    selectivepublic

    Select parameters from an object (such as express's req.query) and return any errors based on a specification defined.

    npm install selective

    Append one of the following to each option to specify a requirement for that parameter:

    * Represents an optional parameter.
    # Represents a group (if one field from a group is in req.query then require the entire group).

    var selective = require('selective');
     
    var params = {
      name: 'bradley',
      email: 'bradley@example.com',
      random: 'random param'
    }
     
    selective.select(params, ['#name', '#email', '#password', '*location', 'phone'], function(err, selected){
      if(err) console.log(err)
      else console.log(selected);
    });

    Will output:

    [ { field: 'password', type: 'Missing Field' },  // 'password' is part of a group with a param sent (name).
      { field: 'phone', type: 'Missing Field' },     // 'phone' is a required field.
      { field: 'random', type: 'Invalid Field' } ]   // 'random' is an undefined option.  
      
      // An error was not thrown for location as it is an optional field.
