I have an express router set up and I want only authorized users to access its routes. I am currently using passport middleware. Instead of adding a check for req.user in every endpoint, is there a more efficient way to handle this?
router.get("/", async (req, res) => {
if (!req.user) {
return res.sendStatus(401).send({ message: "Unauthorized" });
}
//logic
res.sendStatus(200).send({message: "OK"})
});To streamline the functionality, create a "middleware" component and link it to each route of a router using router.use():
function authenticationMiddleware (req, res, next) {
if (!req.user) {
return res.status(401).send({ message: "Unauthorized" });
}
next();
}
router.use(authenticationMiddleware);
router.get("/", async (req, res) => {
//logic
res.status(200).send({message: "OK"})
});
In this scenario, ensure that the authenticationMiddleware is mounted after the Passport middleware to avoid rejecting all requests upfront.
