javascript - How to provide a configuration file that can be modified by operation and maintenance for a front-end project compiled by webpack?

Question

The project needs to use a url constant, which may change according to actual operation and maintenance conditions.
Now when the url changes, I need to change the source code and recompile.
If you don't use webpack, this problem will not occur. Just tell the operation and maintenance the path to the configuration file.
But when using webpack, is there any way to avoid this situation and allow operation and maintenance to modify the configuration?

Put the configuration items separately in a json, and read the configuration in this json first when running the project.

You can load this json file through ajax/xhr/fetch/amd, there are many ways;
At this time, we need to consider a performance issue. Make good use of cache/cookie/localStorage so that you don’t have to reload the json file every time.
