Usage examples

Case 1: You would like to receive the logged user name from your web application into your iframe.

1. Create a getter on your parent window

<iframe src="about.html" name="about"></iframe>

const iframessa = require('iframessa');

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

2. Call the getter on your child window

const iframessa = require('iframessa');

iframessa.register('about');

iframessa.get('userName').then(({ data, sender }) => {
  console.log(data); // Matheus Cristian
  console.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

const iframessa = require('iframessa');

iframessa.emit('action', 'logout');

This will emit a 'action' event to your parent with the data 'logout'. Note that the data can be an object as well.

2. Make your parent watch the 'action' event

const iframessa = require('iframessa');

iframessa.on('action', ({ data, sender }) => {
  console.log(data); // logout
});

You can emit something to a specific child window with iframessa.modules.about.emit(event, data);
