sourcemapIgnoreList

• Type: optional sourcemapIgnoreList: boolean | StringOrRegExp | SourcemapIgnoreListOption

Defined in: options/output-options.ts:150

Control which source files are included in the sourcemap ignore list. Files in the ignore list are excluded from debugger stepping and error stack traces.

• false: Include all source files in the ignore list
• true: Include no source files in the ignore list
• string: Files containing this string in their path will be included in the ignore list
• RegExp: Files matching this regular expression will be included in the ignore list
• function: Custom function (source: string, sourcemapPath: string) => boolean to determine if a source should be ignored

Performance

Using static values (boolean, string, or RegExp) is significantly more performant than functions. Calling JavaScript functions from Rust has extremely high overhead, so prefer static patterns when possible.
