# Web App Architecture Analysis & Modularity Assessment
|
||||
|
||||
**Date:** September 4, 2025
|
||||
**Project:** Ario Web App (Vue 3 + Nostr + LNbits)
|
||||
**Objective:** Evaluate current architecture for modular plugin-based development
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The current web application demonstrates solid foundational architecture with excellent Nostr infrastructure (RelayHub/NostrclientHub) but lacks true modularity for plugin-based development.
|
||||
|
||||
**Overall Modularity Rating: 6.5/10**
|
||||
|
||||
The app successfully implements core Nostr functionality and component organization but requires significant architectural refactoring to achieve the stated objective of independent, pluggable feature modules.
|
||||
|
||||
---
|
||||
|
||||
## Current Architecture Assessment
|
||||
|
||||
### ✅ Strengths (What's Working Well)
|
||||
|
||||
#### 1. Strong Base Infrastructure (8/10)
|
||||
- **RelayHub & NostrclientHub**: Excellent centralized Nostr infrastructure with robust connection management, event handling, and browser compatibility
|
||||
- **Pinia Stores**: Clean state management separation (`nostr.ts`, `market.ts`) with reactive patterns
|
||||
- **Composables Pattern**: Good reactive logic encapsulation (`useRelayHub`, `useNostrChat`, `useMarket`)
|
||||
- **UI Component Library**: Well-structured Shadcn/ui components with consistent design system
|
||||
|
||||
#### 2. Component Organization (7/10)
|
||||
- Components grouped by domain (`/market`, `/nostr`, `/events`, `/auth`)
|
||||
- Page-level routing with lazy loading implementation
|
||||
- Composables provide reusable business logic across components
|
||||
- Clean separation of concerns between UI and business logic
|
||||
|
||||
#### 3. Service Layer (6/10)
|
||||
- Clean service abstractions (`nostrmarketService`, `paymentMonitor`)
|
||||
- API layer separation (`/lib/api`)
|
||||
- Type-safe interfaces and proper error handling
|
||||
|
||||
### ❌ Critical Issues (What's Missing)
|
||||
|
||||
#### 1. No Plugin Architecture (3/10)
|
||||
- **Hard-coded routes**: All features baked into main router configuration
|
||||
- **Tight coupling**: Components directly import across modules without abstraction
|
||||
- **No feature isolation**: Cannot develop/deploy components independently
|
||||
- **No plugin registration system**: Missing infrastructure for dynamic feature loading
|
||||
|
||||
#### 2. Cross-Module Dependencies (4/10)
|
||||
|
||||
**Examples of problematic tight coupling:**
|
||||
```typescript
|
||||
// Payment monitor importing market types directly
|
||||
src/lib/services/paymentMonitor.ts: import type { Order } from '@/stores/market'
|
||||
|
||||
// Navbar importing chat composable directly
|
||||
src/components/layout/Navbar.vue: import { nostrChat } from '@/composables/useNostrChat'
|
||||
|
||||
// Services importing market store directly
|
||||
src/lib/services/nostrmarketService.ts: import type { Stall, Product, Order } from '@/stores/market'
|
||||
```
|
||||
|
||||
#### 3. Missing Module Boundaries (5/10)
|
||||
- No clear module interfaces/contracts
|
||||
- Shared types scattered across modules without centralized definition
|
||||
- No dependency injection system for service management
|
||||
- Missing module lifecycle management
|
||||
|
||||

|
||||
|
||||
## Required Changes for Modular Architecture
|
||||
|
||||
### Phase 1: Core Infrastructure Refactor
|
||||
|
||||
#### 1. Create Module System
|
||||
```typescript
|
||||
// /src/modules/base/types.ts
|
||||
interface ModuleConfig {
|
||||
name: string
|
||||
routes: RouteConfig[]
|
||||
components: ComponentConfig[]
|
||||
services: ServiceConfig[]
|
||||
dependencies?: string[]
|
||||
}
|
||||
|
||||
interface ModulePlugin {
|
||||
install(app: App, options?: any): void
|
||||
uninstall(): void
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. Plugin Registration System
|
||||
```typescript
|
||||
// /src/core/plugin-manager.ts
|
||||
class PluginManager {
|
||||
