我已遵循Vuejs网站上的文档,以学习如何在全球范围内注册vue组件。
我已定义components文件夹的相对路径为./global
,并设置为在子文件夹中查找true
(默认为false)。但是,它仍然没有研究子文件夹。
我还用console.logging了组件键,以查看是否包含任何vue组件,但是它只返回了全局(根)文件夹中的组件。
https://vuejs.org/v2/guide/components-registration.html
import Vue from 'vue'
import upperFirst from 'lodash/upperFirst'
import camelCase from 'lodash/camelCase'
const requireComponent = require.context(
// The relative path of the components folder
'./global',
// Whether or not to look in subfolders
true,
// The regular expression used to match base component filenames
/[A-Z]\w+\.(vue|js)$/
)
console.log(requireComponent.keys())
requireComponent.keys().forEach(fileName => {
// Get component config
const componentConfig = requireComponent(fileName)
// Get PascalCase name of component
const componentName = upperFirst(
camelCase(
// Strip the leading `./` and extension from the filename
fileName.replace(/^\.\/(.*)\.\w+$/, '$1')
)
)
// Register component globally
Vue.component(
componentName,
// Look for the component options on `.default`, which will
// exist if the component was exported with `export default`,
// otherwise fall back to module's root.
componentConfig.default || componentConfig
)
})

这是我最终为达到相同结果而写的内容:
const requireComponent = require.context(
// The relative path of the components folder
'./global',
// Whether or not to look in subfolders
true,
// The regular expression used to match base component filenames
/[A-Z]\w+\.(vue|js)$/
)
requireComponent.keys().forEach(fileName => {
// Get component config
const componentConfig = requireComponent(fileName)
// Get PascalCase name of component
const componentName = Vue._.upperFirst(
Vue._.camelCase(
fileName
.split('/')
.pop()
.replace(/\.\w+$/, '')
)
)
// Register component globally
Vue.component(
componentName,
// Look for the component options on `.default`, which will
// exist if the component was exported with `export default`,
// otherwise fall back to module's root.
componentConfig.default || componentConfig
)
})
确保全局中的所有文件都大写并具有.vue或.js扩展名。
还要使用您提供的路径来确保main.js(或任何您的引导文件)位于全局目录上。示例:
/ src main.js / global
这将使诸如ProgressBar.vue之类的文件作为ProgressBar在所有组件中全局可用
<ProgressBar></ProgressBar>

@Anson C
const requireComponent = require.context(
// The relative path of the components folder
'./global',
// Whether or not to look in subfolders
true,
// The regular expression used to match base component filenames
/[A-Z]\w+\.(vue|js)$/
)
此代码完全按预期工作。意味着它将按预期返回子文件夹中的所有文件(例如 ./Base/BaseInput.vue
将返回 BaseInput
)。但是要导入这些文件,您还必须添加相应的路径。
// Get PascalCase name of component
const componentName = upperFirst(
camelCase(
// Strip the leading `./` and extension from the filename
fileName.replace(/^\.\/(.*)\.\w+$/, '$1')
)
)
这只会导入 ./BaseInput
,它不是准确的路径,应该是 ./Base/BaseInput
。
用于:
// Get PascalCase name of component
const componentName = Vue._.upperFirst(
Vue._.camelCase(
fileName
.split('/')
.pop()
.replace(/\.\w+$/, '')
)
)
此代码返回文件和文件夹的完美路径。
