Dependency injection
Passing configuration and credentials into a workflow from outside rather than hardcoding them. Makes workflows portable across environments the same workflow runs in staging and production by swapping the injected credentials, not editing the code.
Expert insight
Dependency injection (passing in a configuration or connection rather than hardcoding it inside a workflow step) is what makes the same workflow logic reusable across different environments or clients without modifying the workflow itself, hardcoded dependencies mean every new environment requires editing the workflow directly.
In a real workflow
The email provider is passed into a sub-workflow as a parameter, so tests can use a fake provider.
Common mistakes
- Over-engineering simple workflows.
- Hidden dependencies that are hard to swap.
