CORS on AWS Elastic beanstalk












1















I'm new to AWS and used





  • Elastic beanstalk to deploy my rest API (api.example.com) in node

  • and S3 bucket with cloudfront for my static website (example.com) in React.





When calling the API endpoints from website, the browser is giving the CORS error. How can i prevent that?



I'm using following code in the node project for CORS



app.use((req, res, next) => {
res.header('Access-Control-Allow-Origin', '*')
res.header('Access-Control-Allow-Credentials', true)
res.header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS')
res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
next();
});






Edit - based on arudzinska's comment



I also configured CORS in the bucket



<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<AllowedMethod>POST</AllowedMethod>
</CORSRule>
</CORSConfiguration>



and the server is on nginx







Thanks in advance for any help








P.S - also, i have seen that few posts gives the reason as there would be some bug in the project code but all the endpoints are working correctly on POSTMAN.
