首先找到文档:https://www.tslang.cn/samples/index.html
寻找到vue.js
跳转过去后就是教程,我们跟着教程一步一步来
首先新建一个空项目
然后新建src
目录和components
目录
typescript-vue-tutorial/
├─ dist/
└─ src/
└─ components/
输入命令下载依赖
代码语言:javascript复制D:fileprojectsvue-ts-demo>cnpm install --save-dev typescript webpack webpack-cli ts-loader css-loader vue vue-loader vue-template-compiler
很快就下载完毕
然后初始化ts
环境
tsc --init
可以看到多出了ts
配置文件
我们可以在这里看到全部配置,我们可以手动对齐进行更改
也可以直接使用官方提供的配置
代码语言:javascript复制{
"compilerOptions": {
"outDir": "./built/",
"sourceMap": true,
"strict": true,
"noImplicitReturns": true,
"module": "es2015",
"moduleResolution": "node",
"target": "es5"
},
"include": [
"./src/**/*"
]
}
然后我们再新建一个webpack.config.js
到根目录下:
var path = require('path')
var webpack = require('webpack')
const VueLoaderPlugin = require('vue-loader/lib/plugin')
module.exports = {
entry: './src/index.ts',
output: {
path: path.resolve(__dirname, './dist'),
publicPath: '/dist/',
filename: 'build.js'
},
module: {
rules: [
{
test: /.vue$/,
loader: 'vue-loader',
options: {
loaders: {
// Since sass-loader (weirdly) has SCSS as its default parse mode, we map
// the "scss" and "sass" values for the lang attribute to the right configs here.
// other preprocessors should work out of the box, no loader config like this necessary.
'scss': 'vue-style-loader!css-loader!sass-loader',
'sass': 'vue-style-loader!css-loader!sass-loader?indentedSyntax',
}
// other vue-loader options go here
}
},
{
test: /.tsx?$/,
loader: 'ts-loader',
exclude: /node_modules/,
options: {
appendTsSuffixTo: [/.vue$/],
}
},
{
test: /.(png|jpg|gif|svg)$/,
loader: 'file-loader',
options: {
name: '[name].[ext]?[hash]'
}
},
{
test: /.css$/,
use: [
'vue-style-loader',
'css-loader'
]
}
]
},
resolve: {
extensions: ['.ts', '.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js'
}
},
devServer: {
historyApiFallback: true,
noInfo: true
},
performance: {
hints: false
},
devtool: '#eval-source-map',
plugins: [
// make sure to include the plugin for the magic
new VueLoaderPlugin()
]
}
if (process.env.NODE_ENV === 'production') {
module.exports.devtool = '#source-map'
// http://vue-loader.vuejs.org/en/workflow/production.html
module.exports.plugins = (module.exports.plugins || []).concat([
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: '"production"'
}
}),
new webpack.optimize.UglifyJsPlugin({
sourceMap: true,
compress: {
warnings: false
}
}),
new webpack.LoaderOptionsPlugin({
minimize: true
})
])
}
再到package.json
中添加构建配置
{
"devDependencies": {
"css-loader": "^6.5.1",
"ts-loader": "^9.2.6",
"typescript": "^4.5.4",
"vue": "^2.6.14",
"vue-loader": "^15.9.8",
"vue-template-compiler": "^2.6.14",
"webpack": "^5.65.0",
"webpack-cli": "^4.9.1"
},
"scripts": {
"build": "webpack",
"test": "echo "Error: no test specified" && exit 1"
}
}
我尝试构建,但发现以下错误
报错日常了属于是,仔细看,它说:
代码语言:javascript复制D:fileprojectsvue-ts-demo>cnpm run build
> @ build D:fileprojectsvue-ts-demo
> webpack
[webpack-cli] 无效的 配置 对象. Webpack 已经 被 序列化了 使用 一个 配置 类 为 并 不 匹配 它的 API 模式.
- configuration.devtool 应该 满足 表达式 "^(inline-|hidden-|eval-)?(nosources-)?(cheap-(module-)?)?source-map$".
