问题
I am trying to load a image:
background: transparent url("../img/select-icon.png") no-repeat center right 8px;
At my style.scss and it is not working
Here is my webpack.config:
function _path(p) {
return path.join(__dirname, p);
}
module.exports = {
context: __dirname,
entry: [
'./assets/js/index'
],
output: {
path: path.resolve('./assets/bundles/'),
filename: '[name].js'
},
devtool: 'inline-eval-cheap-source-map',
plugins: [
new BundleTracker({filename: './webpack-stats.json'}),
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery'
}),
new HappyPack({
id: 'jsx',
threads: 4,
loaders: ["babel-loader"]
})
],
module: {
loaders: [
{
test: /\.css$/,
include: path.resolve(__dirname, './assets/css/'),
loader: "style-loader!css-loader"
},
{
test: /\.scss$/,
include: path.resolve(__dirname, './assets/css/'),
loader: "style-loader!css-loader!sass-loader"
},
{
test: /\.jsx?$/,
include: path.resolve(__dirname, './assets/js/'),
exclude: /node_modules/,
loaders: ["happypack/loader?id=jsx"]
},
{
test: /\.png$/,
loader: 'file-loader'
}
]
},
resolve: {
modulesDirectories: ['node_modules'],
extensions: ['', '.js', '.jsx'],
alias: {
'inputmask' : _path('node_modules/jquery-mask-plugin/dist/jquery.mask'),
},
}
}
I am using file-loader but the url rendered at browser does not match with the url of the image.
I think that I not using source map: https://github.com/webpack/style-loader/issues/55
Can anyone help?

To resolve the url('...') to the file output path you need to use resolve-url-loader
before the css-loader
.
In your webpack.config.js
you need to make the following changes:
//...
module: {
loaders: [
{
test: /\.css$/,
include: path.resolve(__dirname, './assets/css/'),
loader: "style-loader!css-loader!resolve-url-loader"
},
{
test: /\.scss$/,
include: path.resolve(__dirname, './assets/css/'),
loader: "style-loader!css-loader!resolve-url-loader!sass-loader"
},
//...
]
}
//...
As an optional configuration, you can specify the filename template that the file-loader
uses. So instead of having 96ab4c4434475d0d23b82bcfc87be595.png
for instance, you can have /img/select-icon.png
.
In your webpack.config.js
the default options of the file-loader
are being used. This means that the output filename is using the template [id].[ext]
. Being [id]
the chunk id and [ext]
the extension of the file.
To specify the output filename template you need to pass the name
parameter to the query of the loader.
Up to this point, require('../img/select-icon.png')
should return '/img/select-icon.png'
. The resolve-url-loader
will use this value.
//...
module: {
loaders: [
//...
{
test: /\.png$/,
loader: 'file-loader',
query: {
name: 'img/[name].[ext]'
}
},
//...
]
}
//...

I use the Angular Class starter Pack so I don't know if you have the "helpers" class available.
within the webpack congif / common add a helper constant.
const helpers = require('./helpers');
within your resolve: add
root: helpers.root('src'),
and within the loaders add:
{
test: /\.html$/,
loader: 'raw-loader',
exclude: [helpers.root('src/index.html')]
},
now change the scss loader to this
{
test: /\.scss$/,
exclude: /node_modules/,
loaders: ['raw-loader', 'sass-loader']
},
Now im not sure if your still able to use "include.path" I just add "assets" within the Url like so "url ('./assets/img/whatever.png').
Hope that helps and good luck.
