记录chrome扩展开发时调用vue-i18n的一些问题和解决方法
环境
vue
: ^3.3.4vue-i18n
: ^9.2.2vite
: ^4.4.8
错误1
Uncaught (in promise) EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'wasm-unsafe-eval' 'inline-speculation-rules' http://localhost:* http://127.0.0.1:*".

这个方法虽然可以解决报错问题,但是t
函数还是无法正常使用,如果只是简单的语言调用可以使用tm
函数
javascript
<script setup>
import {useI18n} from 'vue-i18n'
const {tm} = useI18n()
</script>
<template>
<div>
{{ tm('test') }}
</div>
</template>
javascript
// 在createI18n时,增加一个导出方法,来简单解决`t`函数不能正常用的问题
export function ts(key: string, arg: object) {
const {tm,locale} = useI18n()
let _text = tm(key);
let reg;
for(let LKey in arg){
reg = new RegExp('\{\\s*?'+LKey+'\\s*?\}','g');
// @ts-ignore
_text = _text.replace(reg, arg[LKey])
}
return _text;
}
// 使用:ts('test', {key1: 'key1Val', key2: 'key2Val'})

使用 vite 插件 vite-plugin-vue-i18n 处理这个问题
shell
npm i --save-dev @intlify/vite-plugin-vue-i18n
# 包文档: https://www.npmjs.com/package/@intlify/vite-plugin-vue-i18n (停更)
# 包作者提醒:
# This plugin support until Vite 3. If you would like to use on Vite 4, please use @intlify/unplugin-vue-i18n
npm i --save-dev @intlify/unplugin-vue-i18n

错误2
You are running the esm-bundler build of vue-i18n. It is recommended to configure your bundler to explicitly replace feature flag globals with boolean literals to get proper tree-shaking in the final bundle.
解决方案:
json
// vite.config.ts
resolve: {
alias: {
// ...
'vue-i18n': 'vue-i18n/dist/vue-i18n.runtime.esm-bundler.js'
},
},
