I don't see any cons to using strict mode with this vuex. The performances seem better and it is easier to debug. So, why disable that mode?

CodePudding user response：

Strict mode should not be used in production. Strict mode runs a synchronous deep watcher on the state tree for detecting inappropriate mutations, and this can slow down the application. To avoid changing strict to false each time you want to create a production bundle, you should use a build tool that makes the strict value false when creating the production bundle

you can enable that mode with this:

const store = new Vuex.Store({  // ...  strict: true});
