Inngest after work: durable event workflows in one evening

Why this matters after work

You searched for Inngest / event-driven workflows. After a full day of work, you do not need a full orchestration rewrite—you need a why-first path that fits one evening: understand the angle (durable steps triggered by events), run a hello-world mental model, and know what not to claim.

This hub article is educational only. Not investment advice. It will not pick stocks, size positions, or promise edge.

The evening angle

Tool focus: Inngest as durable event/step workflows for agents and apps. Some teams compare it to AWS Step Functions or LangGraph-style graphs—pick the metaphor that helps you learn, not a vendor war.

• Events kick off functions; steps can retry and resume
• Handy for after-work agent pipelines that must not lose state on a crash
• Still a learning tool tonight—not a production trading SLA
• Keep secrets in env vars; never hard-code keys in steps

Toy code (safe, synthetic)

# Shape only — follow current Inngest SDK docs; APIs move
print("Tonight: define ONE function with two steps")
print("Step 1: receive a synthetic event payload")
print("Step 2: sleep/retry stub, then print 'done' — no live brokers")

Confirm the language SDK, local dev server, and event schema in official docs before you deploy anything.

Practice loop (35–50 minutes)

1. Install the Inngest SDK + local/dev tooling in a throwaway project.
2. Define one function with two named steps (no real money APIs).
3. Send one synthetic event and watch the run complete in the dashboard/CLI.
4. Force a failure in step 2 once; observe retry/resume behavior.
5. Write three bullets: when durable steps help agents, when a simple queue is enough.

Pitfalls

• Treating a tutorial metric as a tradable signal.
• Wiring live broker or order APIs into a night-one workflow.
• Infinite retries without a budget or dead-letter plan.
• Confusing "durable" with "correct"—bad logic still persists.

What success looks like tonight

You can explain event → durable steps → retries in two sentences, show one successful run (and one retry), and list a "synthetic events only" rule. That is enough for an after-work session.

Next step

Tomorrow, add a third step or a fan-out event—still educational, still not investment advice.

Educational only. Not investment advice.

Extra checklist

• Prefer local/dev Inngest for night one.
• Name steps clearly; future-you will thank you.
• Time-box; one two-step function beats five unfinished graphs.
