For building a lib i want to disable codeSplitting with webpack

adding the LimitChunkCountPlugin

   plugins: [
    new webpack.optimize.LimitChunkCountPlugin({
      maxChunks: 1,
    }),
  ],

but get this error on build

When you have native support for Web Workers, you always have more than 1 chunk… You can try:

new webpack.optimize.LimitChunkCountPlugin({
      maxChunks: 2,
}),

@alexander-akait For me, the error started popping up after I removed worker-loader in favor of Webpack 5’s native support for Web Workers. I am sure it’s caused due to LimitChunkCountPlugin because disabling it causes builds to pass.
