webpack ProfilingPlugin

Generate Chrome profile file which includes timings of plugins execution. Outputs events.json file by default. It is possible to provide custom file path using outputPath option.

Options

• outputPath: A relative path to a custom output file (json)

Usage: default

new webpack.debug.ProfilingPlugin()

Usage: custom outputPath

new webpack.debug.ProfilingPlugin({
  outputPath: "profiling/profileEvents.json"
})

In order to view the profile file:

• Run webpack with ProfilingPlugin.
• Go to Chrome, open the Profile Tab.
• Drag and drop generated file (events.json by default) into the profiler.

It will then display timeline stats and calls per plugin!
