    Flow-Like

    Flow-Like

    Strongly Typed Enterprise Scale Workflows

    ...The core idea is that UI components react to changes in upstream flows, making it easier to reason about how data moves through the system and how user interactions propagate changes throughout the interface. This approach contrasts with traditional two-way binding or manual update patterns by treating flows as the single source of truth, simplifying complex interactions and reducing bugs caused by scattered state logic. Developers can compose and combine flows, establish transformations, and orchestrate asynchronous events using intuitive primitives, resulting in code that is easier to test, maintain, and scale.
