rsnext/packages/next-bundle-analyzer

Next.js + Webpack Bundle Analyzer

Use webpack-bundle-analyzer in your Next.js project

Installation

npm install --save @next/bundle-analyzer

or

yarn add @next/bundle-analyzer

Usage with environment variables

Create a next.config.js (and make sure you have next-bundle-analyzer set up)

const withBundleAnalyzer = require("@next/bundle-analyzer")({ enabled: process.env.ANALYZE === "true" });
module.exports = withBundleAnalyzer({});

Then you can run the command below:

# Analyze is done on build when env var is set
ANALYZE=true yarn build

When enabled two HTML files (client.html and server.html) will be outputted to <distDir>/analyze/. One will be for the server bundle, one for the browser bundle.
