在 vue 项目中，引入模块路径时使用 @ 符号，那么 @ 符号的含义是什么呢

其实 @ 的作用就是进行路径映射，减少代码量。具体的映射关系可以在 webpack 配置文件中定义，如下示例

 

打开 webpack.base.config.js 文件

上图中 @ 映射上级目录下的 src 目录

【代码】NestJS 中，@ 符号是有什么含义。
vue中import引入模块时路径使用@符号，vue中路由懒加载的@符号

1、ES6中的重要一个内容就是：模块化 1）、export： 用户对外输出本模块（前端一个js文件可以理解为一个模块，eg：request.js）变量的接口 。 2）、import： 用于在一个模块中加载另一个含有 export 接口的模块（这个 js 文件一定要含有 export ）。 3）、而我们在使用 import 导入一个模块的时候通常这样使用： import util from ‘@/utills/request.js’ 或者路由懒加载： component: () => import(’@
Android之工程目录lib和libs区别
LVXIANGAN的专栏

mark一下两者的区别： 1、放在lib中的是被reference的，放在libs中的是被include的。 2、放在libs中的文件会自动被Eclipse所include。所以不要把API放到libs里去。 3、lib的内容是不会被打包到APK中，libs中的内容是会被打包进APK中。   总结： lib：jar包只是参与编译，让工程顺利运行，但打包不会jar加到生成apk里面； li...
vue项目中有时间文件路径上有@，代表什么意思？
飞翔的熊blabla

./这是相对路径的意思，同级目录。 ../上级目录。 @/这是webpack设置的路径别名。 在build/webpack.base.conf这个文件里面设置了@具体指的是什么 resolve: { // 路径别名 alias: { '@': resolve('src'), 'vue$': 'vue/dist/vue.esm.js' } }, 就是说@这东西代表着到src这个文件夹的路径。...
node.js及npm、vue等js类框架中@的用法
細水、長流√的专栏

首先，“@”是一个符号，电子信箱中意义为“at”，即“某用户”在“某服务器”。好了，关于在前端nodejs中相关项目中经常出现的@符号就总结到此，还有哪些小编不知道的用法，还请博友在下面留言补充，以完善知识，利于学习之用。二、在npm中，与“/”相结合，置于包的名字前，表示该包的范围，即指示该包属于某个用户或组织，是该用户或组织提供的私有或公有包。三、node.js中，符合ES6标准的import命令中出现的@， 如。四、Vue的元素标签中，@”是指令“v-on”的缩写。
import Util from '@/libs/util'
07-25
C知道：您在代码中使用了ES6的模块导入语法。...import Util from '@/libs/util'; ``` 然后您就可以使用`Util`来调用该工具库提供的功能了。请注意，具体的功能和使用方法需要根据工具库的实现来确定。
