I have a problem when i updated in my project the webpack package to V5.x.
Here is the error :

I tried a lot of things and i fixed a lot of issues but for me the entry is an Array, so i don't know why i got this error.
Here there is my server.js (he launches all the programs) :

}

app.use(router.routes()).use(router.allowedMethods())
if (c.port) {
app.listen(c.port, c.host, err => {
const url = `http://${c.host}:${c.port}`
if (err) console.error(chalk.red(`\n==> Error happen ${err}`))
console.info(chalk.green(`\n==> 🌎 Listening at ${url}`))
})
} else {
console.error(chalk.red('\n==> Error : No PORT environment variable has been specified'))
}
}
)
UPDATE :
I put some console.log in the compiler file :
for (const key of Object.keys(entry)) {
const value = entry[key];
console.log(entry)
console.log(value)
console.log(Array.isArray(Object.values(value)))
if (!Array.isArray(value)) {
throw new TypeError(
'webpack-hot-client: `entry` Object values must be an Array or Function. Please check your webpack config.'
);
Console.log return this :
main: { import: [ 'webpack-hot-middleware/client', './src/index.js' ] }
}
{ import: [ 'webpack-hot-middleware/client', './src/index.js' ] }
true
So i think that there is a problem with the declaration of variable, because we have to do an Object.values() to get the array.
So idk what can i do to resolve the problem, i will not change the dependencies files...
Thx for your time and your response!

It might not be the right example to your situation, but they made some internal changes to the webpack structure:
entry: {} allows an empty object now (to allow to use plugins to add entries)
here's one of the newer examples I found:
module.exports = {
entry: {
about: { import: './about.js', filename: 'pages/[name][ext]' },
},
};
Source: Webpack v5 internal changes: Entry
I found the error. WebPack Hot Client is not update for the last version of webpack (5.x). If you use Webpack Hot Client, you have to use version 4 of Webpack.

What is the problem with my project? I receive an empty page after successful deployment to vercel.

I've got a react app (latest React version) with a NodeJS backend.
That runs so far locally. But now I want to use this React App (together with its NodeJS backend) with other devices in my home network.
How to do that?
That is my package.json of the React App:

What I tried so far:
Commented in host: '0.0.0.0' in the webpack.config.js
Added the line: "dev": "webpack-dev-server --hot --env.mode=development --host 0.0.0.0", to scripts attribute in the package.json
Removed --hot parameter in the scripts attribute of "dev" command
Can someone help here?
try to add HOST=0.0.0.0 to script object

I've been using React 16.x.x and Jqwidgets 6.2.0 and React Boilerplate 3.7.0. My whole project was mounted over the React Boilerplate scaffold with its own configuration of webpack. I set jqwigets-scripts as a npm dependency and I tried excluding node_modules but including jqwidgets-scripts/jqwidgets-react through a regular expression as I read in some github. This is my current webpack.base.babel.js file:
...
module: {
rules: [
{
test: /\.js$/, // Transform all .js files required somewhere with Babel
exclude: /node_modules\/(?!(jqwidgets-scripts\/jqwidgets-react)\/).*/,
use: {
loader: 'babel-loader',
options: options.babelQuery,
},
},
...
With this configuration webpack compiles with no warnings and no errors like a charm, that is to say npm start. The big deal comes out to stage if I say npm run-script build, if so it complains with this:
Hash: 7b0feef0f8bbac0c9421

You may need an appropriate loader to handle this file type.

I tried changing my webpack configuration as recommended in the official jqwidgets page (https://www.jqwidgets.com/community/topic/webpack-module-parse-failed/) like this:
module: {
rules: [
{
test: /\.js$/,
exclude: '/node_modules',
include: '/node_modules/jqwidgets-scripts/jqwidgets-react',
use: {
loader: 'babel-loader',
options: options.babelQuery
}
},
Then the complain is this while running npm start:
webpack built be60767d46a99fe48e6b in 1353ms
✖ ｢wdm｣:
ERROR in ./app/app.js 80:4
Module parse failed: Unexpected token (80:4)
You may need an appropriate loader to handle this file type.

My question is, how to configure webpack in order to work properly in production mode?
I’m having below issue when running build function using web pack, can you please have a look? npm build、 delete node_modules、update node.js version. Please help me.

You may need an appropriate loader to handle this file type.

Running this command node_modules\.bin\webpack --config webpack.config.js --mode development it should be able to work but it doesn't.
These are specifications:
node: v8.11.2
webpack 4.17.2
vuejs 2.5.17
Anything else you want to know, please tell me.
For anyone else that runs into this issue, newer versions of vue-loader need to be loaded in the webpack plugins section:
// Required for vue-loader v15
const VueLoaderPlugin = require('vue-loader/lib/plugin')
environment.plugins.append(
'VueLoaderPlugin',
new VueLoaderPlugin()
)
From https://github.com/rails/webpacker/issues/1453#issuecomment-412291197
It looks like you don’t have a rule configured for .vue files: you have one for .vue.html files but not for just .vue files. You can just change your existing rule by removing the \.html in order to make it work.
