Storybook 5 Sass-loader generate empty module classname - sass

I recently upgraded tom Next.js 11 and so I use the storybook webpack5 beta as well. But when I add the sass-loader to the config:
// .storybook/main.js
const path = require('path');
module.exports = {
core: {
builder: "webpack5",
},
stories: ['../stories/*.stories.#(ts|tsx|js|jsx|mdx)'],
addons: ['#storybook/addon-links', '#storybook/addon-essentials'],
webpackFinal: async (config, { configType }) => {
config.module.rules.push({
test: /\.s[ac]ss$/i,
use: [
"style-loader",
"css-loader",
"sass-loader",
],
},);
return config;
},
}
So when I start storybook then, the example has no className at all:
And the .index class has not compiled by sass like it should in a module:
To see it yourself you can checkout my example here

For Storybook you can use the Storybook Saas Addon which works just fine.

Laravel + VueJs + Webpack + Karma = world of pain

Is it possible to write unit tests for VueJs if you are using Laravel's Elixir for your webpack configuration?
VueJs 2x has a very simple example for a component test: Vue Guide Unit testing
<template>
<span>{{ message }}</span>
</template>
<script>
export default {
data () {
return {
message: 'hello!'
}
},
created () {
this.message = 'bye!'
}
}
</script>
and then...
// Import Vue and the component being tested
import Vue from 'vue'
import MyComponent from 'path/to/MyComponent.vue'
describe('MyComponent', () => {
it('has a created hook', () => {
expect(typeof MyComponent.created).toBe('function')
})
it ...etc
})
and gives an example of a karma conf file here: https://github.com/vuejs-templates
But the Karma configuration file requires a webpack configuration file
webpack: webpackConfig,
The only problem is the Laravel's Elixir is creating the webpack configuration so it can't be included.
I have tried creating another webpack configuration file based on the example from https://github.com/vuejs-templates/webpack.
Something like this:
var path = require('path');
var webpack = require('webpack');
module.exports = {
entry: './src/main.js',
output: {
path: path.resolve(__dirname, './dist'),
publicPath: '/dist/',
filename: 'build.js'
},
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader',
options: {
loaders: {
// Since sass-loader (weirdly) has SCSS as its default parse mode, we map
// the "scss" and "sass" values for the lang attribute to the right configs here.
// other preprocessors should work out of the box, no loader config like this necessary.
'scss': 'vue-style-loader!css-loader!sass-loader',
'sass': 'vue-style-loader!css-loader!sass-loader?indentedSyntax'
}
// other vue-loader options go here
}
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.(png|jpg|gif|svg)$/,
loader: 'file-loader',
options: {
name: '[name].[ext]?[hash]'
}
}
]
},
resolve: {
alias: {
'vue$': 'vue/dist/vue.esm.js'
}
},
devServer: {
historyApiFallback: true,
noInfo: true
},
performance: {
hints: false
},
devtool: '#eval-source-map'
}
and included it like...
// Karma configuration
// Generated on Wed Mar 15 2017 09:47:48 GMT-0500 (CDT)
var webpackConf = require('./karma.webpack.config.js');
delete webpackConf.entry;
module.exports = function(config) {
config.set({
webpack: webpackConf, // Pass your webpack.config.js file's content
webpackMiddleware: {
noInfo: true,
stats: 'errors-only'
},
But I am getting errors that seem to indicate that webpack isn't doing anything.
ERROR in ./resources/assets/js/components/test.vue
Module parse failed: /var/www/test/resources/assets/js/components/test.vue Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
| <template>
| <span >{{test}}</span>
| </template>
Ok, I got this to work. Couple of things that might help.
I was originally running gulp, and trying to run tests in my vagrant box, to try to match the server configuration. I think that makes it much harder to find examples and answers on the internet.
Ok, so the main problem I was having is that webpack wasn't processing my components included in my test files. I copied the webpack config out of the laravel-elixir-vue-2/index.js node module directly into the Karma configuration file and it started working.
The key is that karma-webpack plugin needs both the resolve and module loader configuration settings (resolve with alias and extensions) for it to work.
Hope this helps someone.
karma.conf.js:
module.exports = function (config) {
config.set({
// to run in additional browsers:
// 1. install corresponding karma launcher
// http://karma-runner.github.io/0.13/config/browsers.html
// 2. add it to the `browsers` array below.
browsers: ['Chrome'],
frameworks: ['jasmine'],
files: ['./index.js'],
preprocessors: {
'./index.js': ['webpack']
},
webpack: {
resolve: {
alias: {

