Lifecycle

As explained in Web Components in Action

A Unity component lifecycle is the sequence of phases and callbacks governing a component in the Unity game engine.

A component lifecycle is the sequence of phases and callbacks that governs a component. Unity appears as a comparison point for understanding how component-based systems organize these stages, but the available treatment does not specify Unity callbacks. section 4.1

Lifecycle comparisons can focus on these distinctions:

  • React groups lifecycle methods into mounting, updating, unmounting, and error handling. section 4.4
  • React uses error boundaries to isolate failures within components, while Web Components provide no directly similar lifecycle method. section 4.4
  • Web Components favor a smaller lifecycle surface that developers can extend with their own code, libraries, or microframeworks. section 4.4

How Web Components in Action covers it

How deep it goes
Explains React’s four lifecycle categories and error boundaries, but stops short of specifying Unity phases or callbacks.
Examples
Uses React’s lifecycle categories, error boundaries, and pre-version-16 application unmounting as comparison examples.
What you can do after
Evaluate lifecycle designs by comparing their phases, error handling, and extensibility.
How it connects
Connects lifecycle to Web Components, React, mounting, updating, unmounting, error handling, and error boundaries.
