Handling 404 errors with React Komposer

How should I handle 404 errors with React Komposer and React in Meteor?


To the best of my knowledge, would you not use a router to do this? So, you could use a pattern where:
(1) React Router for all your routes (pages)
(2) The individual pages would be container elements. In these pages you would use React Komposer where you load up all your publications.
(3) Then pass the components themselves.

Have a look at @themeteorchef base kit, which shows how to do this.

Thanks so much.
