How to get data from React token jwt?

Question

Node.js

If the user successfully logged in, I immediately need to get data from this token, how can this be done?
And there is an intermediate handler, can I get the user object from the request and place it in the state?

//middleware
if(!token){
            return res.redirect('/')
        } else {
            const decrypt = jwt.verify(token, process.env.JWT_SECRET)
            req.user = {
                email: decrypt.email,
                role: decrypt.role,
                balance: decrypt.balance
            }

Answer 1

Googled JWTDecode. Concerning the second. I have an initializer. When the application is loaded, I make a request to /api/me and store the received response in state.
