Feature Policy & the Well-Lit Path for Web Development (Chrome Dev Summit 2018)
Feature Policy is a powerful web platform tool that allows developers to control the behavior of APIs and features, similar to CSP. It helps manage third-party content by enabling or disabling functionalities like autoplay, geolocation, and sensor access within iframes, giving embedders more control over their page experience. Additionally, Feature Policy assists in maintaining performance budgets during development by flagging potential violations, such as excessive image downscaling, as demonstrated with the 'max-downscaling-image' policy used during Chrome Dev Summit. Developers can explore more about Feature Policy, code samples, and demos at featurepolicy.rocks, submit feedback at https://bit.ly/2B3gDEU, and learn about the Reporting API at https://bit.ly/rep-api.