},
extensions: ['.js', '.vue']
},
vue: {
buble: {

{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
loader: 'file-loader',
query: {
limit: 10000,
name: '../img/[name].[hash:7].[ext]'
}
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
loader: 'url-loader',
query: {

noInfo: true,
},
coverageReporter: {
dir: './coverage',
reporters: [
{ type: 'lcov', subdir: '.' },
{ type: 'text-summary' },
]
},
});
};
I ran into the exact same problem. The accepted answer did not fully work for me. The following solved my issue:
Install relevant loaders for webpack:
npm install --save-dev vue-loader file-loader url-loader
Create webpack config file (note the format). The accepted answer produced errors citing invalid format of the webpack.config.js file. At least with me it did.
webpack.config.js
module.exports = {
module: {
rules: [
{
test: /\.vue$/,
use: [
{ loader: 'vue-loader' }
]
},
{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
use: [
{
loader: 'file-loader',
query: {
limit: 10000,
name: '../img/[name].[hash:7].[ext]'
}
}
]
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
use: [
{
loader: 'url-loader',
query: {
limit: 10000,
name: '../fonts/[name].[hash:7].[ext]'
}
}
]
}
]
}
}
karma.conf.js
// Karma configuration
var webpackConf = require('./webpack.config.js');
delete webpackConf.entry
module.exports = function(config) {
config.set({
frameworks: ['jasmine'],
port: 9876, // web server port
colors: true,
logLevel: config.LOG_INFO,
reporters: ['progress'], // dots, progress
autoWatch: true, // enable / disable watching files & then run tests
browsers: ['Chrome'], //'PhantomJS', 'Firefox',
singleRun: true, // if true, Karma captures browsers, runs the tests and exits
concurrency: Infinity, // how many browser should be started simultaneous
webpack: webpackConf, // Pass your webpack.config.js file's content
webpackMiddleware: {
noInfo: true,
stats: 'errors-only'
},
/**

*/
basePath: './resources/assets/js/',
/**

files: [
{pattern: 'tests/*.js', watched: false},
{pattern: 'tests/**/*.js', watched: false}
],
// list of files to exclude
exclude: [
],
/**

* Add your App entry point as well as your Tests files which should be

*/
preprocessors: {
'app.js': ['webpack', 'babel'],

}
Then run karma start and everything should work.

Webpack 1.x Hot Module Replacement Modules not updating

I'm trying to integrate Angular 2 with HMR in Visual Studio 2015. I have 2 projects with the same file contents and same directory structure and both uses HMR with Angular 2. But the HMR for each project looks for different to update the bundle. i.e. For App1, it looks for Typescript files (And JS are not generated for them in VS) like:
Having Module A depends upon B, and B Upon C. If C is updated, the whole bundle gets updated that works good.
But in App2, it looks for 1 Typescript file main.ts and 2 Javascript files, like:
If C is updated, the module don't get updated, unless I explicitly modify C's Javascript file (Generated by VS on build)!
How do I tell Webpack HMR to look for these Typescript files and update the bundle if I changed any of them.
My webpack.config.js are same for both projects like:
var path = require('path');
var webpack = require('webpack');
module.exports = {
resolve: { extensions: [ '', '.js', '.ts' ] },
entry: { 'main-client': './ClientApp/main.ts' },
output: {
filename: '[name].js',
path: path.join(__dirname, './wwwroot/dist'),
publicPath: '/dist/'
},
module: {
loaders: [
{ test: /\.ts$/, include: /ClientApp/, loader: 'ts' },
{ test: /\.html$/, loader: 'raw' }
]
}
};
I had the same problem and fixed it by enabling HMR in main.ts.
import { platformBrowserDynamic } from '#angular/platform-browser-dynamic';
import { enableProdMode } from '#angular/core';
import { AppModule } from './app/app.module';
// Enables Hot Module Replacement.
declare var module: any;
if (module.hot) {
module.hot.accept();
}
platformBrowserDynamic().bootstrapModule(AppModule);

