Next.js Best Practices

Learn how to use best practices for building Next.js Applications

1

Problem 1: Too Many Boolean Props

The classic issue - components with dozens of boolean flags

Solutions:

Solution 1: Variant Pattern

Use a single variant prop instead of multiple booleans

Solution 2: Composition Pattern

Break into smaller, focused components

Solution 3: Config Object

Group related props into a single configuration object

Solution 4: Compound Components

Use the builder pattern for flexible composition

2

Problem 2: Prop Drilling

Passing props through multiple levels of components

3

Problem 3: Conflicting Props

Props that contradict each other

4

Problem 4: Callback Hell

Too many callback/handler props

5

Problem 5: Spread Props Anti-pattern

Spreading unknown props without control

6

Problem 6: State vs Props Confusion

Props that should be internal state

7

Problem 7: Prop Coupling

Props that must be used together

8

Problem 8: Type Safety Issues

Unclear prop types and combinations

9

Problem 9: Server Actions vs Client Handlers

Mixing server actions with client-side handlers

10

Problem 10: Hook Prop Drilling

Passing hook results through props instead of using hooks directly

11

Problem 11: Async Props

Handling async data in props instead of using Server Components

12

Problem 12: Custom Hooks Over Props

Extracting logic into custom hooks instead of prop drilling

Best Practice Recommendation

The Composition Pattern + Variant Pattern combination is the most flexible and maintainable approach. It provides:

Clear separation of concerns
Easy to extend without prop explosion
Better TypeScript support
Improved component reusability
Easier testing and documentation
