Local emulators. Real API contracts. Part of Mockingbird.

OAuth authorize, token exchange, userinfo, OIDC discovery, Graph /me, logout, token revocation. Runs through Mockingbird's portable Fetch runtime with SQLite persistence, namespaces, checkpoints, faults and admin controls.

#Install

npm install @crvouga/mockingbird-service-microsoft

#Usage

import { AuthenticationHandler, Client, type Context } from "@microsoft/microsoft-graph-client"
import { createRuntime } from "@crvouga/mockingbird-service-microsoft"

// The Microsoft Graph SDK your application already uses. Only the last middleware changes:
// requests reach the emulator in this process instead of graph.microsoft.com.
const emulator = createRuntime({ seed: 1 })
const graph = Client.initWithMiddleware({
  middleware: [
    new AuthenticationHandler({ getAccessToken: async () => "mock_access_token" }),
    {
      execute: async (context: Context) => {
        context.response = await emulator.fetch(new Request(context.request, context.options))
      },
    },
  ],
})

const me = await graph.api("/me").get()
console.log(me.displayName, me.mail) // Test User testuser@outlook.com

For sign-in, serve the emulator (createServer from /server) and give your OpenID Connect client the issuer <server.url>/9188040d-6c67-4c5b-b112-36a304b66dad/v2.0 (the default tenant).

#API

• MicrosoftAPI: portable provider instance; accepts SQLite, namespace, clock, fixtures and baseUrl.
• createRuntime: shared runtime, including native namespace and checkpoint controls.
• MICROSOFT_NAMESPACE: default storage namespace.
• document, operationIds, supportedOperationIds: registered provider route inventory.
• createServer, DEFAULT_PORT, serveTarget from /server: loopback listener and CLI configuration.

fixtures accepts synthetic provider seed records. reset() restores defaults. Emulate 0.12.1 is a test oracle only, never a runtime dependency. Vendor handlers ported under Apache-2.0 retain their license and attribution; see LICENSE_EMULATE and THIRD_PARTY_NOTICES.md.