"transform-es3-member-expression-literals" usage in webpack 1.x

I am working on application that needs to be run on IE 8 enterprise version.I am getting following errors in the console:
Expected identifier : ;
indexOf is not available for the object.
For solving this I read this question on stackoverflow:
Babel 6.0.20 Modules feature not work in IE8
It suggests
transform-es3-member-expression-literals
transform-es3-property-literals
to be added.
But using this in webpack is not mentioned any where,not on babel official site.
Can anyone suggest the way how can I use it as a plugin to my project.
Note:I have already tried doing
var es3MemberExpressionLiterals = require('babel-plugin-transform-es3-member-expression-literals');
var es3PropertyLiterals = require('babel-plugin-transform-es3-property-literals');
plugins = [// Plugins for Webpack
new webpack.optimize.UglifyJsPlugin({minimize: false}),
new HtmlWebpackPlugin({
template: 'index.html', // Move the index.html file...
minify: { // Minifying it while it is parsed using the following, self–explanatory options
removeComments: false,
collapseWhitespace: false,
removeRedundantAttributes: false,
useShortDoctype: false,
removeEmptyAttributes: false,
removeStyleLinkTypeAttributes: false,
keepClosingSlash: true,
minifyJS: false,
minifyCSS: true,
minifyURLs: false
}
})
new es3MemberExpressionLiterals(),
new es3PropertyLiterals()
];
I've created a demo repository on github to show the full configuration by an example.
To get the two plugins running create a .babelrc file, with the following content
{
"plugins": [
"transform-es3-member-expression-literals",
"transform-es3-property-literals"
]
}
In the standard configuration babel-loader in your webpack.config.js babel takes a look into the .babelrc to configure plugins.
// webpack.config.js (partial code only)
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
}
]
}
If everything is set up correctly webpack should transform the following code
// src/main.js
var foo = { catch: function() {} };
console.log(foo.catch)
into
// bundle.js
/* 0 */
/***/ function(module, exports) {
var foo = { "catch": function () {} };
console.log(foo["catch"]);
/***/ }
See also the examples for the plugins: babel-plugin-transform-es3-property-literals and babel-plugin-transform-es3-member-expression-literals.
The question you link to is about Babel plugins, and you are trying to pass them as Webpack plugins. You'd need to set up Babel as a loader for your application and pass the plugins to that. Merge the following into your Webpack configuration.
module: {
loaders: [{
loader: 'babel',
test: /\.js$/,
exclude: /node_modules/,
plugins: [
'babel-plugin-transform-es3-member-expression-literals',
'babel-plugin-transform-es3-property-literals',
],
}],
},

Error when combining sass-loader with css-modules

I'm getting the following error when using SASS's map-get.
ERROR in ./src/special.scss
Module build failed: ModuleBuildError: Module build failed: Unknown word (11:14)
9 |
10 | #mixin mediaquery($name) {
> 11 | #media #{map-get($breakpoints, $name)} {
| ^
12 | #content;
13 | }
14 | }
This is only happening when I use both the sass-loader and another loader.
I first thought this was caused by the PostCSS Loader, but it seems like it's the sass-loading causing problems and not transforming the scss when using css-modules.
I've created a sample repo illustrating the problem: https://github.com/tiemevanveen/sass-css-components-fail-example.
You can use the different branches to test:
master: CSS Modules + SASS
postcss CSS Modules + SASS + PostCSS
log-source: Uses CSS modules + SASS + Custom source logging module
no-css-modules: SASS + Custom source logging module
Only the first and the last branch run without errors.
I've created the log-source example to see what the sass-loader is returning and it looks like it's not transforming the sass (but this might also be me misinterpreting how the loaders work).
The other example without css modules does show the right transformed code..
I'm puzzled why the master branch (without postcss or another custom loader) is working fine though.. if something would be wrong with the sass-loader then that one should also fail right?
I've filed an issue, but I'm thinking this has more chance on StackOverflow since it's such a specific problem and might be more a config problem. Here's my webpack config:
const webpack = require('webpack');
const path = require('path');
const autoprefixer = require('autoprefixer');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const WriteFilePlugin = require('write-file-webpack-plugin');
module.exports = {
devtool: 'source-source-map',
debug: true,
context: path.resolve(__dirname, './src'),
entry: {
app: './index.js'
},
output: {
path: path.resolve(__dirname, './static'),
filename: '[name].js',
publicPath: '/static/'
},
devServer: {
outputPath: path.resolve(__dirname, './static'),
},
plugins: [
new webpack.NoErrorsPlugin(),
new ExtractTextPlugin('[name].css'),
new WriteFilePlugin()
],
module: {
loaders: [
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('style-loader', [
'css?modules&importLoaders=1&localIdentName=[path]_[name]_[local]',
// 'postcss-loader',
'sass'
])
},
// + js loader
]
},
postcss: [
autoprefixer({ browsers: ['> 0.5%'] })
],
resolveLoader: {
fallback: [
path.resolve(__dirname, 'loaders'),
path.join(process.cwd(), 'node_modules')
]
},
resolve: {
extensions: ['', '.js', '.json'],
}
};
You need to increase the importLoaders query parameter as you add loaders. That feature is poorly documented and confusing, but in your samples repo, importLoaders=2 with both Sass and PostCSS works.
