Breaking Changes

⚠️ Note that each breaking change is listed under all libraries it affects.

@interopio/widget

The compact mode for the io.Connect widget has been deprecated.

The mode property of the WidgetConfig object has been deprecated and the WidgetMode interface has been removed from the library types.

The "top", "bottom", "left", and "right" members of the WidgetPosition enumeration have been deprecated and replaced with "top-left", "top-center", "top-right", "center-left", "center-right", "bottom-left", "bottom-center", and "bottom-right".

The default value for the position property of the WidgetConfig object has been changed to "bottom-center" instead of "bottom".

New Features

⚠️ Note that each new feature is listed under all libraries it affects.

@interopio/browser
The following features are now available in the @interopio/browser library:
Refreshing Windows
To refresh a window, use the refresh() method of a WebWindow instance:
await myWindow.refresh();
Zooming
You can now use the zoomIn(), zoomOut(), setZoomFactor(), and onZoomFactorChanged() methods of a WebWindow instance to control window zooming programmatically:
// Retrieves the current zoom factor.
const zoomFactor = myWindow.zoomFactor;

// Increase the zoom factor by one step.
await myWindow.zoomIn();

// Decrease the zoom factor by one step.
await myWindow.zoomOut();

// Set a specific zoom factor.
await myWindow.setZoomFactor(150);

// Get notified when the zoom factor changes.
myWindow.onZoomFactorChanged(console.log);

@interopio/browser-platform
The following features are now available in the @interopio/browser-platform library:
Request Headers for Publishing OpenTelemetry Signals
To specify headers to be added to all HTTP requests sent by io.Connect Browser when publishing OpenTelemetry signals, use the headers property of the otel object in the configuration object for initializing the @interopio/browser-platform library. To specify headers to be added to the HTTP requests sent by io.Connect Browser when publishing metrics, use the headers property of the metrics object under the otel top-level key:
import IOBrowserPlatform from "@interopio/browser-platform";

const config = {
    licenseKey: "my-license-key",
    otel: {
        // Headers that will be sent with every request for publishing OpenTelemetry signals.
        headers: {
            "Custom-Header": "custom-header-value"
        },
        metrics: {
            url: "https://my-metrics-collector.com/metrics",
            // Headers that will be sent with every request for publishing metrics.
            headers: {
                "Custom-Metrics-Header": "custom-header-value"
            }
        }
    }
};

const { io } = await IOBrowserPlatform(config);
Additional OpenTelemetry Attributes
To specify additional resource attributes to be added to all published OpenTelemetry signals, use the additionalResourceAttributes property of the otel object in the configuration object for initializing the @interopio/browser-platform library. To specify additional entity-level attributes to be added to all published OpenTelemetry signals, use the getAdditionalAttributes property of the otel object and provide a function that returns an object with key/value pairs describing the attribute names and values. The additionalResourceAttributes and getAdditionalAttributes properties are also available under the metrics property of the otel object:
import IOBrowserPlatform from "@interopio/browser-platform";

const config = {
    licenseKey: "my-license-key",
    otel: {
        // Resource attributes to be added to all published OpenTelemetry signals.
        additionalResourceAttributes: {
            "resourceAttribute": "custom-value"
        },
        // Entity-level attributes to be added to all published OpenTelemetry signals.
        getAdditionalAttributes: () => { return { "attribute": "custom-value" } },
        metrics: {
            url: "https://my-metrics-collector.com/metrics",
            // Resource attributes to be added to all published metrics.
            additionalResourceAttributes: {
                "resourceAttribute": "custom-value"
            },
            // Entity-level attributes to be added to all published metrics.
            getAdditionalAttributes: () => { return { "attribute": "custom-value" } }
        }
    }
};

const { io } = await IOBrowserPlatform(config);
Caching of App Definitions, Layouts & App Preferences
It's now possible to instruct io.Connect Browser to cache app definitions, Layouts, and app preferences fetched from remote stores. The data will be cached by using the IndexedDB API of the browser. You can also specify whether the platform should wait for an initial response from the remote store before continuing its initialization.
The following example demonstrates how to enable caching of Layouts:
import IOBrowserPlatform from "@interopio/browser-platform";

const config = {
    licenseKey: "my-license-key",
    layouts: {
        mode: "rest",
        rest: {
            url: "https://my-remote-store/layouts",
            cache: {
                // Enabling caching of Layouts. Caching data from remote stores is disabled by default.
                enabled: true
            },
            // It's required to set this when caching is enabled in order to instruct the platform
            // at what interval to poll the remote store for updates.
            // If not set, the platform will fetch the Layout definitions only once on startup.
            pollingInterval: 30000,
            // If `true` (default) the platform will wait for an initial response
            // from the remote store before continuing with its initialization.
            waitInitialResponse: true
        }
    }
};

const { io } = await IOBrowserPlatform(config);
Refreshing Windows

You can now use the refresh() method of a WebWindow instance to refresh a window.

Zooming

You can now use the zoomIn(), zoomOut(), setZoomFactor(), and onZoomFactorChanged() methods of a WebWindow instance to control window zooming programmatically.

