Vue.js: welcome CLI

5th September, 2017 - 3 min. read - in Tutorials - Go to Index

In this article, I’ve documented my experience on getting started with Vue.js.

This time, I wanted to start using the official suggested setup, which supports the .vue file format and other very interesting features.

The setup configuration is quite complex, however, with the vue-cli (the Vue Command Line Interface) it’s a no brainer task.

All you have to do is to install it on your system using node and npm with:

npm install -g vue-cli

Once you have the CLI installed, you can run vue commands (from the Terminal/Shell) in order to bootstrap empty projects ready to start with alongside powerful features such as ES6 transpiler, hot reloading, CSS scoped, just to mention a few.

You can choose between different scaffolding projects, based on complexity and thoroughness, my choice has been (with a proper projectName):

vue init webpack-simple <projectName>

After that, you need to install the modules and run the development session:

cd <projectName>
npm install
npm run dev

Your browser should run with a sample Vue app. If you edit some files you should see the change almost in real time.

With this setup, the src folder is the place for the source files. A minimal Vue app needs the following files in order to compile correctly:

Each .vue file is a component that means:

<template></template>

<script></script>

<style></style>

A markup fragment, a script for business logic, a local style definition. That’s all soo right.

I’ve always struggled with the css and js folders full of files of the same type but not related in any ways to each other. The component structure resonates much more clear to me.

Creating a component

Create and save a new .vue file (let’s say MyComponent.vue) within the src folder. Add the three parts belonging to a component (at least the template, optionally with script and style):

<template>
  <div>
    <h1>Thi is a component title</h1>
  </div>
</template>

and use it from within any other .vue file with this code:

<template>
  <div>
    <mycom />
  </div>
</template>


<script>
import mycom from './MyComponent.vue'

export default {
  components: {
    mycom
  }
}
</script>

This way the markup, the style and the logic will be rendered within the above main component.

Even better

So far, Vue.js is very promising to me. Everything is crystal clear and I really love the way it can be learned incrementally. Then, by chance, I’ve discovered Nuxt.

I’ve spent a lot of time over the last few years trying to figure out a way to develop front-end apps with happiness. I’ve even developed and released a couple of libraries (static-player and grunt-static-player) to develop web apps using dynamic injections with the possibility to bake it as static web app (for SEO and performance purposes). We currently use them for our web projects but, for the first time, I’m seriously considering to dismiss them in favor of Vue.js+Nuxt.

After a first check, I do believe they are awesome and they will be a game changer. Try it with:

vue init nuxt-community/starter-template <projectName>

and follow the well-done documentation here.

More to come…
