Define Complex Tasks Step by Step with Mastra Workflows

​Not everything should be left to an agent's reasoning. When you know the steps, the order, and the data that needs to flow between them, you want control — not inference. That's what Mastra workflows give you.

​Workflows let you define structured sequences of tasks with typed inputs and outputs, branching, parallel execution, loops, suspend and resume, and streaming — all in TypeScript. You get the predictability of a pipeline with the flexibility to call agents, tools, or external APIs from any step. Whether you're building a multi-step RAG pipeline, a human-in-the-loop approval flow, or a data processing job, workflows give you fine-grained control over what runs, when, and how data moves between steps.

​In this workshop, you'll learn how to build workflows from scratch and compose them into real applications.

​You'll learn how to:

• ​Create steps with typed input and output schemas using createStep()

• ​Chain, branch, parallelize, and loop steps with .then(), .branch(), .parallel(), .foreach(), .dountil(), and .dowhile()

• ​Map data between steps when schemas don't align

• ​Suspend and resume workflows for human-in-the-loop or async callbacks

• ​Nest workflows inside other workflows for reusable, composable pipelines

• ​Stream workflow execution and inspect runs in Mastra Studio

​Q&A throughout and at the end.
