constiframessa=require('iframessa');iframessa.getter('userName',({ data, sender})=>{return'Matheus Cristian';});

2. Call the getter on your child window

constiframessa=require('iframessa');iframessa.register('about');iframessa.get('userName').then(({ data, sender})=>{console.log(data);// Matheus Cristianconsole.log(sender);// parent object},data);

Case 2: You would like to emit an event with a data from your child window to your parent

1. Emit a message to your parent window from your iframe

constiframessa=require('iframessa');iframessa.emit('action','logout');
