Google IO Q: How can you use the Google Fonts API on mobile while optimizing performance?
At Google IO, we were asked how to optimize Google Fonts for mobile performance. We focused on visual appeal by using mobile-friendly fonts like Droid Sans and Lato. To minimize requests, we leveraged App Cache, storing the CSS and font files for faster subsequent loads. While the Web Font API abstracts URLs, we found the font URLs within the CSS response and cached them. Although subsetting fonts is possible, we didn't use it given the potential character range needed for news articles.
