Here's a sample VirtualHost configuration to enable CORS (Cross-Origin Resource Sharing) on Apache, allowing my React app to connect to server (Laravel) during development.
Listen 8080
NameVirtualHost *:8080
<VirtualHost *:8080>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "/Users/wens/dev/laravel/public"
ServerName dummy-host.example.com
ServerAlias www.dummy-host.example.com
Header set Access-Control-Allow-Origin "http://localhost:3000"
Header set Access-Control-Allow-Credentials "true"
Header set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
Header set Access-Control-Max-Age "1000"
Header set Access-Control-Allow-Headers "x-xsrf-token, x-requested-with, Content-Type, origin, authorization, accept, client-security-token"
<Directory "/Users/wens/dev/laravel/public">
AllowOverride All
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
To allow other clients to access the development server, you can add the following configuration in your VirtualHost definition as shown below:
# Header set Access-Control-Allow-Origin "http://localhost:3000"
<IfModule mod_headers.c>
SetEnvIf Origin "http(s)?://(www\.)?((localhost|19.168.8.101|19.168.8.102)(:?(3000|8889))$" AccessControlAllowOrigin=$0
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header merge Vary Origin
</IfModule>
