Breaks on webpack 1.13.1

[dmitriid]

tl;dr Having plugin enabled breaks webpack builds somwhere in webpack-core/lib/ConcatSource.js

> npm install --save-dev webpack

This installs webpack 1.13.1

Given the following webpack.config:

var SvgStore = require('webpack-svgstore-plugin');

var config = {
    entry:   {
        app: [
            '/soma-file.js'
        ],
        lib: [
            'lodash'
        ]
    },
    output:  {
        path:              '/path',
        filename:          filename
    },
    module:  {
        loaders: [
            {
                test:   /\.js$/,
                loader: 'babel',
                query:  {
                    presets: ['es2015', 'stage-0', 'react'],
                    compact: false
                }
            },
            {
                test:   /\.json$/,
                loader: 'json'
            }
        ]
    },
    plugins: [
        new SvgStore(path.join('./img/svg', '', '**!/!*.svg'), path.join('./', ''), {
            name:        '[hash].sprite.svg',
            chunk:       'app',
            prefix:      'pref-',
            baseUrl:     '/my-url',
            svgoOptions: {}
        }),
        new webpack.optimize.CommonsChunkPlugin("lib", "lib.js", Infinity)
    ],
    bail:    false,
    target:  'web'
};

Trying to run this results in:

/node_modules/webpack-core/lib/ConcatSource.js:24
        return typeof item === "string" ? item : item.source();
                                                     ^

Will report this to webpack as well, could be a problem on their side: see webpack/core#24

Ok.. man.. I've been banging my head on this issue thinking it was something in my setup. I'm definitely experiencing this as well on 1.13.1.

The issue only occurs when I set the chunk value. If I leave the chunk value blank, the error doesn't occur, but the SVG does not build.

I'm also using the CommonsChunkPlugin as in the example above.

Hi! Can you look, this version 3.0.0-alpha.1?
code here https://github.com/mrsum/webpack-svgstore-plugin/tree/feature/refactor

I rebuild main idea.

[dmitriid]

Same problem, sadly :(

[mrsum]

@dmitriid do you red readme for this version?

[dmitriid]

@mrsum What are the differences?

The only difference I see is

put function mark at your chunk

which, honestly, I have no idea what it means :)

[mrsum]

@dmitriid try 3.0.0-alpha.2 version
documentation here https://github.com/mrsum/webpack-svgstore-plugin/blob/feature/refactor/README.md
