Notifications

The Notifications API is accessible through the io.notifications object.

To specify global notification settings at runtime, use the configure() method. It accepts a Configuration object as an argument with the following properties:

The placement object has the following properties:

The sourceFilter object has the following properties:

The toasts object has the following properties:

To disable all notifications:

const config = { enable: false };

await io.notifications.configure(config);

To disable only toast notifications:

const config = { enableToasts: false };

await io.notifications.configure(config);

To set the position of the Notification Panel and the notification toasts on the screen:

const config = {
    placement: {
        panel: "left",
        toasts: "top-left"
    }
};

await io.notifications.configure(config);

To retrieve the current global notification settings, use the getConfiguration() method:

const config = await io.notifications.getConfiguration();

To raise a notification from your app, use the raise() method of the API. The method accepts as an argument a required IOConnectNotificationOptions object with settings for the notification you want to raise:

const options = {
    title: "New Trade",
    body: "VOD.L: 23 shares sold @ $212.03",
    actions: [
        {
            action: "openClientPortfolio",
            title: "Open Portfolio"
        }
    ]
};

// Raising a notification.
const notification = await io.notifications.raise(options);

Notification Options

The IOConnectNotificationOptions object extends the standard web NotificationOptions object with several additional properties:

Standard Click Handler

The raise() method resolves with a Notification object. Use its onclick property to specify a callback that will be invoked when the user clicks on the notification:

const options = {
    title: "New Trade",
    body: "VOD.L: 23 shares sold @ $212.03",
    actions: [
        {
            action: "openClientPortfolio",
            title: "Open Portfolio"
        }
    ]
};

const notification = await io.notifications.raise(options);

notification.onclick = () => console.log("Notification was clicked.");

Interop Click Handler

You can also use the clickInterop property of the IOConnectNotificationOptions object to specify an Interop method that will be invoked when the user clicks on the notification. For instance, another app has registered an Interop method:

const methodName = "HandleNotificationClick";
const handler = args => console.log(args);

await io.interop.register(methodName, handler);

To invoke this Interop method for handling the notification click, define an InteropActionSettings object and assign it as a value to the clickInterop property of the notification options object:

const interopSettings = {
    // The only required property is the method name.
    method: "HandleNotificationClick",
    arguments: {
        name: "Vernon Mullen",
        id: "1"
    }
};

const options = {
    title: "New Trade",
    body: "VOD.L: 23 shares sold @ $212.03",
    actions: [
        {
            action: "openClientPortfolio",
            title: "Open Portfolio"
        }
    ],
    clickInterop: interopSettings
};

const notification = await io.notifications.raise(options);

You can create action buttons for the notification. When the user clicks on an action button, the specified callbacks will be invoked.

To define action buttons, use the actions property of the IOConnectNotificationOptions object when creating a notification. The actions property accepts an array of NotificationAction objects:

const options = {
    title: "New Trade",
    body: "VOD.L: 23 shares sold @ $212.03",
    actions: [
        {
            action: "callClient",
            title: "Call Client"
        },
        {
            action: "openClientPortfolio",
            title: "Open Portfolio"
        }
    ]
};

⚠️ Note that the action buttons in an io.Connect Notification are limited to two, as the web browsers currently support a maximum of two actions.

Standard Actions

Besides all properties of a standard web Notification object, the Notification object has an additional onaction property. You can use this property to assign a callback that will be invoked when the user clicks an action button in the notification. The callback receives as an argument an ActionEvent object which extends the standard web Event object. The ActionEvent object has an action property that holds the name of the triggered action.

const notificationOptions = {
    title: "New Trade",
    body: "VOD.L: 23 shares sold @ $212.03",
    actions: [
        {
            action: "openClientPortfolio",
            title: "Open Portfolio"
        }
    ]
};

const notification = await io.notifications.raise(notificationOptions);

notification.onaction = function (actionEvent) {
    if (actionEvent.action === "openClientPortfolio") {
        console.log(`Action button in notification "${this.title}" has been clicked.`);
    };
};

Interop Actions

The NotificationAction object provides an interop property which you can use to invoke Interop methods when the user clicks an action button in the notification.

