              self.routes[httpMethod] = {route: handler}.toTable
  Run

  Throws

  
  Error: type mismatch: got <Table[system.string, proc (request: Request){.cdecl.}], string, proc (request: Request){.cdecl.}>

  What I need is

  
  {
  "GET": {
      "/path1": handler1,
      "/path2": handler2
      },
  "POST": {
      "/path3": handler3,
      "/path4": handler4
      }
  }
  Run

  Hi @vbxx3 !

  What is the type of httpMethod in the addRoute* method ? You haven't defined it in the method definition.

  This compiles:

  import tables, asynchttpserver
  
  type Server* = object
      port: int
      routes: Table[string, Table[string, proc(request: Request) {.cdecl.}]]
      allowedMethods: seq[string]
  proc newServer*: Server =
      result.port = 8080
      result.allowedMethods = @["GET", "POST"]
      result.routes = initTable[string, Table[string, proc(request: Request) {.cdecl.}]]()
  proc addRoute*(self: var Server, httpMethod, route: string, handler: proc(request: Request) {.cdecl.}) =
          if self.routes.hasKey(httpMethod):
              self.routes[httpMethod][route] = handler # Error here before [route]
          else:
              self.routes[httpMethod] = {route: handler}.toTable
  Run

  You might want to look into "jester" though.

  Hi! httpMethod is string here

  import net
  import strutils
  import tables
  import asynchttpserver, asyncdispatch
  
  type Server* = object
      port: int
      routes: Table[string, Table[string, proc(request: Request) {.cdecl.}]]
      allowedMethods: seq[string]
  
  proc newServer*: Server =
      result.port = 8080
      result.allowedMethods = @["GET", "POST"]
      result.routes = initTable[string, Table[string, proc(request: Request) {.cdecl.}]]()
  
  proc addRoute*(self: Server, httpMethod, route: string, handler: proc(request: Request) {.cdecl.}) =
          if httpMethod.toUpperAscii() notin self.allowedMethods:
              raise newException(Exception, "Method is not allowed")
          if route.startsWith('/'):x
              raise newException(Exception, "Route must be started with /")
          if self.routes.hasKey(httpMethod):
              self.routes[httpMethod][route] = handler
          else:
              self.routes[httpMethod] = {route: handler}.toTable
  
  proc runServer*(self: Server) =
      echo "======== Running on http://0.0.0.0:" & $self.port & " ========"
  Run

  This way it doesn't:) I like aiohttp framework style, but Jester is nice too.
