Validate parameters from an object (such as express's req.query) and return any errors based on a schema defined.
npm install acceptance
Any parameters not defined in the schema will be discarded in the output a.accepted
var accept = require('acceptance').accept;
var schema = {
name: {
required: true,
validation: { regex: /^[a-zA-Z0-9] $/, message: 'Not alpha numeric' }
},
phone: {
required: false,
validation: { regex: /^-?[0-9] $/, message: 'Not a valid integer' }
},
location: {
required: true,
validation: false
}
}
var params = { name: 'bradley', phone: '012345hello', random: 'a random param' };
var a = accept(params, schema);
if(a.errors) {
console.log(a.errors);
}
else {
console.log(a.accepted);
}Will output:
[ { field: 'phone', message: 'Not a valid integer' }, // Invalid match with regex
{ field: 'location', message: 'Missing Field' } ] // Not present in the params givenRun the tests make test
