bundle-analyzer

To analyze Next.js bundle size, you can run a script that inspects your application's build output to surface oversized chunks and pinpoint specific modules causing bloat. This process identifies bottlenecks without requiring external tools beyond npm build.

Identifying code-splitting opportunities involves generating a bundle-size report from your Next.js build to highlight large modules. Once oversized chunks are surfaced, you can pinpoint specific optimization opportunities to implement lazy loading.

Yes, you can optimize Next.js initial load performance by analyzing your build outputs to find large bundles. Surfacing these oversized chunks provides actionable recommendations to reduce load times through targeted code-splitting.

No, you do not need external build tools to analyze your Next.js bundle size. The process relies solely on an included script and your standard npm build to generate the bundle-size report and identify bottlenecks.

You should run a bundle-size analysis when your Next.js app has large chunks that degrade initial load performance. It helps surface large modules and suggests code-splitting or lazy loading to resolve size bottlenecks.
