It avoids heavy Node-specific shims and large dependency trees. Key features include zero-copy streaming on Bun for low latency, a composable plugin system with setHeaders and transform hooks, and native Web API support for consistent behavior across CF Workers and Deno. ## Content We spend hours optimizing database queries, but completely ignore how we serve static assets. I built `@rabbx/sirv` to fix the static file story across edge runtimes (Bun, Deno, Node, CF Workers). The catch with most static middleware is they rely on heavy Node-specific shims or pull in massive dependency trees. `@rabbx/sirv` is zero-dependency and built for the edge. Key architectural choices: - Zero-copy streaming on Bun to keep latency flat. - A composable plugin system (`setHeaders` + `transform`) so you aren't forced into a rigid middleware chain. - Native Web API support so it runs identically on CF Workers and Deno. If you're building on the edge and tired of bloated static servers, check it out. https://github.com/rabbxdev/sirv ## Similar posts on daily.dev - [VoidZero’s Rolldown Library: Rollup Compatible API with the Speed Of Rust](https://daily.dev/posts/voidzero-s-rolldown-library-rollup-compatible-api-with-the-speed-of-rust-qe7qd6dlx) · InfoQ · 0 upvotes · 0 comments - [Serving a website with Cloudflare Workers static assets](https://daily.dev/posts/serving-a-website-with-cloudflare-workers-static-assets-ast0sepwo) · Flavio Copes · 1 upvotes · 0 comments - [Bun v1.3.6](https://daily.dev/posts/bun-v1-3-6-wx4br4zyw) · Bun · 94 upvotes · 1 comments --- Tags: [#edge-computing](https://daily.dev/tags/edge-computing), [#bun](https://daily.dev/tags/bun) [View this post on daily.dev](https://daily.dev/posts/next-gen-static-file-middleware-rabbx-sirv--kfzz9o0tw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/next-gen-static-file-middleware-rabbx-sirv--kfzz9o0tw","headline":"next Gen static file middleware (@rabbx/sirv)","text":"@rabbx/sirv is a zero-dependency static file middleware built for edge runtimes including Bun, Deno, Node.js, and Cloudflare Workers.
