Prefix React className - reactjs

So, I need to prefix my react components classNames so it doesn't conflict with global classes.
And no, I can't use CSS modules because of how my yarn workspaces are built
So, if I have a button class I would like it to become my_app-button
<button className="button">Hello StackOverflow</button>
to
<button className="my-app_button">Hello StackOverflow</button>
PostCSS does that for me in the CSS part, but on the React Side I wasn't able to find a solution
All of my components use typescript
I've tried using a webpack loader to do the job, and it did! But only on my Storybook server, when I used it with my separate webpack config it didn't work
The only error that is given to me is invariant 85
This is my Webpack Config, alongside the webpack loader and the babel-loader
import { Configuration, ProgressPlugin } from 'webpack'
const config: Configuration = {
mode: 'production',
entry: './src/index.ts',
target: 'node',
output: {
filename: '[name].js',
path: __dirname + '/dist',
publicPath: '',
},
resolve: {
extensions: ['.js', '.jsx', '.ts', '.tsx'],
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
use: [
{
loader: 'babel-loader',
options: {
presets: ['#babel/preset-react', '#babel/preset-env', 'minify'],
},
},
],
},
{
test: /\.tsx?$/,
exclude: /node_modules/,
use: [
{
loader: 'babel-loader',
options: {
presets: [
'#babel/preset-react',
'#babel/preset-env',
'#babel/preset-typescript',
'minify',
],
},
},
],
},
{
test: /\.tsx$/,
exclude: /node_modules/,
use: [
{
loader: 'react-classname-prefix-loader?prefix=giffy_css',
},
],
},
{
test: /\.(png|jpe?g|gif)$/,
exclude: /node_modules/,
use: [{ loader: 'file-loader' }],
},
],
},
plugins: [new ProgressPlugin()],
}
export default config
and just in case you need it, this is my Storybook webpack configuration
webpackFinal: async (config, { configType }) => {
config.module.rules.push({
test: /\.tsx$/,
exclude: /node_modules/,
use: [
{
loader: 'react-classname-prefix-loader?prefix=giffy_css',
},
],
})
// console.log(config.module.rules[0].use[0].options.overrides[0])
return config
}
i have also tried first compiling my components with babel and then using webpack
i tried searching for an equivalent webpack loader in babel, but could not find it

Webpack not picking up imports of scss files in react components

I want to set up my react project with an scss file for each component. So given a component called PermissionPicker I want to import a PermissionPicker.scss in the jsx file.
With my current set up the webpack loaders are only loading scss files when imported in my entry point (boot-client.tsx). import './PermissionPicker.scss' in my PermissionPicker components causes a webpack error:
Module parse failed: PermissionPicker.scss Unexpected token (1:1)
You may need an appropriate loader to handle this file type.
I was under the impression that I could import scss anywhere in my project similar to how create-react-app works.
Any advice would be great!
Below is my webpack config.
const sharedConfig = () => ({
stats: { modules: false },
resolve: { extensions: [ '.js', '.ts', '.tsx', '.jsx' ] },
output: {
filename: '[name].js',
publicPath: '/dist/' /
},
module: {
rules: [
{ test: /\.tsx?$/, include: /client/, use: 'babel-loader' },
{ test: /\.tsx?$/, include: /client/, use: 'awesome-typescript-loader?silent=true' }
]
},
plugins: [new CheckerPlugin()]
});
const clientBundleOutputDir = './wwwroot/dist';
const clientBundleConfig = merge(sharedConfig(), {
entry: { 'main-client': './client/boot-client.tsx' },
module: {
rules: [
{ test: /\.css$/, use: ExtractTextPlugin.extract({ use: 'css-loader' }) },
{ test: /\.scss$/, use: ExtractTextPlugin.extract({
use: [{
loader: "css-loader"
}, {
loader: "sass-loader"
}],
fallback: "style-loader"
})
},
{ test: /\.(png|jpg|jpeg|gif|svg)(\?\S*)?$/, use: 'url-loader?limit=25000' }
]
},
output: { path: path.join(__dirname, clientBundleOutputDir) },
plugins: [
new ExtractTextPlugin('site.css'),
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('./wwwroot/dist/vendor-manifest.json')
})
].concat(isDevBuild ? [
new webpack.SourceMapDevToolPlugin({
filename: '[file].map',
moduleFilenameTemplate: path.relative(clientBundleOutputDir, '[resourcePath]')
})
] : [
])
});
You need to install node-sass with sass-loader, because the sass-loader requires node-sass as peerDependency
npm install sass-loader node-sass --save-dev
And missing something as include: join(__dirname, 'src')
rules: [
{
test: /\.css$/,
include: join(__dirname, 'src'),
use: ExtractTextPlugin.extract({ use: 'css-loader' })
},
{
test: /\.scss$/,
include: join(__dirname, 'src'),
use: ExtractTextPlugin.extract({
use: [{
loader: "css-loader"
}, {
loader: "sass-loader"
}],
fallback: "style-loader"
})
},
{ test: /\.(png|jpg|jpeg|gif|svg)(\?\S*)?$/, use: 'url-loader?limit=25000' }
]
The src is a common path for Components, you need to indicate the path from the path of your config file

How to enable babel stage-0 in webpack config file

I used the below-mentioned command:
npm install --save-dev babel-preset-stage-0
Now I added it in webpack.config.js file as shown below:
module.exports = {
entry: './app/app.jsx',
output: {
path: __dirname,
filename: './public/bundle.js'
},
resolve: {
root: __dirname,
alias: {
},
extensions: ['', '.js', '.jsx']
},
module: {
loaders: [
{
loader: 'babel-loader',
query: {
presets: ['react', 'es2015', 'stage-0']
},
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/
}
]
}
};
But Now when I run webpack command it shows some error. Please check error:
Error image:
If you are not using a .babelrc file, add babelrc: false like so:
module: {
loaders: [
{
loader: 'babel-loader',
babelrc: false, // <--- Add this
query: {
presets: ['react', 'es2015', 'stage-0']
},
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/
}
]
}
I recommend using the create-react-app CLI if you don't want to deal with the headache of setting up a development environment boilerplate. I just started using it and it is great!

