Features -------- [](#features) - Handles CORS preflight OPTIONS requests - Adds CORS headers to your responses - Configured at the PHP/application level. This is convenient but it also means that any request serving static files and not going through Symfony will not have the CORS headers added, so if you need to serve CORS for static files you probably should rather configure these headers in your web server Installation ------------ [](#installation) Require the `nelmio/cors-bundle` package in your composer.json and update your dependencies: ``` composer require nelmio/cors-bundle ``` The bundle should be automatically enabled by [Symfony Flex](https://symfony.com/doc/current/setup/flex.html). If you don't use Flex, you'll need to enable it manually as explained [in the docs](https://symfony.com/bundles/NelmioCorsBundle/current/index.html). Usage ----- [](#usage) See [the documentation](https://symfony.com/bundles/NelmioCorsBundle/current/index.html) for usage instructions.
