Invalid path ''

[karlas]

Hi,

I'm experiencing this error, and I can't guess how to solve it.

Error trace is:

/home/karlas/code/kaitocat/node_modules/hapi-webpack-plugin/node_modules/webpack-dev-middleware/middleware.js:104
            if(err) throw err;

This appears some seconds after registering, not inmediately. Register code is, at /src/server/index.js file of my project

  server.register(
  {
    register : require('hapi-webpack-plugin'),
    options  : path.join(__dirname, '../../webpack.config.js')
  }, function(err)
  {
    if (err)
    {
      return console.error(err);  //this is not reached
    }
  });

Webpack-dev-server is working fine when executing standalone via terminal. Could the problem be to have files in different paths? (webpack.config.js is at root of project)

Thanks in advance

By setting:

options : '../../webpack.config.js'

Error is :

Error: Configuration not found at ../../webpack.config.js

and setting

options : '.webpack.config.js'

Error is the same "Invalid path" error. So I guess path is relative from root of project

[SimonDegraeve]

Indeed, path is relative to process.cwd(), could be confusing. Maybe I should allow only absolute path...

[karlas]

Thanks for you time!

Unfortunately i'm getting same error (Invalid path "") and same trace.

Any clue?

[SimonDegraeve]

Can you share your webpack.config.js file?

[karlas]

Sure :

// webpack.config.js
var webpack = require('webpack');
var path    = require('path');
var isDev   = (process.env.NODE_ENV === 'dev');

var config  =
{
  entry   : {sobrassada : './client_js/sobrassada/main.js'},
  devtool : isDev ? 'source-map' : false,
  output  : isDev ? {filename: './public/sobrassada.js'} :
  {
    path          : './public/',
    publicPath    : './public/',
    chunkFilename : '[name].js',
    filename      : '[name].js'
  },
  module:
  {
    loaders:
    [
      {
        test    : /\.jsx?$/,
        exclude : /(node_modules)/,
        loader  : isDev ? 'react-hot!babel!eslint-loader' : 'babel'
      },
      {
        test   : /\.less$/,
        loader : "style!css!less"
      },
      //Fonts
      {
        test: /\.woff(\?v=\d+\.\d+\.\d+)?$/,
        loader: "url?limit=10000&mimetype=application/font-woff"
      },
      {
        test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/,
        loader: "url?limit=10000&mimetype=application/font-woff"
      },
      {
        test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/,
        loader: "url?limit=10000&mimetype=application/octet-stream"
      },
      {
        test: /\.eot(\?v=\d+\.\d+\.\d+)?$/,
        loader: "file"
      },
      {
        test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
        loader: "url?limit=10000&mimetype=image/svg+xml"
      }
    ]
  },
  plugins:
  [
    new webpack.DefinePlugin(
    {
      'process.env' : {'NODE_ENV': JSON.stringify(process.env.NODE_ENV)},
      __DEV__       : isDev,
    }),
  ]
};

if (isDev)
{
 config.plugins.push(new webpack.HotModuleReplacementPlugin());
 config.eslint = {configFile: '.eslintrc'};
}

module.exports = config;

[SimonDegraeve]

Ok, I am pretty sure it has nothing to do with the plugin. However in your config file I can see that output.path is not absolute, and it should be.

The output directory as absolute path (required).

From webpack configuration

[karlas]

Correct ;)

In fact, in dev mode i was noy specyficing any path, just filename.

Thanks!

[SimonDegraeve]

No problem.
