Dynamo-NTS

!Dynamo-NTS Logo

Dynamo-NTS (NodeTS) is a comprehensive backend framework for building robust, secure, and scalable Node.js applications with TypeScript. Built on top of Dynamo FSM (@futdevpro/fsm-dynamo), it provides a structured approach to server-side development with clear separation of concerns, extensive configuration options, and production-ready implementations for common backend tasks.

Dynamo-NTS uses Dynamo FSM as its foundational layer, implementing the server-side components of the FSM architecture. All core interfaces, types, and utilities are provided by FSM, ensuring consistency and type safety across the entire Dynamo ecosystem.

Dynamo-NTS is part of the unified Dynamo ecosystem, a full-stack development framework designed to accelerate the development of scalable web applications. The ecosystem consists of interconnected packages that work together seamlessly, with Dynamo-NTS serving as the backend implementation layer. The frontend counterpart is Dynamo NGX, which uses Dynamo NGX Models for type-safe model definitions.

Dynamo-NTS is built with two key principles:

- Full Override Capability: Every component, service, and class can be overridden or extended. The framework provides a solid foundation with sensible defaults, but you have complete control to customize or replace any part to fit your specific needs. This makes Dynamo-NTS highly customizable and adaptable to any project requirements.

- Complete Type Information: All types, interfaces, and definitions are included in the compiled output. This ensures excellent readability and maintainability—everything you need is available at compile time through TypeScript's type system, providing full IntelliSense support and eliminating the need to reference external documentation during development.

Dynamo-NTS simplifies complex system definitions by abstracting common backend infrastructure into simple parameterization. Instead of manually configuring various libraries and services, you define your application through straightforward parameter objects:

- Express Usage: HTTP/HTTPS server setup, routing, middleware, and error handling are configured through DyNTS_App_Params, DyNTS_Http_Settings, and DyNTS_RoutingModule parameters (simplifies Express server initialization and route management)
- MongoDB/Mongoose Usage: Database connections, models, schemas, and operations are managed through DyNTS_DBService and DyNTS_DataService with simple data model parameter definitions (simplifies Mongoose schema creation and model management)
- Socket.io Usage: Real-time communication setup, event handling, and presence tracking are configured through DyNTS_SocketServerService parameters and the DyNTS_AppExtended class (simplifies Socket.io server initialization and event management)
- Nodemailer Usage: Email sending with templating, attachments, and async delivery is handled through DyNTS_EmailService with template component definitions (simplifies Nodemailer transporter setup and email template management)
- OAuth2 Implementation: Complete OAuth2.0 protocol flows including authorization codes, token exchange, and refresh tokens are managed through DyNTS_OAuth2_Controller and DyNTS_OAuth2_AuthService (simplifies complex OAuth2 flow implementation)
- Axios Usage: HTTP client requests to external APIs are standardized through DyNTS_ApiService with DyNTS_ApiCall_Params configuration (simplifies Axios request setup, error handling, and response management)
- Discord.js / Slack / Teams Bot Development: Platform-agnostic bot framework through DyNTS_Bot_MessagingProvider_ServiceBase and bot modules (simplifies Discord.js, Slack, and Teams bot development with unified interfaces)
- OpenAI / AI Provider Integration: AI/LLM operations including chat, embeddings, and vector search are abstracted through DyNTS_AI_Provider_ServiceBase and provider implementations (simplifies OpenAI SDK usage and enables multi-provider architecture)
- Location Tracking: IP-based geolocation through geoip-lite is integrated into the usage tracking module (simplifies location data collection from HTTP requests)

This parameterization approach eliminates boilerplate code and provides a consistent, type-safe interface for all backend operations. Instead of learning multiple library APIs and their configuration patterns, developers work with unified Dynamo-NTS parameter objects that handle the underlying complexity.

