使⽤prettier格式化（美化）代码字符串，上传提交操作Prettier格式化代码
1.简述
想必prettier⼤家都熟悉，前端的⼩伙伴们如果⽤vs code那就可能⽤过这个美化代码插件
prettier不仅是美化代码插件，它还能在代码中将字符串格式化
2.格式化代码
安装
npm i prettier
格式化html或vue
// 引⼊prettier
import prettier from"prettier/standalone";
// 引⼊格式化插件 Html
import parrHtml from"prettier/parr-html";
// 格式化代码
export function prettierCode(code){
try{
// 参数1：代码字符串，参数2：格式化配置
return prettier.format(code,{
// 使⽤html格式
parr:"html",
// 使⽤引⼊的插件parrHtml格式化
plugins:[parrHtml],
// 允许vue脚本
vueIndentScriptAndStyle:true,
});
}catch(error){
// 如果格式化失败，返回源码
return code;
裹尸还}
}
效果
未格式化
<template><div id="app"><router-view/></div></template>
<script>export default {name: 'MagicTemplateWebApp',data() {return {};},mounted() {},methods: {},};
</script>
<style lang="scss"></style>
格式化后的⽂本
<template>
<div id="app">
<router-view/>
</div>
</template>周公解梦原版大全
<script>
export default {
name: 'MagicTemplateWebApp',
data() {
data() {
return {
};
},
mounted() {
},
methods: {
},
};
</script>
<style lang="scss">
</style>
