Loading

Uses native performance.mark and performance.measure

Then outputs a log during build using a PerformanceObserver

These marks and measures should appear in the Chrome performance tab (but during the webpack build, are logged if enabled).

Performance logging in the webpack loaders can be enabled in the Next.js plugin:

withDocsInfra({
  performance: {
    logging: true,
    notableMs: 100,

    // measures that contain other measures are hidden by default,
    // because they can be misleading
    showWrapperMeasures: false,
})
