ICAL bikeshed

ical.js

// some ical string;
var rawIcalString;

// my ical data - remove decorate parameter
var data = ICAL.parse(rawIcalString);

var component = new ICAL.Component(data);

// later I store it in the DB
var structuredCloneData;
var component = new ICAL.Component(structuredCloneData);

// mutate it

component.removeSubcomponent('FOO');
component.addPropertyWithValue('foo', 'bar');

// save it back to db

// this is now undecorated
var storable = component.toJSON();

and natually we can also have

ICAL.stringify(object)

And store objects as raw JSON strings.

var json = JSON.stringify(component);
var component = new ICAL.Component(JSON.parse(json));
