How to correctly add `'@': resolve ('src') `?

in webpack.base.config.js , why do I add "@": resolve ("src") in resolve -> alias npm run dev ?

...
resolve: {
    extensions: [".js", ".vue"],
    alias: {
      "vue": "vue/dist/vue.esm.js",
      //"@": resolve("src")
    }
  }
  

does this take effect after I install something or configure something?
