如何配置Webpack输出以仅包含特定包的某些选项

Question

I have a Webpack 4 that build multiple bundles, I want to attach the output options libraryTarget & library for a single bundle only.

so it would look like this by default:

output: {
    path: path.resolve(__dirname, 'dist/js'),
    filename: '[name].[chunkhash].js',
  },

except for a single bundle, I need the following:

output: {
    path: path.resolve(__dirname, 'dist/js'),
    filename: '[name].[chunkhash].js',
    libraryTarget: 'var',
    library: '[name]'
  },

is this possible? I'm not seeing an example in the document

Answer 1

You can't do what you're asking, but you can instead use your existing configuration as a "common" configuration and extend it in another using webpack-merge :

// e.g. webpack.config.your-lib.js
module.exports = merge(require('./webpack.config.common.js'), {
  // ...entry changes...
  output: {
    libraryTarget: 'var',
    library: '[name]',
  }
})

Don't forget to make amendments to the entry in the above so the new config is building only the intended library bundles.
