Package Jason

Do you want to see the package dependency tree? Ask Jason, he knows everything about the package.json files!

Package Jason is a tool that scan recursively all dependencies of a given package and generate a tree that shows all nested dependencies.

For example, let's scan react package:

const packageJason = require("package-jason");
const result = await packageJason("react");

We will get a JSON tree and meta data about the packages scanned:

• total: total number of packages found during the scanning process
• count: number of unique packages found (because the same package can be included by several sub-dependencies)

{
  "tree": {
    "name": "react",
    "version": "16.5.2",
    "children": [
      {
        "name": "loose-envify",
        "version": "1.4.0",
        "children": [
          {
            "name": "js-tokens",
            "version": "4.0.0"
          }
        ]
      },
      {
        "name": "object-assign",
        "version": "4.1.1"
      },
      {
