Primitives

Dex gives you a small set of primitives. Compose them into a Flow that meets any complex business requirement.

• Flow — top-level durable program: Steps, Attributes, Channels, and RPCs
• Step — durable Steps run in the background with retries and more power
• Attribute — durable variables, with optional indexing, storage sync, and locking
• RPC — durable communication (Remote Procedure Call)
• Channel — durable message queue for internal and external communication
• Stream — best-effort resumable feed for low-latency UI updates
• Timer — durable timer
• SubFlow — start another Flow with hierarchical structure
• Client — APIs to operate Flow instances
