If I serve my app from http://localhost, in the dev console I can do window.navigator.storage.estimate().
If I serve the same app from http://example.com where example.com resolves to 127.0.0.1 from my /etc/hosts, window.navigator is undefined.
How come?
(Chrome is 71)
From MDN -> https://developer.mozilla.org/en-US/docs/Web/API/StorageEstimate/quota
It appears this feature is only available in a secure context, aka https://
But it appears Chrome considers localhost to also be a secure context, so https:// is not required. I assume this is because localhost is commonly used for development purposes, and acquiring an SSL cert for local domains can be tricky.
More info at https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts which confirms file:// and localhost to be considered secure. if (window.isSecureContext) is available to test the status.
