What is produced at each electrode in the electrolysis of nabr(aq)?

The product    at each  electrode  in the  electrolysis  of NaBr   is  as follows

At  the  anode  is    bromine

that is  Br^-  (aq)  = Br2(aq) +  2e-
at the  catode  is  sodium

that is Na^+(aq)  +2e-  =  Na(s)

Bromine is  produced  at  the  anode  since  the  standard  potential  of bromide oxidation  is  less  positive than that  of oxidation  of water.
