It describes the limitations of the Genkit Developer UI when flows need Firebase services such as Firestore or Cloud Storage, and presents the Firebase Local Emulator Suite as a way to simulate those services for local testing. ### Source excerpt AIHow to Develop Genkit Flows Genkit includes a powerful tool called the Genkit Developer UI that can significantly accelerate the development of Genkit Flows by enabling local testing. However, when integrating with other Firebase products, such as Firestore or Cloud Storage, the Genkit Developer UI may not be sufficient. In this article, I'll walk you through how to enhance your local testing environment by integrating the Firebase Local Emulator Suite to test Genkit Flows more effectively. Genkit Developer UI The Genkit Developer UI is an essential tool that allows you to verify the behavior of Genkit Flows locally before deploying them. (It has a great UI, and it's super exciting to use!!) While the Genkit Developer UI provides a fantastic developer experience, it does have some limitations. The Limitation The challenge comes when you need to integrate other Firebase products. For example, when you create a configuration where Genkit communicates with Firestore, such as the one I discussed in my previous article, "8 Genkit Architectures to Orchestrate Firebase & AI". To clarify this, let's look at two cases. Working with self-contained flowsOK case In this case, the entire processing is self-contained within Genkit, with no need to integrate Firebase products like Firestore or Cloud Storage, so you can run everything locally using the Genkit Developer UI. export const firebaseAuthFlow = onFlow( ai, { name: `firebaseAuthFlow`, outputSchema: z.string(), authPolicy: firebaseAuth((user) => { if (user.firebase?.sign_in_provider !== `anonymous`) { throw new Error(`Only anonymously authenticated users can access this function`) } }), httpsOptions: { secrets: [googleAIapiKey], cors: true, }, }, async () => {} ) Even though this function uses authPolicy with Firebase Authentication, Genkit Developer UI allows you to inject an authentication provider, so local testing is still possible. Working with Flows that require Firebase servicesFurther testing required case In this ## Firebase App Hosting adds a local emulator and other deployment features DevFeed: [Firebase App Hosting adds a local emulator and other deployment features]() Original publisher: [Read original article]() Author: Julia Reid; James Daniels Published: 2024-12-19T00:00:00Z Content type: news Language: en Sources: [Firebase Blog]() Topics: [Firebase](), [hosting](), [Serverless](), [Cloud Run](), [Angular](), [Next.js]() Tags: [angular](), [app-hosting](), [ci-cd](), [debugging](), [deployment](), [emulator](), [emulator-suite](), [firebase](), [hosting](), [monorepo](), [next](), [next-js](), [ssr](), [vpc]() ### AI overview Firebase's end-of-year update describes new and recently added Firebase App Hosting features, including a local emulator, improved build-debugging UI, VPC connectivity, wildcard domains, additional regions, monorepo support, manual rollouts, and cookie support. ### Source excerpt News, tutorials, and updates from the Firebase team. ## Announcing cross-service Security Rules DevFeed: [Announcing cross-service Security Rules]() Original publisher: [Read original article]() Author: Shruti Padamata Published: 2022-09-28T00:00:00Z Content type: release Language: en Sources: [Firebase Blog]() Topics: [Firebase](), [Security](), [Firestore](), [Cloud]() Tags: [cloud-storage](), [emulator-suite](), [feature](), [firebase](), [firebase-cli](), [firestore](), [security](), [security-rules]() ### AI overview Firebase announces cross-service Security Rules for Cloud Storage, allowing rules to query Firestore data in the same Firebase project. ### Source excerpt We're excited to deliver one of the most popular feature requests for Security Rules.
