I want to load up the view then update the variable data to stop the page taking ages to load (lots of data to load up). Is this possible with Laravel livewire?

I'm trying to get livewire to render the view and then update the public variables after the page has been loaded. In my case, I'll be getting data from an api so I want the user to see the page and then I can add some loading spinners whilst fetching the data.

However, from my test and looking at the livewire lifecycle my test variable doesn't update.

Example Livewire Controller

Seems like a simple requirement, and of course I could maintain my own flag using the lifecycle hooks. See also https://forum.vuejs.org/t/check-if-mounted-was-called/88177/6 for a similar question.

However, I prefer to use something already build-in. I am sure, VueJs maintains the lifecycle state somewhere.

Here's my watcher, simplified:

I am getting unusual behaviour when routing to a page from a side menu placed app.componment. When the page loads data is called from a remote server in ngOnInit()

Description

In the mounted() part of the component I add an event listener, which should call one of the methods.

Code

Angular 10.1.6, TypeScript 4.0.5

Hello

In my webapp, I have 3 components.

Component A stores an Array

I am learning angular.There are a lot of lifecycle methods. For example ngOnChanges runs every time where is new value in the input properties in the child component - that are passed by value.

I don't understand the method - ngAfterContentInit. In angular documentation says :

https://angular.io/guide/lifecycle-hooks

Respond after Angular projects external content into the component's view, or into the view that a directive is in.

But that does'n seem as good explanation. Can somoebody please tell my why we use and to understand better one REAL WOLRD SCENARIO - USE CASE

So I was reading about the component lifecycle hooks and came to know that DoCheck is triggered after every change detection cycle, and is followed by AfterContentChecked and AfterViewChecked. If that is the case, then why is the DoCheck hook needed in the first place?. Everything that we write in the DoCheck method, can be written in the AfterContentChecked or the AfterViewChecked method as well (since they get triggered right after the DoCheck method). And since DoCheck is mostly used for debugging purposes, replacing it with the other these lifecycle hooks won't break anything.

I am currently using Angular 7+ with Highcharts API.

I integrated Highcharts using the following Official Github Link.

There is a callbackFunction in Highcharts which we can use to get the chart instance . However, i am yet to figure out 2 things:

1. When does the actual instance of chart gets created along with the options, like in which lifecycle hook in Angular? Or is it independent of the lifecycle hooks.

2. I saw a developer's example in which he used the callbackFunction while inside the ngOnInit lifecycle hook and it worked ( i.e we got a chart instance from the callback ). However the same did not work for ngOnChanges hook.

   So my point was that, suppose there is an @Input property related to graph data which is to be rendered by the Highcharts.chart ( like say appending a new series ), then i would have to use ngOnChanges method in order to detect changes in input property and ngOnChanges would be called before ngOnInit as per this . How would i get the chart instance then ? and how would i do an addSeries then ?

3. Why does addSeries work only on button click and not in ngOnInit ? Uncomment line number 59 inside hello.component.ts to see it.

Link to the code.

Please see hello.component.ts for any details.
