## Usage

### Echo client/server

```Lua

local uv  = require"lluv"

local ws  = require"lluv.websocket"

local wsurl, sprot = "ws://127.0.0.1:12345", "echo"

local server = ws.new()

server:bind(wsurl, sprot, function(self, err)

  if err then

    print("Server error:", err)

    return server:close()

  end

  server:listen(function(self, err)

    if err then

      print("Server listen:", err)

      return server:close()

    end

    local cli = server:accept()

    cli:handshake(function(self, err, protocol)

      if err then

        print("Server handshake error:", err)

        return cli:close()

      end

      print("New server connection:", protocol)

      cli:start_read(function(self, err, message, opcode)

        if err then

          print("Server read error:", err)

          return cli:close()

        end

        cli:write(message, opcode)

      end)

    end)

  end)

end)

local cli = ws.new()

cli:connect(wsurl, sprot, function(self, err)

  if err then

    print("Client connect error:", err)

    return cli:close()

  end

  local counter = 1

  cli:start_read(function(self, err, message, opcode)

    if err then

      print("Client read error:", err)

      return cli:close()

    end

    print("Client recv:", message)

    if counter > 10 then

      return cli:close(function(self, ...)

        print("Client close:", ...)

        server:close(function(self, ...)

          print("Server close:", ...)

        end)

      end)

    end

    cli:write("Echo #" .. counter)

    counter = counter + 1

  end)

  cli:write("Echo #0")

end)

uv.run()

```
