Best Practices

Architectural patterns, optimization strategies, and security guidelines for Eseniiiav projects.

Architecture Design

Modular Structure

Design systems using modular patterns to separate concerns and improve scalability. 

// Example: Modular service pattern
class AuthService {
    constructor() {
        this.db = new Database();
    }
    verifyToken(token) { ... }
}

API Design

Use REST/GraphQL with clear endpoints, versioning, and consistent responses. 

// RESTful endpoint example
GET /api/v1/users/123
200 OK
{
  id: "123",
  name: "John Doe"
}

Database

Normalize schemas and partition data across read/write workloads for performance. 

// Example: Sharded collection
DB.users.find( { shardKey: "example" } );

CI/CD

Implement automated testing pipelines with canary deployments. 

Pipeline: dev → staging → production

Performance Tips

Caching

Implement Redis or in-memory caching for fast lookup of frequent data.

Load Balancing

Distribute traffic efficiently using round-robin or weighted algorithms.

Indexing

Optimize database reads by creating indexes on high-traffic query fields.

Security Best Practices

Authentication

  • Use OAuth2 or JSON Web Tokens (JWT)
  • Implement rate-limiting for login attempts
  • Store secrets in a vault (never in code or configuration)

Encryption

  • TLS for all communication channels
  • Encrypt sensitive data at rest (AES-256 or stronger)
  • Use FIPS 140-2 certified modules

Auditing

  • Enable audit logging for access and operations
  • Conduct regular penetration tests
  • Use WAFs to filter malicious traffic

Maintainable Code

Linter Usage

Configure linters like ESLint to ensure code consistency across teams. 

// .eslintrc example
{
  "rules": {
    "semi": [2, "always"]
  }
}

Type Safety

Use TypeScript or static typing to prevent runtime errors. 

function calculateTotal(input: Array): number {
    // ...
}

Code Reviews

Maintain peer review workflows with pull request automation.
