how to avoid '.next/static/commons/main-xxxx.js' change???

next: 6.0.1-canary.2 just change a little code in page, the yarn build .next/static/commons/main-xxxx.js always change. How to avoid it? like this, modify some text in page/page2.js:

<div>Welcome to Page2 </div> to <div>Welcome to Page2 ABC </div>

the .next/static/commons/main-xxxx.js should not change when yarn build but the main-6974e8617b50c9d0b1bf.js changed to main-515736f6b9f5ff2e32e1.js

Does anyone know how to keep generated main-xxxx.js not change when dependent library has no change?

I already try to rewrite the next.config.js only process node_modules file, but no luck:

const path = require('path')

module.exports = {
  webpack: (config, { buildId, dev, isServer, defaultLoaders }) => {
    for (plugin of config.plugins) {
      if (plugin['constructor']['name'] === 'CommonsChunkPlugin') {
        plugin.minChunks = function (module, count) {
          var needChunk = (
            module.resource &&
            /\.js$/.test(module.resource) &&
            module.resource.indexOf(
              path.join(__dirname, './node_modules')
            ) === 0
          )
          if (needChunk) {
            console.log("needChunk = ", module.resource)
          }
          return needChunk
        }
        break;
      }
    }
    return config
  },
}

I wanna get like this .next/static/commons/main.js instead of .next/static/commons/main-xxxx.js how to operate ?

This won’t work with Next.js 7, and Next.js 7 implements records.json so hashes should be more stable now.
