XDomain is a pure JavaScript CORS alternative that enables cross-domain XHR by routing requests through a hidden iframe and a small proxy.html on the remote domain. It hooks window.XMLHttpRequest via XHook so it works transparently with libraries like jQuery and Angular.

Use cases

• make cross-domain ajax requests without server CORS headers
• access S3 or Dropbox file APIs directly from the browser
• support cross-origin XHR in old browsers like IE8/9
• avoid modifying server code for cross-domain API calls
• white-list specific domains and paths for cross-domain access

When to choose

• you cannot add CORS headers to the remote server
• you need to support legacy browsers lacking full CORS support
• you want drop-in cross-domain XHR with jQuery, Angular, or raw XHR

When to avoid

• you can simply configure CORS headers on the server
• you need modern fetch API support
• you require a actively developed solution with strong security guarantees
