Details
----
Run this in a directory with a `package.json`, and it will take all the `dependencies`,
`devDependencies`, and `optionalDependencies`, then `npm install` each one in a temporary
directory with a temporary cache, then measure the install times. Each dependency is then listed
from slowest to fastest.
In addition to the install time, the size on disk and the total number of transitive dependencies are also printed.
Note that this doesn't measure the cost of npm de-duplicating the sub-dependencies;
it only measures the time for installing each dependency independently. So the "total time" and "total size"
are both just rough estimates, as are the per-package times, because you may have packages with many common
dependencies that would therefore get de-duped.
It's also worth noting that because this tool creates a temporary npm cache while it works,
you'll be seeing the _uncached_ time for each package. Therefore your actual `npm install` should run a bit faster,
assuming everything is cached.
Options
----
```
Usage: slow-deps [options]
Options:
--production, --prod Skip devDependencies [boolean]
--no-optional Skip optionalDependencies [boolean]
--no-shrinkwrap Ignore npm-shrinkwrap.json [boolean]
-h, --help Show help [boolean]
Examples:
slow-deps measure all deps in the current project
slow-deps --production --no-optional skip both optional and dev dependencies
```
