Use when build times are slow. Use when optimizing TypeScript projects. Use when configuring project references. Use when dealing with large codebases. Use when improving IDE responsiveness.

Overview

# Pay Attention to Compiler Performance

Overview

TypeScript compilation can become slow in large projects. Monitor and optimize compiler performance using techniques like project references, proper tsconfig settings, and avoiding expensive type patterns. Fast compilation improves developer experience.

When to Use This Skill

Build times are slow
Optimizing TypeScript projects
Configuring project references
Working with large codebases
Improving IDE responsiveness

The Iron Rule

Monitor and optimize TypeScript performance. Use project references, avoid expensive type patterns, and keep compilation fast.

Performance Tips

```typescript

// AVOID: Expensive recursive types

type DeepPartial = T extends object

? { [K in keyof T]?: DeepPartial }

: T;

// PREFER: Iterative approaches, project references

// Split large projects using project references

```

```json

// tsconfig.json optimizations

{

"compilerOptions": {

"incremental": true, // Incremental compilation

"tsBuildInfoFile": ".tsbuildinfo"

}

```
