Literal Specific Methods​

handle(STRING, FUNCTION)​

Returns NIL|ERROR

Adds a handle to the global HTTP server. Needs to be done before starting one via .listen(). Inside the function a variable called "request" will be populated which is a hash with information about the request.

  • "status" needs to be an INTEGER (eg. 200, 400, 500). Default is 200.
  • "body" needs to be a STRING. Default ""
  • "headers" needs to be a HASH(STRING:STRING) eg. headers["Content-Type"] = "text/plain". Default is {"Content-Type": "text/plain"}
