Would you use NPM (not Yarn or PNPM) in Sep 2020?

AFAIK, NPM has not fixed some serious inconsistencies, namely scripts.preinstall and engineStrict.

  "scripts": {
    "preinstall": "echo 'going to install'"
  "engines": {
    "node": "12.x",
    "yarn": "please-use-pnpm",
    "npm": "please-use-yarn",
    "pnpm": "please-use-yarn"
  "engineStrict": true
Enter fullscreen mode Exit fullscreen mode

About engineStrict, the fix is as easy as echo 'engine-strict=true' > .npmrc, but committing .npmrc to GitHub will cause GitGuardian errors.

About preinstall, it is near perfect for first installs, but...


PNPM is another big topic. Many modules does not play well with symlinks, even with echo 'shamefully-hoist=true' > .npmrc.

Lately, I also have one annoying error with PNPM and @vue/cli.

And, creating local *.d.ts doesn't help (so, it is not about symlinks?); but changing to Yarn helps.


I also see that there is Yarn version 2, which still should only be enabled on per project basis.

But I cannot use it with Vue CLI...

Still, I believe that Yarn is currently the best bet. Not only for features and speed, but also for official supports.

Wait... to install node modules with sudo...?
