Typecast properties in object streams

Installation

npm install typepoint

Documentation

// Typepoint requires a `rules` object. Each property in this object is executed
// on the written objects property. Each propery values must be function, there
// return the expected value.
// (e.q. `Number`, is a function there transform '1', to 1)
// The only thing to note, is that `Date` is special since the new operator is
// used here without your involvement. This is because `Date` simply returns a
// string.
// You can also use non-function, they works as constants and overwrites any
// existing or non-existing value.
var conveter = typepoint({id: Number, time: Date, const: 10});

conveter.write({ id: '1', time: 0, other: 'exists'});
conveter.read() // { id: 1, time: new Date(0), other: 'exists', const: 10 };
