Learn how you can make a Vue application using Vue CLI.

Getting Started

Before we start creating the application, you will need a few things.

  1. Have Node.js installed
  2. Have @vue/cli installed

Installing @vue/cli

The Vue CLI is used to create new Vue applications and to easily add plugins to your application.

terminal
# Using NPM
npm install -g @vue/cli
# Using Yarn
yarn global add @vue/cli

After installation, you will have access to the vue command in your command line. You can verify that it is properly installed by running vue, which should show you a help message listing all available commands.

You can check that you have the right version installed by running this command:

terminal
vue --version

Upgrading @vue/cli

To upgrade the global Vue CLI package, you can run this command:

terminal
# Using NPM
npm update -g @vue/cli
# Using Yarn
yarn global upgrade --latest @vue/cli

You can read more about how to use the Vue CLI on their website.

Creating the Vue Application

We will start by running the following command:

terminal
vue create my-vue-app

Preset

It will now prompt you with a few questions:

terminal
Vue CLI v4.5.13
? Please pick a preset: (Use arrow keys)
> Default ([Vue 2] babel, eslint)
  Default (Vue 3) ([Vue 3] babel, eslint)
  Manually select features
  • Default ([Vue 2] babel, eslint) is a default preset for Vue 2.
  • Default (Vue 3) ([Vue 3] babel, eslint) is a default preset for Vue 3.
  • Manually select features choosing this option, you can (as it says) manually select the features you want.

I prefer to pick the Manually select features option.

Features

Next, it will ask you with features you want to add to your project:

terminal
Vue CLI v4.5.13
? Please pick a preset: Manually select features
? Check the features needed for your project: (Press <space> to select, <a> to toggle all, <i> to invert selection)
> (*) Choose Vue Version
  (*) Babel
  ( ) TypeScript
  ( ) Progressive Web App (PWA) Support
  ( ) Router
  ( ) Vuex
  ( ) CSS Pre-processors
  (*) Linter / Formatter
  ( ) Unit Testing
  ( ) E2E Testing

I'll go over what each of these options means.

  • Choose Vue Version basically means that you can decide which version of Vue you want to use. You can pick either Vue 2 or Vue 3.
  • Babel adds babel to the project.
  • TypeScript adds TypeScript support to the project.
  • Progressive Web App (PWA) Support makes it possible for you to make your web app a PWA.
  • Router adds vue-router to the project.
  • Vuex adds vuex to the project, this is used for state management.
  • CSS Pre-processors this allows you to choose which CSS Pre-processor you want to use (SASS, LESS, etc...).
  • Linter/Formatter allows you to choose which linter and/or formatter you want to use.
  • Unit Testing adds Unit Testing to the project.
  • E2E Testing adds E2E Testing to the project.

Most of the time I pick the following:

  • Choose Vue Version > Vue 2 or Vue 3, depends on which version I need
  • Babel
  • TypeScript
  • Router — I only ever pick this if I need routing
  • Vuex
  • CSS Pre-processors > SASS/SCSS
  • Linter/Formatter > ESLint with error prevention only

After you've picked the features that you'll want it will ask you questions about those features. Answer them as to how you want them.

The Vue CLI will now create your project...

Once created, use these commands:

terminal
cd my-vue-app
npm run serve

This will open your Vue application on http://localhost:8080. If there's already something running on port 8080, it will just increase the default port 8080 by 1.

And that's how you can create a Vue application using Vue CLI.
