Core Concepts Overview

Architecture

Your product is built on three core pillars:

Loading diagram...

Components

Client Application

The user-facing interface that interacts with your API. Can be web, mobile, or desktop.

API Gateway

Routes requests to appropriate services and handles authentication, rate limiting, and caching.

Business Logic

Core application logic that processes requests and orchestrates operations.

Data Layer

Manages data persistence, validation, and retrieval.

Key Principles

1. Simplicity First

We prioritize simple, intuitive APIs over complex abstractions.

typescript

// Good: Simple and clear
await client.send("Hello");

// Avoid: Overly complex
await client.createConnection().then((conn) => conn.getChannel().send("Hello"));

2. Type Safety

Leverage TypeScript for compile-time safety:

typescript

interface User {
    id: string;
    name: string;
    email: string;
}

function getUser(id: string): Promise<User> {
    return api.users.get(id);
}

3. Error Handling

Always handle errors gracefully:

typescript

try {
    const user = await getUser("123");
} catch (error) {
    if (error instanceof NotFoundError) {
        // Handle missing user
    } else if (error instanceof AuthError) {
        // Handle authentication error
    } else {
        // Handle unexpected error
    }
}

Data Flow

Understanding how data flows through your application:

All API requests are authenticated, validated, and logged automatically.

Request Validation - Incoming requests are validated against schemas
Authentication - User identity is verified using JWT tokens
Authorization - Permissions are checked for the requested resource
Processing - Business logic executes the operation
Response - Formatted response is returned to the client

Best Practices

Use TypeScript

Leverage type safety for fewer runtime errors

Handle Errors

Always implement proper error handling

Cache Responses

Cache frequently accessed data

Monitor Performance

Track metrics and optimize bottlenecks
