Webpack Remove Block
===================

Webpack loader to remove blocks of code marked by special comment tags. Useful for removing code that you don't want in your production webpack bundle (e.g. verbose console warnings, etc).

Support multiple block types.

In your client js source files:

``javascript
/ debug:start /
console.log('debug');
/ debug:end /

var makeFoo = function(bar, baz) {
// The following code will be removed with our webpack loader
/ develblock:start /
if (bar instanceof Bar !== true) {
throw new Error('makeFoo: bar param is required and must be instance of Bar');
}
/ develblock:end /

// This code would remain
return new Foo(bar, baz);
}

`html

In your webpack config, specify the loader:

`javascript
var blocks = [{
block: 'develblock',
start: '/*',
end: '*/'
}, {
block: 'develblock',
start: ''
}, {
block: 'develblock2',
start: '//'
}, 'develblock3'];

if (process.env.NODE_ENV === 'development') {
blocks.push({
block: 'debug',
start: '/*',
end: '*/'
});
}

module.exports = {
module: {
rules: [
{
test: /\.js$/,
enforce: 'pre',
exclude: /(node_modules|bower_components|\.spec\.js)/,
use: [{
loader: 'webpack-remove-blocks',
options: {
blocks: ['develblock', {
block: 'develblock',
start: '//'
}]
}
}]
}, {
test: /\.html$/,
enforce: 'pre',
use: [{
loader: 'webpack-remove-blocks',
options: {
blocks: blocks
}
}]
}
]
}
};

let mix = require( 'laravel-mix' );
