Create a Dice Game with Vue 3 and JavaScript

Spread the love

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 dice game 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 dice-game

and select all the default options to create the project.

Create the Dice Game

To create the dice game, we write:

<template>
  <div>
    <button @click="roll">roll</button>
    <p>rolled dice value: {{ rolledValue }}</p>
  </div>
</template>

<script>
export default {
  name: "App",
  data() {
    return {
      rolledValue: 1,
    };
  },
  methods: {
    roll() {
      this.rolledValue = Math.ceil(Math.random() * 5 + 1);
    },
  },
};
</script>

We have the roll button that calls roll when we click on it.

The rolledValue is displayed below it.

In the script tag, we have the data method that returns an object with the rolledValue reactive property.

The roll method sets the rolledValue to a random number between 1 and 6.

Math.random returns a number between 0 and 1, so we’ve to multiply the returned value by 5 and add 1 to get a value between 1 and 6.

Math.ceil returns a number rounded up to the nearest integer.

Conclusion

We can create a dice game easily with Vue 3 and JavaScript.
