Question

I'm trying to use Cordova app insights plugin on my android app and I'm having a problem with the appInsights object on JavaScript. After installing the sample app in the github repository at https://github.com/MSOpenTech/cordova-plugin-ms-appinsights the appInsights object was defined and working, but when I took the exact same steps described in the readme in my application, I got an error "appInsights object undefined".
I reviewed the code in the sample app and noticed that the appInsights object is a global object, but I couldn't find where this object was initialized.
When I tried to use that object on my app the error occurred.
How can I initialize the global object manually or make it work on my app?
Thanks in advance

Refer to the sample at the index.js of https://github.com/MSOpenTech/cordova-plugin-ms-appinsights/blob/master/sample/js/index.js, I tried to put the sample code at https://github.com/MSOpenTech/cordova-plugin-ms-appinsights#sample-usage into the bindEvents function closure, and it worked fine without the "appInsights object undefined" error.
About the appInsights initialization, I dived into plugin file at /plugins/cordova-plugin-ms-appinsights/www/AppInsights.lib.js, format the code and found the function to initialize appInsights:
function initializeAppInsights() {
var n, r;
if (typeof window != "undefined" && typeof JSON != "undefined")
if (n = "appInsights", window[n] === undefined) Microsoft.ApplicationInsights.AppInsights.defaultConfig = Microsoft.ApplicationInsights.Initialization.getDefaultConfig();
else {
var u = window[n] || {},
t = new Microsoft.ApplicationInsights.Initialization(u),
i = t.loadAppInsights();
for (r in i) u[r] = i[r];
t.emptyQueue();
t.pollInteralLogs(i)
}
}
And at the end of the file, it invokes the function as
initializeAppInsights();
So if you need to manually initialize the object, you can try to remove the initializeAppInsights(); at AppInsights.lib.js file and invoke initializeAppInsights() at the place you want. For example in my test:
var app = {
// Application Constructor
initialize: function () {
initializeAppInsights();
document.addEventListener('deviceready', function () {
app.bindEvents();
app.onDeviceReady();
});
},
...
}
