Vuex - passing multiple parameters to mutation - vue.js

Question

I am trying to authenticate a user using vuejs and laravel's passport.I am not able to figure out how to send multiple parameters to the vuex mutation via an action.
- store -
export default new Vuex.Store({
state: {
isAuth: !!localStorage.getItem('token')
},
getters: {
isLoggedIn(state) {
return state.isAuth
}
},
mutations: {
authenticate(token, expiration) {
localStorage.setItem('token', token)
localStorage.setItem('expiration', expiration)
}
},
actions: {
authenticate: ({
commit
}, token, expiration) => commit('authenticate', token, expiration)
}
})
- login method -
login() {
var data = {
client_id: 2,
client_secret: '**************************',
grant_type: 'password',
username: this.email,
password: this.password
}
// send data
this.$http.post('oauth/token', data)
.then(response => {
// send the parameters to the action
this.$store.dispatch({
type: 'authenticate',
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
})
}
I would be very thankful for any kind of help!

Answer 1

Mutations expect two arguments: state and payload, where the current state of the store is passed by Vuex itself as the first argument and the second argument holds any parameters you need to pass.
The easiest way to pass a number of parameters is to destruct them:
mutations: {
authenticate(state, { token, expiration }) {
localStorage.setItem('token', token);
localStorage.setItem('expiration', expiration);
}
}
Then later on in your actions you can simply
store.commit('authenticate', {
token,
expiration,
});

In simple terms you need to build your payload into a key array
payload = {'key1': 'value1', 'key2': 'value2'}
Then send the payload directly to the action
this.$store.dispatch('yourAction', payload)
No change in your action
yourAction: ({commit}, payload) => {
commit('YOUR_MUTATION', payload )
},
In your mutation call the values with the key
'YOUR_MUTATION' (state, payload ){
state.state1 = payload.key1
state.state2 = payload.key2
},

Answer 3

i think this can be as simple
let as assume that you are going to pass multiple parameters to you action as you read up there actions accept only two parameters context and payload which is your data you want to pass in action so let take an example
Setting up Action
instead of
actions: {
authenticate: ({ commit }, token, expiration) => commit('authenticate', token, expiration)
}
do
actions: {
authenticate: ({ commit }, {token, expiration}) => commit('authenticate', token, expiration)
}
Calling (dispatching) Action
instead of
this.$store.dispatch({
type: 'authenticate',
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
do
this.$store.dispatch('authenticate',{
token: response.body.access_token,
expiration: response.body.expires_in + Date.now()
})
hope this gonna help
