webpack配置,不需要配置externals,webpack具体配置如下,
const webpack = require(‘webpack‘);
const path = require(‘path‘);
const htmlWebpackPlugin = require(‘html-webpack-plugin‘);
const { CheckerPlugin } = require(‘awesome-typescript-loader‘)
// 设置dev环境或pro环境
const WEBPACK_ENV = process.env.WEBPACK_ENV || ‘dev‘;
// 对babel的配置,内容同.babelrc文件
const babelOptions = {
"presets": [
[
"env",
{
"targets": { "browsers": ["last 2 versions", "safari >= 7"] }
},
]
]
};
// htmlWebpackPLugin 默认配置
var getHtmlConfig = function (name, title) {
return {
template: ‘./src/views/‘ + name + ‘.html‘,
filename: ‘./views/‘ + name + ‘.html‘,
// favicon: ‘./favicon.ico‘,
title: title,
inject: true,
hash: true,
};
};
// 获取页面地址
var getInitEntryModal = function (name) {
return [path.join(__dirname, ‘./src/pages/‘ + name + ‘.ts‘)];
}
// ts-loader的配置
const tsLoaderOptions = {
transpileOnly: true
};
module.exports = {
entry: {
‘index‘: getInitEntryModal(‘index‘),
},
output: {
filename: ‘./scripts/[name].js‘,
path: path.join(__dirname, ‘./dist‘),
},
resolve: {
extensions: [".webpack.js", ".web.js", ".ts", ".tsx", ".js"]
},
module: {
rules: [
{
test: /\.ts(x?)$/,
exclude: /node_modules/,
use: [
{ loader: ‘ts-loader‘, options: tsLoaderOptions },
// { loader: ‘awesome-typescript-loader‘ }
// { loader: ‘babel-loader‘, options: babelOptions },
],
}
// { test: /\.js$/, enforce: "pre", loader: "source-map-loader" },
// { enforce: ‘pre‘, test: /\.tsx?$/, use: "source-map-loader" },
// { test: /\.tsx?$/, loader: ‘awesome-typescript-loader‘, exclude: /node_modules/ },
],
},
//将外部变量或者模块加载进来, 在.ts文件中要引用jquery,下面代码屏蔽
// externals: {
// ‘jquery‘: ‘window.jQuery‘,
// },
devtool: "source-map",
plugins: [
// new webpack.LoaderOptionsPlugin({
// options: { resolve: { extensions: [".ts", ".tsx", ".js"] } }
// }),
new htmlWebpackPlugin(getHtmlConfig(‘index‘, ‘index‘)),
],
devServer: {
contentBase: path.join(__dirname, ‘./dist‘),
port: 9000,
// host: ‘192.168.81.1‘,
open: false,
hot: false,
inline: true,
compress: true,
},
}
jquery 代码测试
import $ = require("jquery");
export class App {
public addComment(): void {
let creatAt = new Date();
$("#main").append("<div><span>new comment pushed at." + creatAt.toTimeString() + "</span>");
}
}
let app = new App();
$(() => {
$("#btn-add").click(app.addComment);
});
