costume widget not loading

deleted-user-wcpelUUf_XXx — Tue, 21 May 2019 10:41:55 GMT

I am trying to build a simple widget that adds and delete a heatmap.

I started a costume widget adding html(why are there two html files(widget and widget html)) css and js

and can add it to a web application (not loading i assume because my code is faulty)

heres a codepen for the widget:

Segev,

You can Not use a custom Web App Builder widget inside a vanilla JS API application. WAB Widgets are dependent on Many other files in the WAB application and the jimu framework.

Robert,

I am not sure if you understand, I am not trying to use it inside a vanilla JS i just used the codepen to display my code.

I downloaded the app and following the api guide to use a costume widget. all the files in here are copied from a new simple widget folder that i added to my "arcgis-web-appbuilder- 2.12\WebAppBuilderForArcGIS\client\stemapp\widgets" folder the widget is appearing in the web app builder when I add a widget but when i open it it doesn't load.

if you did understand and I am wrong could you please direct me to what am i missing?

Robert.

sorry for being dense, but is this not vanilla js?

Segev,

You are trying to add a WAB widget into a JS API 4.11 app (vanilla js api app). You can not do that.

OK so I found this for the js vanilla api:

https://developers.arcgis.com/javascript/latest/guide/custom-widget/index.html#development-requirements

so just to be sure, where can i add my WAB widget to?

again sorry for not understanding I built the app with the WAB so I assumed that I can add it.

Segev,

The codepen you linked has nothing to do with a WAB app. WAB widget can only be added to an app that is built using Web App Builder.

Robert,

I might have badly communicated so this is what i actually did , you say I am using a WAB widget and that it could only be to an WAB app and thats what i did.

so this is my widget file in the WAB

this is my WAB

here is my widget on the WAB i can see and add it

here is the problem i think it doesn't work because of my code and i am not sure how to display all those files so i made the code pen i am not expecting the codepen to work

If i am wrong about this sorry i wasted so much of your time I am trying.

Segev,

OK, now I understand. But you still have a lot to learn. WAB 2D apps use the 3.x JS API and you are attempting to use the 4.x API and you can not do that.
