SubmitChallengePage Refactoring Documentation

Overview

The SubmitChallengePage has been refactored from a monolithic 540+ line component into a config-driven, scalable architecture with zero hardcoded conditional logic.

---

Architecture

1. Config-Driven Design

All topic-specific logic is now defined in /src/config/topicConfig.ts:

export interface TopicConfig {
  // ... existing fields
  mediaType: MediaType;              // "image" | "video" | "both"
  requiresTeammates: boolean;         // Show teammates section
  formComponent: ComponentType<SubmitFormProps>; // Dynamic form component
}

2. Component Structure

/src/app/components/
├── SubmitChallengePage.tsx          (60 lines - layout only)
└── submit-forms/
    ├── ImageForm.tsx                (Form for image-only topics)
    ├── ImageVideoForm.tsx           (Form for topics with both media types)
    └── shared/
        ├── MediaUploadBox.tsx       (Reusable upload component)
        ├── TeammatesSection.tsx     (Reusable teammates input)
        └── FormInput.tsx            (Reusable text input/textarea)

---

Key Components

SubmitChallengePage (Main Container)

Responsibilities:

• Layout (header, background, stars animation)
• Routing (useParams, navigate)
• Dynamic form rendering

Code:

const topicConfig = getTopicConfig(topicId);
const FormComponent = topicConfig.formComponent;

return (
  <Layout>
    <FormComponent 
      topicId={topicId} 
      topicTitle={topicConfig.title} 
      onSubmit={handleSubmit} 
    />
  </Layout>
);

Size: 60 lines (was 540+)

---

Form Components

1. ImageForm

Used by: Topics 1, 3, 4, 5, 6, 7, 8, 9

• Single image upload
• Teammates section (if requiresTeammates=true)
• Title & learnings inputs
• Submit button

2. ImageVideoForm

Used by: Topic 2 (نیمکت)

• Image/Video tab switcher
• Video requires cover image
• All other features from ImageForm

---

Shared Components

MediaUploadBox

Reusable upload component supporting:

• Image upload with preview
• Video upload with play icon overlay
• Required/optional states
• Custom labels
• Remove functionality

Props:

{
  type: "image" | "video",
  uploadedFile: string | null,
  onUpload: (e) => void,
  onRemove: () => void,
  fileName?: string,       // For videos
  label?: string,          // Custom label
  required?: boolean       // Required indicator
}

TeammatesSection

Dynamic teammate phone number inputs:

• Add/remove functionality
• Always maintains at least 1 input
• LTR direction for phone numbers

FormInput

Unified text input component:

• Single line or multiline (textarea)
• Consistent styling
• RTL support

How to Add a New Topic

Option 1: Use Existing Form

"10": {
  id: "10",
  title: "کتابخانه",
  // ... other fields
  mediaType: "image",
  requiresTeammates: false,
  formComponent: ImageForm,  // ← Use existing
  challenges: [...]
}

Option 2: Create Custom Form

1. Create /src/app/components/submit-forms/LibraryForm.tsx
2. Implement SubmitFormProps interface
3. Add to config:

import { LibraryForm } from "../app/components/submit-forms/LibraryForm";

"10": {
  formComponent: LibraryForm,  // ← Use custom
}

No changes needed to SubmitChallengePage!

Benefits

✅ Before vs After

Metric	Before	After
Lines	540+	60 (main) + forms
Conditionals	topicId === "2" everywhere	0
New Topic	Edit main file	Edit config only
Reusability	None	High
Testability	Hard	Easy

✅ Scalability

• Add topic: Update config (2 lines)
• Modify form: Edit specific form component
• Change layout: Edit SubmitChallengePage once

✅ Maintainability

• Single Responsibility Principle
• DRY (shared components)
• Clear separation of concerns

Migration Notes

Breaking Changes

None. All existing functionality preserved.

UI/UX Changes

None. Pixel-perfect match with original.

Behavior Changes

None. All animations, validations, and flows identical.

---

Future Enhancements

Easy to Add:

1. VideoForm - For video-only topics
2. NoMediaForm - For text-only submissions
3. MultiImageForm - For gallery uploads
4. ConditionalFields - Based on topic type

Example:

"11": {
  mediaType: "video",
  formComponent: VideoForm,  // Auto-handles video + cover
}

Testing

Unit Tests (Recommended)

describe('ImageForm', () => {
  it('calls onSubmit with correct data', () => {
    // Test form component in isolation
  });
});

describe('MediaUploadBox', () => {
  it('displays preview after upload', () => {
    // Test shared component
  });
});

Integration Tests

describe('SubmitChallengePage', () => {
  it('renders ImageForm for topic 1', () => {
    // Test dynamic rendering
  });
  
  it('renders ImageVideoForm for topic 2', () => {
    // Test config-driven behavior
  });
});
