webpack module federation and single-spa-vue with vue 2.16.12 not working

I'm developing a microfront with single-spa-vue and Vue 2.6.12 and it's not working at all.
I'm using webpack module federation plugin.
This is my entry point.
src/app.ts
import singleSpaVue from 'single-spa-vue';
import Vue from 'vue';
import Main from './Main.vue';
import router from './router';
const lifecycles = singleSpaVue({
Vue,
appOptions: {
render(h: any) {
return h(Main as any);
},
router,
} as any,
});
export const bootstrap = lifecycles.bootstrap;
export const mount = lifecycles.mount;
export const unmount = lifecycles.unmount;
This is my webpack.config.js file
const ModuleFederationPlugin = require('webpack/lib/container/ModuleFederationPlugin')
const StandaloneSingleSpaPlugin = require('standalone-single-spa-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { VueLoaderPlugin } = require('vue-loader')
const path = require('path');
const outputPath = path.resolve(__dirname, 'dist');

}
And this is my index.ts file
src/index.ts
import { start, registerApplication } from 'single-spa'
registerApplication({
name: 'content',
app: () => import('content/Content' as any),
activeWhen: '/',
},)
start()
And when I run yarn start and go to localhost:3002 this is the error.

Does anyone can help me plz?
Thanks!

Well，may be u mixing the relationship with the host container and remote container, I saw your ModuleFederationPlugin config that special remotes and name is same, it seen like not correct.

copy-webpack-plugin doesn't copy files

I try to just copy files to check simple webpack config. So I stuck trying to make copy-webpack-plugin to work - nothing happens: no copied files, no errors, nothing
Common config (webpack.common.js):
const path = require('path');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const postCssPlugin = [
require('postcss-import'),
require('postcss-nested'),
require('postcss-simple-vars'),
require('autoprefixer')({
browsers: [
'last 3 versions',
'android 4.2'
]
})
];
module.exports = {
context: path.resolve(__dirname, '../src'),
entry: [
'babel-polyfill',
path.resolve(__dirname, '../src/index.js')
],
output: {
path: path.resolve(__dirname, '../dist/js'),
publicPath: '',
filename: 'app.js'
},
resolve: {
extensions: ['.jsx', '.js', '.json']
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.p?css$/,
use: [
'style-loader',
'css-loader',
{
loader: 'postcss-loader',
options: {
ident: 'postcss',
plugins: postCssPlugin
}
}
]
}
]
},
plugins: [
new CopyWebpackPlugin([
{
from: path.resolve(__dirname, '../src/assets/**/*'),
to: path.resolve(__dirname, '../dist/assets'),
flatten: true
}
])
],
stats: {
modules: true,
warnings: false,
version: true,
timings: true,
performance: false,
hash: true,
errors: true,
errorDetails: true,
colors: true,
builtAt: true
}
};
webpack.prod.js:
const commonWebpackConfig = require('./webpack.common.js');
const UglifyJsWebpackPlugin = require('uglifyjs-webpack-plugin');
module.exports = Object.assign(commonWebpackConfig, {
mode: 'production',
plugins: [
new UglifyJsWebpackPlugin({
sourceMap: true
})
]
});
And build starting file build.js:
const webpack = require('webpack');
const webpackProdConfig = require('./webpack.config/webpack.prod.js');
webpack(webpackProdConfig, (err, stats) => {
if (err || stats.hasErrors()) {
console.error(err.stack || err);
}
console.log('Successfully compiled!');
});
So could anyone figure out why doesn't it work and where am I wrong?
copy-webpack-plugin: 4.5.2
node: 9.1.0
npm: 6.3.0
windows: 10
Addition - folder structure:

Try to copy from the dist folder. For me it worked
es.
new CopywebpackPlugin([{
from: path.resolve(__dirname, 'node_modules/mettrr-component-library/dist/img'),
to: path.resolve(__dirname, 'src/assets/img')
}]),

How to work with fonts and icons in webpack?

