打包去除console

babel.config.js

+// module.exports = {
+//   presets: ["@vue/cli-plugin-babel/preset"]
+// };
+let plugins = [];
+if (process.env.NODE_ENV === "production") {    // todo  if判断是否打包,打包环境下控制台去掉console.log,也可去掉if判断，整个项目不会出现console.log(不建议)
+  plugins.push("transform-remove-console");
+}
 module.exports = {
-  presets: ["@vue/cli-plugin-babel/preset"]
+  presets: ["@vue/cli-plugin-babel/preset"],
+  plugins: plugins

+  // plugins: ["@babel/plugin-proposal-optional-chaining"]
