Inngest
Definition
Inngest organizes multi-step workflows with stored step results and retries.
Inngest is a platform for persistent execution of functions and workflows. Individual steps are executed separately; stored results allow resuming a workflow after errors.
Simply explained
Like a task list with checked intermediate steps. The list can continue the workflow but does not automatically undo a double-triggered external payment.
Why it matters in practice
When introducing it, special attention should be paid to side effects of repeated external calls.
Example from business
Possible example: After receiving an order, a workflow processes documents and then sends an internal notification.
Limits and pitfalls
- Retries can trigger an external call twice if its response is lost. Such calls may require idempotency keys, i.e., identifiers to avoid duplicate execution.
Origin & history
The product documentation classifies Inngest under persistent execution, functions, and stored step results.
Use in mid-sized companies
- Potential application areas are document processes and internal approvals; before use, retries and external side effects would be specifically tested.
Frequently asked questions
Is the entire workflow always repeated?
Already stored steps can be reused.
Does the platform prevent every duplicate external effect?
No, the documentation explicitly points out this risk with retries.
