May 2025 Summaries

The Inngest team has released a new developer preview called Realtime, which allows developers to stream updates from their Inngest functions to users in real-time. This feature is particularly useful for long-running tasks and enables bi-directional communication between users and Ingest functions through the use of channels and topics. The `publish()` method is available in the Ingest TypeScript and Go SDKs, providing a flexible and fully typed Realtime API. Developers can subscribe to channels using the `useInngestSubscription()` hook from React components or by directly subscribing from the server using the `subscribe()` function. Realtime updates are built upon Ingest's protocol, ensuring secure, low-latency, and at-most-once delivery of messages. The feature is already available as a developer preview in the Ingest TypeScript and Go SDKs, with some details subject to change during this period.

The Fetch API is a new set of APIs introduced by Inngest, allowing developers to make durable HTTP requests within an Inngest function. This enables offloading of third-party API requests and data fetching to the Inngest Platform, saving compute and improving reliability. The `step.fetch()` API brings benefits similar to `step.run()`, but with the added advantage of offloading HTTP requests, removing potential serverless timeout issues. It is also compatible with the `Promise` API, enabling parallel processing of multiple requests. Additionally, the `fetch()` utility provides a way to make third-party library HTTP requests durable, while all `step.fetch()` and `fetch()` calls appear in Inngest Traces for improved observability.
