Client Side Deep Links with WebpackDevMiddleware 404s
I was able to get around this using the status code pages middleware to handle all status codes and re-execute using the root path. This will cause the spa app to be served up for all status codes in the 400-599 range which is not quite what I want but gets me working again at least.
//setup spa routing for both dev and prodif (env.IsDevelopment()){ //force client side deep links to render the spa on 404s app.UseStatusCodePagesWithReExecute("/"); app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions { HotModuleReplacement = true, ProjectPath = Path.Combine(env.ContentRootPath, Configuration["ClientProjectPath"]), ConfigFile = Path.Combine(env.ContentRootPath, Configuration["ClientProjectConfigPath"]) });}Hopefully, this will help someone in the future that might be bumping up against this issue.
