Unlock React Power: Master Higher‑Order Components and Their Two Core Patterns

Higher‑Order Component (HOC) is an advanced React pattern that takes a component and returns a new component, enabling reuse of component logic.

There are two main HOC implementations: a props‑proxy (attribute delegation) and reverse inheritance (extending the original component).

Example of a props‑proxy HOC is Ant Design’s Form.create(), which injects a form prop into the wrapped component, allowing the parent to capture form values and handle submission.

Example of a reverse‑inheritance HOC is a loading wrapper that accesses the wrapped component’s internal loading state to display a UI overlay.

When using reverse inheritance, the subclass constructor runs before the original component’s constructor, and lifecycle methods defined in the HOC can be overridden by the wrapped component unless explicitly preserved, so developers may need to hijack lifecycle methods to retain desired behavior.

Advantages of reverse‑inheritance HOCs over props‑proxy include the ability to access or modify the wrapped component’s state, hijack its lifecycle, and perform render interception.
