API to walk dependency tree ?

[i386]

Hi there,

I want to write a plugin to walk the dependency tree of a project and generate a special lock file for our platform dependencies,.. Im looking at using a afterAllInstalled hook to do this. However, looking through the API docs I can't seem to find the right APIs to walk the dependency tree of non-dev deps? Can someone give me a pointer or two please?

Cheers
J

You can use the Manifest to get the information of package.json

import { Manifest } from '@yarnpkg/core';

const plugin = {
  hooks: {
    afterAllInstalled: async(project, options) => {
      const manifest = await Manifest.find(project.cwd); // root package.json's information
      console.log(manifest.raw.dependencies); // same as your package.json
      console.log(manifest.dependencies); // after yarn parsing
    },
  }
}

If you want to get the workspaces dependencies,

import { Manifest } from '@yarnpkg/core';
import { PortablePath } from '@yarnpkg/fslib';

const manifest = await Manifest.find(`your/workspace/directory` as PortablePath);
