nfo

npm info with inverted args for multiple pkg support

Execute npm info against multiple packages all together. Useful for comparing the same field value across different published packages.

Since it just wraps npm info, it respects your registry config in .npmrc and works with private packages. No special command-line options needed. (It may also be slow for this reason.)

Note that npm info is just an alias for npm view or npm show.

Examples

Get dist-tags of multiple packages in one run:

$ nfo dist-tags yargs @slack/client yarn

yargs
{ latest: '6.5.0', next: '6.3.0-candidate' }

@slack/client
{ latest: '3.7.0', beta: '2.3.0-beta.2' }

yarn
{ latest: '0.18.1', rc: '0.18.0' }

Check published time:

$ nfo time which-module ansi-align

which-module
{ modified: '2016-06-06T05:54:13.093Z',
  created: '2016-06-06T05:54:13.093Z',
  '1.0.0': '2016-06-06T05:54:13.093Z' }

ansi-align
{ modified: '2016-06-06T20:14:39.942Z',
  created: '2016-04-30T17:43:23.016Z',
  '1.0.0': '2016-04-30T17:43:23.016Z',
  '1.1.0': '2016-06-06T20:14:39.942Z' }

Output aggregated results as JSON:

$ nfo dist.tarball standard browserify webpack -j | json
{
  "standard": {
    "field": "dist.tarball",
    "value": "https://registry.npmjs.org/standard/-/standard-8.6.0.tgz"
  },
  "browserify": {
    "field": "dist.tarball",
    "value": "https://registry.npmjs.org/browserify/-/browserify-13.1.1.tgz"
  },
  "webpack": {
    "field": "dist.tarball",
    "value": "https://registry.npmjs.org/webpack/-/webpack-1.14.0.tgz"
  }
}
