Propro-auth-middleware is a Node.js authentication middleware for Express supporting server-side and client-side authentication with lazy loading, environment validation, and customizable options. Version 1.3.6 is the latest stable release. It is designed for applications needing robust authentication strategies. Differentiating features include dual-mode support and configuration flexibility, though it has a small user base and limited adoption compared to alternatives like Passport.js.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default
✓ const proproAuthMiddleware = require('propro-auth-middleware');
✗ import proproAuthMiddleware from 'propro-auth-middleware';
Package uses CommonJS and has no default export for ES modules.
proproAuthMiddleware
✓ const proproAuthMiddleware = require('propro-auth-middleware');
✗ const { proproAuthMiddleware } = require('propro-auth-middleware');
The module exports a single function directly, not as a named export.
proproAuthMiddleware
✓ const proproAuth = require('propro-auth-middleware');
✗ const auth = require('propro-auth-middleware').default;
There is no .default property; the require returns the function directly.

Express app with server-side authentication using custom validation and redirect on failure.

const express = require('express'); const proproAuthMiddleware = require('propro-auth-middleware'); const app = express(); const authOptions = { useServerAuth: true, serverOptions: { secret: process.env.SECRET || 'default_secret', authUrl: process.env.AUTH_URL || '', clientId: process.env.CLIENT_ID || '', clientSecret: process.env.CLIENT_SECRET || '', clientUrl: process.env.CLIENT_URL || '', redirectUri: process.env.REDIRECT_URI || '', onAuthFailRedirect: '/login', validateUser: async (userId) => { return userId === 'admin'; }, additionalChecks: async (req) => { return true; }, }, useClientAuth: false, }; app.use(proproAuthMiddleware(authOptions)); app.get('/', (req, res) => { res.send('Authenticated!'); }); app.listen(3000, () => console.log('Server running on port 3000'));
Debug
Known issues
gotchaMiddleware may fail silently if required environment variables (AUTH_URL, CLIENT_ID, CLIENT_SECRET) are not set.
fix
Ensure all required env vars are defined before initializing middleware.
affects: >=1.0.0
gotchaThe module uses CommonJS only; ES module import syntax will not work.
fix
Use require() instead of import statements.
affects: >=1.0.0
deprecatedPassing boolean arguments (e.g., proproAuthMiddleware(true, false)) is outdated; use options object instead.
fix
Use an object parameter: proproAuthMiddleware({ useServerAuth: true, useClientAuth: false }).
affects: >=1.1.0
gotchaThe 'secret' option defaults to 'RESTFULAPIs' which is insecure and may be overridden by environment variables.
fix
Explicitly set a strong secret via options or environment variable.
affects: >=1.0.0
Errors
Common errors & fixes
Error: Cannot find module 'propro-auth-middleware'
Package not installed or not in node_modules.
fix
Run 'npm install propro-auth-middleware' and ensure package.json includes it.
TypeError: proproAuthMiddleware is not a function
Incorrect import syntax; likely using ES module import.
fix
Use require('propro-auth-middleware') instead of import.
ReferenceError: SECRET is not defined
Environment variable not set or misspelled.
fix
Set SECRET in process.env or pass explicitly in options.
