Handling events

Once user grants permission for hosting page to communicate with API TrezorConnect will emits events about device state. Events can be distinguished by "type" field of event object (TODO structure) Constants of all types can be imported from package

ES6

import TrezorConnect, { DEVICE_EVENT, DEVICE } from 'trezor-connect';

TrezorConnect.on(DEVICE_EVENT, (event) => {
    if (event.type === DEVICE.CONNECT) {

    } else if (event.type === DEVICE.DISCONNECT) {

    }
});

CommonJS

var TrezorConnect = require('trezor-connect').default;
var DEVICE_EVENT = require('trezor-connect').DEVICE_EVENT;
var DEVICE = require('trezor-connect').DEVICE;

TrezorConnect.on(DEVICE_EVENT, (event) => {
    if (event.type === DEVICE.CONNECT) {

    } else if (event.type === DEVICE.DISCONNECT) {

    }
});

Inline

window.TrezorConnect.on('DEVICE_EVENT', (event) => {
    if (event.type === 'device-connect') {

    } else if (event.type === 'device-disconnect') {

    }
});
