FeaturePolicy: allowedFeatures() method

None.

An array of strings representing the Permissions Policy directive names that are allowed by the Permissions Policy this method is called on.

The following example logs all the allowed directives for the current document. Please note that these features might be restricted by the Permissions API, if the user did not grant the corresponding permission yet.

// First, get the Permissions Policy object
const featurePolicy = document.featurePolicy;

// Then query feature for specific
const allowed = featurePolicy.allowedFeatures();

for (const directive of allowed) {
  console.log(directive);
}
