x ai deno minify js

Yes, Deno can minify your TypeScript/JavaScript code.

How to Minify with Deno

Deno provides built-in minification (powered by esbuild) through its bundling commands:

1. deno bundle --minify

   • Creates a single-file bundle and minifies it.
   • Great for browser or library bundles.

   deno bundle --minify main.ts output.bundle.js
   

2. deno compile --bundle --minify

   • Compiles your code into a standalone executable and minifies the embedded bundle.
   • Reduces both file size and runtime memory usage (useful for CLIs and deployed apps).

   deno compile --bundle --minify --allow-net main.ts
   

Key Options

• --minify — Enables whitespace removal, comment stripping, and basic optimizations.
• --platform browser (or deno) — Useful when targeting the browser.
• --sourcemap — Generate source maps alongside the minified output.

Example from official docs:

# Bundle with minification
deno bundle --minify main.ts

# For executables
deno compile --bundle --minify main.ts

Additional Notes

• Deno’s minifier is fast and handles TypeScript, JSX/TSX, and dependencies (including npm/JSR) out of the box.
• For more advanced needs (e.g., heavy mangling or custom config), you can still pipe the output through tools like Terser.

This is a nice advantage over plain tsc — Deno gives you minification without extra dependencies for many common use cases. Let me know what you're building (web app, CLI, etc.) if you want a more specific command!
