Ignore-emit-webpack-plugin NPM

Ignore Emit Webpack plugin

Prevent files that are matching a pattern from being emitted in a webpack build. This is achieved with a webpack plugin.

You can easily ignore file by accident - use with care.

Quick Usage

npm i --save-dev ignore-emit-webpack-plugin

Typescript

// webpack.config.js
import IgnoreEmitPlugin from 'ignore-emit-webpack-plugin';

export default {
  // ...
  plugins: [
    new IgnoreEmitPlugin(/\.map$/)
  ]
};

// webpack.config.js
const IgnoreEmitPlugin = require('ignore-emit-webpack-plugin');

module.exports = {
  // ...
  plugins: [ new IgnoreEmitPlugin(/\.map$/) ]
  // ...
};

The module is written in Node 8.x flavored es6. To get the es5 transpiled version use require('ignore-emit-webpack-plugin/es5')

Usage

Signature: new IgnoreEmitPlugin(patterns, options)

patterns {RegExp|string|Array.<RegExp|string>} - regex, string or array with mixed regex/strings (deep nesting allowed), to match against the OUTPUT path of assets.
options {object} - optional, options object
- options.debug {boolean} - prints extra logs

not defining patterns or defining invalid pattern will throw error.

// single regex
new IgnoreEmitPlugin(/\/artifacy.js$/);
// single regex in array
new IgnoreEmitPlugin([ /\/artifacy.js$/ ]);
// mixed array
new IgnoreEmitPlugin([ 'file.woff', /\/artifacy.js$/ ]);

// you can also do this - but you really shouldn't
new IgnoreEmitPlugin([ [ [ [ /\/artifacy.js$/ ] ] ] ]);


// file.js
// dir/file.js

new IgnoreEmitPlugin('file.js');     // both file.js and dir/file.js ignored
new IgnoreEmitPlugin(/\/file\.js/);  // only dir/file.js is ignored
new IgnoreEmitPlugin(/^file\.js/);   // only file.js is ignored
