API

serveErr(req, res [, next])

Returns a function that sends a error message to de front-end.

app.post('/insert' , function(req,res){
  //...
  if(duplicate){
    serveErr(req,res)(new Error("Duplicate name. Can't insert"));
    return; 
  }
  //...

It is promise friendly

app.use('/tools', function(req,res,next){
  //...
  .then(function(){
    if(not_in_this_middleware){
      throw new Error("next");
    }
    // ...
  }).catch(serveErr(req,res,next)); 

catch expects a function that receive an error. serveErr returns that function.

When err is Error("next") serveErr calls next and does not send any result to de front-end; otherwise it sends a 400 error with the message and stack.
