One issue I'm facing is the challenge of reactively adding data to either the Vue root or a Vue component. After mounting my Vue app instance using app.mount(), I find it difficult to dynamically add data to the application. As someone new to the framework, I am trying to integrate Vue with vanilla JS. Essentially, I'm wondering if there's an event or object in vanilla JS that can be triggered to insert new data, such as into an array of objects within the Vue app instance.
The most straightforward approach is to integrate Vuex into your Vue 3 application and pass data through the Vuex store.
If you want to create a basic Vue 3 project using vue-cli, you can run the command vue create my-vue-prj
{
"name": "my-vue-prj",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",
"lint": "vue-cli-service lint"
},
"dependencies": {
"core-js": "^3.6.5",
"vue": "^3.0.0",
"vuex": "^4.0.0-0"
},
"devDependencies": {
...((skipped))...
}
}
Additionally, here is the entry point in src/main.js.
import { createApp } from "vue";
import App from "./App.vue";
import store from "./store";
const app = createApp(App);
app.use(store).mount("#app");
window.vueApp = app;
// Alternatively, you can also expose the store directly
// window.store = store;
You can access the Vuex store like this.
// external.js
const store = window.vueApp.config.globalProperties.$store
/*
* You can manipulate data in the Vue app through `store`
*/
A predefined array is stored in the Vuex store as shown below:
// file : src/store/index.js
import { createStore } from "vuex";
export default createStore({
state: {
nums: [0, 1, 2],
},
mutations: {
replaceNum(state, nums) {
state.nums = nums;
},
},
actions: {},
modules: {},
});
nums needs to be displayed in App.vueYou can access the array nums from the component App.vue.
<template>
<img alt="Vue logo" src="./assets/logo.png" />
<ul>
<li v-for="(n, index) in $store.state.nums" :key="index">{{ n }}</li>
</ul>
</template>
$store.state.nums represents the array of [0, 1, 2]The array nums can be updated externally using the following script:
// external.js
const store = window.vueApp.config.globalProperties.$store
store.commit('replaceNum', [2, 3, 5, 7, 11]);
commit('replaceNum', ...) - This triggers the replaceNum method in mutations, updating the nums array and refreshing the contents as well.I am currently working on a website and I am looking to create an effect where an image is masked by an overlay.
