JS SDK: stopped collecting screen resolution and locale by default

[MaxShehovtsov]

To enable the collection please use telemetry initializers. This code needs to be in your snippet right after the initialization and before appInsights.trackPageView(...):

    appInsights.queue.push(function () {
        appInsights.context.addTelemetryInitializer(function (envelope) {
            envelope.tags = envelope.tags || {};
            if (typeof screen !== "undefined") {
                envelope.tags["ai.device.screenResolution"] = screen.width + "X" + screen.height;
                envelope.tags["ai.device.locale"] = navigator.language || navigator.browserLanguage || "unknown";
            }
        });
    });

It was deprecated as a standard dimension in backend.

You can place screen resolution into custom properties of an event:

appInsights.queue.push(function () {
    appInsights.context.addTelemetryInitializer(function (envelope) {
        var telemetryItem = envelope.data.baseData;
        if (typeof screen !== "undefined") {
            telemetryItem.properties = telemetryItem.properties || {};
            telemetryItem.properties["ai.device.screenResolution"] = screen.width + "X" + screen.height;
            telemetryItem.properties["ai.device.locale"] = navigator.language || navigator.browserLanguage || "unknown";
        }
    });
});
