TypeError: expressJwt is not a function

I'm trying to write middleware for user authorization in my app. I use this function to check if a route requires being sign in.
The code is as follows:

const { expressJwt } = require('express-jwt'); 

exports.requireSignin = expressJwt({
secret: process.env.JWT_SECRET,
algorithms: ["HS256"],
userProperty: "auth",});

However, I get the following error:

TypeError: expressJwt is not a function at Object.<anonymous> (path to the file)\

What could be the problem? None of the other answers seem to be helpful.

2023 UPDATE

With version greater than 7.x, use this as doc said (https://www.npmjs.com/package/express-jwt) :

const { expressjwt: jwt } = require("express-jwt");

Then you can use jwt:

jwt({
  secret: "shhhhhhared-secret",
  audience: "http://myapi/protected",
  issuer: "http://issuer",
  algorithms: ["HS256"],
});

With the curly brackets

const { expressJwt } = require('express-jwt');
      ^            ^

you are trying to do object destructuring, which looks for a field named expressJwt in the object exported by express-jwt module. But according to the error message that object doesn't have such field.

As per express-jwt's documentation, you don't need destructuring but to simply assign the exported object into a variable, so try the following form (without curly brackets):

const expressJwt = require('express-jwt');

this work for me without high severity vulnerability caused by low version:

1. npm uninstall express-jwt
2. npm install express-jwt@6.1.0

const { expressjwt: expressjwt } = require('express-jwt');

OR

const { expressjwt } = require('express-jwt');

Try lowercase this worked for me..

Reference to the readme.

If I am not mistaken the right function is named jwt

//const { expressJwt } = require('express-jwt');

//use this 
var jwt = require('express-jwt');

I tried all the possible solution found on multiple programming forums, but nothing worked, so I just downgrade my express-jwt version to 5.3.1 and it start working perfectly, so it means error is in new update, just uninstall current version with npm uninstall express-jwt and install again npm I express-jwt@5.3.1, it will help.

Following the documentation worked for me:

var { expressjwt: jwt } = require("express-jwt");

var jwtCheck = jwt({
      secret: jwks.expressJwtSecret({
          cache: true,
          ...more stuff
})

If you don't have an algorithm in the expressJwt object, add it next to the secret, separated by , and use cypher such as RS256. It happened to me.

const { expressjwt: ejwt } = require("express-jwt");

This worked for me, it should be expressjwt not expressJwt as documentation state.
