jray: JSON CLI Built with Bun and TypeScript
A developer built and published jray, a small open-source JSON CLI written in TypeScript and compiled with Bun. jray flattens JSON to dot-notation, supports glob-style filtering, colorized TTY output, NDJSON streaming, and can fetch JSON from URLs. The project compiles to a single binary via bun build --compile and is published to npm as @siyadkc/jray with source on GitHub. The author documents practical issues encountered (npm name conflict requiring a scoped package, large npm package payload until files was set, Windows postinstall chmod failures, and CI lockfile handling) and shares CI/publishing tips and a live GitHub Pages playground.
A small open-source developer tool release useful for developer productivity but not directly relevant or impactful to the AdTech/MarTech industry at large.

Key Takeaways & Evidence Grounding
- The author created jray, a JSON CLI that flattens JSON, filters by glob-style key patterns, colorizes output, streams NDJSON, and can fetch from URLs.
- jray is implemented in TypeScript and built with the Bun runtime; it can be compiled into a single binary using bun build --compile.
- The package is published to npm under the scoped name @siyadkc/jray and the source repository is on GitHub (github.com/siyadhkc/jray).
- Noted engineering issues included an npm name conflict (required switching to a scoped package), excessive npm package size until a files field was added, a Windows postinstall chmod problem, and the recommendation to use bun install --frozen-lockfile in CI.

Bun vs Node.js in 2026: Production Readiness
This technical review compares Bun (tested at v1.2.x) against Node.js 22 LTS on real-world workloads including an Astro + Drizzle + Postgres stack, a Hono API, and a 14-package monorepo. Bun is a single binary runtime built on JavaScriptCore and written in Zig that bundles a package manager, test runner, bundler, and script runner (bun install/test/build/run). Benchmarks show Bun excels at cold package installs, short-script startup time, and synthetic HTTP throughput; real application gains are smaller due to DB drivers and application code dominating hot paths. The article highlights compatibility frictions—native node-gyp modules, subtle process/cluster differences, test-migration edge cases, and workspace tooling assumptions—and recommends using Bun selectively (e.g., for CI installs or greenfield projects) while keeping Node for production on platforms that don’t run Bun. It also notes Node.js 22 has absorbed several developer-experience features previously unique to Bun.
3va: Rust-built JS/TS runtime with strict permissions
3va v2.0.2 is a JavaScript and TypeScript runtime implemented in Rust that enforces capability-based permissions by default. The runtime blocks filesystem, network, environment, child processes, and native addon access unless explicitly allowed, and it unconditionally prevents post-install scripts from running. 3va installs from standard registries (npm, Yarn, etc.), aims to be compatible with common frameworks (Next.js, React, Express, Fastify and others), and bundles a package manager, built-in process manager, test runner, bundler, DDoS protections, and post-quantum cryptography primitives. The author publishes benchmarks comparing 3va (debug build) with Node.js and Bun—acknowledging Bun’s superior raw throughput and startup—but emphasizes 3va’s security and permission isolation as its primary value. Multiple install channels are provided (npm, Homebrew, Chocolatey, Scoop, cargo, Flatpak).
Bun + Cosmic: Fastest JavaScript Stack for 2026
A developer tutorial and performance overview demonstrating a Bun v1.3 runtime combined with Cosmic (a CDN-backed headless CMS) as a high-performance full-stack for content-heavy JavaScript apps in 2026. The article highlights Bun's fast startup, package installation, native TypeScript support, and recent features (zero-config frontend, unified SQL API, built-in Redis and image APIs, HTTP/3). It notes Anthropic acquired Bun in December 2025 and that Vercel added native Bun runtime support in October 2025. Cosmic's REST API and JavaScript SDK provide cached CDN-backed content with typical cached responses under 100ms. The piece includes step-by-step setup instructions (bun init, bun add @cosmicjs/sdk, createBucketClient) and example Bun.serve server code to fetch and serve Cosmic content without additional frameworks.
