问题描述
例如:
import Component from '@/components/component'
在我看的代码中,它表现得像 ../
上升一个级别在相对于文件路径的目录中,但我想更一般地了解它的作用。遗憾的是,由于符号搜索问题,我无法在线找到任何文档。
In the code I'm looking at it behaves like ../
going up one level in the directory relative to the file path, but I'd like to know more generally what it does. Unfortunately I can't find any documentation online due to the symbol searching problem.
推荐答案
模块标识符的含义和结构取决于模块加载器或模块捆绑。模块加载器不是ECMAScript规范的一部分。从JavaScript语言的角度来看,模块标识符完全不透明。所以它真的取决于你使用的是哪个模块加载器/捆绑器。
The meaning and structure of the module identifier depends on the module loader or module bundler. The module loader is not part of the ECMAScript spec. From a JavaScript language perspective, the module identifier is completely opaque. So it really depends on which module loader/bundler you are using.
你很可能有像。
基本上它意味着来自项目的根 ..它避免了从'../../../../components/component'导入组件等内容code>
Basically it means from the root of the project.. it avoids having to write things like import Component from '../../../../components/component'
编辑:存在的一个原因是因为从'components / component'导入组件
不会这样做,而是搜索 node_modules
文件夹
One reason it exists is because import Component from 'components/component'
doesn't do that but instead search in the node_modules
folder
