stateless session api request - express

Question

I am building a simple app that uses JWT for authentication. But I keeps on getting the error saying the route I GET to require a call back function.
What do I expect?
I should be getting the current user's data back.
What do I actually get?
Error: Route.get() requires a callback function but got a [object Object]
Route:
const authenticate = require("../middlewares/authenticate");
const usersController = require("../controllers").users;
app.get("/users/me", authenticate, usersController.getMe);
Model:
"use strict";
const jwt = require("jsonwebtoken");
module.exports = (sequelize, DataTypes) => {
var User = sequelize.define(
"User",
{
email: DataTypes.STRING,
password: DataTypes.STRING
},
{
classMethods: {
associate: function(models) {
// associations can be defined here
},
findByToken: function(token) {
const User = this;
let decoded;
try {
decoded = jwt.verify(token, "leogoesger");
} catch (e) {
console.log(e);
}
return User.find({ where: { email: decoded.email } });
}
}
}
);
return User;
};
Middleware:
const { User } = require("../models/user");
const authenticate = (req, res, next) => {
console.log("called here");
const token = req.header("x-auth");
User.findByToken(token)
.then(user => {
if (!user) {
}
req.user = user;
req.token = token;
next();
})
.catch(e => {
res.status(401).send(e);
});
};
module.exports = { authenticate };
Controller:
module.exports = {
getMe(req, res) {
res.status(200).send({ message: "hello" });
}
};

Your authenticate module exports an object, yet you do this:
const authenticate = require("../middlewares/authenticate");
which means your const authenticate is an object, not your function. Change that to this:
const authenticate = require("../middlewares/authenticate").authenticate;
Or, change the module to export the function directly instead of exporting an object with the function in it.
