disable-output-webpack-plugin

1.0.1 verified Sat Apr 25 auth: no javascript

Webpack plugin that prevents saving output files to disk, useful for scenarios where you only need webpack's in-memory compilation (e.g., with webpack-dev-server or custom runners). Version 1.0.1 is current, no frequent releases. Simple no-config plugin, lighter than alternatives like `webpack-disk-plugin`. Likely no longer needed with webpack 5's `output.writeToDisk` option.

Common errors

error TypeError: DisableOutputWebpackPlugin is not a constructor ↓

cause Using ES module import syntax (`import DisableOutputWebpackPlugin from ...`) which doesn't resolve to the CommonJS export correctly.

fix

Use const DisableOutputWebpackPlugin = require('disable-output-webpack-plugin') instead of import.

error Module not found: Error: Can't resolve 'disable-output-webpack-plugin' ↓

cause Package not installed or missing from node_modules.

fix

Run npm install --save-dev disable-output-webpack-plugin.

error Error: You forgot to add 'mini-css-extract-plugin' plugin ↓

cause Not related to this plugin; it's a common confusion with other plugins.

fix

Ensure other plugins like MiniCssExtractPlugin are properly configured if used.

Warnings

gotcha The plugin only works with webpack 4 and lower; webpack 5 has native support via `output.writeToDisk: false`. ↓

fix Use webpack 5's built-in `output.writeToDisk: false` instead.

gotcha The constructor accepts no options; passing any argument will be silently ignored. ↓

fix Remove any arguments from `new DisableOutputWebpackPlugin()`.

gotcha If using webpack-dev-server, output is already not written to disk by default, making this plugin redundant. ↓

fix Remove the plugin; webpack-dev-server handles in-memory compilation.

Install

npm install disable-output-webpack-plugin

yarn add disable-output-webpack-plugin

pnpm add disable-output-webpack-plugin

Imports

DisableOutputWebpackPlugin

wrong

import DisableOutputWebpackPlugin from 'disable-output-webpack-plugin'

correct

const DisableOutputWebpackPlugin = require('disable-output-webpack-plugin')

Package does not export ES modules correctly; use CommonJS require.

default

wrong

const { DisableOutputWebpackPlugin } = require('disable-output-webpack-plugin')

correct

const DisableOutputWebpackPlugin = require('disable-output-webpack-plugin')

The package exports a single constructor function, not a named export.

new
wrong
```
new DisableOutputWebpackPlugin({})
```
correct
```
new DisableOutputWebpackPlugin()
```
The constructor takes no arguments; passing options will be ignored.

Quickstart

Basic setup to disable webpack output file writing. Note: output.path is still needed but files are not saved.

// webpack.config.js
const DisableOutputWebpackPlugin = require('disable-output-webpack-plugin');

module.exports = {
  entry: './src/index.js',
  output: {
    path: '/dev/null', // still required but output won't be written
    filename: 'bundle.js'
  },
  plugins: [
    new DisableOutputWebpackPlugin()
  ]
};
