1、新建一个BlazorApp项目
2、新建文件夹WebLib,并在终端中打开
执行指令
npm init -y
在WebLib目录下新建tsconfg.json文件
{
"compilerOptions": {
"noImplicitAny": false,
"noEmitOnError": true,
"removeComments": false,
"sourceMap": true,
"target": "ES6",
"outDir": "../wwwroot/js",
"allowSyntheticDefaultImports": true
},
"exclude": [
"node_modules",
"wwwroot",
"Component",
"Pages",
"Layout"
],
"include": [
"**/*"
]
}
执行以下指令
// 安装pnpm,npm国内太慢，所以使用pnpm管理包
npm install -g pnpm
// 安装webpack相关依赖
pnpm install webpack webpack-cli --save-dev
// 安装ts相关依赖
pnpm install --save-dev typescript ts-loader
// 安装css相关依赖
pnpm i -D sass-loader css-loader style-loader sass
// 安装scss相关依赖(不用scss可以不装)
pnpm i -D sass-loader sass
在WebLib目录下新建webpack.config.js文件
const path = require("path");
let commonSetting = {
module: {
rules: [
{
test: /.ts$/,
use: {
loader: "ts-loader",
},
exclude: /node_modules/,
},
{
test: /\.css$/,
use: ['style-loader', 'css-loader']//程序会先加载css-loader，然后在加载style-loader文件
},
{
// 增加对 SCSS 文件的支持
test: /\.scss$/,
// SCSS 文件的处理顺序为先 sass-loader 再 css-loader 再 style-loader
use: ['style-loader', 'css-loader', 'sass-loader'],
}
]
},
devtool: "inline-source-map",
// 用来设置引用模块
resolve: {
extensions: [".ts", ".js"],
},
}
module.exports = [
{
entry: {
common: './src/common.ts',
},
output: {
path: path.resolve(__dirname, '../wwwroot/js'),
filename: "[name].js",
library: {
// umd打包出来的js,可以在html引入后直接使用里面的函数
type: 'umd'
},
},
...commonSetting
},
{
entry: {
// BlazorApp1是项目的名称，必须是这个名字
"BlazorApp1.lib.module": "./src/BlazorApp1.lib.module.ts"
},
experiments: {
outputModule: true
},
output: {
path: path.resolve(__dirname, '../wwwroot/js'),
filename: "[name].js",
library: {
// module打包出来,需要import导入后使用
type: 'module'
},
},
...commonSetting
}
];
在WebLib目录下创建src目录，并在src目录下创建common.ts，BlazorApp1.lib.module.ts文件，然后创建css目录，并在css目录下创建common.scss文件，目前目录结构如下
修改common.ts如下
import "./css/common.scss"
export function Sum(a: number, b: number) {
console.log(a+b)
}
修改BlazorApp1.lib.module.ts如下
const moduleJsList: string[] =
[
`./js/common.js`
]
function loadJs() {
for (let i of moduleJsList) {
let el = document.createElement('script');
el.setAttribute('src', i);
document.head.appendChild(el);
}
}
export function beforeWebStart() {
console.log("开始加载js")
loadJs();
}
// 这样做的目的是让common.ts里的方法能够在html里直接调用，而不需要import
修改common.scss如下
.testDiv{
font-size:30px;
font-weight:bolder;
}
修改Components/Pages/Counter.razor如下
@page "/counter"
@inject IJSRuntime jsRuntime;
<PageTitle>Counter</PageTitle>
<h1>Counter</h1>
<p role="status">Current count: @currentCount</p>
<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>
<div class="testDiv">
1231
</div>
@code {
private int currentCount = 0;
private async Task IncrementCount()
{
currentCount++;
await jsRuntime.InvokeVoidAsync("Sum", 1, 2);
}
}
package.json如下
{
"name": "weblib",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"build": "webpack --mode production",
"dev": "webpack --mode development"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"css-loader": "^6.10.0",
"sass": "^1.70.0",
"sass-loader": "^14.1.0",
"style-loader": "^3.3.4",
"ts-loader": "^9.5.1",
"typescript": "^5.3.3",
"webpack": "^5.90.1",
"webpack-cli": "^5.1.4"
}
}
最后在终端执行
npm run dev
运行项目,在Counter页面下会呈现如下效果
且点击按钮，控制台会打印3
3、调整项目文件，让其在发布和编译时自动打包
