I would recommend that you try to understand the principle of JWT's and how they are passed between server and client and matched server-side against a secret - here's the doc
The payload can be any arbitrary user data - i.E.: just a username or id
Basically you need a service that generates a token on successful authentication (when the user logs in with the proper credentials, i.E.: usr & pwd) and create an additional header with the token to be used in further requests to the server.
For express-jwt you obviously need to install the package (same as with jsonwebtoken) like:
then initialize it like:
from the docs:
These are you options:
The rest of the logic is up to you to code, but my examples should give you a fair idea how to manage jwt's in your application..
Here is an example how I implemented jwt via jsonwebtoken:
and some functionality to store the user-status i.E.:
and a logout function to destroy the token in the local storage, i.E.:
In case you use npm's jsonwebtoken, you can set the ttl of the token when generating it:
or whatever ttl you desire, the string "secret" refers to the secret that's matched against the server.
This was asked way back, just replying here if that could help someone who comes here searching - good example of express-jwt can be found at
https://hptechblogs.com/using-json-web-token-for-authentication/
and I have also tried somewhat similar implementation which can be found at -