private plugins = new Map<string, ModulePlugin>()
|
||||
|
||||
register(module: ModulePlugin): void
|
||||
unregister(name: string): void
|
||||
getModule(name: string): ModulePlugin
|
||||
getDependencies(name: string): string[]
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 2: Module Extraction
|
||||
|
||||
#### 1. Base Module Structure
|
||||
```
|
||||
/src/modules/base/
|
||||
├── nostr/
|
||||
│ ├── relayHub.ts # Centralized relay management
|
||||
│ ├── nostrclientHub.ts # Client connection handling
|
||||
│ └── types.ts # Nostr-specific types
|
||||
├── auth/
|
||||
│ ├── lnbits.ts # LNbits authentication
|
||||
│ └── composables/
|
||||
├── pwa/
|
||||
│ ├── install-prompt.ts
|
||||
│ └── notifications.ts
|
||||
└── ui/ # Shadcn components
|
||||
```
|
||||
|
||||
#### 2. Feature Modules
|
||||
```
|
||||
/src/modules/
|
||||
├── nostr-feed/
|
||||
│ ├── components/
|
||||
│ │ └── NostrFeed.vue
|
||||
│ ├── composables/
|
||||
│ │ └── useFeed.ts
|
||||
│ ├── services/
|
||||
│ │ └── feedService.ts
|
||||
│ └── index.ts # Module export
|
||||
├── market/
|
||||
│ ├── components/
|
||||
│ ├── composables/
|
||||
│ ├── stores/
|
||||
│ ├── services/
|
||||
│ └── index.ts
|
||||
├── chat/
|
||||
└── events/
|
||||
```
|
||||
|
||||
#### 3. Module Interface Standards
|
||||
```typescript
|
||||
// Each module exports standardized interface
|
||||
export interface NostrFeedModule extends ModulePlugin {
|
||||
name: 'nostr-feed'
|
||||
components: {
|
||||
NostrFeed: Component
|
||||
}
|
||||
routes: RouteConfig[]
|
||||
dependencies: ['base']
|
||||
config?: NostrFeedConfig
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 3: Event-Driven Communication
|
||||
|
||||
#### Replace Direct Imports with Event Bus
|
||||
```typescript
|
||||
// /src/core/event-bus.ts
|
||||
interface ModuleEventBus {
|
||||
emit(event: string, data: any): void
|
||||
on(event: string, handler: Function): void
|
||||
off(event: string, handler: Function): void
|
||||
}
|
||||
|
||||
// Example usage:
|
||||
// Market module: eventBus.emit('order:created', order)
|
||||
// Chat module: eventBus.on('order:created', handleNewOrder)
|
||||
```
|
||||
|
||||
#### Dependency Injection Container
|
||||
```typescript
|
||||
// /src/core/di-container.ts
|
||||
class DIContainer {
|
||||
provide<T>(token: string, instance: T): void
|
||||
inject<T>(token: string): T
|
||||
|
||||
// Module-scoped injection
|
||||
provideForModule(module: string, token: string, instance: any): void
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Recommended Ground-Up Architecture
|
||||
|
||||
If rebuilding from scratch, implement these architectural patterns:
|
||||
|
||||
### 1. Module-First Architecture
|
||||
```
|
||||
src/
|
||||
├── core/ # Base app infrastructure
|
||||
│ ├── plugin-manager.ts # Plugin registration & lifecycle
|
||||
│ ├── di-container.ts # Dependency injection
|
||||
│ ├── event-bus.ts # Inter-module communication
|
||||
│ ├── module-registry.ts # Module discovery & loading
|
||||
│ └── base-services/ # Core services
|
||||
├── modules/
|
||||
│ ├── base/ # Core functionality (required)
|
||||
│ │ ├── nostr/ # RelayHub, NostrclientHub
|
||||
│ │ ├── auth/ # LNbits authentication
|
||||
│ │ ├── pwa/ # Progressive Web App features
|
||||
│ │ └── ui/ # Shadcn component library
|
||||
│ ├── nostr-feed/ # Announcements & social feed
|
||||
│ ├── market/ # Marketplace functionality
|
||||
│ ├── chat/ # Nostr chat implementation
|
||||
│ └── events/ # Event ticketing system
|
||||
└── app.ts # Application composition & startup
|
||||
```
|
||||
|
||||
### 2. Configuration-Driven Setup
|
||||
```typescript
|
||||
// /src/app.config.ts
|
||||
export const appConfig = {
|
||||
modules: {
|
||||
base: {
|
||||
required: true,
|
||||
nostr: {
|
||||
relays: process.env.VITE_NOSTR_RELAYS
|
||||
}
|
||||
},
|
||||
'nostr-feed': {
|
||||
enabled: true,
|
||||
config: {
|
||||
refreshInterval: 30000,
|
||||
maxPosts: 100
|
||||
}
|
||||
},
|
||||
market: {
|
||||
enabled: true,
|
||||
config: {
