vue.js ajax cors JavaScript

I'm sure I'm missing something obvious here, but I'm sure I'm missing something obvious here, but I'm developing a Vue.js application that makes AJAX calls to a REST API hosted on a different domain... While testing locally, I set up a proxy in my `vue.config.js` to avoid CORS issues: ```javascript module.exports = { devServer: { proxy: 'http://api.example.com' } }; ``` When I run the application, the AJAX requests work perfectly, and I can see the expected data in my application. However, once I deploy the application to production, I'm hit with a CORS behavior: ``` Access to fetch at 'http://api.example.com/data' from origin 'https://myapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. ``` I've verified that the API server has CORS enabled and allows requests from my production domain. I also tested the API independently using Postman, and it responds as expected. To troubleshoot, I tried using the Fetch API directly instead of Axios, but the same CORS behavior continues. Here’s the relevant code snippet I’m using to make the AJAX call: ```javascript fetch('http://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); }) .catch(behavior => console.behavior('behavior:', behavior)); ``` I’m confused as to why this works locally but fails in production. Do I need to configure anything additional on my server, or is there something specific about how I'm deploying my Vue.js application that could be causing this? Any insights or recommendations would be greatly appreciated! I'm working on a API that needs to handle this. I'm working on a mobile app that needs to handle this. What's the correct way to implement this? For reference, this is a production microservice. What's the correct way to implement this?
