Streaming to frontend
We’re starting to build more workflows in Mastra (inside a Next.js app) and want to standardize how we handle front-end streaming so each new workflow doesn’t have to reinvent the logic.
We’re currently deciding between two approaches:
Directly streaming from Mastra, using its built-in event stream and snapshots (getSnapshot, etc.) for resume and progress updates.
Adding our own lightweight event-log layer, where our server listens to Mastra workflow events, stores them in a RunEvent table, and exposes an SSE endpoint for the front-end to consume.
Do you have any recommendations or best practices for teams standardizing streaming at scale with Mastra? For example—does Mastra plan to expose a public event stream API or recommend a pattern similar to the Playground?

Hey @wiz2202 ! Are you looking to have a single stream endpoint that emits events for all the running workflows? Just trying to better understand what you're trying to achieve 😉
