Deno is joining Cloudflare
AI-generated overview
Cloudflare is acquiring Deno and plans to build on celld, Deno's open-source implementation of the Durable Objects pattern, to make self-hosting workerd a supported way to build and run Workers-style applications. Cloudflare says it will maintain the Deno runtime with monthly bug-fix and security releases for one year, then stop development; Deno will remain open source. Creator Ryan Dahl supports the decision, arguing that Node.js compatibility limited Deno's differentiation and that celld represents a more novel approach to server development. The article also compares Deno and Node.js permissions, noting that Node.js does not yet allow network access to be restricted to specific hosts.