I needed to create webpack config for project where I use reactjs,semantic-ui-react and nucleo icons. It build almost everything except fonts and icons. I don't quite understand how to build them and nucleo icons dont display in project after build.My config:
const path = require('path');
const webpack = require('webpack');
const autoprefixer = require('autoprefixer');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const ASSETS_PATH = './assets';
const BUILD_DIR = path.resolve(__dirname, 'build');
var webpack_config = {
context: path.resolve(__dirname, ASSETS_PATH),
entry: {
main : [
"react",
"react-dom",
"react-props",
"redux",
"react-redux",
"redux-thunk"
],
module : "./js/module/index.jsx",
},
output: {
filename: '[name].min.js',
path: BUILD_DIR + '/js'
},
resolve: {
extensions: [' ','.js', '.jsx', 'css']
},
devtool: 'inline-source-map',
module : {
loaders : [
{
test : /\.jsx?/,
loader : 'babel-loader?compact=true&comments=true&minified=true',
query: {
presets:[
'es2015',
'react',
'stage-1'
]
},
exclude: /node_modules/
},
{
test: /\.(woff|woff2|eot|ttf|svg)(\?.*)?$/,
loader: 'file-loader?name=../css/fonts/[name].[ext]',
options: {
limit: 10000
}
},
{
test: /\.(png|jpe?g|gif)(\?.*)?$/,
loader: 'file-loader?name=../css/images/[name].[ext]'
},
{
test: /\.json$/,
loader: "json-loader"
},
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
fallback: "style-loader",
use: "css-loader"
})
}
]
},
plugins: [
new webpack.DefinePlugin({
"process.env": {
NODE_ENV: JSON.stringify(process.env.NODE_ENV || 'production')
}
}),
new ExtractTextPlugin({
filename: "../css/style.min.css",
disable: false,
allChunks: true
}),
new OptimizeCssAssetsPlugin({
assetNameRegExp: /\.min\.css$/g,
cssProcessor: require('cssnano'),
cssProcessorOptions: { discardComments: { removeAll: true } },
canPrint: true
}),
new webpack.optimize.CommonsChunkPlugin({
names: ["main"]
}),
new webpack.optimize.UglifyJsPlugin({
minimize : true,
sourceMap : false,
beautify : false,
comments : false,
compress: {
warnings: false
}
})
]
};
module.exports = webpack_config;
So as a result I get js bundles in map 'js', I get css bundle style.min.css in css map. There also webpack creates images map, and puts jpg,png,svg. But font files(eot,ttf etc) he puts in js map with long names. How should I refactor my config in order to solve this problem?

Solved this problem with such loader structure(maybe will be usefull for somebody):
{
test: /\.(eot|svg|ttf|woff|woff2?)$/,
use: {
loader: 'file-loader'
, options: {
name: '../css/fonts/[name]-[hash:8].[ext]'
}
}
},

Thanks for your interest towards Syncfusion controls.
We recommend you to configure aurelia-syncfusion-bridge resources in webpack.config.js file. Because aurelia-syncfusion-bridge’s resources are traced by aurelia-webpack-plugin and included in app.bundle.
Suppose If we add this plugin in webpack.vendor.js, we need to bundle manually for every additional aurelia-syncfusion-bridge’s resources for proper bundling. Since, we recommend to configure our bridge in webpack.config.js, which will automatically bundle the bridge source along with application bundle.
We have prepared sample for the same and attached below.
Sample
Please let us know if you need further assistance on this.

Vue js in cordova

I'm struggling to implement a simple Vue.js app into Cordova. Everything works fine except that I don't know how I can intercept cordova events (deviceready, pause, ...) into my vue application. I used the Webpack template from vue-cli.
Here's my file js/index.js :
const app = {
initialize: function () {
console.log('initialize')
this.bindEvents()
},
bindEvents: function () {
document.addEventListener('deviceready', this.onDeviceReady, false)
},
onDeviceReady: function () {
app.receivedEvent('deviceready')
},
receivedEvent: function (id) {
console.log('Received Event: ' + id)
}
}
app.initialize()
the src/main.js :
import Vue from 'vue'
import App from './App'
/* eslint-disable no-new */
const app = new Vue({
template: '<App/>',
components: { App }

app.$mount('#app')

What shoud I do to get events from Cordova to my Vue components ?

See this article, it worked for me:
https://coligo.io/building-a-mobile-app-with-cordova-vuejs/
To allow the app to access the Vue.js library, we also need to add the following to the end of the Content Security Policy (CSP) meta tag in www/index.html:
; script-src 'self' http://cdn.jsdelivr.net/vue/1.0.16/vue.js 'unsafe-eval'

Looks like the issue was that Cordova.js is not included in browser, you need to test on a physical device.
That doesn't mean you can't prototype in the browser though. In JS, window.cordova will be defined if cordova has loaded. So you can setup your initialization like so
if(window.cordova){
//add deviceready event to start app
} else {
//call starting function
}
For things requiring a physical device: vibration, accelerometer, etc, you have to build and deploy to a device, the browser itself is not enough.
