📝 Walkthrough

Walkthrough

The change updates the router dependency, centralizes action schemas, adds response validation, extracts authentication instance creation, changes ALL handler wiring, relocates schema imports, and updates request and routing tests.

Changes

Authentication action schemas

Layer / File(s) Summary
Shared action schema definitions
packages/core/src/shared/schemas/actions.ts, packages/core/src/shared/schemas/general.ts
Shared schemas now define OAuth provider parameters, action responses, token payloads, callback parameters, and sign-out parameters.
Endpoint schema integration
packages/core/src/actions/*, packages/core/src/oauth/index.ts, packages/core/src/shared/oidc/*, packages/core/src/shared/utils/*, packages/core/src/validator/registry.ts, packages/core/src/@types/internal.ts
Authentication actions use shared parameter and response schemas. Schema imports move to shared modules.
Authentication instance factory and handler wiring
packages/core/src/createAuth.ts, packages/core/src/router/router.ts, packages/core/src/router/hooks.ts, packages/core/src/@types/config.ts, packages/core/package.json, packages/core/deno.json
Authentication instance construction moves into createAuthInstance. The Handlers type adds handle, and createAuth assigns it to ALL. Router dependency versions increase to ^0.11.0.
Request and routing test alignment
packages/core/test/actions/*, packages/core/test/instance.test.ts, packages/core/test/rate-limiter.test.ts
Affected requests now declare JSON content types. Unsupported methods now expect structured 404 responses.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to e0ebe

The router upgrade changes unsupported-method responses and requires an internal handler property in the public handler type. Existing integrations may receive different HTTP behavior or fail type checking, so these compatibility changes should be resolved or explicitly released as breaking changes before merge.

Keep handle out of the public Handlers type.

Handlers is exported and consumed by the Hono, Next, and React Router packages. The added required key breaks downstream object literals typed as Handlers. createAuthInstance returns the router handlers, and createAuth copies auth.handlers.handle to auth.handlers.ALL, so handle is an internal router entry point.

Define a separate internal handler type that includes handle. Expose only the HTTP method keys and ALL through Handlers and AuthInstance.

Pin the required Content-Type contract for JSON request bodies. signInCredentialsAction and updateSessionAction consume schema-validated ctx.body. In @aura-stack/router 0.11.0, a request without Content-Type produces null, fails body validation, and returns 422 before the action runs. Add a headerless JSON request case to both suites and assert 422.

Use the router metadata type instead of any.

OnErrorHook<Route, Meta> and OnRequestHook<Meta> both accept the declared arity in @aura-stack/router 0.11.0, so these annotations do not cause a generic-arity error. However, any removes type checking. Match the package’s RouterHooks signature by using EndpointMeta<any, any, any> for Meta.

handlers.ALL no longer returns 405 with an Allow header for unsupported methods.

The previous ALL handler dispatched GET, POST, PATCH, and DELETE, and returned 405 Method Not Allowed with Allow: GET, POST, PATCH, DELETE for every other method. ALL is now an alias of the router catch-all, so an unmatched method returns 404 with the ROUTER_FLOW/NOT_FOUND payload. The updated assertion in packages/core/test/instance.test.ts at Line 37 confirms this.

This changes the public HTTP contract of a shipped handler:

  • A PUT, OPTIONS, or HEAD request to an existing route reports that the route does not exist.
  • Clients lose the Allow header, so they cannot discover the supported methods.
  • Caches and API clients treat 404 and 405 differently.

The PR is scoped as a dependency upgrade. If the status change is intended, record it as a breaking change in the changelog. If it is not intended, keep the method allowlist in front of the router catch-all.

Line 32 also mutates the object returned by createAuthInstance after the double cast on Line 28. Returning the ALL alias from createAuthInstance would keep the assembly in one place.

🐛 Option: keep the 405 response for unsupported methods
-    auth.handlers.ALL = auth.handlers.handle
+    const allowedMethods = ["GET", "POST", "PATCH", "DELETE"] as const
+    auth.handlers.ALL = (request: Request) => {
+        const method = request.method.toUpperCase()
+        if (!allowedMethods.includes(method as (typeof allowedMethods)[number])) {
+            return new Response("Method Not Allowed", {
+                status: 405,
+                headers: { Allow: allowedMethods.join(", ") },
+            })
+        }
+        return auth.handlers.handle(request)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The test name still says 405, but the assertion expects 404.

Line 35 names the test "returns 405 for unsupported methods" and Line 37 asserts 404. Rename the test to match the behavior it proves. This assertion is the evidence for the handlers.ALL contract change flagged in packages/core/src/createAuth.ts at Line 32.

Lines 41-42 also assert the full router message text. That string belongs to @aura-stack/router and can change in any release. Asserting type and code keeps the test stable.

+        test("returns 404 for unsupported methods", async () => {

After reviewing the client API, I noticed an issue with how the router infers client endpoint configurations.

Currently, the router infers the endpoint configuration and schemas and marks fields such as params, searchParams, headers, and response as required based on the endpoint definition.

While params, searchParams, and headers should be required when they are defined by the endpoint, the response schema should not be required as part of the client request. The response schema describes the payload returned by the endpoint, not data that the client must provide.

Example Case

Endpoint Definition

The affected endpoint defines request schemas as well as a response schema:

const signInConfig = (oauth: OAuthProviderRecord) => {
return createEndpointConfig({
schemas: {
params: OAuthProviderListSchema(oauth),
searchParams: RedirectOptionsSchema,
response: SignInActionResponseSchema,
},
})
}
export const signInAction = (oauth: OAuthProviderRecord) => {
return createEndpoint(
"GET",
"/signIn/:oauth",
async (ctx) => {
const { toResponse } = await signIn(ctx.params.oauth, {
ctx: ctx.context,
request: ctx.request,
headers: ctx.request.headers,
redirect: ctx.searchParams.redirect,
redirectTo: ctx.searchParams.redirectTo,
})
return toResponse()
},
signInConfig(oauth)
)
}

Client API

Since params and searchParams are defined, the client should correctly require them:

const response = await client.get("/signIn/:oauth", {
  params: {
    oauth,
  },
  searchParams: {
    redirectTo,
    redirect: false,
  },
})

However, the response schema should not be included as a required field in the client request configuration. It represents the expected payload returned by the endpoint and should only be used for response type inference and validation.

This issue appears to be related to @aura-stack/router rather than the current library.

For that reason, this PR will remain stopped until the router issue is fixed and a new version containing the fix is released.
