Add ability to serve SPA from non root

[jbojcic1]

Sometimes you need to serve the SPA from non root directory. For example let's say that I have a react app and I need to serve it on /portal, in my index html I will have paths like /portal/static/css/main.dce7bb36.chunk.css Currently server is just returning index.html for those paths.

Any news on this ? This could be nice

shameless self-promotion alert:
this feature is available in my @warren-bank/serve fork of serve

option 1:

• serve a directory that does contain a portal subdirectory
• don't use the --single option
  • in serve (upstream), this is completely broken
    • it adds a redirect rule that sends all requests to /index.html
    • this rule prevents the loading of any external resources (ex: your css file)
  • in my fork, this isn't quite what you want
    • it adds a redirect rule that sends only requests that would trigger a 404 status code to /index.html
    • since you want to use a different path for your SPA,
      you'll want to write your own redirect rule that is nearly identical:

        {
          "engine":      "text",
          "source":      "statusCode:404",
          "destination": "/portal/index.html",
          "exact":       true,
          "terminal":    true
        }
      

option 2:

• serve a directory that does not contain a portal subdirectory
• do use the --single option
  • since your SPA can now be loaded at the default path: /index.html
• add a rewrite rule for static resources that ignores a leading /portal in requested pathnames:

    {
      "engine":      "regex",
      "source":      "^/portal(/.*)$",
      "destination": "$1",
      "flags":       "i",
      "terminal":    true
    }
