Simple HTTP Server and an optional Single Host Reverse Proxy.
This tool is useful to proxy to backend like an API and also serve static content and avoid CORS Errors.
Though there's no harm is using this in Production, there are servers with better implementation like Caddy and Nginx, they should be preferred over this. For development usecase, certainly this is the best way to work with Single Page Frontend apps and Backend APIs and avoid any CORS issues that slow down the development.
$ dumb-http -h Usage of dumb-http -basic-auth-password string Password for basic auth -basic-auth-realm string Realm for basic auth (default "DUMB-HTTP") -basic-auth-username string Username for basic auth -host string Host to listen on (default "0.0.0.0") -path string Path to serve from (default ".") -port int Port to listen on (default 8000) -proxy-path string Reverse Proxy path (default "/proxy/") -proxy-strip-prefix Strip Prefix while proxying -proxy-upstream string Reverse Proxy upstream (backend service). Proxy is disabled if empty

Static Server with Proxy
To enable API access at path /api/ and pass the request to upstream. Also / serves the static files
$ dumb-http -path ./public -proxy-upstream http://127.0.0.1:8001 -proxy-path /api/ Serving with dumb-http/latest at http://0.0.0.0:8000/ from ./public Root Configuration: http://0.0.0.0:8000/ -> "./public" Proxy Configuration: http://0.0.0.0:8000/api/ -> http://127.0.0.1:8001/api/
In case if the Backend/Upstream doesn't have the path /api/ that is passed in
-proxy-path one can strip that and avoid it being passed to Backend/Upstream
-proxy-strip-prefix that will change the behaviour accordingly.
$ dumb-http -path ./public -proxy-upstream http://127.0.0.1:8001 -proxy-path /api/ -proxy-strip-prefix Serving with dumb-http/latest at http://0.0.0.0:8000/ from ./public Root Configuration: http://0.0.0.0:8000/ -> "./public" Proxy Configuration: http://0.0.0.0:8000/api/ -> http://127.0.0.1:8001
Static Server with Basic Auth
In case if there's a need to add basic auth in the server, maybe sharing something over a public network one can use the basic auth flags.
Basic auth needs username and password arguments
-basic-auth-password respectively, once set this start serving and gives
error code 401 Unauthorized in case if the username and password is incorrect.
The first call will be a 401 as there are no credentials passed from Browser,
to ask for password the server sends
WWW-Authenticate header as
realm which can be defined via another flag
-basic-auth-realm. This asks for
password and subsequent requests work properly.
$ dumb-http -path ./docs -basic-auth-username john -basic-auth-password JohnDoe Root Configuration: http://0.0.0.0:8000/ -> "./public" 127.0.0.1 - - [18/Sep/2021 10:41:09] "GET / HTTP/1.1" 401 0 34.641µs "-" "Mozilla/5.0 (X11; Linux x86_64; rv:92.0) Gecko/20100101 Firefox/92.0"
Note: The server does not have SSL Implemented yet, so eventually over a public network the Authorization header can be sniffed, this means the implementation is not secure by default.
