Deno 2 Has a Free Runtime — Node.js Compatibility Without node_modules

Deno 2 Finally Fixed the Compatibility Problem Deno 1 was brilliant but impractical. You could not use npm packages. The ecosystem was tiny. Nobody shipped production apps on it. Deno 2 changed everything. Full npm compatibility. node_modules support. Drop-in Node.js replacement. What Deno 2 Gives You Native TypeScript # No tsconfig. No ts-node. No build step. deno run app.ts TypeScript just works. Always has in Deno. npm Packages Work import express from ' npm:express ' const app = express () app . get ( ' / ' , ( req , res ) => res . send ( ' Hello from Deno! ' )) app . listen ( 3000 ) Prefix with npm: and it works. No npm install . No node_modules folder (unless you want one). Built-in Tools deno fmt # Format (like Prettier) deno lint # Lint (like ESLint) deno test # Test runner (like Jest) deno bench # Benchmarks deno compile # Compile to single binary deno jupyter # Jupyter notebook kernel deno doc # Generate docs No dev dependencies. No config files. It is all built in. Security
