如何使用 VS Code 在 .vue 文件中使用 Typescript? [英] How to work with Typescript in .vue files using VS Code?
问题描述
我使用的是 Visual Studio Code、Vue 2(webpack 模板)和 Typescript.
这是我的 App.vue 组件:
<div id="应用程序"><导航栏></导航栏>[内容在这里]<script lang="ts">从'./components/Navbar'导入导航栏导出默认{成分: {导航栏}}
问题 1:一切正常，但我想在 <script lang="ts"> 标签中包含智能感知，因为它发生在 .ts 文件中，那么我该如何实现那个?
问题 2:在我的 main.ts 中，我有 import App from './App'，但./App"用红色下划线标出，因为 VS Code 找不到 .ts 文件.有没有办法让编辑器在编译前(在编辑时)识别 .vue?

对于 Q1，将 Typescript 代码放到单独的 script.ts 文件中，并包含在 App.vue 中代码>喜欢:
对于 Q2，按照@Oswaldo 的建议，您可以定义一个 vue.d.ts 文件，其内容如下:
声明模块'*.vue'{import Vue = require('vue')const 值:Vue.ComponentOptions导出默认值} 如果您将此文件放在 ${Project_ROOT}/typings 文件夹中，则需要将此类型文件包含在您的 tsconfig.json 中，例如
"typeRoots": ["./typings"]然后你可以导入带有.vue后缀的*.vue文件:
从'./App.vue'导入应用程序如果你不喜欢包含 .vue 后缀，你可以将所有 Vue 组件放在一个文件夹中，例如 src/components 并更改 vue.d.ts 如下:
声明模块 'src/components/*' {import Vue = require('vue')const 值:Vue.ComponentOptions导出默认值} src 被定义为 webpack.base.conf.js 作为绝对路径的别名.
解析:{扩展名:['.js', '.vue', '.json', '.ts'],别名:{'vue$': 'vue/dist/vue.esm.js','src':解析('src')}}然后需要使用完整路径导入一个没有.vue后缀的组件:
从'src/components/App'导入应用程序两者都不是优雅的解决方案，但红色下划线消失了.
I'm using Visual Studio Code, Vue 2 (webpack template) and Typescript.
This is my App.vue component:
<template>
<div id="app">
<navbar></navbar>
[content here]
</div>
</template>
<script lang="ts">
import Navbar from './components/Navbar'
export default {
components: {
Navbar
}
}
</script>
Question 1: Everything is working fine, but I would like to have intellisense inside <script lang="ts"> tag as it happens in .ts files, so how can I achieve that?
Question 2: In my main.ts I have import App from './App', but "./App" is underlined in red since VS Code can't find the .ts file. Is there a way to make the editor recognizes .vue before compile time (in editing time)?
Update (2018-03-25): I highly recommend everyone who wants to setup typescript to read this
For Q1, put the Typescript code into a separate script.ts file and include it in App.vue like:
<script lang="ts">
import s from './script'
export default s
</script>
For Q2, as suggested by @Oswaldo, you can defined a vue.d.ts file that has the following content:
declare module '*.vue' {
import Vue = require('vue')
const value: Vue.ComponentOptions<Vue>
export default value
}
If you put this file in the ${Project_ROOT}/typings folder, you need to include this type file in your tsconfig.json like
"typeRoots": ["./typings"]
Then you can import *.vue file with the .vue postfix:
import App from './App.vue'
If you don't like to include the .vue postfix, you can put all Vue components in a single folder such as src/components and change the vue.d.ts as the following:
declare module 'src/components/*' {
import Vue = require('vue')
const value: Vue.ComponentOptions<Vue>
export default value
}
The src is defined webpack.base.conf.js as an alias for an absolute path.
resolve: {
extensions: ['.js', '.vue', '.json', '.ts'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'src': resolve('src')
}
}
Then you need to use the full path to import a component without the .vue postfix:
import App from 'src/components/App'
Both are not elegant solutions but the red underline is gone.
