tomevault-io Deno
Deno v2.0 (2024/2025) focuses on Node.js Compatibility. It can now run most npm packages and package.json projects, removing the biggest barrier to entry.
When to Use
- Security: Sandbox by default. No file/net access unless explicitly allowed.
- All-in-One: Built-in linter, formatter, test runner, bundler.
- TypeScript: Native support. No config needed.
Core Concepts
Permission Model
deno run --allow-net --allow-read main.ts.
URL Imports (Legacy-ish)
import ... from "https://deno.land/...". v2 supports npm specifiers too.
Deno Deploy
The global edge network designed for Deno.
Best Practices (2025)
Do:
- Use
jsr: The new JavaScript Registry (superset of npm). - Use
deno serve: High-performance HTTP server. - Migrate Node apps: Try running
deno run main.json existing Node projects.
Don't:
- Don't rely heavily on
node_modules: Use native Deno/JSR patterns where possible for speed.