@interopio/home-ui-react
The <Launchpad /> component now contains the <LaunchpadContentsContainer />, <LaunchpadHeader />, and <LaunchpadBody /> child components and has the following structure:
<Launchpad>
    <LaunchpadContentsContainer>
        <LaunchpadHeader />
        <LaunchpadBody />
    </LaunchpadContentsContainer>
</Launchpad>
The <LaunchpadContentsContainer /> component accepts the same properties as the <Launchpad /> component and can be used independently of the <Launchpad /> component. Using the <LaunchpadContentsContainer /> component instead of the <Launchpad /> component may be useful if your custom Launchpad implementation requires you to have separate components for the Launchpad header and body.

⚠️ Note that if you want to use the <LaunchpadHeader /> and <LaunchpadBody /> components, they must be wrapped in the <LaunchpadContentsContainer /> component in order to function properly. This is due to the fact that the <LaunchpadContentsContainer /> component contains all required providers for passing information down to the <LaunchpadHeader /> and <LaunchpadBody /> components.

Component Description

<LaunchpadContentsContainer /> Component containing the <LaunchpadHeader /> and <LaunchpadBody /> components. Accepts the same properties as the <Launchpad /> component and can be used instead of it.

<LaunchpadHeader /> Component containing the header area of the Launchpad (search bar and pin icon).

<LaunchpadBody /> Component containing the body of the Launchpad (the list of Launchpad sections and the search results section).

@interopio/ng

Version 5.0 and later of the @interopio/ng library has been verified to offer full support for all Angular versions up to 20, both with standalone components and modules.

Version 6.0 and later of the @interopio/ng library has been verified to offer full support for Angular versions 19 and 20, both with standalone components and modules. Angular versions up to 18 haven't been verified to work with @interopio/ng version 6.0 and won't be supported as Angular support for these versions has either ended or will end soon.

Version 6.0 and later of the @interopio/ng library is specifically designed to support both standalone components and modules. It also provides the provideIoConnect() function for configuring and initializing the @interopio/ng library in Angular apps that use standalone components. The provideIoConnect() function accepts an IOConnectNgSettings object as an optional argument.

⚠️ Note that the provideIoConnect() function is available only in version 6.0 and later of the @interopio/ng library.

The following examples demonstrate using the provideIoConnect() function for configuring and initializing the @interopio/ng library in an Angular Main app that uses standalone components.
In app.config.ts of the Main app:
import { ApplicationConfig } from "@angular/core";
import { provideIoConnect } from "@interopio/ng";
import IOBrowserPlatform, { IOConnectBrowserPlatform } from "@interopio/browser-platform";

// Browser platform configuration.
const config: IOConnectBrowserPlatform.Config = {
    licenseKey: "my-license-key"
};

export const appConfig: ApplicationConfig = {
    providers: [
        // Configuring and initializing the Main app.
        provideIoConnect({
            browserPlatform: {
                factory: IOBrowserPlatform,
                config
            }
        })
    ]
};
In main.ts of the Main app:
import { bootstrapApplication } from "@angular/platform-browser";
import { appConfig } from "./app/app.config";
import { App } from "./app/app";

bootstrapApplication(App, appConfig);
The following examples demonstrate using the provideIoConnect() function for configuring and initializing the @interopio/ng library in an Angular Browser Client app that uses standalone components.
In app.config.ts of the Browser Client app:
import { ApplicationConfig } from "@angular/core";
import { provideIoConnect } from "@interopio/ng";
import IOBrowser, { IOConnectBrowser } from "@interopio/browser";

const config: IOConnectBrowser.Config = {
    // Optional Browser Client configuration.
};

export const appConfig: ApplicationConfig = {
    providers: [
        // Configuring and initializing the Browser Client.
        provideIoConnect({
            browser: {
                factory: IOBrowser,
                config
            }
        })
    ]
};
In main.ts of the Browser Client app:
import { bootstrapApplication } from "@angular/platform-browser";
import { appConfig } from "./app/app.config";
import { App } from "./app/app";

bootstrapApplication(App, appConfig);

@interopio/widget

Placeholders indicating the available docking positions for the io.Connect widget will now appear within the window when the user moves the widget manually.

Additional docking positions are now available for the widget - "top-left", "top-center", "top-right", "center-left", "center-right", "bottom-left", "bottom-center", and "bottom-right".

io.Connect Browser will now remember the last docked position for the widget (per app) and will load the widget in the same position during the next user session. This setting is configurable and can be changed by using the newly added restoreLastKnownPosition property of the WidgetConfig object passed in the configuration object for initializing the @interopio/browser library in Browser Client apps:
import IOBrowser from "@interopio/browser";

const options = {
    widget: {
        enable: true,
        restoreLastKnownPosition: false
    }
};

const io = await IOBrowser(options);
You can now use TAB and SHIFT + TAB to move through the buttons of the widget. Use ENTER or SPACE to open or close the widget context menu. Click outside the widget context menu or use ESC to close it.

The widget now supports directional multiple Channels:
