Incremental compilation caches build information in .tsbuildinfo files to speed up subsequent tsc builds.
1. Introduction & Architecture
2. Deep Dive & Core Concepts
When enabled, TypeScript re-checks only files that changed since the last build saved in the cache.
3. Basic Code Example
4. Advanced Production Patterns
5. Interactive Code Playground
console.log("Incremental builds reuse compile cache files.");6. Common Pitfalls & Edge Cases
Note: Add
.tsbuildinfo files to your .gitignore file.7. Interview Q&A & Quizzes
Q: What does 'incremental: true' do?
A: Saves compilation state to a .tsbuildinfo cache file, allowing tsc to skip re-checking unchanged files.
