Developer launches @rabbx/sirv, a zero-dependency static file middleware for edge runtimes

·2 views

A developer has released @rabbx/sirv, a rewrite of the popular sirv static file middleware designed natively for edge and modern runtimes including Bun, Deno, Node.js, and Cloudflare Workers. Unlike the original sirv, which was built for Node.js and requires polyfills on other runtimes, @rabbx/sirv uses native Web APIs such as Request, Response, and ReadableStream from the ground up. The library introduces a composable plugin system with setHeaders and transform hooks, enabling use cases like Markdown-to-HTML conversion in roughly 20 lines of code. Leveraging zero-copy streaming on Bun, the middleware reportedly achieves around 95,000 requests per second with 0.3ms latency. The project is MIT-licensed, has zero dependencies, and is described as production-ready.

Cordless v0.6 Launches CLI-First Terminal Dashboard with QR Pairing and Self-Contained Binary

Cordless, a tool for managing remote terminal and coding-agent sessions on mobile, has released version 0.6 with a redesigned CLI-first approach. Running the app now opens a full-screen terminal dashboard that immediately displays a pairing QR code, eliminating the need to run a separate pairing command. The update ships as a single self-contained binary bundling its own Node.js runtime and node-pty, removing any prior installation requirements. Security has also been tightened, with pairing codes now issued exclusively through an authenticated WebSocket call restricted to loopback connections, making remote device enrollment impossible. The persistent daemon architecture ensures that closing the dashboard never interrupts active sessions or phone connections.

Common jq Pitfalls in Shell Scripts and How to Handle Them

Developers and sysadmins using jq to process JSON in shell scripts often encounter edge cases that work in testing but fail in production. Key issues include improper null handling and unexpected behavior when querying missing or empty fields. Using flags like -r for raw string output and -e to detect null results with exit code 5 can help catch these problems early. Defensive scripting patterns, such as explicit null checks and error exits, are recommended to avoid hard-to-debug production failures. These are not flaws in jq itself but rather subtleties that arise when combining shell scripting with real-world JSON data processing.

SOLID Principles Explained: Five Rules for Cleaner, Scalable Software Design

SOLID is a set of five software design principles aimed at improving code quality, scalability, and maintainability. The Single Responsibility Principle states that each class should have only one reason to change, avoiding so-called 'God Classes' that handle multiple concerns at once. The Open/Closed Principle advises that code should be open for extension but closed for modification, reducing reliance on conditional logic when adding new features. The Liskov Substitution Principle requires that child classes can replace parent classes without breaking the application, encouraging more careful inheritance planning. The Interface Segregation Principle holds that no class should be forced to depend on methods it does not need, favoring smaller, purpose-specific interfaces over large, all-encompassing ones.
