Bugfixes

• Source Code is splitted into lines via custom code instead of using a RegExp
  • In weird edge cases the RegExp caused a Stack Overflow

Bugfixes

• RawSources with Buffers can now be concatenated with ConcatSource
• Source Code is splitted into lines via custom code instead of using a RegExp
  • In weird edge cases the RegExp caused a Stack Overflow

Bugfix

• improve handling of null sources and sourceContents

Performance

• faster streaming when only lines are mapped

equal to 3.1.0

Bugfix

• improve handling of invalid mappings (like zero sized or negative)

Performance

• add SourceMapSource.buffer for better performance
• more efficient serialization of source mappings

Bugfix

• avoid crashing when trying to compare the name with the original source, but there is no sourcesContent in SourceMap

Bugfix

• fix invalid mappings when multiple lines with multiple chunks are replaced

Bugfix

• restore backward-compat format for storing end position of replacements

Bugfix

• fix incorrect offset sign when doing replacements

Bugfixes

• fix ConcatSource off-by-1 bug

Performance

• remove all dependencies
• refactoring for performance
  • remove node() and listMap()
  • add streamChunks()

Performance

• fix type bug in CachedSource which lead to bad hashing performance

Performance

• add caching to node and listMap

Performance

• add caching to updateHash

Performance

• fix a performance bug when processing minimized files with SourceMaps

Bugfixes

• Some Sources use to return an empty SourceMap instead of null as map
  • They correctly return null instead now

Bugfixes

• fix crash with source "." is not in SourceMap

API

Additions

• add buffer method to Source
• add SizeOnlySource
• expose everything needed for serialization as public methods
• add CompatSource
• add support for a lazy function as original Source for CachedSource

Removals

• remove node and listNode methods from public API
• remove LineToLineMappedSource

Bugfixes

• ConcatSource falls back to sourceAndMap when node() or listMap() is not available
• PrefixSource do no longer insert prefix in the middle of the line in some cases
• fix updateHash for SourceMapSource
• fix crash when Source in CachedSource returns null map

Performance:

• avoid unnecessary sorting in ReplaceSource
• make exports lazy
• cache utf-8 conversion
• allow keeping Buffer instead of string and only convert it lazily
• add optimization step to ConcatSource which converts strings to RawSources (which cache)
• cache Buffers instead of string in CachedSource cache for map()

Changes

• increase minimum node.js version to 10.13

Other

• add Source types to hash

Features

• add support for a lazy function as original Source for CachedSource

Bugfixes
