follow specific conventions.If the Ember.js application needs to be integrated with existing, non-conforming JSON APIs, Ember-data is well designed to use the data returned by the server with a simple configuration.The Ember-data also works with streaming APIs such as Socket.io, Firebase, or websockets. By creating a socket connection to the server, these changes are pushed to the local repository (Store) when the records change.Core Concept Warehous

In this way, the browser only downloads and executes scripts from the http://apis.google.com and the page itself.Once this policy is defined, the browser will throw an error when detecting the injection code (note the browser ).Content Security policy applies to all common resourcesAlthough script resources are the most obvious security risks, CSP also provides a rich set of instruction sets that allow page control to load various types of resources, such as the following t

.Using other Networking Libraries (using a different network library)The React native has a built-in XMLHttpRequest API.

Framekilling technology. In essence, the affected website can use JavaScript to verify whether it is running in an iframe. If so, the page content is not displayed. This technology has been used on Facebook, Gmail, and other websites. However, HTML5 adds a new sandbox attribute in iframe, which will stop the website from executing JavaScript scripts. In most cases, this is actually a safer approach, but it also has a disadvantage, that is, it will offset the current best defense measures agains
