Readme
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.
