Vue 3 is the latest version of the easy to use Vue JavaScript framework that lets us create front end apps.

In this article, we’ll look at how to create a to-do list app with Vue 3 and JavaScript.

Create the Project

We can create the Vue project with Vue CLI.

To install it, we run:

npm install -g @vue/cli

with NPM or:

yarn global add @vue/cli

with Yarn.

Then we run:

vue create grocery-list

and select all the default options to create the project.

We also need the uuid package to let us generate unique IDs for our grocery list items.

To do this, we run:

npm i uuid

Create the Grocery List App

To create the grocery list app, we write:

    <form @submit.prevent="add">
        <input v-model="item" />
      <button type="submit">add item</button>

    <div v-for="(item, index) of items" :key="">
      {{ item.item }}
      <button @click="remove(index)">remove</button>

import { v4 as uuidv4 } from "uuid";
export default {
  name: "App",
  data() {
    return {
      item: "",
      items: [],
  methods: {
    add() {
      const { item } = this;
        id: uuidv4(),
    remove(index) {
      this.items.splice(index, 1);

We have the form element with the @submit directive to let us listen to submit events, which is triggered when we click add item.

v-model is bound to item so that we can get the entered value from the add method.

With the v-for directive, we render the added items.

The key is required to be a unique ID, so that Vue 3 can keep track of the items in the rendered list.

We have the remove button to remove the item.

In the component object, we have the data method to define the item we want to add.

items have the items we added.

In add , we call this.items.push to add an item to the grocery list.

We generate a unique ID for each item with the uuidv4 function.

In the remove method, we call this.items.splice to remove an item by its index.

Now we can add and remove items from the grocery with the add item button and remove button respectively.


We can write a grocery list app easily with Vue 3 and JavaScript.
