IsReady

IsReady is a common naming convention in software design for indicating that an object, component, or resource has completed its initialization and is prepared to perform its primary functions. In code, it typically refers to a boolean indicator, either as a property named IsReady or as a method named isReady(), which returns true when prerequisites are satisfied and resources are available.

Readiness often depends on dependencies being initialized, data being loaded, permissions being granted, or a network connection being established. The check is used to guard operations that should only run once the system is in a stable state, and it is frequently part of initialization sequences, state machines, or lifecycle management.

Common implementation patterns include polling a function or property until it reports true, subscribing to a ready or initialized event, or using promise, future, or callback-based workflows in asynchronous environments. Design choices include whether isReady should be idempotent and how to handle transitions to and from the ready state.

Language and framework conventions vary. In Java and C#-style languages, a boolean method or property is typically named isReady or IsReady. In JavaScript and TypeScript, isReady might be a method, a boolean getter, or part of a larger lifecycle object.

Applications span user interfaces that should render only after data loads, services that wait for a handshake, hardware devices reporting readiness, and data pipelines that transition to processing when all inputs are available.

Potential issues include stale or inconsistent readiness due to racing conditions, over-reliance on a single isReady check instead of a formal state machine, and performance costs if readiness checks are expensive. Clear state transitions and timeouts help mitigate these risks. See also readiness and lifecycle.
