NOTE: It will completely override defaults

Supported Properties

homepage        => str(url)
repository      => str
latest          => semver
name            => str

const pkginfo = require('@ma.vu/pkginfo')

info('got', [
  'name',
  'description',
  'author',
  'dependencies',
  'devDependencies',
]).then(data => console.log(data))
/*

     name: 'got',
     description: 'Simplified HTTP request
     author: 'sindresorhus',
     dependencies: 11,
     devDependencies: 16
   }
*/

Require Exact version

It accepts object, and exact version of package you fetching, and now version is your version you fetching, and latest is latest available version

const pkginfo = require('@ma.vu/pkginfo')

info({ name: 'got', version: '3.0.0' }, [
  'name',
  'version',
  'latest',
  'dependencies',
  'devDependencies',
]).then(data => console.log(data))
/*
   {
     name: 'got',
     version: '3.0.0',
     latest: 9.6.0,
     dependencies: 10,
     devDependencies: 5
   }
*/

Null for not finding package or/and version

Rationale for this is, if you query db and query can't yield the result, you will get null, error will not be thrown. The same is for version

info('not-existing-package-name').then(data => console.log(data))
/* 
   null
*/

Version does not exists

info({name: 'react', version: '100.0.0'}).then(data => console.log(data))
/* 
   null
*/
