Question 1

How do I optimize Next.js bundle size on Vercel?

Accepted Answer

Install bundle-cop-vercel-plugin, point Next.js adapterPath at the adapter, and deploy. Bundle Cop analyzes build output on Vercel, attributes large modules to the importing file, and can fail the build when budgets are exceeded.

Question 2

What causes Next.js bundles to grow on Vercel?

Accepted Answer

Heavy dependencies such as moment, lodash, or chart libraries often land through a single import. Without attribution, teams only notice after slower LCP or higher bandwidth. Bundle Cop shows the culprit file on every deploy.

Question 3

Is Bundle Cop a webpack-bundle-analyzer alternative for Vercel?

Accepted Answer

Yes for shipping workflows. Instead of a local analyzer UI only, Bundle Cop runs in the Next.js build, writes bundle-report.json, diffs against production, and can post Vercel Checks so regressions are caught in CI.

Question 4

Can I enforce a Next.js bundle budget on deploy?

Accepted Answer

Yes. Add bundle-cop.config.json with path budgets and set enforce to warn or error. Error fails the build when the client bundle exceeds your limit.
