The end of Deno, back to node.js

 Thank you, Deno | vlt /vōlt/

Here is a summary of the blog post titled "Thank you, Deno" by Darcy Clarke, CEO of vlt:

• The Announcement: Ryan Dahl announced that the Deno team is joining Cloudflare. Over the next year, the Deno runtime will wind down, JSR will continue running on Cloudflare's infrastructure, and the team will focus on merging Deno's celld into workerd.
  
  
• The Impact of Alternative Runtimes: Although Node.js remains dominant in production, competitors like Deno and Bun injected vital urgency into the JavaScript ecosystem. They forced incumbents to adopt modern features much faster—such as native fetch, permission models, TypeScript support, and test runners—long before they otherwise might have.
  
  
• Evolution of Deno's Approach: Deno launched in 2018 as a radical clean break from Node.js (rejecting npm, package.json, and node_modules in favor of URL imports). Over time, user feedback and competition (such as Bun) led Deno to pivot toward full npm/Node compatibility, culminating in Deno 2.
  
  
• Broader Ecosystem Changes:
  
  
  • Package managers and toolchains (like Yarn, pnpm, Bun, and vlt) have continuously pushed each other to innovate, leading to safer defaults like stopping install scripts by default.
    
    
  • Major independent, venture-backed runtimes are now housed inside broader platform companies (with Bun joining Anthropic and Deno moving to Cloudflare).
    
    
• Conclusion: Even when alternative runtimes or tools don't win the market outright, their pioneering ideas typically survive and are adopted by the broader ecosystem, benefiting all JavaScript developers.
