How to stop infinite refresh in react webpack app? - reactjs

When I change the TS file, Webpack doesn't stop refreshing the page.
Console says: #ebpack 5.66.0 compiled successfully
I've googled this and tried different plugins, but they didn't work.
The mild refresh plugin just stopping the refresh and excluding JS files from ts-loader doesn't work at all.
The related issue in git didn't give the result as well.
webpack.config.json:
const webpack = require('webpack');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

const htmlWebpackPlugin = new HtmlWebPackPlugin({
template: "./src/index.html",
filename: "./index.html",
inlineSource: '.(js|css)$',
inject: 'body',

You better change InlineChunkHtmlPlugin tests from /bundle/ to /runtime/.
Replace
new InlineChunkHtmlPlugin(HtmlWebPackPlugin, [/bundle/])
With
new InlineChunkHtmlPlugin(HtmlWebPackPlugin, [/runtime~.+[.]tsx/])
OR
new InlineChunkHtmlPlugin(HtmlWebPackPlugin, [/runtime/])

Cypress Component Testing Missing package.json

I have a React App that uses webpack and Cypress E2E testing. I'm trying to use Cypress component testing. I have written a simple test as follows:
describe('Hello World Test', () => {
it ('Button', () => {
mount(<Button>Test button</Button>)
cy.get('button').contains('Test button').click()
})
});
When I run npx cypress open-ct I get the following error:
Your pluginsFile threw an error from: .../experimentation/webpack-transition/cypress/plugins/index.js

I'm either using the wrong version of a library or I'm missing a configuration somewhere.
It looks like you configured /cypress/plugins/index.js for Create React App (CRA) but have not use it to create your react app.
From the docs Install
React (using CRA)
// cypress/plugins/index.js
module.exports = (on, config) => {
if (config.testingType === 'component') {
require('#cypress/react/plugins/react-scripts')(on, config)
}
return config
}
Instead try the Generic Webpack configuration
// cypress/plugins/index.js
module.exports = (on, config) => {
if (config.testingType === 'component') {
const { startDevServer } = require('#cypress/webpack-dev-server')
// Your project's Webpack configuration
const webpackConfig = require('../../webpack.config.js')
on('dev-server:start', (options) =>
startDevServer({ options, webpackConfig })
)
}
}

how can I solve this problem? `You may need an appropriate loader to handle this file type.` scss react

I wanna to use GoGO template in React, but i have this problem.
Uncaught Error: Module parse failed: Unexpected token (29:12)
You may need an appropriate loader to handle this file type.

Please help me, thanks in advance.
If you are using latest version of react then no need to set loader in webpack.config.js file.
You can directly do this,
npm install sass-loader
And you can start using your scss files in the project.
It is about files which start with a dot being hidden by his os and failing to copy them.
In project directory there should be a ”.babelrc” and ”.eslintrc” files and the problem occurs when ”.babelrc” file is missing. Maybe you should also check it when you have time.

Unable to configure Jest in my React App

I'm just starting with tests right now, trying to set up the Jest with my project, but it has been painful.. I am trying to do the React App tutorial, with the Webpack Tutorial, and I'm facing if this error:
C:\Users\myuser\Desktop\myapp\__tests__\Link.test.js:2

^^^^^^

I'm using Node v7.5.0 and Webpack 2. I installed all the necessary dependencies and I also tried to sort with jest configuration, but it didn't sort my problem.

Can someone help me with this issue? Thanks!

State of the art webpack / React configuration

I'm trying to setup a webpack 2, babel, and React configuration for achieving:
Native ES6/ES7 features
Tree shaking builds
Hot reloading
I had a demo repo but it has distinct stuff mixed, like even JSHint and ESLint at the same time.
I'd like to get my setup up and running and get suggestions for best practices
So, as first option I tried to use babel-preset-env. Then after some dependencies being installed. I ran into this issue:
ERROR in ./src/main.jsx
Module build failed: SyntaxError: 'import' and 'export' may only appear at the top level (3:0)
However, the first line in my code is import 'babel-polyfill'; then just import's.
This is how my Babel config file looks like:
{
"presets": [
[
"env",
{
"modules": false,
"targets": {
"browsers": ["last 2 versions"]
}
}
],
"react"
],
"plugins": [
"babel-plugin-transform-class-properties",
"transform-react-require"
]
}
This is what my development webpack config file looks like:
const webpack = require('webpack');
const autoprefixer = require('autoprefixer');
const path = require('path');
const buildPath = path.resolve(__dirname, 'build');
const nodeModulesPath = path.resolve(__dirname, 'node_modules');
const TransferWebpackPlugin = require('transfer-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const config = {
//Entry points to the project
entry: [
'babel-polyfill',
'webpack/hot/dev-server',
'webpack/hot/only-dev-server',
path.join(__dirname, '../src/main.jsx')
],
//Config options on how to interpret requires imports
resolve: {
extensions: [".js", ".jsx"]
},
//Server Configuration options
devServer:{
contentBase: 'build', //Relative directory for base of server
devtool: 'eval',
hot: true, //Live-reload
inline: true,
port: 3000, //Port Number
host: 'localhost', //Change to '0.0.0.0' for external facing server
proxy: {
'^\/api': {
target: 'http://127.0.0.1:9090'
}
},
historyApiFallback: true
},
devtool: 'eval',
output: {
path: buildPath, //Path of output file
filename: 'app.js'
},
plugins: [
new webpack.DefinePlugin({
API_BASE: '""',
PRODUCTION: false,
'process.env.NODE_ENV': '"development"'
}),
//Enables Hot Modules Replacement
new webpack.HotModuleReplacementPlugin(),
//Allows error warnings but does not stop compiling. Will remove when eslint is added
new webpack.NoEmitOnErrorsPlugin(),
//Moves files
new TransferWebpackPlugin([
{from: 'www'}
], path.resolve(__dirname, "src")),
new ExtractTextPlugin("main.css")
],
module: {
rules: [
{
//React-hot loader and
test: /\.(js|jsx)$/, //All .js and .jsx files
loaders: [ 'babel-loader', 'react-hot-loader'],
//react-hot is like browser sync and babel loads jsx and es6-7
exclude: [nodeModulesPath]
},
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract({
fallback: 'style',
use: 'css'
})
},
{
test: /\.svg$/,
loader: 'svg-sprite?' + JSON.stringify({
name: '[name]_[hash]',
prefixize: true
})
}
]
}
};
module.exports = config;

I recently upgraded my boilerplate from webpack 1 to webpack 2, feel free to get any information / concept from the webpack config file there, hope it helps.
