学习Vue.js国际化和多语言，快速打造多语种网站！

Why You Need to Know This Stuff

Hey re, fellow web developers! Are you ready to dive into magical world of Vue.js? Well, hold on to your hats because today, we're going to talk about something that's super important in modern web development scene - internationalization and multilingual support. Why, you ask? Because world is big, and your website should be too!

Vue.js CLI Plugin: The Magic Wand

So, you want to make your Vue.js app talk in different languages? No problemo! Vue CLI has got your back with its official plugin, vue-cli-plugin-i18n. It's like a magic wand that you w*e and voilà! Your app is multilingual. Just kidding, but it's pretty close.

Setting Up Scene

Alright, let's get our hands dirty. First, you need to install Vue CLI if you h*en't already. Then, create a new project and add i18n plugin. Here's a little snippet of code that should do trick:

npm install -g @vue/cli
vue create my-vue-app
cd my-vue-app
vue add i18n

Language Files: The Recipe Book

Now, we need to create our language files. These files will contain all translations for each language we want to support. For example, let's say we want to support English and Chinese. We'll create two files, en.js and zh.js, and put m in a folder named 'lang' in our project's 'src' directory.

// src/lang/en.js
export default {
  welcome: 'Welcome to my website!',
  about: 'About',
  contact: 'Contact'
};
// src/lang/zh.js
export default {
  welcome: '欢迎来到我的网站！',
  about: '关于',
  contact: '联系'
};

The Main Event: Integrating It All

Now that we h*e our language files ready, we need to integrate m into our Vue.js app. This is where Vue I18n plugin comes into play. We'll import it into our main.js file and configure it to use our language files.，翻旧账。

// main.js
import Vue from 'vue';
import VueI18n from 'vue-i18n';
import en from './lang/en';
import zh from './lang/zh';
Vue.use(VueI18n);
const i18n = new VueI18n({
  locale: 'en', // set default locale
  messages: {
    en,
    zh
  }
});
new Vue({
  i18n,
  // ... rest of your app configuration
}).$mount('#app');

Dynamic Components: The Showtime

Now that we h*e our i18n setup, we can start using dynamic components to display correct language based on user's preference. This is where real magic happens. You can use Vue's built-in directives to bind component to current locale.
