dependencies-tree

Collect dependencies from package.json

Install

npm i dependencies-tree

Usage

import getDependencies from 'dependencies-tree'

const { tree, flat } = await getDependencies()

API (Define)

export interface DependenciesOptions {
  /** @default process.cwd() */
  root?: string
  /** `dependencies` in package.json under the default root path */
  dependencies?: string[]
}

Example

Assume there is a dependency electron-squirrel-startup in package.json.

{
  "dependencies": {
    "electron-squirrel-startup": "^1.0.0"
  }
}

We get the dependency tree based on the path where package.json is located.

import getDependencies from 'dependencies-tree'

const root = process.cwd()
const { tree } = await getDependencies({ root })

console.log(tree)

[
  {
    name: 'electron-squirrel-startup',
    path: {
      src: path.join(fixtureRoot, 'node_modules', 'electron-squirrel-startup'),
      dest: path.join('node_modules', 'electron-squirrel-startup'),
      name: 'electron-squirrel-startup',
    },
    dependencies: [
      {
        name: 'debug',
        path: {
          src: path.join(fixtureRoot, 'node_modules', 'debug'),
          dest: path.join('node_modules', 'debug'),
          name: 'debug',
        },
        dependencies: [
          {
            name: 'ms',
            path: {
              src: path.join(fixtureRoot, 'node_modules', 'ms'),
              dest: path.join('node_modules', 'ms'),
              name: 'ms',
            },
            dependencies: [],
          },
        ],
      },
    ],
  },
]

Get the flat dependency tree

import getDependencies from 'dependencies-tree'

const root = process.cwd()
const { flat } = await getDependencies({ root })

console.log(falg)

// ↓↓↓↓

[
  {
    src: path.join(fixtureRoot, 'node_modules', 'electron-squirrel-startup'),
    dest: path.join('node_modules', 'electron-squirrel-startup'),
    name: 'electron-squirrel-startup',
  },
  {
    src: path.join(fixtureRoot, 'node_modules', 'debug'),
    dest: path.join('node_modules', 'debug'),
    name: 'debug',
  },
  {
    src: path.join(fixtureRoot, 'node_modules', 'ms'),
    dest: path.join('node_modules', 'ms'),
    name: 'ms',
  },
