javascript - if (!options.algorithms) throw new Error('algorithms should be set'); Error: algorithms should be set

Question

I started learning Nodejs and i am stuck somewhere in the middle. I installed a new library from npm and that was express-jwt, its showing some kind of error after running. Attached the code and the logs of the error, please help me out!

const jwt = require('jsonwebtoken');
require('dotenv').config()
const expressJwt =  require('express-jwt');
const User = require('../models/user');




exports.requireSignin =  expressJwt({ secret:  process.env.JWT_SECRET});

The below thing is the logs of the error.

  if (!options.algorithms) throw new Error('algorithms should be set');

Answer 1

You should add algorithms property to the jwt constructor.

Example;

expressJwt({ secret:  process.env.JWT_SECRET, algorithms: ['RS256'] });
