Discussion on: Architecting Vuex store for large-scale Vue.js applications

I understand that, we shouldn't mutate state outside of mutations. But mutating is one thing and reading is different. What I am concerned with is reading. I can directly read store object from this.$store.state, so why do you think it is a good practice to use getters?

It is totally fine to use this.$store.state, or mapState to map the state properties into a component. But, considering the chances that these might get referenced or mutated, we can take a safe stand. Using getters too much is also a problem since they are actually computed properties for your store they need a bit of extra computation. The pro side of using getters is that we can move more of the logic, (if any involved in processing the state properties) inside your getters and have a safe stand on preventing it from getting mutated.