|
||||
defaultCurrency: 'sats',
|
||||
paymentTimeout: 300000
|
||||
}
|
||||
},
|
||||
chat: {
|
||||
enabled: false // Can be toggled via config
|
||||
},
|
||||
events: {
|
||||
enabled: true,
|
||||
config: {
|
||||
ticketValidationEndpoint: '/api/tickets/validate'
|
||||
}
|
||||
}
|
||||
},
|
||||
features: {
|
||||
pwa: true,
|
||||
pushNotifications: true,
|
||||
electronApp: true
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Dynamic Module Loading
|
||||
```typescript
|
||||
// /src/core/module-loader.ts
|
||||
class ModuleLoader {
|
||||
async loadModule(name: string): Promise<ModulePlugin> {
|
||||
const module = await import(`@/modules/${name}/index.ts`)
|
||||
await this.resolveDependencies(module.dependencies || [])
|
||||
return module.default
|
||||
}
|
||||
|
||||
async unloadModule(name: string): Promise<void> {
|
||||
const module = this.getModule(name)
|
||||
if (module) {
|
||||
await module.uninstall()
|
||||
this.cleanupRoutes(name)
|
||||
this.cleanupServices(name)
|
||||
}
|
||||
}
|
||||
|
||||
private async resolveDependencies(deps: string[]): Promise<void> {
|
||||
for (const dep of deps) {
|
||||
if (!this.isModuleLoaded(dep)) {
|
||||
await this.loadModule(dep)
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Module Development Workflow
|
||||
```bash
|
||||
# Develop single module in isolation
|
||||
npm run dev:module market
|
||||
|
||||
# Test module independently
|
||||
npm run test:module market
|
||||
|
||||
# Build specific modules only
|
||||
npm run build:modules market,chat
|
||||
|
||||
# Hot reload module during development
|
||||
npm run dev:hot-module nostr-feed
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Key Architectural Improvements
|
||||
|
||||
### 1. Dependency Inversion
|
||||
- Modules depend on interfaces, not concrete implementations
|
||||
- Services injected via DI container rather than direct imports
|
||||
- Clear separation between module contracts and implementations
|
||||
|
||||
### 2. Event-Driven Communication
|
||||
- Replace direct imports with event-based messaging
|
||||
- Loose coupling between modules via standardized events
|
||||
- Centralized event routing and handling
|
||||
|
||||
### 3. Module Lifecycle Management
|
||||
- Proper setup and teardown hooks for each module
|
||||
- Resource cleanup when modules are disabled/unloaded
|
||||
- Dependency resolution during module loading
|
||||
|
||||
### 4. Configuration Over Code
|
||||
- Enable/disable features via configuration files
|
||||
- Runtime module toggling without code changes
|
||||
- Environment-specific module configurations
|
||||
|
||||
### 5. Hot Module Replacement
|
||||
- Develop modules independently without full app restart
|
||||
- Live reloading of individual modules during development
|
||||
- Isolated testing environments for each module
|
||||
|
||||
---
|
||||
|
||||
## Implementation Roadmap
|
||||
|
||||
### High Priority (Immediate)
|
||||
1. ✅ **Extract RelayHub/NostrclientHub to base module** (mostly complete)
|
||||
2. **Create plugin registration system** - Core infrastructure for module loading
|
||||
3. **Convert nostr-feed to plugin pattern** - Proof of concept implementation
|
||||
|
||||
### Medium Priority (Phase 2)
|
||||
4. **Implement event bus communication** - Replace direct imports between modules
|
||||
5. **Add module lifecycle management** - Proper setup/teardown hooks
|
||||
6. **Create development tooling** - Scripts for isolated module development
|
||||
|
||||
### Low Priority (Phase 3)
|
||||
7. **Add module versioning support** - Handle different module versions
|
||||
8. **Implement hot module replacement** - Live development workflow
|
||||
9. **Add module marketplace** - Plugin discovery and installation
|
||||
|
||||
---
|
||||
|
||||
## Conclusion
|
||||
|
||||
The current web application has excellent technical foundations, particularly the Nostr infrastructure (RelayHub/NostrclientHub), but requires significant architectural refactoring to achieve true modularity.
