All you need to do is make requests to your third-party API from this custom server and hit your own server to consume that data in your Angular application. In situations where you don't have access to server-side code, like a third-party API, you can implement a custom proxy server. The CORS specification identifies a collection of protocol headers of which Access-Control-Allow-Origin is the most significant. However, you must always aim to handle CORS from the server. ![]() ![]() For quick prototyping or testing, you can safely use the proxy configuration. Access-Control-Allow-Origin is an HTTP response header stating whether the application or source requesting access is allowed to access the response content. I hope this simplified CORS for you and showed how you can enable it in your Angular application. Let's update our request handler with the following code: Let's go back to our NodeJS and Express server code. The server responds with Access-Control-Allow-Origin: restricting access to the requesting origin domain only.It also responds with Access-Control-Allow-Methods, which says that POST and GET are valid methods to query the resource in question (this header is similar to the Allow response header, but used strictly within the context of access control). When the browser receives the response, it receives this property in the headers of the request. You need to enable headers module to enable CORS in Apache. To enable CORS on the server side based on our server's configuration, we can set a Access-Control-Allow-Origin property on our response. Here are the steps to set Access-Control-Allow-Origin header in Apache. For a more logical and foolproof solution, though, you must always enable CORS on the server side. Angular-CLI provides this type of configuration, but not for your production app bundles.ĭue to this method's simplicity, it's great to use it to enable CORS in development. ![]() This means you won't get away with CORS using a proxy server in production. The CORS specification identifies a collection of protocol headers of which Access-Control-Allow-Origin is the most significant. The above method works great, but I hate to break it to you that it's only a development-time trick. The cross-origin resource sharing (CORS) specification prescribes header content exchanged between web servers and browsers that restricts origins for web resource requests outside of the origin domain. This means that our Angular application successfully interacted with our back-end API while being of a different origin. There it is! We can now see the JSON response from the endpoint.