Quick Start

The following example demonstrates how to set up a basic Dynamo-NTS application with routing and socket support:

`typescript
import {
DyNTS_AppExtended,
DyNTS_App_Params,
DyNTS_GlobalService_Settings,
DyNTS_Http_Settings,
DyNTS_RoutingModule
} from '@futdevpro/nts-dynamo';
import {
DyNTS_SocketServerService
} from '@futdevpro/nts-dynamo/socket';
import { DyFM_usageSession_dataParams } from '@futdevpro/fsm-dynamo/usage';
import { DyFM_customData_dataParams } from '@futdevpro/fsm-dynamo/custom-data';
import { DyNTS_getUsageRoutingModule } from '@futdevpro/nts-dynamo/usage';
import { DyNTS_getTestRoutingModule } from '@futdevpro/nts-dynamo/test';

import { AuthService } from './core-services/auth.service';
import { Email_ServiceCollection } from './core-services/email.service-collection';
import { User_Controller } from './routes/user/user.controller';
import { Chat_SocketServerService } from './socket-services/chat.socket-server-service';

export class App extends DyNTS_AppExtended {

getAppParams(): DyNTS_App_Params {
return new DyNTS_App_Params({
name: 'My Application',
version: '1.0.0',
dbName: 'myapp',
dbUri: process.env.MONGO_URL || 'mongodb://localhost:27017/myapp',
systemShortCodeName: 'MYAPP',
});
}

getGlobalServiceCollection(): DyNTS_GlobalService_Settings {
return {
authService: AuthService.getInstance(),
emailServiceCollection: Email_ServiceCollection.getInstance(),
dbModels: [
// Your data model parameters here
DyFM_usageSession_dataParams,
DyFM_customData_dataParams,
],
};
}

getPortSettings(): DyNTS_Http_Settings {
return new DyNTS_Http_Settings({
httpPort: 3000,
});
}

getRoutingModules(): DyNTS_RoutingModule[] {
return [
new DyNTS_RoutingModule({
route: '/user',
controllers: [
User_Controller.getInstance(),
],
}),
DyNTS_getTestRoutingModule(),
DyNTS_getUsageRoutingModule(),
];
}

getSocketServices(): DyNTS_SocketServerService[] {
return [
Chat_SocketServerService.getInstance(),
];
}
}

// Start the application
const app = new App();
`

Core Concepts

Dynamo-NTS uses Dynamo FSM as its foundation, implementing all server-side components defined in the FSM architecture. All types, interfaces, and base models are provided by FSM, ensuring full type safety and consistency.

$3

Dynamo-NTS is designed with extensibility in mind. Every component, service, and class can be overridden or extended to meet your specific requirements:

- Service Override: All services (authentication, email, data services, etc.) can be extended or completely replaced with custom implementations
- Method Override: Abstract methods in base classes allow you to customize behavior while maintaining the framework structure
- Configuration Override: Global settings, route security, and application parameters can be overridden at any level
- Type Safety: All overrides maintain full TypeScript type safety, with all types and interfaces available at compile time

This design philosophy ensures that Dynamo-NTS provides a solid foundation while remaining fully customizable for your specific use cases.

$3

All types, interfaces, and definitions are included in the compiled output, ensuring excellent readability and maintainability. When you compile your project, you have access to:

- Complete type definitions for all services, models, and interfaces
- Full IntelliSense support in your IDE
- Compile-time type checking for all framework components
- Self-documenting code through TypeScript's type system

This approach eliminates the need to reference external documentation during development—everything you need is available in your IDE's autocomplete and type hints.

$3

Dynamo-NTS provides two main application base classes that simplify Express server setup:

- DyNTS_App: Basic application class for standard HTTP server applications without real-time socket support
- DyNTS_AppExtended: Extended application class that includes built-in socket server capabilities for real-time communication (simplifies Socket.io setup)

Both classes abstract away Express server configuration, requiring you to implement several abstract methods with simple parameter objects:

- getAppParams(): Define application parameters (name, version, database name, etc.) - replaces Express app initialization
- getGlobalServiceCollection(): Configure global services (authentication, email, database models) - replaces manual service registration
- getPortSettings(): Configure HTTP/HTTPS ports - replaces Express server.listen() configuration
- getRoutingModules(): Define API routes and controllers - replaces Express router setup

$3

Data services provide a structured way to interact with MongoDB, simplifying Mongoose model and schema definitions:

- DyNTS_DBService: Low-level MongoDB service for direct database operations (simplifies Mongoose model creation)
- DyNTS_DataService: High-level data service with business logic, validation, and dependency management (simplifies MongoDB CRUD operations)
- DyNTS_ArchiveDataService: Service for managing archived data in separate collections

Instead of manually creating Mongoose schemas and models, you define data models through DyFM_DataModel_Params (from FSM), and Dynamo-NTS handles schema generation, model creation, and connection management automatically. Data services handle CRUD operations, data validation, dependency tracking, and provide methods for searching, filtering, and managing data relationships.

