webpack not working?

Question

webpack

The tutorial in webpack setup says

new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin()

But when I run npm start I get this:

> [email protected] start /Users/alexandermarginal/WebstormProjects/redux
> node server.js
/Users/alexandermarginal/WebstormProjects/redux/webpack.config.js:19
new webpack.NoErrorsPlugin()
^

If I comment these plugins, the error looks like this:

WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
- configuration.module has an unknown property 'loaders'. These properties are valid:
object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, noParse?, rules?, defaultRules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, unsafeCache?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp ?, strictExportPresence?, strictThisContextOnImports? }

All errors point to the webpack config connection string and to the webpack js file itself

NoErrorsPlugin is considered obsolete and renamed to NoEmitOnErrorsPlugin: link
ps I am aware that the question is old, but it's not nice to leave it unanswered, suddenly it will come in handy for someone.
