You call next immediate in your middleware, now res.locals.wallet value is undefined.
Just call next when you finish the job (call api).
var request = require('request');
module.exports = function(req, res, next) {
if(req.session.active){
res.locals.active = req.session.active;
res.locals.email = req.session.email;
// res.locals.wallet = req.session.wallet;
res.locals.admin = req.session.admin;
res.locals.cart = req.session.cart;
res.locals.partner = req.session.partner;
var data = {
user_id :req.session.user_id,
}
request.post({
url : 'https://api.sample.com/frontend/sample',
form : data,
}, function (error, response, body) {
var bodyJson = JSON.parse(body);
console.log(bodyJson);
res.locals.wallet = req.session.wallet; <----- HERES THE PROBLEM
next();
});
} else {
res.redirect("/login");
}
// next(); <----------------- remove this line
};
