How to call an action from within another action in Vuex?

Question

I have the following setup for my actions:

get1: ({commit}) => {
  //things
  this.get2(); //this is my question!
},
get2: ({commit}) => {
  //things
},

I want to be able to call one action from within another, so in this example I want to be able to call get2() from within get1(). Is this possible, and if so, how can I do it?

Answer 1

You have access to the dispatch method in the object passed in the first parameter:

get1: ({ commit, dispatch }) => {
  dispatch('get2');
},

This is covered in the documentation.

Is there a way to do something once an action is complete? Basically use this with a then()? – Hagioscope

Yep, it's fully covered in the documentation page I linked – Charley

How can I dispatch an action from another store? e.g. in store A I want to do dispatch('B/someaction') – Mons

Answer 2

You can access the dispatch method through the first argument (context):

export const actions = {
  get({ commit, dispatch }) {
    dispatch('action2')
  }
}

However, if you use namespaced you need to specify an option:

export const actions = {
  get({ commit, dispatch }) {
    dispatch('action2', {}, { root: true })
  }
}

for actions that does not require payload

actions: {
    BEFORE: async (context, payload) => {
    },
    AFTER: async (context, payload) => {
        await context.dispatch('BEFORE');
    }
}

for actions that does require payload

actions: {
    BEFORE: async (context, payload) => {
    },
    AFTER: async (context, payload) => {
        var payload = {}//prepare payload
        await context.dispatch('BEFORE', payload);
    }
}

we can pass parameters also while dispatching.

dispatch('fetchContacts', user.uid);

export actions = {
  GET_DATA (context) {
     // do stuff
     context.dispatch('GET_MORE_DATA');
  },

  GET_MORE_DATA (context) {
    // do more stuff
  }
}
