npm-explain

Synopsis

<!-- AUTOGENERATED USAGE DESCRIPTIONS -->

Description

This command will print the chain of dependencies causing a given package
to be installed in the current project.

If one or more package specs are provided, then only packages matching
one of the specifiers will have their relationships explained.

The package spec can also refer to a folder within ./node_modules

For example, running npm explain glob within npm's source tree will show:

[email protected]
node_modules/glob
  glob@"^7.1.4" from the root project
[email protected] dev
node_modules/tacks/node_modules/glob
  glob@"^7.0.5" from [email protected]
  node_modules/tacks/node_modules/rimraf
    rimraf@"^2.6.2" from [email protected]
    node_modules/tacks
      dev tacks@"^1.3.0" from the root project

To explain just the package residing at a specific folder, pass that as the
argument to the command. This can be useful when trying to figure out
exactly why a given dependency is being duplicated to satisfy conflicting
version requirements within the project.

$ npm explain node_modules/nyc/node_modules/find-up
[email protected] dev
node_modules/nyc/node_modules/find-up
  find-up@"^3.0.0" from [email protected]
  node_modules/nyc
    nyc@"^14.1.1" from [email protected]
    node_modules/tap
      dev tap@"^14.10.8" from the root project
