Look forward to your more advice.

passing the save option to reify will cause the package-lock and lockfile to be written (defaults to true). This is at the bottom of the usage example.

integrity in the package manifest that pacote downloads for a given package, arborist adds this to the lock automatically.

$ npm view lodash dist
{
  integrity: 'sha512-v2kDEe57lecTulaDIuNTPy3Ry4gLGJ6Z1O3vE1krgXZNrsQ+LFTGHVxVjcXPs17LhbZVGedAJv8XZ1tvj5FvSg==',
  shasum: '679591c564c3bffaae8454cf0b3df370c3d6911c',
  tarball: 'https://registry.npmjs.org/lodash/-/lodash-4.17.21.tgz',

thanks for reply,i found a example in https://github.com/npm/cli/blob/9dc69830a5d78aa4042746d54e2a6b0d2af70caa/workspaces/arborist/lib/arborist/reify.js#L1524-L1529 here.

and integrity found in arborist nodes, it's hard to found beacause mixin cause some properties become prototype of object.after reading documents of arborist,it's clear.