$3

The routing system provides a structured approach to defining RESTful API endpoints, simplifying Express router configuration:

- DyNTS_RoutingModule: Groups related controllers under a common route path (replaces Express Router setup)
- DyNTS_Controller: Abstract base class for defining HTTP endpoints (simplifies Express route handlers)
- DyNTS_Endpoint_Params: Configuration for individual API endpoints (replaces Express route definitions)

Instead of manually setting up Express routers and route handlers, you define endpoints through parameter objects. Controllers define endpoints with support for:
- Multiple HTTP methods (GET, POST, PUT, PATCH, DELETE)
- Pre-processing middleware (authentication, validation)
- Task functions for handling requests
- Route security levels (open, secure, both)

$3

The DyNTS_GlobalService provides centralized access to:

- Authentication service
- Email service collection
- Database models registry
- Error handlers
- Socket server instances

$3

Dynamo-NTS provides an abstract DyNTS_AuthService class that you can extend to implement your authentication logic. The framework supports:

- Token-based authentication
- OAuth2 flows (via the OAuth2 module)
- Session management
- Route-level security configuration

This example shows a complete application setup using DyNTS_AppExtended:

`typescript
import {
DyNTS_AppExtended,
DyNTS_App_Params,
DyNTS_GlobalService_Settings,
DyNTS_Http_Settings,
DyNTS_RoutingModule
} from '@futdevpro/nts-dynamo';
import { DyNTS_SocketServerService } from '@futdevpro/nts-dynamo/socket';

export class App extends DyNTS_AppExtended {

getAppParams(): DyNTS_App_Params {
return new DyNTS_App_Params({
name: 'My Server',
version: '1.0.0',
dbName: 'myapp',
});
}

getGlobalServiceCollection(): DyNTS_GlobalService_Settings {
return {
authService: AuthService.getInstance(),
dbModels: [
// Your data models
],
};
}

getPortSettings(): DyNTS_Http_Settings {
return new DyNTS_Http_Settings({
httpPort: 3000,
});
}

getRoutingModules(): DyNTS_RoutingModule[] {
return [
new DyNTS_RoutingModule({
route: '/api',
controllers: [
MyController.getInstance(),
],
}),
];
}

getSocketServices(): DyNTS_SocketServerService[] {
return [
MySocketService.getInstance(),
];
}
}
`

$3

Multiple routing modules can be configured to organize your API:

`typescript
getRoutingModules(): DyNTS_RoutingModule[] {
return [
new DyNTS_RoutingModule({
route: '/user',
controllers: [
User_Controller.getInstance(),
UserData_Controller.getInstance(),
UserSettings_Controller.getInstance(),
],
}),
new DyNTS_RoutingModule({
route: '/project',
controllers: [
Project_Controller.getInstance(),
ProjectExtension_Controller.getInstance(),
],
}),
new DyNTS_RoutingModule({
route: '/server',
controllers: [
ServerStatus_Controller.getInstance(),
],
}),
DyNTS_getTestRoutingModule(),
DyNTS_getUsageRoutingModule(),
];
}
`

$3

Controllers define API endpoints with authentication and business logic:

`typescript
import { Request, Response } from 'express';
import { DyNTS_Controller, DyNTS_Endpoint_Params } from '@futdevpro/nts-dynamo';
import { DyFM_HttpCallType } from '@futdevpro/fsm-dynamo';

export class User_Controller extends DyNTS_Controller {

static getInstance(): User_Controller {
return User_Controller.getSingletonInstance();
}

private authService: AuthService = AuthService.getInstance();

setupEndpoints(): void {
this.endpoints = [
new DyNTS_Endpoint_Params({
name: 'getUser',
type: DyFM_HttpCallType.get,
endpoint: '/get/:userId',
preProcesses: [this.authService.authenticate_tokenSelf],
tasks: [
async (req: Request, res: Response, issuer: string): Promise => {
const userService = new User_DataService({ issuer });
await userService.getDataById(req.params.userId);
res.send(userService.data);
},
],
}),
new DyNTS_Endpoint_Params({
name: 'updateUser',
type: DyFM_HttpCallType.post,
endpoint: '/update',
preProcesses: [this.authService.authenticate_tokenSelf],
tasks: [
async (req: Request, res: Response, issuer: string): Promise => {
const userService = new User_DataService({ issuer });
await userService.saveData(req.body);
res.send(userService.data);
},
],
}),
];
}
}
`

