When purifycss cleans up useless css, it causes a lot of useful css to be deleted.

want to add purifycss function, but after build, a lot of useful css have not been packaged?

I have the same problem


clipboard.png


glob.sync (path.join (SRC_PATH,' / .html')) the file directory here needs to contain all the places you use the style, and don't write it as index.html


I have the same problem.
tested

    new ExtractTextPlugin("css/index.css"), 
    new PurifyCSSPlugin({ 
      paths: glob.sync(path.join(__dirname, '../src/*.html')),
    }),
    
   

workaround:
1.new ExtractTextPlugin comes before new PurifyCSSPlugin.
2. Check to see if there is a problem with the'.. / src/*.html' path.


has the problem of landlord been solved? I also encountered the same problem. Ask for advice


if you encounter the same problem, the solution provided on the third floor can solve
new ExtractTextPlugin ({

.
filename: "css/[name].css?[hash:8]"

}),
new PurifyCSSPlugin ({

paths: glob.sync(path.join(__dirname, "../src/pages/*/*.html"))

})


Today, I also encountered the same problem. The answer upstairs gave me a lot of hints. In the end, I solved it like this:

const glob = require('glob-all');
plugins: [
    new ExtractTextPlugin({
          filename: "css/[name].css?[hash:8]"
        }),
    new PurifyCSSPlugin({
      paths: glob.sync([
        path.join(__dirname, '../index.html'),
        path.join(__dirname, '../src/*/*.jsx')
      ])
    })
]

solution:
1. You can only pass one string parameter to install glob.sync that comes with glob-all,.
1.new ExtractTextPlugin comes before new PurifyCSSPlugin.
2.glob.sync configure all files that you have referenced styles (note the path), such as html,jsx.
