deparser

deparser

Parse package manager lock files (for now yarn.lock) to generate dependency graph.

Usage

Import Deparser library into your code, and then instantiate with path to package.json and yarn.lock. Start using the methods on your instance.

const Deparser = require('Deparser');
const deparser = new Deparser();

const dependencyTree = deparser.getDependencyTree();
const directDependencies = deparser.getDirectDependencies();
const intents = deparser.getAllIntents();

Example

package.json:

{
  "dependencies": {
    "moment": "^2.22.2",
    "react": "^16.4.2"
  },
  "devDependencies": {
    "mocha": "^5.2.0"
  },
  "optionalDependencies": {
    "fsevents": "^1.2.4"
  }
}

yarn.lock:

Result of dependency tree from the above package.json and yarn.lock is tree.json:

[
  {
    "name": "moment",
    "version": "2.22.2",
    "type": "dependencies"
  },
  {
    "name": "react",
    "version": "16.4.2",
    "type": "dependencies",
    "children": [...]
  },
  {
    "name": "mocha",
    "version": "5.2.0",
    "type": "devDependencies",
    "children": [...]
  },
  {
    "name": "fsevents",
    "version": "1.2.4",
    "type": "optionalDependencies",
    "children": [...]
  }
]