|
||||
|
||||
**Key Strengths to Preserve:**
|
||||
- Robust Nostr client implementation
|
||||
- Clean component organization
|
||||
- Solid TypeScript foundations
|
||||
- PWA capabilities
|
||||
|
||||
**Critical Areas for Improvement:**
|
||||
- Plugin architecture implementation
|
||||
- Module boundary enforcement
|
||||
- Event-driven communication
|
||||
- Development workflow optimization
|
||||
|
||||
**Estimated Effort:**
|
||||
- **Phase 1 (Core Infrastructure):** 2-3 weeks
|
||||
- **Phase 2 (Module Extraction):** 3-4 weeks
|
||||
- **Phase 3 (Advanced Features):** 2-3 weeks
|
||||
|
||||
The investment in modular architecture will enable independent development of features, easier testing, better code maintainability, and the ability to dynamically enable/disable functionality based on deployment requirements.

- **Composables Pattern**: Good reactive logic encapsulation (`useRelayHub`, `useNostrChat`, `useMarket`)
|
||||
- **UI Component Library**: Well-structured Shadcn/ui components with consistent design system
|
||||
|
||||
#### 2. Component Organization (7/10)
|
||||
- Components grouped by domain (`/market`, `/nostr`, `/events`, `/auth`)
|
||||
- Page-level routing with lazy loading implementation
|

### **Critical Issues (What's Missing)**
|
||||
|
||||
#### 1. No Plugin Architecture (3/10)
|
||||
- **Hard-coded routes**: All features baked into main router configuration
|
||||
- **Tight coupling**: Components directly import across modules without abstraction
|
||||
- **No feature isolation**: Cannot develop/deploy components independently
|

- **No plugin registration system**: Missing infrastructure for dynamic feature loading
|
||||
|
||||
#### 2. Cross-Module Dependencies (4/10)

// Payment monitor importing market types directly
|
||||
src/lib/services/paymentMonitor.ts: import type { Order } from '@/stores/market'
|
||||

src/components/layout/Navbar.vue: import { nostrChat } from '@/composables/useNostrChat'
|
||||
|
||||
// Services importing market store directly
|
||||
src/lib/services/nostrmarketService.ts: import type { Stall, Product, Order } from '@/stores/market'
|
||||
```
|
||||
|
||||
#### 3. Missing Module Boundaries (5/10)
|
||||
- No clear module interfaces/contracts
|

|
||||
|

|
||||
|
||||
## Required Changes for Modular Architecture
|
||||
|
||||
### Phase 1: Core Infrastructure Refactor
|
||||
|
||||
#### 1. Create Module System
|
||||
```typescript
|
||||
// /src/modules/base/types.ts
|
||||
interface ModuleConfig {
|
||||
name: string
|
||||
routes: RouteConfig[]
|
||||
components: ComponentConfig[]
|
||||
services: ServiceConfig[]
|
||||
dependencies?: string[]
|
||||
}
|
||||
|
||||
interface ModulePlugin {
|
||||
install(app: App, options?: any): void
|
||||
uninstall(): void
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. Plugin Registration System
|
||||
```typescript
|
||||
// /src/core/plugin-manager.ts
|
||||
class PluginManager {
|
||||
private plugins = new Map<string, ModulePlugin>()
|
||||
|
||||
register(module: ModulePlugin): void
|
||||
unregister(name: string): void
|
||||
getModule(name: string): ModulePlugin
|
||||
getDependencies(name: string): string[]
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 2: Module Extraction
|
||||
|
||||
#### 1. Base Module Structure
|
||||
```
|
||||
/src/modules/base/
|
||||
nostr/
|
||||
relayHub.ts # Centralized relay management
|
||||
nostrclientHub.ts # Client connection handling
|
||||
types.ts # Nostr-specific types
|
||||
auth/
|
||||
lnbits.ts # LNbits authentication
|
||||
composables/
|
||||
pwa/
|
||||
install-prompt.ts
|
||||
notifications.ts
|
||||
ui/ # Shadcn components
|
||||
```
|
||||
|
||||
#### 2. Feature Modules
|
||||
```
|
||||
/src/modules/
|
||||
nostr-feed/
|
||||
components/
|
||||
NostrFeed.vue
|
||||
composables/
|
||||
useFeed.ts
