API

default: dependenciesHierarchy(projectPath, [opts]): Promise<Hierarchy>

Creates a dependency tree for a project's node_modules.

Arguments:

• projectPath - String - The path to the project.
• [opts.depth] - Number - 0 by default. How deep should the node_modules be analyzed.
• [opts.only] - 'dev' | 'prod' - Optional. If set to dev, then only packages from devDependencies are analyzed. If set to prod, then only packages from dependencies are analyzed.

forPackages(packageSelectors, projectPath, [opts]): Promise<Hierarchy>

Creates a dependency tree for a project's node_modules. Limits the results to only the paths to the packages named.

Arguments:

• packageSelectors - (string | {name: string, version: string})[] - An array that consist of package names or package names and version ranges. E.g. ['foo', {name: 'bar', version: '^2.0.0'}].
• projectPath - String - The path to the project
• [opts.depth] - Number - 0 by default. How deep should the node_modules be analyzed.
• [opts.only] - 'dev' | 'prod' - Optional. If set to dev, then only packages from devDependencies are analyzed. If set to prod, then only packages from dependencies are analyzed.
