In webpack 5.x, the compiler.hooks can not add any property into it.

So, when get the hardSourceCacheFactory property in tapable.hooks, it returns undefined:

@hzsrc What's the update?

[phillipuniverse]

@amerllica FYI I was able to remove this plugin completely in favor of native Webpack 5 filesystem caching.

This is what I added to my webpack.config.js to enable it:

    cache: {
      type: 'filesystem',
      buildDependencies: {
        config: [__filename]
      }
    },

On the first run of the dev server it populates the cache and takes ~1min, when I re-run it starts up in ~10s.

Also see #514 (comment)

@phillipuniverse, Thanks for your comment, my project is so big, very very big, so by using the native Webpack caching system, after the first time, I reduce the re-build time to 1min, I hope to find a way to reduce it below 300ms.

Finally, thanks.
