npm-explain - Explain installed packages Synopsis npm explain <folder | specifier> alias: why Description This command will print the chain of dependencies causing a given pack- age to be installed in the current project. Positional arguments can be either folders within node_modules, or name@version-range specifiers, which will select the dependency rela- tionships to explain. For example, running npm explain glob within npm's source tree will show: glob@7.1.6 node_modules/glob glob@"^7.1.4" from the root project glob@7.1.1 dev node_modules/tacks/node_modules/glob glob@"^7.0.5" from rimraf@2.6.2 node_modules/tacks/node_modules/rimraf rimraf@"^2.6.2" from tacks@1.3.0 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 con- flicting version requirements within the project. $ npm explain node_modules/nyc/node_modules/find-up find-up@3.0.0 dev node_modules/nyc/node_modules/find-up find-up@"^3.0.0" from nyc@14.1.1 node_modules/nyc nyc@"^14.1.1" from tap@14.10.8 node_modules/tap dev tap@"^14.10.8" from the root project Configuration json o Default: false o Type: Boolean Whether or not to output JSON data, rather than the normal output. o In npm pkg set it enables parsing set values with JSON.parse() before saving them to your package.json. Not supported by all npm commands. workspace o Default: o Type: String (can be set multiple times) Enable running a command in the context of the configured workspaces of the current project while filtering by running only the workspaces defined by this configuration option. Valid values for the workspace config are either: o Workspace names o Path to a workspace directory o Path to a parent workspace directory (will result in selecting all workspaces within that folder) When set for the npm init command, this may be set to the folder of a workspace which does not yet exist, to create the folder and set it up as a brand new workspace within the project. This value is not exported to the environment for child processes. See Also o npm help config o npm help npmrc o npm help folders o npm help ls o npm help install o npm help link o npm help prune o npm help outdated o npm help update
