Why TypeScript for SaaS?

TypeScript Strengths

  • Catches errors at compile time instead of runtime
  • Excellent IDE support with autocomplete and refactoring
  • Self-documenting code through types
  • Easier onboarding for new team members

SaaS Requirements

  • Scaling infrastructure to handle rapid user growth
  • Multi-tenant architecture and data isolation
  • API design and third-party integrations
  • SOC 2 Type II compliance for enterprise customers

TypeScript Use Cases in SaaS

Architecture Patterns for SaaS

Standard TypeScript architecture patterns

Pattern 2

Best practices for SaaS implementations

Pattern 3

Scalable design for SaaS workloads

Performance

TypeScript compiles to JavaScript with no runtime overhead. Use incremental compilation, project references, and proper tsconfig for faster builds.

Security

Type safety helps prevent runtime errors but doesn't replace runtime validation. Use Zod or similar for runtime type checking at system boundaries.

Scaling

TypeScript becomes more valuable as codebases grow. Consider project references for large monorepos to optimize build times.

SaaS Compliance with TypeScript

Required Compliance

SOC 2 Type II

Implementation Considerations

  • Data minimization and purpose limitation
