Deno for Python
The easiest way to install and use Deno — the modern JavaScript and TypeScript runtime — in your Python projects.
What is Deno?
Deno is a secure runtime for JavaScript and TypeScript that's built on V8, Rust, and Tokio. It features:
- 🔒 Secure by default - No file, network, or environment access unless explicitly enabled
- 🚀 TypeScript support - Built-in TypeScript compiler, no configuration needed
- 📦 Modern module system - Native ES modules with URL imports
- 🛠️ Built-in tooling - Includes formatter, linter, test runner, bundler, and more
- 🌐 Web standard APIs - Compatible with browser APIs like
fetch,WebSocket, andWeb Workers - ⚡ High performance - V8 engine with Rust-powered I/O
Installation
Using pip
pip install deno
Using uv (recommended)
uv add deno
Using poetry
poetry add deno
Usage
Command Line
Run Deno directly using uvx or pipx:
# Check version
uvx deno --version
# Run a script
uvx deno run https://examples.deno.land/hello-world.ts
# Start a REPL
uvx deno
With pipx:
pipx run deno --version
After installing with pip, the deno command is available in your PATH:
deno run --allow-net server.ts
Python API
Use the Python API to integrate Deno into your Python applications:
import deno
import subprocess
# Get the path to the Deno executable
deno_bin = deno.find_deno_bin()
# Run a Deno script from Python
result = subprocess.run(
[deno_bin, "run", "--allow-net", "script.ts"],
capture_output=True,
text=True
)
print(result.stdout)
Example: Running TypeScript from Python
import deno
import subprocess
import tempfile
import os
# Create a temporary TypeScript file
ts_code = """
console.log("Hello from Deno!");
const data = { message: "TypeScript works!" };
console.log(JSON.stringify(data));
"""
with tempfile.NamedTemporaryFile(mode='w', suffix='.ts', delete=False) as f:
f.write(ts_code)
ts_file = f.name
try:
# Execute with Deno
result = subprocess.run(
[deno.find_deno_bin(), "run", ts_file],
capture_output=True,
text=True
)
print(result.stdout)
finally:
os.unlink(ts_file)
