Automatically Remove Unused Node Modules with Python

Jeremy Gollehon — Fri, 19 Nov 2021 20:12:00 +0000

We keep a directory under the root of our projects called _dev_tools.

It consists of Python scripts we can quickly run, usually by pressing the Play button of the Code Runner extension in VS Code, to help with project management.

The key is creating tools that work cross-platform on Windows, Mac, and Linux.

Here's our script for removing unused node modules.

import json
from sys import platform
from subprocess import run

div = "=================================="
use_shell = platform == "win32"

print(f"\nFinding unused dependencies\n{div}\n")

cmd = ["npx", "depcheck", "--json"]
depcheck_result = run(cmd, shell=use_shell, capture_output=True, text=True)

unused_dependencies = json.loads(depcheck_result.stdout)["dependencies"]
if len(unused_dependencies) > 0:
    print(f"Found these unused dependencies\n{div}")
    print(*unused_dependencies, sep="\n")

    affirmative_responses = {"y", "yes", "Y", "YES", ""}
    response = input(f"{div}\n\nRemove all? [yes] ").lower() in affirmative_responses

    if response == True:
        cmd = ["yarn", "remove", *unused_dependencies]
        run(cmd, shell=use_shell)

    print(f"\nDone!\n{div}\n")

else:
    print(f"\nDone! - No unused dependencies found.\n{div}\n")

Is anyone using `Yarn 2`?

With the release of NMP 7 today I'm curious if anyone is using Yarn 2? I tried moving a couple projects to Yarn 2 but had even when using nodeLinker: node-modules to keep things relatively similar to Yarn Classic.

When searching for tutorials there are pretty much none.
There are only 14 Questions with the yarn-v2 tag on stackoverflow.

There are seemingly a ton of benefits to Yarn 2 but maybe the differences are too hard to overcome?

It also doesn't help that React Native isn't close to working with the new PnP features.

Anyway... just curious if anyone is using Yarn 2 yet!

Thanks.
