Ruby Reactor 0.4.0 is out — The saga pattern, production-ready.

🧊 Interrupts (pause & resume workflows)
📊 Web dashboard (inspect reactors live)
🧪 RSpec test helpers (test reactors in 3 lines)
🔒 Locks, semaphores, rate limits & periods
⚡ AsyncResult intermediate_results

[Artur Pañach @arturictus]

⚡ AsyncResult now exposes intermediate_results

Sync step results available immediately, even after the reactor goes async:

result.intermediate_results[:create_user]

No waiting for background jobs to finish.

[Artur Pañach @arturictus]

🔒 NEW: Coordination Primitives

with_lock — one runner at a time
with_semaphore — cap concurrency
with_rate_limit — multi-window quotas
with_period — once per day/month
All Redis-backed, composable. Smart snooze on contention.

[Artur Pañach @arturictus]

🧪 NEW: RSpec Test Helpers

test_reactor runs sync, auto-processes Sidekiq jobs, lets you mock steps:

mock_step(:charge) { Failure("declined") }

expect(subject).to have_run_step(:charge).after(:validate)

Testing async workflows in 3 lines.

[Artur Pañach @arturictus]

📊 NEW: Web Dashboard

Mount it in your routes to inspect every reactor — inputs, results, step-by-step trace, failures. No more grepping Sidekiq logs.

mount RubyReactor::Web => "/ruby_reactor"

Same feel as Sidekiq's dashboard, built for sagas.

[Artur Pañach @arturictus]

🧊 NEW: Interrupts — pause mid-flight, resume on webhooks.

interrupt :wait_for_webhook blocks until you call continue_by_correlation_id with a payload.

No polling. No split jobs. Native pause/resume in Ruby.

@mesa_eth I lost all my #USDT at the exchange when clicking on "Enable".
Is @mesa_eth a scam #DEX?
Luckily I was just trying with a small amount.
Can someone tell me what happened?
