Info Panel

An interactive map application contains an info panel component, which is used to display additional content related to a specific geographical coordinate/location or map element, such as a selected marker or polygon. An info panel contains built-in view sections for basic weather information like observations and forecasts, but is fully extensible so you can provide your own views and content as needed.

The following options are supported when configuring your InfoPanel instance:

Option Type Description Default
views object An object containing the view configurations keyed by view identifier. Content views contain one or more view sections and are used when displaying content within an info panel. An info panel will display a single content view at once. See the Content View Configuration section below for more information.
sections object An object containing the view section configurations keyed by section identifier. View sections represent data for a single data type and are used within content views when rendering an info panel’s content. See the View Section Configuration section below for more information.
title string Label title for the panel. The title is only rendered if the panel is toggleable and in the expanded state.
className string A CSS class name to add to the panel, which can be used for additional style customizations.
toggleable boolean A boolean value indicating whether the panel is toggleable. A toggleable panel will display a button in the closed/collapsed state initially. Clicking on the button will expand the panel to its full size. false
icon string Icon HTML to display in the button when the panel is collapsed. This value can be any valid HTML, including an <img> or <svg> element.
position object Options to configure the position of the panel within its parent container. string The position to pin the panel to relative to its parent container. Supports topleft, top, topright, left, center, right, bottomleft, bottom, or bottomleft.
position.translate IPoint Amount to translate the panel in the x and y axis relative to its pinned position. { x: 0, y: 0 }

Content View Configuration

Content views contain one or more view sections and are used when displaying content within an info panel. The following options define the configuration for a content view:

Option Type Description Default
views object[] An array of view section configurations or view section keys to render as part of this content view. The order in which they appear in the array is the order in which the will be rendered in the info panel. See the View Section Configuration section below for more information.
data object xxxxx
request ApiRequest or Function The ApiRequest to use when loading data for this content view. The request should load all data that is required by all view sections. This value can either be a request instance or a function that configures and returns a request instance.

View Section Configuration

View sections represent data for a single data type and are used within content views when rendering an info panel’s content. The following options define the configuration for a view section:

Option Type Description Default
title string View title. If provided, the title will be rendered at the top of the view section’s container.
data object or Function The data to use when rendering the view section. If a function is provided, the full data set from the parent content view will be passed as an argument and the function must return the specific data required for rendering this view section.
renderer string or Function The section renderer, which can either be an HTML string or a function that receives the view’s data as an argument and returns the final HTML for the view.

Default Configuration

The following is the default configuration object for a InfoPanel instance:

    views: undefined,
    sections: undefined

Also review the default configuration for an InteractiveMapApp instance that is applied to its internal info panel.

Built-in View Sections

A series of view sections are already setup and configured for you for basic weather information, like observations, advisories, forecasts and threats. The following view sections can be used within your own content view configurations:

Key Description
place Displays the formatted place name.
obs Displays the latest observation information for the place.
forecast Displays either an hourly or daily forecast for the place.
alerts Displays the currently active weather alerts for the place.
threats Displays the current weather threats for the place.
outlook Displays a short-term outlook phase for the place.
hazards Displays a series of weather hazard and their impacts for the place.

As an example, the following is the configuration for the built-in place view section:

    data: (data: any): any => {
        if (!data) return null;
        data = data.places || data;
    renderer: (data: any): string => {
        if (!data) return null;
        return (`
            <div class="place">
                <p class="name">${}${!isEmpty(data.state) ? `, ${data.state}` : ''}, ${}</p>

In the above place view section, the data property receives the full data set from the parent content view and returns just the data required for the view. The renderer function then receives this filtered data and outputs the final HTML snippet for this view section within the context of the parent content view.

Note that if a view section’s data function returns null or undefined, then that view section will not be rendered within the parent content view.{{//alert-info}}

Using Content Views

Since an info panel’s content view consists of one or more view sections, you can piece together your content views using the above built-in view sections, your custom view sections, or a combination of both. Simply provide your custom section and content view configurations within the sections and views properties of your info panel’s main configuration object.

An InteractiveMapApp instance also configures a default local weather content view that can be used for displaying weather information for a single location or coordinate.

Configuring a Content View

The following is the views configuration containing the general local weather content view that’s built into InteractiveMapApp for displaying local weather information for a particular location:

    views: {
        localweather: {
            request: () => {
                // main batch request instance
                const request = aeris.api();

                // add a request for all data we need for each section in the content view
                const forecastFields = 'timestamp,tempF,icon,weatherPrimary,windSpeedMPH,windSpeedMinMPH,windSpeedMaxMPH,windGustMPH,snowIN,precipIN'.split(',').map((key) => `periods.${key}`);


                return request;
            views: [{
                renderer: 'place'
                title: 'Active Threats',
                renderer: 'threats'
                title: 'Active Alerts',
                renderer: 'alerts'
                title: 'Impacts',
                renderer: 'hazards'
                title: 'Observations',
                renderer: 'obs'
                title: 'Outlook',
                renderer: 'outlook'
                title: 'Short-Term Forecast',
                renderer: 'forecast'

As demonstrated in the above example, when configuring a content view you must provide an array of view sections to display and either the request to use for the view’s data or the static data to use when rendering the view. This local weather content view uses all of the built-in view sections that come with the SDK, so the renderer property values are just the view section keys documented above.

Refer to our examples section for more examples of creating custom section and content views for your info panel.

Showing Info Panel Content

Once you’ve configured your info panel’s section and content views, you can show your map application’s info panel using one of the configured content views easily using the showInfo() or showInfoAtCoord() method on your interactive map app instance.

At minimum, both methods require the content view key to render when showing the info panel. You can also provide a title to display in the title bar of the info panel and/or the static data to use when rendering the content view.

For instance, to show the built-in local weather content view for the coordinate where the map is clicked with a title of “Local Weather”:'click', (e) => {
    // the coordinate where the map was clicked is stored in the event
    // data, ''
    app.showInfoAtCoord(, 'localweather', 'Local Weather');

The data will automatically be requested using the specified coordinate and the request configured for the content view.

If you’re displaying content for a specific geographical coordinate, use showInfoAtCoord(). This method will automatically perform the configured request using the coordinate provided when called. However, if your content view needs to pass request parameters other than just the coordinate when loading its required data, use showInfo(). When using showInfo(), the associated info panel instance is returned and you are required to call load() with any request parameters your content view’s request requires.

For example, if we’ve added a custom airports vector source to the map to display the current flight rules at major airports, we’d want to display additional information for an airport when clicking its marker on the map. We would then configure our info panel with a custom airport content view to use when an airport is selected. Since this related to airports and not a coordinate, we need to pass the airport code to the content view’s request using showInfo() and then calling load():'marker:click', (e) => {
    const data = || {};

    // check the source key that triggered the click event to make sure
    // we're only showing the info panel for airport markers
    const source = data.awxjs_source;
    if (source === 'airports') {
        const id =;
        const place = || {};
        const name = aeris.utils.strings.toName(;
        app.showInfo('airport', `${id} - ${name}`).load({ p: id });

In this example, the info panel will be shown and rendered immediately with the airport ICAO code and name displayed in the title bar. Instead of the airport content view being rendered at first, a loading indicator is displayed while the request for data is being made via our call to load(). Once data has loaded, the airport content view is rendered with the data and the info panel updates its content.

Refer to our examples section for complete examples of creating and working with custom content views.
