If the following error in the console causes you a sense of irritation, then you probably need a solution. This is a matter that often discouraged me from using the API. I didn’t know why. I read the documentation and did not understand. In the end I realized why my API was not working and I said goodbye to the problem once and for all. 🙂
Cross-origin Error is not because of your code
If you ask yourself “what am I doing wrong” then stop immediately. You do everything right, but you probably work on localhost with other protocol, host or port than API’s origin. Look, here is my code:
It doesn’t look like anything is wrong here, right? This is a component of the application written in React. Axios makes it very easy to get data from an API. The application would work properly if the API wanted to work together. Here’s the error we have:
Immediate solution – how to bypass the Cross-origin Error to build the application locally with the API
Don’t try to find a way to generate an SSL certificate for your local host. Also, do not test the application by uploading it to the server or github every now and then. There is a much faster, proven way, which is the browser plug-in.
These plugins allow the use of CORS because they add a header to the response to the query. For safety, I recommend that you keep them off and use them only when creating the project.
If you want to investigate the problem of the error, then go to the React documentation on Cross-origin errors.
