Why Context?
Goal: Share values (theme, user, locale) across the tree without prop drilling.
- Create a Context
- Wrap with a Provider
- Read via useContext
Prop drilling explained
Prop drilling = passing props through layers that don’t need them. It clutters code and makes refactors harder.
Demo: ThemeContext basics
Create a ThemeContext, provide theme at the top, and read it deep in the tree with useContext.
<div id="root"></div>
Tips & scope
Tips:
- Keep context values small (e.g., theme, user object, small actions).
- Wrap only where needed to keep rerenders local.
- Name Provider and hook clearly (e.g., ThemeProvider, useTheme).
Demo: useTheme helper hook
Create a small useTheme hook to avoid importing the context everywhere; it just calls useContext internally.
<div id="root"></div>
Limits & gotchas
Avoid Context for:
- Highly dynamic, frequently changing values that cause many re-renders.
- Local state used by a single component.
- Very large objects—pass only what children need.
Context purpose check
Recap
Recap: Create a context, provide a value near the top, and read it with useContext (or a helper hook) deep in the tree to avoid repetitive props.
