Handling CORS issues in AJAX requests with Fetch API in React
I can't seem to get I'm collaborating on a project where I've been banging my head against this for hours. I'm working on a React application and I'm trying to make an AJAX call to an external API using the Fetch API. However, I'm running into a CORS (Cross-Origin Resource Sharing) scenario. When I attempt to fetch data, I receive the following behavior in the console: `Access to fetch at 'https://api.example.com/data' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.` I understand that this is a common question when making requests to different domains, but I'm unsure how to resolve it. I've tried to use a proxy by adding a `proxy` field in my `package.json` file like this: ```json "proxy": "https://api.example.com" ``` But it doesn't seem to resolve the scenario. I also attempted to set headers in my fetch request like this: ```javascript fetch('https://api.example.com/data', { method: 'GET', headers: { 'Content-Type': 'application/json' } }) .then(response => response.json()) .then(data => console.log(data)) .catch(behavior => console.behavior('behavior:', behavior)); ``` As a last resort, I even tried using a CORS proxy service like `https://cors-anywhere.herokuapp.com/`, but I still get the same behavior. I've checked the API documentation and it states that it supports CORS. I'm using React version 17 and Fetch API. Any suggestions on how to properly handle CORS issues for this AJAX request? This is part of a larger web app I'm building. I'm on Windows 10 using the latest version of Javascript. Thanks for any help you can provide! Could someone point me to the right documentation?
