weak-type-wizard

A small schema enforcer that attempts to cast the properties of an object to the types you want 'em to be.

A small schema enforcer that attempts to cast the properties of an object to the types you want 'em to be.

Example

var Wizard = require('weak-type-wizard')
 
var cast = new Wizard({
boolean: 'sexy',
number: 'devil',
date: 'Tue May 05 2015 20:51:30 GMT-0500 (CDT)',
string: ['one', 'two', 'cat']
})
 
cast({
sexy: "true",
devil: "667",
one: 1,
two: "200"
}) // => { sexy: true, devil: 667, one: '1', two: '200' } 
 

The "primitive" types of boolean, number, date, and string are supported. You can supply default values, or even add your own types, like so:

 
var wizard = new Wizard({
date: 'dateProperty',
exciting: 'butts',
number: ['someNumber', 'anotherNumber'],
default: {
someNumber: 666,
anotherNumber: '1337'
},
cast: {
exciting: function castToExciting(input) {
return "!" + input + "!"
}
}
})
 

LevelUP support

Use a wizard as a LevelUP encoding - serialize the objects to JSON, and get them back out with all of the parameters cast to whatever you like. Example:

 
var wizard = new Wizard({
date: ['dateProperty'],
number: 'someNumber'
})
 
var db = levelmem('test', {
valueEncoding: wizard.getLevelUpEncoding()
})
