# Breathing Exercise Types

Canonical page: https://docs.ovok.com/native-sdk/guide/components/breathing-exercise/types

The public barrel explicitly exports `BreathingExerciseContextType`. The component
props and animation prop shapes are used to type the exported components but are not
separate named exports from the module. The configuration type is also internal.

## Configuration shape [#configuration-shape]

```ts
type BreathingPattern = [
  { type: "inhale"; duration: number },
  { type: "hold"; duration: number },
  { type: "exhale"; duration: number },
];

type BreathingExercise = {
  methods: BreathingPattern;
  repeat: number;
  onFinish?: () => void;
};
```

The tuple is exactly three phases. Durations and repeat counts are numbers; the implementation does not document additional runtime validation, so validate user-provided values in the integrating app.

## Component props [#component-props]

`BreathingExerciseProps` is `ViewProps & BreathingExercise`. `BreathingExerciseAnimationProps` is `Omit<LottieViewProps, "source">`; the component always supplies its bundled source and animated progress.

## Context value [#context-value]

`BreathingExerciseContextType` contains the configuration and live state:

```ts
type BreathingExerciseContextType = BreathingExercise & {
  progress: SharedValue<number>;
  roundData: SharedValue<{
    method: BreathingExercise["methods"][number];
    animationProgress: number;
    remainingTime: number;
  }>;
  remainingTime: number;
  methodType: BreathingExercise["methods"][number]["type"];
};
```

`progress` and `roundData` are Reanimated shared values. Read them inside worklets for animated styles; use the React `remainingTime` and `methodType` values for ordinary text rendering.
