# Phase 2: Component Refactoring
|
|
|
|
## 🎯 Overview
|
|
|
|
Phase 2 focuses on breaking down large, repetitive form components into smaller, reusable pieces. This phase addresses code duplication, improves maintainability, and creates a consistent form component library.

|
|
```tsx
|
|
<div className="space-y-2">
|
|
<Label htmlFor="title">Title</Label>
|
|
<Controller
|
|
control={control}
|
|
name="title"
|
|
render={({ field }) => (
|
|
<Input
|
|
size="md"
|
|
type="text"
|
|
value={field.value}
|
|
onChange={field.onChange}
|
|
placeholder="Enter Title"
|
|
/>
|
|
)}
|
|
/>
|
|
{errors.title?.message && (
|
|
<p className="text-red-400 text-sm">{errors.title.message}</p>
|
|
)}
|
|
</div>
|
|
```
|
|
|
|
### **After (Reusable Component)**
|
|
```tsx
|
|
<FormField
|
|
control={form.control}
|
|
name="title"

|
|
- ✅ **Reduce code duplication** by 60-70%
|
|
- ✅ **Improve consistency** across all forms
|
|
- ✅ **Enhance maintainability** with centralized components
|
|
- ✅ **Speed up development** with ready-to-use components
