There are several ways to share data between components in Vue.js:

  1. Props: You can pass data from a parent component to a child component using props. In the parent component, you define the data and pass it as props to the child component. In the child component, you can access and use the data passed through the props. Example: // ParentComponent.vue // ChildComponent.vue
  2. Events: You can emit events from a child component to notify the parent component about a change in data. In the child component, you define a method that emits an event with the updated data. In the parent component, you listen for the event and update the data accordingly. Example: // ChildComponent.vue // ParentComponent.vue
  3. Vuex: Vuex is a state management pattern and library for Vue.js applications. It allows you to centralize the data in a store that can be accessed by any component. Components can read and update the data in the store using mutations and actions. Example: // store.js import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) export default new Vuex.Store({ state: { data: 'Hello World' }, mutations: { updateData(state, newData) { state.data = newData } }, actions: { updateData(context, newData) { context.commit('updateData', newData) } }, getters: { getData(state) { return state.data } } }) // ChildComponent.vue // ParentComponent.vue


These are some of the common ways to share data between components in Vue.js. The choice of method depends on the specific use case and complexity of the application.
