Deno Module Cache (~/.deno/deps & ~/.deno/gen)

Space: 500 MB – 5 GB developer Windows, macOS, Linux
Quick Answer: The DENO_DIR folder caches remote TypeScript imports and compiled V8 code bytes. Deleting it is safe.

Bottom Line: It is 100% safe to clear the Deno cache. Deno stores fetched HTTPS TypeScript modules and compiled JavaScript artifacts in DENO_DIR.

What is the Deno Directory Cache?

Located at ~/.deno/ (or %LocalAppData%\deno), Deno manages two main cache subdirectories:

  • deps/: Downloaded remote HTTP/HTTPS modules.
  • gen/: Compiled V8 JavaScript & WebAssembly bytecode.

Can You Delete the Deno Cache?

✅ Yes, safe to delete.

  • Deno will re-fetch remote URL imports automatically when running deno run.
