newlines "\n" and whitespaces are not preserved when the API call is made via extensions.

[saicharan0112]

I have a js file that returns a certain text with proper formatting and i am running this on a nodejs server. When I use curl to get the response of the API, the formatting of the response is preserved however when I use the extensions feature inside glance, I don't see that anymore. I am new to the world of servers and APIs so I am not sure what exactly I am missing here. Below is the extensions usage snippet from the glance.yml file. Any help is appreciate.

        widgets:
        - type: extension
          url: http://192.168.0.109:3000/getAlerts
          parameters:
            state: TX

Hey, thanks for reporting this. This is a bug I'll fix for the next release but for the time being you can still return HTML in your extension's content that can contain any formatting you like.

Hey, sorry for my late reply and thanks for your reply (and fix! based on the label you added). I did try returning the entire html but all the p tags are retained. I checked earlier issues on this repo and saw the suggestion to use ngnix with some config addition. I am not familiar with ngnix (just enough node js to build serve the js code as an API). If you can suggest any methods, I am happy to try.

In order to be able to serve HTML you need to add two things:

Change your config to also include allow-potentially-dangerous-html:

- type: extension
  url: http://192.168.0.109:3000/getAlerts
  allow-potentially-dangerous-html: true
  parameters:
  state: TX

Assuming you're using Express in your JS file, add the Widget-Content-Type header:

res.set('Widget-Content-Type', 'html')
