- Define State in Vuex Store:
- Create a Vuex store using
createStore
function. - Define the state object inside the store with the required properties.
// store/index.js
import { createStore } from 'vuex';
export const store = createStore({
state: {
// Define your state properties here
exampleProperty: null,
},
// Other store configurations...
});
- Mutations for State Mutation:
- Declare mutation functions to modify the state properties.
- Mutations must be synchronous and should not directly call API or perform asynchronous operations.
// store/index.js
export const store = createStore({
state: {
exampleProperty: null,
},
mutations: {
// Mutation to update exampleProperty
setExampleProperty(state, newValue) {
state.exampleProperty = newValue;
},
},
// Other store configurations...
});
- Actions for Asynchronous Operations:
- Create actions to handle asynchronous operations, API calls, or complex logic.
- Actions can commit mutations to modify the state.
// store/index.js
export const store = createStore({
state: {
exampleProperty: null,
},
mutations: {
setExampleProperty(state, newValue) {
state.exampleProperty = newValue;
},
},
actions: {
// Action to update exampleProperty asynchronously
async updateExampleProperty({ commit }, newValue) {
// Perform asynchronous operations or API calls
// Example: const response = await api.updateExampleProperty(newValue);
// Commit the mutation to update the state
commit('setExampleProperty', newValue);
},
},
// Other store configurations...
});
- Component Interaction:
- In a component, dispatch actions to update the state asynchronously.
// components/ExampleComponent.vue
export default {
methods: {
// Dispatch the action to update exampleProperty
async updateProperty(value) {
await this.$store.dispatch('updateExampleProperty', value);
},
},
};
- Getters for State Access:
- Define getters to retrieve state properties with possible transformations.
// store/index.js
export const store = createStore({
state: {
exampleProperty: null,
},
mutations: {
setExampleProperty(state, newValue) {
state.exampleProperty = newValue;
},
},
actions: {
async updateExampleProperty({ commit }, newValue) {
// Perform asynchronous operations or API calls
commit('setExampleProperty', newValue);
},
},
getters: {
// Getter to access exampleProperty
getExampleProperty: (state) => state.exampleProperty,
},
// Other store configurations...
});
- Component Access to State using Getters:
- In a component, use getters to access state properties.
// components/ExampleComponent.vue
export default {
computed: {
// Access exampleProperty through the getter
exampleProperty() {
return this.$store.getters.getExampleProperty;
},
},
};
- Strict Mode in Vuex:
- Enable strict mode in Vuex to catch mutations outside mutation handlers during development.
// store/index.js
export const store = createStore({
// Other store configurations...
strict: process.env.NODE_ENV !== 'production',
});
