webpack-bundle-analyser

library1.4.0jsnpmunverified

Webpack Bundle Analyser is a tool for analysing Webpack bundle output, forked from the official Webpack analyse website. Version 1.4.0 is the latest stable release, but the project appears to be in early development with an incomplete todo list including open browser after compiling, better error handling, and graph viewing improvements. It allows local or CI-based bundle analysis by generating a stats file and producing a static HTML report. Differentiators from alternatives like webpack-bundle-analyzer include a different UI and the ability to run without a plugin by using webpack --profile --json. However, it lacks the interactive treemap visualization and active maintenance of its alternative.

webpack-bundle-analyser (CLI)

✓ npx webpack-bundle-analyser build -o dist -d data.json

✗ webpack-bundle-analyser (without arguments)

The package provides a CLI only; there is no programmatic JS API. The command must include build, output directory, and stats file flag.

Demonstrates how to generate a webpack stats file and use the CLI to produce an analyser report.

// 1. Generate webpack stats file webpack --profile --json > data.json // 2. Run the analyser npx webpack-bundle-analyser build -o dist -d data.json // 3. Serve the output (e.g., with npx serve) npx serve dist

webpack-bundle-analyser --version
