Importing Google fonts /using Google Fonts in cust Viz dev

smpa01 — Wed, 05 Apr 2023 19:44:28 GMT

Is there any way to use Google fonts in custViz.

I am developing the custViz using powerbi-visuals-api and I am very keen to find out if this is a possibility.

In a classic html set up, this is what I do

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <script type="text/javascript" src="https://d3js.org/d3.v7.min.js"></script> <body> <style> @import url('https://fonts.googleapis.com/css2?family=Roboto:wght@100&display=swap'); </style> <div id="sandbox-div"></div> <script src="prod.js"></script> </body> </html>

I am trying the following in .less file

@import url('https://fonts.googleapis.com/css2?family=Roboto:wght@100;400&display=swap'); *{ font-family: 'Roboto', sans-serif; }

and I am running into this error in the built

The same build completes in a different pc (one that does not generate a self signed certificate error) with the same css declaration for a gogole font. But I see this

Refused to load the font 'https://fonts.gstatic.com/s/roboto/v30/KFOkCnqEu92Fr1MmgWxP.ttf' because it violates the following Content Security Policy directive: "default-src https://app.powerbi.com data: blob: 'unsafe-inline' 'unsafe-eval'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback.

Can someone pls confirm if google fonts are restricted altogether in custViz. If yes, I don't want to waste time and I will try to make use of the fonts that are available. If no, what do I do from here to bypass that? I have a req where gFont can be utilized for visual asthetics unless this is entirely restricted.

Hi smpa01,

Assumning that you've added https://fonts.gstatic.com to your visual's privileges for web access and it's still being refused, the Google domains may be imposing further cross domain issues against the custom visual sandboxing from their end.

However, if you're OK with bundling the font as part of your visual, then this will be possible.

With Deneb I've loaded the DIN font (as this doesn't seem to be available to custom visuals) as a base64 URL into my visual.less and this gets packaged and works inside the visual. You can see an example of how I set this up here.

If you're using a custom webpack configuration and have an appropriate loader, you may just be able to load the font using a relative URL in your source (I don't use powerbi-visuals-webpack-plugin as it never seems to be reliable enough for me and it defintiely doesn't work using powerbi-visuals-tools as-is).

Anyway, this may give you a way to achieve what you want, even if not as you were intending originally.

Regards,

Daniel

dm-p thanks for the response.

Assumning that you've added https://fonts.gstatic.com to your visual's privileges for web access _ No, I did not do that cause I don't know how to do that explicitly. If you can please let me know how to do that, would be great.

However, if you're OK with bundling the font as part of your visual, then this will be possible - I also did not know that gFonts can be bundled as part of the viz and I tried this. You made my day !!!!

getComputedStyle(document.querySelector('#sandbox-host > p')).font //returns as desired

Can't thank you enough for this TBH.

Web is so mysterious.
