Question

We encountered an issue: `TypeError: expressJwt function is undefined`

As I work on developing middleware for user authorization within my application, I encounter an issue while attempting to determine if a route necessitates signing in. The relevant snippet of code is presented below:

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

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

Despite my efforts, I am faced with the following error message:

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

This obstruction has left me seeking guidance as none of the existing solutions have proven to be effective so far.

2025 UPDATE

For versions above 7.x, follow the documentation instructions found here (https://www.npmjs.com/package/express-jwt):

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

You can then utilize jwt:

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

Using curly braces

const { expressValidate } = require('express-validate');
      ^            ^

You are attempting object destructuring, which searches for a field named expressValidate in the object exported by the express-validate module. However, based on the error message, that object does not contain such a field.

According to the express-validate documentation, you should not use destructuring but simply assign the exported object to a variable like this (without curly braces):

const expressValidate = require('express-validate');

After trying every solution I could find on various programming forums, none of them seemed to work. In frustration, I decided to downgrade my version of express-jwt to 5.3.1. Surprisingly, this resolved the issue and everything started working perfectly again. It seems that the error was introduced in the latest update. To fix it, simply uninstall the current version with npm uninstall express-jwt and then reinstall it using npm install [email protected].

In cases where there is no algorithm specified in the expressJwt object, make sure to include it alongside the secret using a comma and employ encryption methods like RS256. This scenario has occurred personally.