$3

Data services provide a structured way to interact with MongoDB:

`typescript
import { DyNTS_DataService } from '@futdevpro/nts-dynamo';
import { DyFM_DataModel_Params } from '@futdevpro/fsm-dynamo'; // FSM provides the data model parameter definition

// Define your data model parameters
const userDataParams: DyFM_DataModel_Params = new DyFM_DataModel_Params({
dataName: 'userData',
typeSample: {
userId: '',
preferences: {},
},
// ... additional configuration
});

export class User_DataService extends DyNTS_DataService {
constructor(params: { issuer: string }) {
super(userDataParams);
this.issuer = params.issuer;
}

// Custom business logic methods
async getUserPreferences(userId: string): Promise {
await this.getDataByDependencyId({ userId });
return this.data?.preferences || {};
}
}
`

$3

Socket services enable real-time communication:

`typescript
import { DyNTS_SocketServerService, DyNTS_SocketPresence } from '@futdevpro/nts-dynamo/socket';

export class Chat_SocketServerService extends DyNTS_SocketServerService {

static getInstance(): Chat_SocketServerService {
return Chat_SocketServerService.getSingletonInstance();
}

protected setupSocketEvents(): void {
this.socketServer.on('connection', (socket) => {
socket.on('joinRoom', (roomId: string) => {
socket.join(roomId);
});

socket.on('sendMessage', async (data: { roomId: string; message: string }) => {
this.socketServer.to(data.roomId).emit('newMessage', data);
});
});
}
}
`

$3

Dynamo-NTS provides built-in support for MongoDB Atlas vector search with automatic vectorization:

`typescript
import { DyNTS_OAI_VectorDataService } from '@futdevpro/nts-dynamo/ai/open-ai';

export class Knowledge_DataService extends DyNTS_OAI_VectorDataService {

constructor() {
super(knowledgeDataParams);
}

async searchSimilarContent(query: string, limit: number = 10): Promise {
return await this.vectorSearch({
input: query,
searchInKey: 'content', // Property that has vectorization enabled
limit: limit,
numberOfCandidates: 100,
});
}
}
`

The vector search automatically:
- Creates embeddings for search queries using the configured AI provider
- Performs semantic search in MongoDB Atlas vector database
- Returns results sorted by relevance
- Supports filtering with additional MongoDB queries

Ecosystem Integration

Dynamo-NTS is part of the unified Dynamo ecosystem, which consists of several interconnected packages:

$3

The foundational package @futdevpro/fsm-dynamo that provides:
- Core interfaces and types shared across the ecosystem
- Base model definitions (used by all Dynamo-NTS data services)
- Utility functions
- Type definitions for system-wide use
- Data model parameter definitions (DyFM_DataModel_Params)

Dynamo-NTS is built on top of Dynamo FSM and implements the server-side components of the FSM architecture. All data models, interfaces, and type definitions used in Dynamo-NTS are provided by FSM, ensuring consistency and type safety across the entire ecosystem.

$3

The frontend counterpart @futdevpro/dynamo-ngx provides:
- Angular components and services
- Frontend models that integrate with Dynamo-NTS backend (using shared FSM types)
- Real-time communication clients (connects to Dynamo-NTS socket services)
- Form management and data table components

$3

The Dynamo ecosystem enforces consistent patterns across all packages:

- Naming Conventions: Consistent prefixes (DyNTS_ for backend, DyNX_ for frontend, DyFM_` for shared)
- Type Safety: Full TypeScript support with shared type definitions
- Architecture Patterns: Consistent service patterns, data models, and API structures
- Error Handling: Unified error handling across the stack
- Logging: Consistent logging patterns and utilities

This unified approach ensures that:
- Developers learn one set of patterns that apply everywhere
- Frontend and backend code integrate seamlessly
- Type safety is maintained across the entire stack
- Maintenance and updates are simplified
