Error [ERR_REQUIRE_ESM]: require() of ES Module inside quasar-app-extension-ssg's server-entry.js about quasar-app-extension-ssg

[freddy38510]

When running quasar build -m ssr or quasar ssg generate command, it compiles both client-side and server-side outputs. The server-side compiled code is in CommonJs format.

The query-string package is a pure ESM since its version 8.0.0.

So you need to transpile this library to commonJs. To do this, try adding this to your quasar.config.js file:

// quasar.config file

build: {
  extendViteConf (viteConf, { isServer }) {
    if(isServer) {
       // see https://v2.vitejs.dev/config/#ssr-noexternal

       viteConf.ssr = viteConf.ssr || { };
       viteConf.ssr.noExternal = viteConf.ssr.noExternal || [];
       viteConf.ssr.noExternal.push('query-string');

      // if it doesn't work, try this instead:
      // viteConf.ssr.noExternal.push(/query-string/);
    }
  }
}
