CopyWebpackPlugin usage question

nobilik

Hi! Can’t copy robots.txt on quasar build with CopyWebpackPlugin. I’ve just copy-paste from there, but there is an error:

app:webpack Extending SPA Webpack config +493ms
(node:15489) UnhandledPromiseRejectionWarning:   ValidationError: Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
   - options[0] misses the property 'patterns'. Should be:
     [non-empty string | object { from, to?, context?, globOptions?, toType?, force?, flatten?, transform?, cacheTransform?, transformPath?, noErrorOnMissing? }, ...] (should not have fewer than 1 item)

What I’m doing wrong? Help pls!

Hi,
Did you find the solution?
I have the same problem and I still managed to find the solution.
Thank you in advance.

This might be because you’ve updated to a newer version. What solved it for me was changing from:

    const CleanWebpackPlugin = require('clean-webpack-plugin');

    ...
    
    plugins: [
        new CleanWebpackPlugin(),
        new MiniCssExtractPlugin({
            filename: "css/[name].bundle.css",
            chunkFilename: "css/[name][id].bundle.css"
        }),
        new CopyWebpackPlugin([{
            from: path.resolve(__dirname, '../src/static')
        }])
    ],

to:
    const { CleanWebpackPlugin } = require('clean-webpack-plugin');

    ...

    plugins: [
        new CopyWebpackPlugin({
            patterns: [
                {from: path.resolve(__dirname, '../src/static')}
            ]
        })
    ],

install robotstxt-webpack-plugin.js

npm i robotstxt-webpack-plugin
in your quasar.conf.js
import

 const RobotstxtPlugin = require("robotstxt-webpack-plugin");
const options = {
  filePath: "/robots.txt",
  policy: [
    {
      userAgent: "*",
      Allow: 'All',
      crawlDelay: 30
    }

  build: {
      scopeHoisting: true,
      vueRouterMode: "history", // available values: 'hash', 'history'
      showProgress: true,
      gzip: false,
      analyze: false,
      // Options below are automatically set depending on the env, set them if you want to override
      // preloadChunks: false,
      extractCSS: true,

      // https://quasar.dev/quasar-cli/cli-documentation/handling-webpack
      extendWebpack(cfg) {
        cfg.plugins.push(
          new RobotstxtPlugin(options)
