#performance.profile

• Type: boolean
• Default: false

Whether to capture timing information for each module, the same as the profile config of Rspack.

When enabled:

• Rsbuild will automatically generate a dist/stats.json file through bundle analyzer.
• Rspack will include build-time information when generating stats.json or other statistics files.

#Example

export default {
  performance: {
    profile: true,
  },
};

When enabled, Rspack generates a JSON file with statistics about modules, including timing information for each module.
