Vue.js: Nuxt error handling

Question

Struggling a bit to set up error handling with vuex. There seems to be quite a few ways to do so and little documentation on proper error handling. I\'ve been experimenting with

Answer 1

Create an error key in the state of each Vuex module. Then dispatch the error for a given component to its relative Vuex module. Then create a global handler to watch for errors in the separate Vuex modules and, if one is triggered, display the error.

// store/auth.js

export const state = () => {
  return {
    success: null,
    error: null
  }
}

export const actions = {
  async login({ commit }, { email, password }) {
    try {
      const response = await axios.post('/api/login', {
        email,
        password
      })
      commit('SET_SUCCESS', response)
    } catch(err) {
      commit('SET_ERROR', error)
    }
  }
}

export const mutations = {
  SET_SUCCESS(state, payload) {
    state.success = payload
  },
  SET_ERROR(state, payload) {
    state.error = payload
  }
}

// auth.vue

export default {
  methods: {
    onLogin() {
      try {
        await this.$store.dispatch('auth/login', {
          email: this.email,
          password: this.password
        })
        if (this.$store.state.auth.success) this.$router.push('/home')
      } catch (err) {
        console.log(err)
      }
    }
  }
}

// app.vue

export default {
  created() {
    this.$store.subscribe((mutation, state) => {
      if (mutation.type.includes('ERROR')) {
        // display error in global error output
        console.log(mutation.payload)
      }
    })
  }
}
