npm i --no-cache caches in a false folder of cwd


(Joshua) #1

What I Wanted to Do

Install without using the cache with npm i --no-cache.

What Happened Instead

npm created a false folder in my current directory with the cache data in it.

Reproduction Steps

  1. mkdir test
  2. cd test
  3. npm init -y
  4. npm i --no-cache
  5. ls
  6. See the false folder



{ '21088': '1.0.0',
  npm: '6.1.0',
  ares: '1.14.0',
  cldr: '33.0',
  http_parser: '2.8.0',
  icu: '61.1',
  modules: '64',
  napi: '3',
  nghttp2: '1.29.0',
  node: '10.1.0',
  openssl: '1.1.0h',
  tz: '2018c',
  unicode: '10.0',
  uv: '1.20.2',
  v8: '6.6.346.27-node.6',
  zlib: '1.2.11' }


I’m assuming this is because npm uses the result of config.get('cache') as the cache dir without checking to make sure it’s actually a string.

I’ve been thinking about this recently and what it’d take to support no-cache installs – basically the main stopper right now is git dependencies, which rely on a cache after building the tarballs to re-fetch them. This is a thing they should probably not be doing in the first place, but requires a bit of juggling.

I believe there’s also a few places where a tmp directory is used inside cache to do some operation or another, and those need to be hunted down.

Finally, everything that uses the cache (pacote, make-fetch-happen) need to be aware that a false means to not cache at all, and that might be either very little work, or a lot of work.

In any case, this is definitely a project, and I’d totally take a PR that does this. It’ll probably require touching several different repos, tho.

I’m gonna move this to #ideas because it’s a feature request in disguise.
