Thank You, Deno
news
7 min read
Deno’s team is joining Cloudflare, and the Deno runtime will wind down over the next year. Cloudflare will continue operating the JSR JavaScript registry on its infrastructure, while the team works to merge Deno’s celld technology into workerd, Cloudflare’s open-source runtime for Workers. Ryan Dahl announced the move two years after Deno 2 shipped; Bun joined Anthropic about 10 months earlier. Deno launched in 2020 with deny-by-default permissions, first-class TypeScript, web-standard server APIs, ES modules, a single executable and URL-based dependencies instead of npm packages and node_modules. It later added deps.ts, lock files, import maps and npm compatibility; Deno 2, released in October 2024, added full Node and npm compatibility. The source credits competing runtimes with accelerating Node additions including global fetch, WebSocket, Web Streams, Web Crypto, a stable permission model, type stripping, node:sqlite and require(esm). It also cites competition among package managers as contributing to deterministic lockfiles, workspaces, offline caches, smaller node_modules installations and changes to install-script defaults. GitHub announced in June that npm 12 would stop running install scripts by default after supply-chain worms. The source says a community Deno fork could test demand for an independent secure-by-default, standards-focused runtime.
Bun 1.4
tool
202 min read
Bun 1.4 updates the JavaScript and TypeScript runtime, package manager, test runner, and bundler with a Rust rewrite, expanded Node.js compatibility, lower resource use, and new built-in APIs. The release adds 1,517 Node.js test-suite tests and fixes more than 2,900 issues. Bun reports that node:http, fs, cluster, timers, zlib, vm, and stream now pass 97% of Node’s own tests, while node:quic passes 99% and node:events, trace_events, and sqlite pass 100%. Bun says idle CPU use falls fivefold for a small application, HTTP-server memory use declines by 13% to 48%, and Linux startup time for a hello-world script drops from 10.9 ms in Bun 1.3 to 5.1 ms. New native Web Streams, CompressionStream and DecompressionStream implementations, and improved response cloning reduce memory use and improve streaming throughput. New built-ins include Bun.Image for image conversion and resizing, Bun.WebView for browser automation, Bun.markdown, Bun.cron(), and Bun.Terminal. Package-management additions include bun audit fix, bun dedupe, bun prune, package diffs, license reporting, and transitive dependency updates. Bun 1.4 also adds parallel script and test execution, test sharding and timing-based balancing, built-in React Compiler support, directory serving in Bun.serve(), and experimental HTTP/2 and HTTP/3 capabilities.
