Module incremental 

Incremental Compilation Support

This module implements TypeScript’s incremental compilation feature, which enables:

• Faster rebuilds by caching compilation results
• .tsbuildinfo file persistence for cross-session caching
• Smart dependency tracking for minimal recompilation

Build Info Format

The .tsbuildinfo file stores:

• Version information for cache invalidation
• File hashes for change detection
• Dependency graphs between files
• Emitted file signatures for output caching

Structs

BuildInfo

Build information persisted between compilations

BuildInfoBuilder

Builder for creating build info incrementally

BuildInfoOptions

Compiler options that affect build caching

CachedDiagnostic

Cached diagnostic information for incremental builds

CachedRelatedInformation

Cached related information for diagnostics

ChangeTracker

Tracks changes between builds

EmitSignature

Emit output signature for caching

FileInfo

Information about a single compiled file

Constants

BUILD_INFO_VERSION

Version of the build info format

Functions

compute_export_signature

Compute a signature for a file’s exports (for dependency tracking)

compute_file_version

Compute a version string for a file (content hash)

default_build_info_path

Determine the default .tsbuildinfo path based on configuration
