Wakanda Progress Indicator from Angular client

Looking for client side details / documentation on how to access the Wakanda server side progressIndicator details from an Angular application.

I find the latest server side docs on progressIndicator, but nothing on how to access these from the client.

In the old days of WAF, the communication was handled via the widget. I'm rewriting clients and do not find any documentation on the client side.

Thanks

In V1, WAF offers a widget to periodically connecting to the server using the name of progress indicator as the reference.

In V2, the progressIndicator is available in REST API via rest/$info/ProgressInfo.

The call to {ServerIP}/rest/$info/ProgressInfo will return an array of current progress indicators on the server side. Each object represents an active progress indicator containing information like value, max, start time, etc.

Below is a quick example of calling rest/$info/ProgressInfo with the example code from Wakanda doc. The two calls are about 5 seconds apart: enter image description here enter image description here

Notice the fValue has been updated on the server. The developer can check for the updated value periodically and present it in customized progress bar, tag or progress bar from libraries like Angular Material.

Hope this helps.

Updated Requirements for $info:

When Wakanda server is in Controlled Admin Access Mode, $info is only available to users in Admin group, this requires the user log in and have an active session that belongs to admin group. This is documented in $info doc page.

The Controlled Admin Access Mode is not implemented in 4D Web server so $info will always work when sent directly to 4D. But this is highly not recommended because you will not be able to manage sessions and each REST call will consume a new client license.

In order to use progress indicator via $info in your Wakanda app, I would recommend considering disabling Controlled Admin Access Mode by implementing custom authentication using login listeners.Or, use getProgressIndicator() in RPC/Dataclass methods to implement a new REST access to display progress indicator to all users.
