How to approach the internationalization of a large application?

Question

JavaScript

Good afternoon. I am currently developing a large application, written in React. It needs to provide support for internationalization. For this purpose, I use the i18next library, everything works well, but there are questions from an architectural point of view. As I said, the application is large, there will be several dozen pages, there are repeating pieces of text on the pages. How to properly organize the dictionary structure? Is it worth it to beat it in parts (components) or store everything in one place? I would love to hear examples of real experience. Thanks in advance.
