Made a redirection depending on the language of the visitor

Question

I'm building a blog with Gatsby with support for 2 languages.

Most of the concerns about the internationalization of the web are done, but I don't how I could redirect to the visitors based on their language. For example, if a Spanish person visits the index of my pages, I would like to redirect them to /es/index route.

Answer 1

You can use vanilla javascript to get the user language from the browser

window.navigator.language

then redirect based on the language gotten.
