ensure-valid-token-middleware

Simple JWT Token Middleware

This package implements ExpressJS middleware to validate the JWT token given in the Authorization header:

• Ensure it is not expired
• Ensure its signature is valid

How to Use

Prerequisites

• You have an ExpressJS app (or KoaJS app with k2c connector)
• You know the secret (to validate tokens)

Installation

npm install ensure-valid-token-middleware

Usage

import { ensureValidToken } from 'ensure-valid-token-middleware'

const secret = 'my-secret'

app.get('/protected-things/:id', ensureValidToken(secret), (req, res) => {
    res.send('Not much here, but you have a valid token')
})

Sample

Run the sample, note the hard coded secret (don't hard code secrets, this is just for demo purposes):

node sample

Try it with a valid token:

curl -H 'authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE4OTM0NTYwMDB9.qZwPGjUFZrnASQUwkIr6mremMqIScaTe8svva7SwFLA' localhost:3000/protected
