Testing repo https://github.com/edwardfhsiao/prerender-loader-test-repo

$ npm i
$ npm run compile

template: `!!prerender-loader?string!${PATH.HTML_PATH}/template.html` locates in production.config.js file

I'm wondering if removing the cache inheritance would fix this:
https://github.com/GoogleChromeLabs/prerender-loader/blob/master/src/index.js#L131-L143 nope

I think I found the issue, I was using os.tmpdir(), but had meant to use fs.mkdtempSync().

@edwardfhsiao alright, I figured out the issue with the demo you linked above: it's a duplicate of #25, and the solution I posted there a couple hours ago works here too:

Object.keys(config.entry).map(i => {
  config.plugins.push(
    new HtmlWebpackPlugin({
-     template: `!!prerender-loader?string!${PATH.HTML_PATH}/template.html`,
+     template: `!!prerender-loader?string&entry=${config.entry[i]}!${PATH.HTML_PATH}/template.html`,
      // etc
    }),
  );
});

@developit Awesome, that solved my problem. Really appreciate your help!

This issue may have to be looked at again. The error still occurs if using the {{prerender}} in the template tag as specified in the docs:
https://github.com/GoogleChromeLabs/prerender-loader#injecting-content-into-the-html

I spent many hours trying to debug our config and was still getting the multiple chunks error until i realized this.

To replicate, replace the template.html file in the example repo (https://github.com/edwardfhsiao/prerender-loader-test-repo) with:

<div id="root">{{prerender}}</div>

and run npm run compile or yarn compile.

It's not clear where the <%= htmlWebpackPlugin.options.title %> formatting comes from, but using {{prerender}} in the template as specified in the docs fails with multiple entry files.

I can open a new issue if needed.

@northamerican <%= htmlWebpackPlugin.options.title %>just comes from

 new HtmlWebpackPlugin({
      ...
      title: `${i}`,

It is a format of HtmlWebpackPlugin, which does not really matter in this case.

As for the multiple entry issues, I guess still needs @developit 's help.