First, register an Interop method in another app:

const methodName = "HandleNotificationClick";
const handler = args => console.log(args);

await io.interop.register(methodName, handler);

After that, in your app define an InteropActionSettings object and assign it as a value to the interop property of the action object in the actions array:

const interopSettings = {
    // The only required property is the method name.
    method: "HandleNotificationClick",
    arguments: {
        name: "Vernon Mullen",
        id: "1"
    }
};

const notificationOptions = {
    title: "New Trade",
    body: "VOD.L: 23 shares sold @ $212.03",
    actions: [
        {
            action: "openClientPortfolio",
            title: "Open Portfolio",
            interop: interopSettings
        }
    ]
};

const notification = await io.notifications.raise(notificationOptions);

To retrieve a list of all available notifications, use the list() method:

const allNotifications = await io.notifications.list();

To clear all notifications, use the clearAll() method:

await io.notifications.clearAll();

To clear a specific notification, use the clear() method and pass the ID of the notification to clear:

await io.notifications.clear(notification.id);

To clear all notifications seen by the user, use the clearOld() method:

await io.notifications.clearOld();

To click a notification or a notification action programmatically, use the click() method and pass either only the notification ID, or the notification ID and the name of the action to click:

const id = notification.id;
const action = "openClientPortfolio";

// Clicking a notification.
await io.notifications.click(id);

// Clicking a notification action.
await io.notifications.click(id, action);

Available since io.Connect Desktop 9.3

The click() method accepts a ClickOptions object as a third argument:

const id = notification.id;
// The notification will be closed when clicked.
const options = { close: true };

await io.notifications.click(id, null, options);

The ClickOptions object has the following properties:

Available since io.Connect Desktop 9.3

To snooze notifications programmatically, use the snooze() method and pass as required arguments the ID of the notification to snooze and the duration in milliseconds for which to snooze it:

io.notifications.snooze(notification.id, 60000);

Available since io.Connect Desktop 9.1

To update the arbitrary data associated with the notification which is available in its data property, use the updateData() method and provide the ID of the notification and the new data:

const id = notification.id;
const data = { io: 42 };

await io.notifications.updateData(id, data);

Notifications can have the following states describing their lifetime:

To set the state of a notification, use the setState() method. To retrieve the state of a notification, use the state property of the Notification object:

const id = notification.id;
const state = "Acknowledged";

// Setting the notification state.
await io.notifications.setState(id, state);

// Retrieving the notification state.
const notificationState = notification.state;

console.log(`Notification with ID "${id}" is in state "${notificationState}".`);

Notifications can be filtered programmatically based on lists of allowed and blocked apps.

To set a notification filter, use the setFilter() method and pass a NotificationFilter object as an argument:

const filter = {
    allowed: ["*"],
    blocked: ["app-one", "app-two"]
};

await io.notifications.setFilter(filter);

The NotificationFilter object has the following properties:

Using a combination of both lists enables you to create various filters:

// Allows all apps to raise notifications.
const allowAll = {
    allowed: ["*"]
};

// Allows only the specified apps to raise notifications.
const allowOnly = {
    allowed: ["app-one", "app-two"]
};

// Allows all except the blocked apps to raise notifications.
const allowAllExcept = {
    allowed: ["*"],
    blocked: ["app-one", "app-two"]
};

// Blocks all apps from raising notifications.
const blockAll = {
    blocked: ["*"]
};

To get the current notification filter, use the getFilter() method:

const filter = await io.notifications.getFilter();

The Notifications API provides methods for subscribing for notification events. All methods return a function you can use to unsubscribe from the respective event.

To get notified when a notification is raised, use the onRaised() method:

const handler = notification => console.log(`Notification with ID "${notification.id}" was raised.`);

const unsubscribe = io.notifications.onRaised(handler);

To get notified when a notification is closed, use the onClosed() method:

const handler = notification => console.log(`Notification with ID "${notification.id}" was closed.`);

io.notifications.onClosed(handler);

To get notified when the state of a notification is changed, use the onStateChanged() method:

const handler = notification => console.log(`The state of notification with ID "${notification.id}" was changed.`);

io.notifications.onStateChanged(handler);

To get notified when the number of active notifications changes, use the onCounterChanged() method:

const handler = info => console.log(`Notifications with state "Active": ${info.count}.`);

io.notifications.onCounterChanged(handler);

To get notified when the global notification settings change, use the onConfigurationChanged() method:

const handler = config => console.log(`Notification settings updated: ${config}.`);

io.notifications.onConfigurationChanged(handler);

Available since io.Connect Desktop 9.1

To get notified when the data property of a notification is updated, use the onDataChanged() method:

const handler = data => console.log(`Notification data: ${data}`);

io.notifications.onDataChanged(handler);

The Notification Panel can be controlled programmatically - show, hide or toggle its visibility. The Notification Panel API is accessible through the io.notifications.panel object.

Operations

To check whether the Notification Panel is visible, use the isVisible() method:

const isPanelVisible = await io.notifications.panel.isVisible();

To show the Notification Panel, use the show() method:

await io.notifications.panel.show();

To hide the Notification Panel, use the hide() method:

await io.notifications.panel.hide();

To toggle the visibility of the Notification Panel, use the toggle() method:

await io.notifications.panel.toggle();

Events

To get notified when the visibility of the Notification Panel changes, use the onVisibilityChanged() method:

io.notifications.panel.onVisibilityChanged(isVisible => console.log(`The Notification Panel is ${isVisible ? "visible": "hidden"}.`));
