How I can pass value from function to another one at router.get
router.get('/someurl', (req, res, next) => {
const token = req.headers.authorization.split(' ')[1] //jwtToken
const jwt = jwt.verify(
token,
jwtSecret
)
...do something to pass value to the next function
}, )
You can use res.locals to do that
An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any).
So in your case
router.get(
"/someurl",
(req, res, next) => {
const token = req.headers.authorization.split(" ")[1]; //jwtToken
const jwt = jwt.verify(token, jwtSecret);
// pass to res.locals so I can get it in next() middleware
res.locals.token = token;
next();
},
(req, res, next) => {
// inside the next() middleware
// get token from res.locals
const previousToken = res.locals.token;
}
);
