@nessframework/analyzer

Generates machine-readable JSON and human-readable HTML bundle reports. A size budget can fail builds that grow beyond an expected limit.

ness add analyzer --dev

ness.config.mjs

import analyzer from '@nessframework/analyzer';
import { defineNessConfig } from '@nessframework/router';
import { ness } from '@nessframework/router/vite';

export default defineNessConfig({
  vite: {
    plugins: [ness({ plugins: [analyzer({ maxSize: 750_000 })] })],
  },
});

Production builds emit ness-bundle-report.json and ness-bundle-report.html. Set html: false to emit only the JSON, and reportFile or htmlFile to name them something else.

maxSize is compared against the total size of one build output. A Ness build runs Vite more than once — for the client and for the server — and each run writes its own report and is checked against the budget separately.
