Express.js applications can connect with business platforms and third-party services.

We integrate:

  • Payment gateways
  • CRM and ERP platforms
  • Email providers
  • SMS and WhatsApp services
  • Cloud storage
  • Maps and location services
  • Analytics tools
  • Authentication providers

Each integration includes validation, error handling, logging and secure credential management.

Express.js SaaS Development

Express.js can support SaaS products with multiple users, subscription plans and business modules.

A custom SaaS backend may include:

  • Feature permissions
  • Usage tracking
  • Reports and analytics
  • Notifications
  • Activity logs

Our team plans the backend so new features and customer accounts can be added efficiently.

Express.js Migration and Modernization

Businesses using unstructured or outdated Node.js backends can modernize them with a cleaner Express.js architecture.

Migration services may include:

  • Existing backend assessment
  • Route restructuring
  • Controller and service separation
  • TypeScript migration
  • Database query optimization
  • Authentication improvements
  • Validation setup
  • Error-handling improvements
  • Dependency updates
  • Docker deployment

Migration can be completed module by module to reduce operational disruption.

Express.js Security and Performance

Backend security and performance are considered throughout development.

Our Express.js practices may include:

  • Input validation
  • Role-based authorization
  • Secure password hashing
  • Token protection
  • Rate limiting
  • Security headers
  • File upload restrictions
  • Environment variable protection
