#No Bundles Parsed#

[Romicodes]

Issue description

... @valscion Getting the following error message when trying to create a npm run build

No bundles were parsed. Analyzer will show only original module sizes from stats file.

Webpack Bundle Analyzer is started at http://127.0.0.1:8888
Use Ctrl+C to close it

Insufficient number of arguments or no entry found.
Alternatively, run 'webpack(-cli) --help' for usage info.

Technical info

• Webpack Bundle Analyzer version: 3.6.1
• Webpack version: 4
• Node.js version: 12.6.1
• npm/yarn version:
• OS: Windows

Debug info

How do you use this module? As CLI utility or as plugin? Plugin

If CLI, what command was used? (e.g. webpack-bundle-analyzer -O path/to/stats.json)

If plugin, what options were provided? (e.g. new BundleAnalyzerPlugin({ analyzerMode: 'disabled', generateStatsFile: true }))

const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
module.exports = {
  plugins: [
    new BundleAnalyzerPlugin()
  ]
}

What other Webpack plugins were used?

"webpack": "^4",
    "webpack-bundle-analyzer": "^3.6.1",
    "webpack-cli": "^3",
    "webpack-dev-server": "^3"

It would be nice to also attach webpack stats file. It can be generated using these options:

new BundleAnalyzerPlugin({
  analyzerMode: 'disabled',
  generateStatsFile: true,
  // Excludes module sources from stats file so there won't be any sensitive data
  statsOptions: { source: false }
})

stats.json will be created in Webpack bundle output directory.

Hi, thanks for opening the issue.

This part of the command output seems interesting:

Insufficient number of arguments or no entry found.
Alternatively, run 'webpack(-cli) --help' for usage info.

It seems like webpack itself is unable to generate your bundle. When webpack fails to generate a bundle, webpack-bundle-analyzer won't have output files to read the bundle contents from.

Hello @valscion , Thank you for your feedback! I did make a couple of changes ,end up with a successful compile and the following, but still no parsed files?

Read Troubleshooting section of the readme please.

Looks like you're using webpack-dev-server. That's why you don't have bundles to parse, as no files are emitted. See the readme, https://github.com/webpack-contrib/webpack-bundle-analyzer/issues/191 and https://github.com/webpack-contrib/webpack-bundle-analyzer/issues/147 for example.

When I used npm scripts to build my Vue 2 project, the JavaScript files in the 'dist' directory were not minified, and remained at their original size，only stat，not have parsed and gzip
