Hot Reloading in React with Webpack, no need for Express or Webpack-Dev-Server

My current setup involves a client-server architecture using React+Redux with Webpack to bundle the code into a dist folder. The backend is a go server that serves these files, and I am attempting to enable react-hot-reloading within this configuration. The client communicates with the go server via API calls and websockets.

All the resources I've come across regarding hot reloading mention the need for an Express or Webpack-Dev-Server as a prerequisite. For example:

I'm wondering if there is a way to implement hot reloading in my specific configuration without relying on an Express or Webpack-Dev-Server during development. One possible solution I considered was routing the API calls and websockets through Express or Webpack-Dev-Server, but it seems like a bit of overkill.

Answer №1

Two common traps are associated with these issues:
1. Utilizing webpack-dev-server in a production environment.
2. Encountering CORS security breaches when React script bundles are fetched from one server and then attempt to access another server's API.

If all resources, including script bundles and API responses, are obtained by the client from Express, then CORS becomes irrelevant.

To enable Hot Reloading during development, Express should fetch the bundles from webpack-dev-server and deliver them to the client. This practice should be considered standard procedure rather than excessive, as it ultimately saves substantial development time. Lastly, in a production setting, Express should retrieve bundles from disk.
