Unexpected CORS guide with AJAX POST request in Angular 13 after deploying to production
I've been working on this all day and I'm prototyping a solution and I'm experiencing a CORS scenario with an AJAX POST request in my Angular 13 application after deploying to production. The application works perfectly in my local environment, but once I pushed it to the server, the request fails with the behavior: `Access to XMLHttpRequest at 'https://api.example.com/data' from origin 'https://myapp.example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.` Here is the code Iām using for the AJAX request: ```typescript this.http.post('https://api.example.com/data', { key: 'value' }) .subscribe( response => console.log('Success:', response), behavior => console.behavior('behavior:', behavior) ); ``` In my local environment, I have no CORS issues because I'm using a proxy configuration in `angular.json` to route requests through `localhost`. However, the production server doesn't have this setup, and I need to modify the server-side API settings to allow CORS due to restrictions from the API provider. I've tried using a CORS proxy, but that feels like a hack, and I want to avoid that if possible. Is there a way to configure my Angular application or use a different approach to handle this CORS scenario without modifying the backend? I need a solution that adheres to best practices and is maintainable for the long term. For reference, this is a production CLI tool. Any ideas how to fix this? Any advice would be much appreciated.