|
||||
services/
|
||||
feedService.ts
|
||||
index.ts # Module export

|
||||
index.ts
|
||||
chat/
|
||||
events/
|
||||
```
|
||||
|
||||
#### 3. Module Interface Standards
|
||||
```typescript
|
||||
// Each module exports standardized interface
|
||||
export interface NostrFeedModule extends ModulePlugin {
|
||||
name: 'nostr-feed'
|
||||
components: {
|
||||
NostrFeed: Component
|
||||
}
|
||||
routes: RouteConfig[]
|
||||
dependencies: ['base']
|
||||
config?: NostrFeedConfig
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 3: Event-Driven Communication
|
||||
|
||||
#### Replace Direct Imports with Event Bus
|
||||
```typescript
|
||||
// /src/core/event-bus.ts
|
||||
interface ModuleEventBus {
|
||||
emit(event: string, data: any): void
|
||||
on(event: string, handler: Function): void
|
||||
off(event: string, handler: Function): void
|
||||
}
|
||||
|
||||
// Example usage:
|
||||
// Market module: eventBus.emit('order:created', order)
|
||||
// Chat module: eventBus.on('order:created', handleNewOrder)
|
||||
```
|
||||
|
||||
#### Dependency Injection Container
|
||||
```typescript
|
||||
// /src/core/di-container.ts
|
||||
class DIContainer {
|
||||
provide<T>(token: string, instance: T): void
|
||||
inject<T>(token: string): T
|
||||
|
||||
// Module-scoped injection
|
||||
provideForModule(module: string, token: string, instance: any): void
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Recommended Ground-Up Architecture
|
||||
|
||||
If rebuilding from scratch, implement these architectural patterns:
|
||||
|
||||
### 1. Module-First Architecture
|
||||
```
|
||||
src/
|
||||
core/ # Base app infrastructure
|
||||
plugin-manager.ts # Plugin registration & lifecycle
|
||||
di-container.ts # Dependency injection
|
||||
event-bus.ts # Inter-module communication
|
||||
module-registry.ts # Module discovery & loading
|
||||
base-services/ # Core services
|
||||
modules/
|
||||
base/ # Core functionality (required)
|
||||
nostr/ # RelayHub, NostrclientHub
|
||||
auth/ # LNbits authentication
|
||||
pwa/ # Progressive Web App features
|
||||
ui/ # Shadcn component library
|
||||
nostr-feed/ # Announcements & social feed
|
||||
market/ # Marketplace functionality
|
||||
chat/ # Nostr chat implementation
|
||||
events/ # Event ticketing system
|
||||
app.ts # Application composition & startup
|
||||
```
|
||||
|
||||
### 2. Configuration-Driven Setup
|
||||
```typescript
|
||||
// /src/app.config.ts
|
||||
export const appConfig = {
|
||||
modules: {
|
||||
base: {
|
||||
required: true,
|
||||
nostr: {
|
||||
relays: process.env.VITE_NOSTR_RELAYS
|
||||
}
|
||||
},
|
||||
'nostr-feed': {
|
||||
enabled: true,
|
||||
config: {
|
||||
refreshInterval: 30000,
|
||||
maxPosts: 100
|
||||
}
|
||||
},
|
||||
market: {
|
||||
enabled: true,
|
||||
config: {
|
||||
defaultCurrency: 'sats',
|
||||
paymentTimeout: 300000
|
||||
}
|
||||
},
|
||||
chat: {
|
||||
enabled: false // Can be toggled via config
|
||||
},
|
||||
events: {
|
||||
enabled: true,
|
||||
config: {
|
||||
ticketValidationEndpoint: '/api/tickets/validate'
|
||||
}
|
||||
}
|
||||
},
|
||||
features: {
|
||||
pwa: true,
|
||||
pushNotifications: true,
|
||||
electronApp: true
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Dynamic Module Loading
|
||||
```typescript
|
||||
// /src/core/module-loader.ts
|
||||
class ModuleLoader {
|
||||
async loadModule(name: string): Promise<ModulePlugin> {
|
||||
const module = await import(`@/modules/${name}/index.ts`)
|
||||
await this.resolveDependencies(module.dependencies || [])
|
||||
return module.default
|
||||
}
|
||||
|
||||
async unloadModule(name: string): Promise<void> {
|
||||
const module = this.getModule(name)
|
||||
if (module) {
|
||||
await module.uninstall()
|
||||
this.cleanupRoutes(name)
|
||||
this.cleanupServices(name)
|
||||
