**[Bytes by ui.dev](https://daily.dev/sources/bytesdev)** · 5 min read · 8 upvotes · 0 comments

## Summary

A developer newsletter covering the launch of Flue, a new TypeScript-based agent harness framework by Fred K. Schott (creator of Astro). Flue enables building and deploying custom AI agents with runtime-agnostic shell abstraction (via just-bash), sandbox flexibility, skill-centric design, and MCP support. Also covers Rolldown v1.0, a new VS Code release, Tanner Linsley rewriting React, a Rust-based TypeScript compiler (tsz), and a JavaScript async error handling tip about try/catch not working with setTimeout.
