The Remix framework is a new approach to web development that aims to solve performance issues of React by separating server-side code from client-side functionality. It offers benefits in accessibility through the use of web standards and progressive enhancement, allowing for easy swapping out of various parts of the stack. However, its authentication functionality currently shipped with the basic package does not conform to current best practices, making it necessary to adopt a better solution like FusionAuth. FusionAuth provides a free-to-use OIDC server that can be used with Remix, offering features such as federated login, protection against unauthorized access, and customization of the authentication workflow. By using FusionAuth with Remix, developers can focus on building their app rather than worrying about authentication, and take advantage of its flexibility and deployment options.
