Javascript error at project launch


Topic: Javascript error at project launch

Kiril pro premium priority asked 2 years ago

Hi, We just purchased MDB pro and we've installed it with NPM with our token.

We're trying to install it with a sample ASP.NET Core 2.2 project with Visual Studio 2019. We use WebPack 4. When we run the project we get the following error message: Cannot assign to read only property 'exports' of object '#'

This is the webpack.config

const path = require('path'); const { CleanWebpackPlugin } = require('clean-webpack-plugin'); const CopyWebpackPlugin = require('copy-webpack-plugin'); const HtmlWebpackPlugin = require('html-webpack-plugin'); const MiniCssExtractPlugin = require('mini-css-extract-plugin'); var webpack = require('webpack');

module.exports = {

entry: [
    './wwwroot/src/js/ImportModule.js',
    './wwwroot/src/js/App.js',
    './wwwroot/src/less/Vendors.css',
    './wwwroot/src/less/Site.less'

],
plugins: [


    new MiniCssExtractPlugin({
        filename: "css/site.css"
    }),
    new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery"
    }),
    new CopyWebpackPlugin([
        {
            from: '**/*',
            to: 'mdb-addons',
            context: path.resolve(__dirname, 'src', 'lib', 'mdb', 'mdb-addons'),
        },
    ])

        },

    ]

Hi. I'll check this. Give me some time. I have more case witch similar issues and others technology, so i try create universal basic webpack config for all


lemons commented 2 years ago

I do have the same issue with Laravel webpack mixins. Currently I simply bundled all minified JS files by hand, as they don't change anyhow, and excluded JS from webpack mixins.


Grzegorz Bujański staff commented 2 years ago

Probably I was create proper config for webpack yesterday. But I need some more time to work out the details and test this. I hope that soon I will be able to send the correct configuration. At this moment i can tell you i use this babel config:


{
  "presets": [
    [
      "@babel/preset-env",
      {
        "useBuiltIns": "usage",
        "corejs": "3.0.0"
      }
    ]
  ],
  "plugins": [
    "@babel/plugin-syntax-dynamic-import",
    "@babel/plugin-proposal-class-properties"
  ]
}

@Kiril can you test this in your project?


Kiril pro premium priority commented 2 years ago

Still the same.


Grzegorz Bujański staff commented 2 years ago

Ok. So I'm going back to work on this


Kiril pro premium priority commented 2 years ago

Any news on this, I really need to package this with WebPack! I can't use the library at all. Very pricey for something I can't use!!


Grzegorz Bujański staff commented 2 years ago

Hi. Sorry about that. I almost done. Problem should be fixed in next relese.


Kiril pro premium priority commented 2 years ago

Great news! Thanks for the follow up.


Kiril pro premium priority commented 2 years ago

Any progress on that issue?


Grzegorz Bujański staff commented 2 years ago

There was a problem with two libraries during testing. We try solve this problem.
