is Bun saying that JSC is much better than v8?
>Next: the runtime itself. Bun has a bun build --compile flag that produces a single self-contained executable. No runtime, no node_modules, no source files needed in the container. I didn't know that. So Bun is basically a whole runtime + framework all in one with little to no deployment headaches?
The bun build creates a large self-contained executable with no optimisations. Almost like a large electron build. Deno also provides the same functionality, but with a smaller optimized binary. Appreciate Bun helping creating healthy competition. I feel like Deno falls under most people's radar often. More security options, faster than Node, built on web standards.
There's a PR for Bun that gives the same security but it's been sitting for months https://github.com/oven-sh/bun/pull/25911
I want to migrate an existing project to Bun but cannot until it has a security permission system in place.
They applied optimizations that cut CPU time by ~40% to the Bun version before comparing it with Node. Claiming 5x throughput from "replacing Node.js with Bun" is a wild misrepresentation of the findings.
How much would you get by moving to Go, Rust or C++?
