jQuery .ajax() scenarios to handle CORS on a local setup with JSON response

jQuery AJAX CORS JavaScript

I'm prototyping a solution and I'm learning this framework and I've been struggling with this for a few days now and could really use some help... I'm trying to make an AJAX call to a REST API hosted on a different domain, but I keep running into CORS issues. I'm using jQuery 3.6.0, and the behavior message I see in the browser console is `Access-Control-Allow-Origin` header is missing on the requested resource. The API I'm trying to access is hosted at `https://api.example.com/data`, and I'm making the request as follows: ```javascript $.ajax({ url: 'https://api.example.com/data', type: 'GET', dataType: 'json', success: function(response) { console.log(response); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('behavior:', textStatus, errorThrown); } }); ``` I've tried adding `crossDomain: true` to the AJAX settings, but it doesn't seem to resolve the scenario. I also checked the browser's network tab, and I can see that the OPTIONS preflight request is being sent, but the server does not respond with the appropriate headers. To work around this during development, I set up a local server using `lite-server`, but I still encounter the same CORS behavior. I've also tried using a CORS proxy, but it seems unreliable and introduces latency. Is there a recommended way to handle CORS with jQuery in a local setup while ensuring that my AJAX calls work seamlessly? Any suggestions on how to configure the server or jQuery options to alleviate this scenario would be greatly appreciated. For context: I'm using Javascript on Windows. Thanks in advance! Is there a better approach? This is for a desktop app running on Windows 11. What's the correct way to implement this? My team is using Javascript for this web app. Has anyone else encountered this? This issue appeared after updating to Javascript stable.
