Introduction: The ‘Why’
Is your business logic a tangled mess of try-catch blocks and if-else statements? Do you find error handling, logging, and retries cluttering your core code?
What if you could refactor that complexity into a clean, chainable sequence of operations instead? A sequence that is a pleasure to express, read, and maintain?
This is the problem that Flow is designed to solve.
The Core Idea: Recipe and Chef
Flow is built on a simple analogy:
- A Flow is a recipe; an immutable, declarative blueprint that describes the steps in your process.
- The
FlowEngineis the chef; it takes your recipe and executes it, handling the messy details ofasyncoperations and exceptions.
This separation of concerns is the key to writing code that is easier to read, test, and reuse.
