How to build scalable web applications using Vue.js and Ruby language

In recent years, with the development of web applications and the growing demand, building scalable web applications has become an important topic . As a lightweight JavaScript front-end framework, Vue.js provides a flexible, efficient and scalable solution. At the same time, Ruby, as a concise and easy-to-read programming language, can be used to construct powerful back-end systems. This article will introduce how to combine Vue.js and Ruby language to build scalable web applications, and attach corresponding code examples.

First, we need to create a basic project structure. In the root directory of the project, use a Ruby command line tool (such as Bundler) to create a new Ruby application and install the necessary dependencies:

bundle init

Then, add in the Gemfile file Necessary Ruby libraries and frameworks, such as Ruby on Rails:

gem 'rails'

Run the following command to install dependencies:

bundle install

Next, we need to create a simple Ruby on Rails controller and view for Render our Vue.js application. Execute the following command in the console:

rails generate controller Welcome index

Then, open the generated app/controllers/welcome_controller.rb file and add the following code:

class WelcomeController < ApplicationController
  def index
  end
end

Next, create a A view file named index.html.erb with the path app/views/welcome and add the following code:

<h1>Welcome#index</h1>
<div id="app"></div>

## in the root directory Create a JavaScript file named app.js in the #app/assets/javascripts folder and add the following content:

import Vue from 'vue'
import App from './app.vue'

document.addEventListener('DOMContentLoaded', () => {
  const app = new Vue({
    el: '#app',
    render: h => h(App)
  }).$mount()
})

Create a JavaScript file named

app. The Vue component of vue, the path is app/assets/javascripts, and add the following code:

<template>
  <div>
    <h2>{{ message }}</h2>
    <button @click="increment">{{ count }}</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello Vue.js!',
      count: 0
    }
  },
  methods: {
    increment() {
      this.count++
    }
  }
}
</script>

At this point, we have completed the basic front-end and back-end integration settings. Next, we need to use Webpack to build and package our Vue.js application. First, install Webpack and related dependencies:

npm init -y
npm install --save-dev webpack webpack-cli vue-loader vue-template-compiler

Then, create a Webpack configuration file named

webpack.config.js and add the following content:

const path = require('path')

module.exports = {
  entry: './app/assets/javascripts/app.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'public')
  },
  module: {
    rules: [
      {
        test: /.vue$/,
        use: 'vue-loader'
      }
    ]
  }
}

Connect Next, we need to modify the

app/views/welcome/index.html.erb file and replace the previous

fragment for

<%= javascript_pack_tag 'bundle' %>

.

Now, we can run Webpack to build our Vue.js application:

npx webpack --mode development

Finally, we need to start the Ruby on Rails server to view and test our web application:

rails server

Open

http://localhost:3000 in your browser, you will see a welcome page with a Vue.js counter button. When you click the button, the counter value will be incremented.

Through the above method, we successfully combined Vue.js and Ruby language to build a scalable web application. Vue.js provides powerful front-end development capabilities, while the Ruby language provides flexible and easy-to-use back-end support. With this combination, we are able to create high-performance and scalable web applications.

The above are the detailed steps for building scalable web applications using Vue.js and Ruby language. Through reasonable front-end and back-end integration and technology selection, we can build scalable web applications that adapt to different needs. Hope this article helps you!
