framebus-sw v1.0.1

Framebus-sw

Framebus-sw, a forked project from Framebus 5.1.2, allows you to easily send messages across frames (and iframes) with with either broadcasting to all or only to the especified frame.

Usage references: Framebus (https://github.com/braintree/framebus)

Change

Added broadcastMode to FramebusOptions.

Option broadcastMode decided which window the message will be post to. Options such self, parent, children will verify window origin with target origin before post message, so that can avoid the error throw from postMessage when it does not.

type FramebusOptions = {
  origin?: string, // default: "*"
  broadcastMode?: string, // default "all
  channel?: string, // no default
  verifyDomain?: (url: string) => boolean, // no default
};

If Verify Origin is No, it will throw error to web console when window origin does not match with target origin.

Examples

    const Framebus = require('framebus-sw');

    // default bus instance
    const bus = new Framebus();
    const defaultBus = new Framebus({ broadcastMode: 'all' });

    // bus instance only posts messages to itself
    const selfBus = new Framebus({
        origin: location.origin,
        broadcastMode: 'self'
    });

    // bus instance only posts messages to its verified parent
    const parentBus = new Framebus({
        origin: 'http://parent_origin.com'
        broadcastMode: 'parent'
    });

    // bus instance only posts messages to the verified children
    const childrenBus = new Framebus({
        origin: 'http://children_1.com'
        broadcastMode: 'children'
    });
