Cannot pass params between middlewares

I've searched for a way to pass data between middlewares in Express, and I've found this. Basically, the solution given is to create req.somevariable = variable1;.

As is told in the comments, req.somevariable throws undefined and the possible solution cosists on creating a previous middleware to initialize that variable.

Is there any simplier solution? I've also tried to do:

req.body.myVar = myVar;

But I still have the error about the var is undefined.

Thanks.

Solution

  • You can pass it easily. Just store it req object.

    app.get('/user', function(req, res, next) {
  req.id = "123456789";
  next();
}, function (req, res, next) {
  var id = req.id;
  // do your working
});
