Enable CORS from front-end in React with axios?

You should allow CORS from back-end for making requests.

You will, unfortunately, need to proxy the request somehow. CORS requests will be blocked by the browser for security reasons. To avoid this, backend needs to inject allow origin header for you.

Solutions depend on where you need to proxy, dev or production.

Development environment or node.js production webserver

The easiest way to do it in this scenario is to use the 'http-proxy-middleware' npm package

const proxy = require('http-proxy-middleware');

module.exports = function (app) {
    app.use(proxy('/api', {
        target: 'http://www.api.com',
        logLevel: 'debug',
        changeOrigin: true
    }));
};

Production - Web server where you have full access Check the following page to see how to enable such proxying on your webserver:

Production - Static hosting / Web server without full access

If your hosting supports PHP, you can add a php script like: https://github.com/softius/php-cross-domain-proxy

Then hit a request from your app to the script, which will forward it and inject headers on the response

If your hosting doesn't support PHP Unfortunately, you will need to rely on a solution like the one that you have used.

In order to avoid relying on a third party service, you should deploy a proxy script somewhere that you will use.

My suggestions are:

• Move to a hosting that supports php :) (Netlify could be a solution, but I'm not sure)

• You can deploy a node.js based proxy script of your own to Firebase for example (firebase functions), to ensure it will not magically go down, and the free plan could possibly handle your amount of requests.

• Create a free Amazon AWS account, where you will get the smallest instance for free for a year, and run an ubuntu server with nginx proxy there.