突破 变更 自从 webpack 5: 这个 devtool 选项 变得 更加 严格.
Please strictly follow the order of the keywords in the pattern.
npm ERR! code ELIFECYCLE
npm ERR! errno 2
npm ERR! @ build: `webpack`
npm ERR! Exit status 2
npm ERR!
npm ERR! Failed at the @ build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:

所以我们将webpack.config.js
中的configuration.devtool
改为表达式中的eval-nosources-cheap-module-source-map
再来,发现报错变了
它说是找不到这个文件
那我们新建一个,这就是我们的主要ts
文件
// src/index.ts
import Vue from "vue";
let v = new Vue({
el: "#app",
template: `
<div>
<div>Hello {{name}}!</div>
Name: <input v-model="name" type="text">
</div>`,
data: {
name: "World"
}
});
添加完成之后我们再次构建,发现成功构建啦!
代码语言:javascript复制# 编译
cnpm run build
# 编译并热更新
npm run build -- --watch
这里还有个警告,说我们缺少了mode
属性
我们顺便加上
警告消失
接下来我们添加一个组件到src/components
下
// src/components/Hello.ts
import Vue from "vue";
export default Vue.extend({
template: `
<div>
<div>Hello {{name}}{{exclamationMarks}}</div>
<button @click="decrement">-</button>
<button @click="increment"> </button>
</div>
`,
props: ['name', 'initialEnthusiasm'],
data() {
return {
enthusiasm: this.initialEnthusiasm,
}
},
methods: {
increment() { this.enthusiasm ; },
decrement() {
if (this.enthusiasm > 1) {
this.enthusiasm--;
}
},
},
computed: {
exclamationMarks(): string {
return Array(this.enthusiasm 1).join('!');
}
}
});
在index.ts
中引用
// src/index.ts
import Vue from "vue";
import HelloComponent from "./components/Hello";
let v = new Vue({
el: "#app",
template: `
<div>
Name: <input v-model="name" type="text">
<hello-component :name="name" :initialEnthusiasm="5" />
</div>
`,
data: { name: "World" },
components: {
HelloComponent
}
});
注意到此为止我们都是使用ts
文件进行编写vue
代码,如果我们需要使用vue
文件,则需要在src
下新建vue-shims.d.ts
// src/vue-shims.d.ts
declare module "*.vue" {
import Vue from "vue";
export default Vue;
}
我们的组件就可以改为Hello.vue
<!-- src/components/Hello.vue -->
<template>
<div>
<div class="greeting">Hello {{name}}{{exclamationMarks}}</div>
<button @click="decrement">-</button>
<button @click="increment"> </button>
</div>
</template>
<script lang="ts">
import Vue from "vue";
export default Vue.extend({
props: ['name', 'initialEnthusiasm'],
data() {
return {
enthusiasm: this.initialEnthusiasm,
}
},
methods: {
increment() { this.enthusiasm ; },
decrement() {
if (this.enthusiasm > 1) {
this.enthusiasm--;
}
},
},
computed: {
exclamationMarks(): string {
return Array(this.enthusiasm 1).join('!');
}
}
});
</script>
<style>
.greeting {
font-size: 20px;
}
</style>
index.ts
中HelloComponent
我再给个后缀
// src/index.ts
import Vue from "vue";
import HelloComponent from "./components/Hello.vue";
let v = new Vue({
el: "#app",
template: `
<div>
Name: <input v-model="name" type="text">
<hello-component :name="name" :initialEnthusiasm="5" />
</div>
`,
data: { name: "World" },
components: {
HelloComponent
}
});
我们使用cnpm run build
生成的build.js
我们可以放到一个html
中使用一下,看看效果
<!doctype html>
<html>
<body>
<div id="app"></div>
</body>
<script src="./dist/build.js"></script>
</html>
效果如下:
但这和我们一般vue
开发还有点差别,我们开发时应该还有热重载…
我们去修改下webpack.config.js
然后重新运行cnpm run build -- --watch
然后我们打开页面http://127.0.0.1:8848/vue-ts-demo/index.html
我们修改后再次保存,就可以实时更新了
