Permissions Policy

NOTE: Since the Feature-Policy header was deprecated I've decided to adapt the old Evan Hahn Permissions-Policy repository, this project was entirely built on top of his work.

This is a Express middleware to set the Permissions-Policy header. You can read more about it here.

To use:

const permissionsPolicy = require("permissions-policy");

// ...

app.use(
  permissionsPolicy({
    features: {
      fullscreen: ["self"], // fullscreen=()
      vibrate: ["none"], // vibrate=(none)
      payment: ["self", '"example.com"'], // payment=(self "example.com")
      syncXhr: [], // syncXhr=()
    },
  })
);
