This code sets up internationalization for a Vue.js application using the vue-i18n library.

First, it imports the necessary libraries, Vue and VueI18n. It also imports the language files for English and Chinese from the locale folder.

Then, it uses Vue.use() to install the VueI18n plugin.

The messages variable is an object that contains the language messages for each locale. It is set up with the imported language files.

The i18n variable is a new instance of VueI18n. It is configured with the default locale, which is retrieved from the uni.getStorageSync('lang') function. If the lang value is not found in the storage, the default locale is set to 'zh-CN'. The messages object is also passed to the i18n instance.

Finally, the i18n instance is exported as the default export of the module, so it can be used in other parts of the application
