我第一次尝试使用 webpack 时遇到了困难。
我在浏览器控制台中收到以下错误。

我已经包含了 jquery-sparkline，但我仍然收到该错误。我可以在 vendor.js 中看到迷你图代码，但它似乎没有任何区别。
我还查看了 vendor list 文件，它包含这个但没有提到迷你图。
"./node_modules/jquery-sparkline/jquery.sparkline.js":{
"id":101,
"meta":{
}
}
我也不明白为什么我必须将下面的 ProvidePlugin 放在两个文件中。当然一次应该足够了，但是当它只在 vendor 文件中时，我收到浏览器错误，说它找不到 $。
new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery' })
如有任何帮助，我们将不胜感激!
谢谢
请您参考如下方法:
看起来您正在使用 angular-netcore。
在这种情况下，您需要为迷你图安装types，因为还没有准备好，您必须创建一个。
ClientApp/typings/sparkline/index.d.ts
index.d.ts
// Generated by typings
// Source: ClientApp/typings/sparkline/index.d.ts
interface JQuery {
sparkline(values?: string | Array<(string | number)>, opts?: sparkline.Settings): any;
}
declare namespace sparkline {
interface Settings {
type?: string;
barColor?: string;
width?: string | number;
height?: string;
lineColor?: string;
fillColor?: string | number;
chartRangeMin?: string | number;
chartRangeMax?: string | number;
composite?: boolean;
enableTagOptions?: boolean;
tagOptionPrefix?: string;
tagValuesAttribute?: string;
disableHiddenCheck?: boolean;
}
}
接下来你需要向全局声明:
typings install --global --save file:./ClientApp/typings/sparkline/index.d.ts
如果你没有typings，你可以安装
yarn install typings
最后将 jquery-sparkline 添加到 boot.browser.ts
boot.browser.ts
import 'reflect-metadata';
import 'zone.js';
import 'bootstrap';
import 'jquery-sparkline';
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.browser.module';
...
因为 boot.browser.ts 是客户端包的配置，适合在浏览器中运行。
!!!重要
不要将 import 'jquery-sparkline'; 放入应用程序/组件，因为我们不想注入(inject)到 boot.server (会抛出错误原因服务器端预渲染)。
此处需要完整的代码示例:dotnet-core-angular-sparkline
