I have a webpack.config.js that scans a config folder to build different bundles in different output folders so that each of those output folders can be a standalone website. For each of those output folders, I want to inject the folder’s contenthash’d bundle into src/template.html to yield an index.html written to each output folder.

The official webpack docs recommend HtmlWebpackPlugin when one wants to use an html template, but when I try (using v5.6.0 of the plugin)…

plugins: [
    new HtmlWebpackPlugin({
        filename:  '[name]index.html'
        ,template:  './src/template.html'
    })
]

…it injects all the bundles from all my output folders into each index.html.

I have looked through the github page of the plugin, and the source of its index.js, but I cannot find a way to limit each index.html’s bundle to just the one in the same output folder.

I can’t use the chunks property unless it can take a value like [contenthash].js
The documentation mentions only fully-specified values, not placeholders.
