PERF202: Large frontend bundle or heavy import

Severity: medium · Category: frontend · Applies to: nextjs, react

Why it matters

Large bundles slow the first page load, especially on mobile networks.

How to fix

Split the bundle with dynamic imports and replace heavy libraries (moment, whole lodash) with smaller ones (date-fns, lodash-es / per-method imports).

Ignoring this rule

Skip it everywhere in devshield.yml:

ignore:
  - PERF202

Or skip one line with a comment on that line or the line above:

devshield-ignore: PERF202
