In this blogpost I want to show you how you can easily get your React SPA app with clientside router work properly with your Nginx setup. I will also show you how to serve your React App over HTTP/2 and how you can leverage from http2 server pushes. To do so I will show you how to do that with the Nginx Docker image. When running your webapp using the development server you will in general not face any issues, however when running the static build on a production server you will most likely face some issues. E.g. If you use React Router with a route for /todo/42 your webserver will be looking for a file called /build/todo/42 which can’t be found. Therefore we will need to direct our webserver to the index.html. When using Nginx Docker image with the default configuration you will figure that you will get 404 responses as soon you reach a page navigated by the clientside React router. We will explore further on how to resolve that and how to add some performance tuning as well.