React bootstrap not rendering style

Bootstrap styles not rendering when everything is setup fine. I have install react-bootstrap and imported bootstrap css, but i cannot get the style to render. I can make it work through a create-react-app boilerplate. I suspect that it has something to do with my bootstrap. this is my webpack.config file:
var path = require('path');
var webpack = require('webpack');
module.exports = {
devServer: {
inline: true,
contentBase: './src',
port: 3000
},
devtool: 'cheap-module-eval-source-map',
entry: './dev/js/index.js',
module: {
loaders: [
{
test: /\.js$/,
loader: 'babel',
query: {
presets: ['es2015', 'react', 'stage-0']
},
exclude: /node_modules/
},
{
test: /\.css$/,
loaders: [
'style?sourceMap',
'css?modules&importLoaders=1&localIdentName=[path]___[name]__[local]___[hash:base64:5]'
]
},
{
test: /\.(png|jpg)$/,
loader: 'url?limit=25000'
}
]
},
output: {
path: 'src',
filename: 'js/bundle.min.js'
},
plugins: [
new webpack.optimize.OccurrenceOrderPlugin()
]
};

Error while build my react app (UglifyJs)

When i run build of my react app i got: ERROR in bundle.js from UglifyJs
Unexpected token: name i found this https://github.com/joeeames/WebpackFundamentalsCourse/issues/3
they suggest use babel-reset-es2015 but i need babel-preset-react.
My webpack config:
const path = require('path')
const ExtractTextPlugin = require("extract-text-webpack-plugin")
const extractSass = new ExtractTextPlugin({
filename: "style.css",
disable: process.env.NODE_ENV === "development"
});
const config = {
entry: "./src/index.js",
output: {
filename: "bundle.js",
path: path.resolve(__dirname + "/dist")
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: "babel-loader",
query: {presets:['react']}
},
{
test: /\.js$/,
enforce: 'pre',
loader: 'eslint-loader',
options: {
emitWarning: true,
}
},
{ test: /\.html$/,
use:[{
loader: 'html-loader',
options: {
minimize:true
}
}]
},
{
test: /\.scss$/,
use: extractSass.extract({
use: [{
loader: "css-loader"
}, {
loader: "sass-loader"
}],
fallback: "style-loader"
})
}
]},
plugins: [
extractSass
],
node:{
fs: "empty"
}
}
module.exports = config
You can have both, they are not mutually exclusive. Also query has been replaced with options in webpack 2, just as you're using it in your other loaders already. query still exists for compatibility reasons, but you should just use options.
{
test: /\.js$/,
exclude: /node_modules/,
loader: "babel-loader",
options: {
presets: ['es2015', 'react']
}
},

Using react-infinite-calendar with css-modules

I'd like to use react-infinite-calendar component for a personal project. It's not picking up the css. I think my webpack configuration is the problem as I'm using react-css-modules.
Could someone show me what I'd need to do to get it working?
My webpack configuration is:
const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');
module.exports = {
entry: './index.js',
context: path.join(__dirname, 'client'),
devtool: 'source-map',
output: {
path: './dist/client/',
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.json$/,
loader: 'json-loader'
},
{
// https://github.com/gajus/react-css-modules
test: /\.css$/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
}
]
},
resolve: {
extensions: ['', '.js', '.json']
},
plugins: [
new CopyWebpackPlugin([
{from: 'static/index.html'}
])
]
};
My date selector component is:
import React from 'react';
import InfiniteCalendar from 'react-infinite-calendar';
import 'react-infinite-calendar/styles.css'; // only needs to be imported once
import {TODAY} from '../../server/constants/date';
export default class DateSelector extends React.Component {
render() {
return (
<div>
<InfiniteCalendar
width={400}
height={600}
selectedDate={TODAY}
maxDate={TODAY}
/>
</div>
);
}
}
Another option is to exclude react-infinite-calendar from your CSS module loader and include it in the standard CSS loader.
That way you don't have to rename all of your CSS files.
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.css$/,
exclude: /react-infinite-calendar/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]',
},
{
test: /\.css$/,
include: /react-infinite-calendar/,
loader: 'style-loader!css-loader',
},
]
I worked around this by having to separate webpack loaders for locally scoped css-modules and globally scoped ones. My webpack configuration is below and so for css modules I've had to name the files so they end with .module.css.
const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');
module.exports = {
entry: './index.js',
context: path.join(__dirname, 'client'),
devtool: 'source-map',
output: {
path: './dist/client/',
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.json$/,
loader: 'json-loader'
},
{
// https://github.com/gajus/react-css-modules
test: /\.module.css$/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
},
{
test: /^((?!\.module).)*css$/,
loader: 'style-loader!css-loader'
},
]
},
resolve: {
extensions: ['', '.js', '.json']
},
plugins: [
new CopyWebpackPlugin([
{from: 'static/index.html'}
])
]
};
