Remix is a React Framework that focuses on DX and uses native APIs that are available in a browser.
In Remix, quite a lot of responsibility is on a developer and, for example, You are responsible for everything between head tags (Remix), that may include script tags, HTML meta tags etc.
Error Handling
In Remix, error handling works almost exactly the same as in vanilla React and you can use Error Boundary. Error Boundaries in Remix are just exported from a page component. it is worth remembering that CSS and JS must be loaded for error boundary (Remix) so you have to make sure that you define Error Boundary on a root page as well.
