feat(backend,nextjs): Introduce machine authentication

+
+Introduces machine authentication, supporting four token types: `api_key`, `oauth_token`, `machine_token`, and `session_token`. For backwards compatibility, `session_token` remains the default when no token type is specified. This enables machine-to-machine authentication and use cases such as API keys and OAuth integrations. Existing applications continue to work without modification.
+
+You can specify which token types are allowed by using the `acceptsToken` option in the `authenticateRequest()` function. This option can be set to a specific type, an array of types, or `'any'` to accept all supported tokens.
+
+Example usage:
+
+```ts
+import express from 'express';
+import { clerkClient } from '@clerk/backend';
+
+const app = express();
+
+app.use(async (req, res, next) => {
+ const requestState = await clerkClient.authenticateRequest(req, {
+ acceptsToken: 'any'
+ });
+
+ if (!requestState.isAuthenticated) {
+ // do something for unauthenticated requests
+ }
+
+ const authObject = requestState.toAuth();
+
+ if (authObject.tokenType === 'session_token') {
+ console.log('this is session token from a user')
+ } else {
+ console.log('this is some other type of machine token')
+ console.log('more specifically, a ' + authObject.tokenType)
+ }
+
+ // Attach the auth object to locals so downstream handlers
+ // and middleware can access it
+ res.locals.auth = authObject;
+ next();
+});
+```

+Machine authentication is now supported for advanced use cases via the backend SDK. You can use `clerkClient.authenticateRequest` to validate machine tokens (such as API keys, OAuth tokens, and machine-to-machine tokens). No new helpers are included in these packages yet.
+
+Example (Astro):
+
+```ts
+import { clerkClient } from '@clerk/astro/server';
+
+export const GET: APIRoute = ({ request }) => {
+ const requestState = await clerkClient.authenticateRequest(request, {

+
+ if (!requestState.isAuthenticated) {
+ return new Response(401, { message: 'Unauthorized' })

+Introduces machine authentication, supporting four token types: `api_key`, `oauth_token`, `machine_token`, and `session_token`. For backwards compatibility, `session_token` remains the default when no token type is specified. This enables machine-to-machine authentication and use cases such as API keys and OAuth integrations. Existing applications continue to work without modification.

+You can specify which token types are allowed by using the `acceptsToken` option in the `authenticateRequest()` function. This option can be set to a specific type, an array of types, or `'any'` to accept all supported tokens.

+
+Introduces machine authentication, supporting four token types: `api_key`, `oauth_token`, `machine_token`, and `session_token`. For backwards compatibility, `session_token` remains the default when no token type is specified. This enables machine-to-machine authentication and use cases such as API keys and OAuth integrations. Existing applications continue to work without modification.
+
+You can specify which token types are allowed for a given route or handler using the `acceptsToken` property in the `auth()` helper, or the `token` property in the `auth.protect()` helper. Each can be set to a specific type, an array of types, or `'any'` to accept all supported tokens.
+
+Example usage in Nextjs middleware:
+
+```ts
+import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server';
+
+const isOAuthAccessible = createRouteMatcher(['/oauth(.*)'])
+const isApiKeyAccessible = createRouteMatcher(['/api(.*)'])
+const isMachineTokenAccessible = createRouteMatcher(['/m2m(.*)'])
+const isUserAccessible = createRouteMatcher(['/user(.*)'])
+const isAccessibleToAnyValidToken = createRouteMatcher(['/any(.*)'])
+
+export default clerkMiddleware(async (auth, req) => {
+ if (isOAuthAccessible(req)) await auth.protect({ token: 'oauth_token' })
+ if (isApiKeyAccessible(req)) await auth.protect({ token: 'api_key' })
+ if (isMachineTokenAccessible(req)) await auth.protect({ token: 'machine_token' })
+ if (isUserAccessible(req)) await auth.protect({ token: 'session_token' })
+
+ if (isAccessibleToAnyValidToken(req)) await auth.protect({ token: 'any' })
+});
+
+export const config = {
+ matcher: [
+ '/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)',
+ '/(api|trpc)(.*)',
+ ],
+}
+```
+
+Leaf node route protection:
+
+```ts
+import { auth } from '@clerk/nextjs/server'
+
+// In this example, we allow users and oauth tokens with the "profile" scope
+// to access the data. Other types of tokens are rejected.
+function POST(req, res) {
+ const authObject = await auth({ acceptsToken: ['session_token', 'oauth_token'] })
+
+ if (authObject.tokenType === 'oauth_token' &&
+ !authObject.scopes?.includes('profile')) {
+ throw new Error('Unauthorized: OAuth token missing the "profile" scope')
+ }
+
+ // get data from db using userId
+ const data = db.select().from(user).where(eq(user.id, authObject.userId))
+
+ return { data }
+}
+```