}
|
||||
}
|
||||
|
||||
private async resolveDependencies(deps: string[]): Promise<void> {
|
||||
for (const dep of deps) {
|
||||
if (!this.isModuleLoaded(dep)) {
|
||||
await this.loadModule(dep)
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Module Development Workflow
|
||||
```bash
|
||||
# Develop single module in isolation
|
||||
npm run dev:module market
|
||||
|
||||
# Test module independently
|
||||
npm run test:module market
|
||||
|
||||
# Build specific modules only
|
||||
npm run build:modules market,chat
|
||||
|
||||
# Hot reload module during development
|
||||
npm run dev:hot-module nostr-feed
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Key Architectural Improvements
|
||||
|
||||
### 1. Dependency Inversion
|
||||
- Modules depend on interfaces, not concrete implementations
|
||||
- Services injected via DI container rather than direct imports
|
||||
- Clear separation between module contracts and implementations
|
||||
|
||||
### 2. Event-Driven Communication
|
||||
- Replace direct imports with event-based messaging
|
||||
- Loose coupling between modules via standardized events
|
||||
- Centralized event routing and handling
|
||||
|
||||
### 3. Module Lifecycle Management
|
||||
- Proper setup and teardown hooks for each module
|
||||
- Resource cleanup when modules are disabled/unloaded
|
||||
- Dependency resolution during module loading
|
||||
|
||||
### 4. Configuration Over Code
|
||||
- Enable/disable features via configuration files
|
||||
- Runtime module toggling without code changes
|
||||
- Environment-specific module configurations
|
||||
|
||||
### 5. Hot Module Replacement
|
||||
- Develop modules independently without full app restart
|
||||
- Live reloading of individual modules during development
|
||||
- Isolated testing environments for each module
|
||||
|
||||

|
||||
|
||||
## Implementation Roadmap
|
||||
|
||||
### High Priority (Immediate)
|
||||
1. **Extract RelayHub/NostrclientHub to base module** (mostly complete)
|
||||
2. **Create plugin registration system** - Core infrastructure for module loading
|
||||
3. **Convert nostr-feed to plugin pattern** - Proof of concept implementation
|
||||
|
||||
### Medium Priority (Phase 2)
|
||||
4. **Implement event bus communication** - Replace direct imports between modules
|
||||
5. **Add module lifecycle management** - Proper setup/teardown hooks
|
||||
6. **Create development tooling** - Scripts for isolated module development
|
||||
|
||||
### Low Priority (Phase 3)
|
||||
7. **Add module versioning support** - Handle different module versions
|
||||
8. **Implement hot module replacement** - Live development workflow
|
||||
9. **Add module marketplace** - Plugin discovery and installation
|
||||

|
||||
## Conclusion
|
||||
|
||||
The current web application has excellent technical foundations, particularly the Nostr infrastructure (RelayHub/NostrclientHub), but requires significant architectural refactoring to achieve true modularity.
|
||||
|
||||
**Key Strengths to Preserve:**
|
||||
- Robust Nostr client implementation
|
||||
- Clean component organization
|
||||
- Solid TypeScript foundations
|
||||
- PWA capabilities
|
||||
|
||||
**Critical Areas for Improvement:**
|
||||
- Plugin architecture implementation
|
||||
- Module boundary enforcement
|
||||
- Event-driven communication
|
||||
- Development workflow optimization
|
||||
|
||||
**Estimated Effort:**
|
||||
- **Phase 1 (Core Infrastructure):** 2-3 weeks
|
||||
- **Phase 2 (Module Extraction):** 3-4 weeks
|
||||
- **Phase 3 (Advanced Features):** 2-3 weeks
|
||||
|
||||
The investment in modular architecture will enable independent development of features, easier testing, better code maintainability, and the ability to dynamically enable/disable functionality based on deployment requirements.
