Debugging Webpacker config

Option 1: JSON dump

In config/webpack/environment.js you can get inspect environment which includes all webpack config options set for the current environment:

Copy
const { environment } = require('@rails/webpacker') const webpack = require('webpack') throw JSON.stringify(environment, null, 2) ...

Option 2: Browser console

You can also debug the config in your browser directly with a newer version of Webpacker:

Copy
process.env.NODE_ENV = process.env.NODE_ENV || 'development' const environment = require('./environment') const webpackConfig = environment.toWebpackConfig() debugger module.exports = webpackConfig

Then run bin/webpack --debug and a browser window will be opened if you have a node debugger installed Archive .

Option 3: Node console

Copy
$ RAILS_ENV=development node const config = require('./config/webpack/development')
