# Introduction to Workflows
|
|
|
|
Welcome to the fourth lesson of the Mastra course! In this lesson, you'll learn about Mastra Workflows - a powerful way to orchestrate complex sequences of operations.
|
|
|
|
## What are Workflows?
|
|
|
|
Workflows in Mastra let you chain together multiple operations in a predictable, type-safe manner. Think of them as a recipe that breaks down complex tasks into smaller, manageable steps.
|
|
|
|
Instead of writing one big function that does everything, workflows let you:
|
|
|
|
- Break complex operations into smaller, reusable steps
|
|
- Define clear inputs and outputs for each step
|
|
- Chain steps together with automatic data validation
|
|
- Handle errors gracefully at each step
|
|
|
|
## Simple Example
|
|
|
|
Without workflows, you might write:
|
|
|
|
```typescript
|
|
async function processContent(text: string) {
|
|
// All logic in one function - hard to test and reuse
|
|
const validated = validateText(text);
|
|
const enhanced = enhanceText(validated);
|
|
const summarized = summarizeText(enhanced);
|
|
return summarized;
|
|
}
|
|
```
|
|
|
|
With workflows, the same logic becomes modular and reusable with tracing built in at every step.
|
|
|
|
```typescript
|
|
export const contentWorkflow = createWorkflow({...})
|
|
.then(validateStep)
|
|
.then(enhanceStep)
|
|
.then(summarizeStep)
|
|
.commit();
|
|
```
|
|
|
|
## What You'll Build
|
|
|
|
In this lesson, you'll create a content processing workflow that validates, enhances, and summarizes text content using multiple connected steps.
|
|
|
|
Let's start by understanding the basic building blocks!
