@clerk/backend is a Node.js package that provides backend functionality for authentication and user management. It allows developers to integrate user authentication, manage user sessions, and handle user data securely and efficiently.
What are @clerk/backend's main functionalities?
User Authentication
This feature allows you to authenticate users using a token. The code sample demonstrates how to verify a user's token and retrieve user information.
Auth0 is a flexible, drop-in solution to add authentication and authorization services to your applications. It provides a wide range of features including social login, multi-factor authentication, and user management. Compared to @clerk/backend, Auth0 offers more extensive integrations and a broader set of features but can be more complex to set up.
Firebase Admin SDK allows you to integrate Firebase services into your server-side applications. It provides functionalities for user authentication, database management, and cloud messaging. Compared to @clerk/backend, Firebase Admin SDK offers a more comprehensive suite of backend services but may require more configuration and setup.
Passport is an authentication middleware for Node.js that supports a wide range of authentication strategies. It is highly modular and can be integrated with various authentication providers. Compared to @clerk/backend, Passport is more flexible and customizable but requires more effort to implement and manage different authentication strategies.
This package provides Clerk Backend API resources and low-level authentication utilities for JavaScript environments. It is mostly used as the base for other Clerk SDKs but it can be also used on its own.
Features
Built for V8 isolates (Cloudflare Workers, Vercel Edge Runtime, etc...).
Make it isomorphic to work across all modern JS runtimes.
Use options injection for all keys and settings.
Support multiple CLERK_API_KEY for multiple instance REST access.
Align JWT key resolution algorithm across all environments (Function param > Environment variable > JWKS from API).
Tested automatically across different runtimes (Node, CF Workers, Vercel Edge middleware.)
Clean up Clerk interstitial logic.
Refactor the Rest Client API to return {data, errors} instead of throwing errors.
Export a generic verifyToken for Clerk JWTs verification.
Create Clerk SDK that includes an HTTP Rest client for the Backend API and session verification helpers. The clerk object contains the following APIs and methods:
importClerkfrom'@clerk/backend';
const clerk = Clerk({ apiKey: '...' });
await clerk.users.getUser('user_...');
// Available APIs
clerk.allowlistIdentifiers;
clerk.clients;
clerk.emailAddresses;
clerk.emails;
clerk.interstitial;
clerk.invitations;
clerk.organizations;
clerk.phoneNumbers;
clerk.redirectUrls;
clerk.sessions;
clerk.signInTokens;
clerk.smsMessages;
clerk.users;
// These functions should be used by framework-specific libraries, such as @clerk/nextjs or @clerk/remix.// Compute the authentication state given the request parameters.
clerk.authState(options);
// Build debug payload of the auth state.
clerk.debugAuthState(authState);
// Load clerk interstitial from this package
clerk.localInterstitial(options);
// Load clerk interstitial from the public Backend API endpoint
clerk.remotePublicInterstitial(options);
// Load clerk interstitial from the public Private API endpoint (Deprecated)
clerk.remotePrivateInterstitial(options);
