trigger | Superior events for single page web apps | Runtime Evironment library

State of the application:

• A single virtual machine which runs an apache server.
• Application exposed via the virtual machine's public IP (not behind a loadbalancer)

I have an healthprobe endpoint running that needs probed every few seconds to see if the app is up, and trigger an alert in case it is not.

What are my options? I want to get the healthprobe up and running first, before I move to a virtual machine scale set and a load balancer.

I am having trouble tracking down documentation on this, so hoping someone knows as I am not able to get application insights to capture telemetry on starttrackevent and stopstrackevent across pages. This is an asp.net mvc application, so SPA is not in play here.

I am worried I may be doing something incorrectly, however the likely case is it doesn't support it.

Flow:

• user hits site for the first time
• user does action that triggers startTrackEvent("eventName");
• user navigates to a new page
• user does action that triggers stopTrackEvent("eventName");

-- from the appInsights readme https://github.com/microsoft/ApplicationInsights-JS/blob/master/README.md

appInsights.startTrackEvent("event");

appInsights.stopTrackEvent("event", null, {customProp1: "some value"});

Iam using EventChannel to handle events from hardware barcode scanner. EventChannel is initialized in initState, in main class - it works through whole app. While change is detected, it inserts value into global variable (ValueNotifier - i dont know, if it is right) and then I need to work with that value in multiple widgets. I need some sort of widget, which will tell me, that value updated and it will trigger onEvent function - something like RawKeyboardListener. I tried using listeners, but when i do pushNamed, the listener is still listening and it runs code from previous pages, while scanning.

Is there any widget, that would be suitable for me? (cant use ValueListenableBuilder, because it has no "onEvent" function) Or is there any way, to remove and add listeners while moving between pages, or while modal bottom sheet is opened? (I need to access previous listeners, after Navigator.pop)

I need a cloud function that triggers automatically once per day and query in my "users" collection where "watched" field is true and update all of them as false. I get "13:26 error Parsing error: Unexpected token MyFirstRef" this error in my terminal while deploying my function. I am not familiar with js so can anyone please correct function. Thanks.

I receive the error when triggering a cloud function using the gcloud command from terminal:

gcloud functions call function_name

On the cloud function log page no error is shown and the task is finished with no problem, however, after the task is finished this error shows up on the terminal.

gcloud crashed (ReadTimeout): HTTPSConnectionPool(host='cloudfunctions.googleapis.com', port=443): Read timed out. (read timeout=300)

Note: my function time out is set to 540 second and it takes ~320 seconds to finish the job

I want to collect the names (Jenny, Tiffany, etc.) that are stored in every object. and these objects live in an array. I've used Array.prototype.every() and Array.prototype.forEach(), but I don't think they are the right methods.

I also want to note that majority of these codes are from Codaffection. I am practicing on developing in React.

If you would like to experiment with the code, click here.

In every object, there is an id, fullname, email and etc.

This is the code that adds, edits, generates unique ids for each employee, and gets all storage data.

I'm trying to parallelize a merge-sort algorithm. What I'm doing is dividing the input array for each thread, then merging the threads results. The way I'm trying to merge the results is something like this:

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

I have two functions one thats triggered on a mouseenter event and the other on mouseleave. Both of these functions are repeated three times.

On mouseenter the classlist "active" is addded 5x and the text content is changed. On mouseleave the classlist active is removed 5x and the text content is set to an empty string, and the original image is displayed again.

When the mouseenter event listener is triggered, Depending on which image is being hovered (3 images).
the text content property that gets added various between the three "Photosnap" "Dine" "Nike".
As-well as the background color that gets triggered various between "red" "blue" "pink".

Hover state shown as red left image and normal state shown as right image
-The image shown here is one of three. It is displayed with a red background and the text content of "photosnap".
-The other with a blue background and the text content of "Dine".
-The third and final with a pink background and the text content of "Nike".

I hope this paints a clear picture i am having a hard time making this a code snippet.

I am trying to refactor this javascript so its not so repetitive. I'm new to javascript and having a hard time getting this to work as something other than what i currently have. I'm not clear on how to make a function that i can call inside of other functions to cut down on the repeated code. Or possibly use the "this" keyword ?
