In case the webpack docs ever lose this, here is a list of available devtools. Choose a developer tool to enhance debugging.
eval - Each module is executed with eval and //@ sourceURL.
source-map - A SourceMap is emitted. See also output.sourceMapFilename.
hidden-source-map - Same as source-map, but doesn't add a reference comment to the bundle.
inline-source-map - A SourceMap is added as DataUrl to the JavaScript file.
eval-source-map - Each module is executed with eval and a SourceMap is added as DataUrl to the eval.
cheap-source-map - A SourceMap without column-mappings. SourceMaps from loaders are not used.
cheap-module-source-map - A SourceMap without column-mappings. SourceMaps from loaders are simplified to a single mapping per line.
Prefixing @, # or #@ will enforce a pragma style. (Defaults to #, recommended)
Combinations are possible. hidden, inline, eval and pragma style are exclusive.
i. e. cheap-module-inline-source-map, cheap-eval-source-map, #@source-map
