javascript – 将一个打字稿库捆绑到一个.js文件和一个.d.ts

2023年3月21日 123次阅读

我正在开发一个使用TypeScript在webbrowser中使用的库.

我正在使用“system”作为–module将单独的打字稿文件编写为模块,例如这是主文件：

/// <reference path="../typings/tsd.d.ts" />
/// <reference path="./typings/simple-html-tokenizer/simple-html-tokenizer" />

export * from "./Decorators/Component";
export * from "./Decorators/Directive";
export * from "./Decorators/Inject";
export * from "./Decorators/Injectable";
export * from "./Events/EventEmitter";
export * from "./Core/Bootstrap";
export * from "./Decorators/Output";
export * from "./Decorators/Input";
export {OnChanges, OnInit, OnDestroy} from "./Core/LifeCycle/LifeCycleHooks";

这是第一个模块：

import {serviceNormalize} from "../Utils/AngularHelpers";

export interface IComponentMetadata {
    template?: string;
    templateUrl?: string;
    selector?: string;
    directives?: Function[];
    outputs?: string[];
    inputs?: string[];
    styles?: string[];
    providers?: (Function|string)[];
}

/**
 * Register metadata into class to be used by bootstrap.
 */
export function Component(componentMetadata: IComponentMetadata) {
    return (target: any) => {

        /// ...
        /// ...
        /// ...

        return target;
    }
}

好吧,我正在使用gulp-typescript构建它,我将它转换为es5并为每个.ts文件创建一个.js和一个.d.ts文件.到目前为止,我有一个npm包,我可以使用其他npm项目中的项目.但……

我也想从webbrowser中使用它.我想将所有.js文件捆绑在一起并使用这种方式：

<script src="~/Scripts/Ng2Emulation-bundle.js"></script>

我使用dts-bundle生成了一个.d.ts文件,我试图从两个方面捆绑.js文件：

>使用concat：

gulp.src( ‘DIST / JS / SRC / ** / *.JS’)
    .pipe(CONCAT( ‘Ng2Emulation-bundle.js’))
    .pipe(gulp.dest( ‘DIST /释放’));
>使用tsify：

browserify()
    .新增( ‘SRC / ng2emulation.ts’)
    .plugin(tsify,{noImplicitAny：false})
    .束()
    .on(‘error’,function(error){console.error(error.toString());})
    .pipe(gulp.dest( “Ng2Emulation-bundle.js”));

有两种方法可以创建捆绑包但当我尝试从浏览器中使用它时,它会尝试加载每个模块,从而得到如下错误：

我正在使用Visual Studio 2013,一个MVC ASP.NET应用程序.我的主要html(_layout.cshtml)是这样的：

<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <link href="~/node_modules/angular-material/angular-material.css" rel="stylesheet"/>
    <script src="~/Scripts/jquery-2.2.0.js"></script>
    <script src="~/Scripts/angular.js"></script>
    <script src="~/Scripts/angular-aria.js"></script>
    <script src="~/Scripts/angular-animate.js"></script>
    <script src="~/Scripts/angular-messages.js"></script>
    <script src="~/node_modules/angular-material/angular-material.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.15/system.js"></script>
    <script type="text/javascript">
        // set our baseURL reference path
        System.config({
            baseURL: '/TypeScript',
            map: {
                "HTML5Tokenizer": "/Scripts/simple-html-tokenizer.js",
                "Ng2Emulation": "/Scripts/Ng2Emulation-es5.js"
            }
        });
        System.defaultJSExtensions = true;

        System.import('App/Boot');
    </script>
</head>
<body>
    @RenderBody()
    @RenderSection("scripts", required: false)
</body>
</html>

这是我的App / Boot.ts：

import {bootstrap, Component} from "Ng2Emulation";

@Component({
    selector: "my-app",
    template: "<h1>My First Angular 2 App</h1>"
})
export class AppComponent { }

bootstrap(AppComponent);

我试图通过以下方式加载包：< script src =“〜/ Scripts / Ng2Emulation-bundle.js”>< / script>并从system.config中删除Ng2Emulation映射,但我没有运气:(

我认为在捆绑创建过程或模块行为中有一些我不理解的东西……

如何捆绑？
我怎么能这样做？

最佳答案 是的,经过深入搜索,我找到了一种方法.

我找到了 systemjs builder项目.

我在gulp文件中写了一个任务,这样：

gulp.task("system-builder", function () {
    var builder = new Builder('dist/js/src');

    builder.config({
        meta: {
            'HTML5Tokenizer.js': { // HTML5Tokenizer is a external módule
                build: false       // Not to include in a bundle.
            }
        },
        defaultJSExtensions: true
    });

    builder
        .bundle('Ng2Emulation.js', 'dist/release/Ng2Emulation-bundle.js')
        .then(function () {
            console.log('Build complete');
        })
        .catch(function (err) {
            console.log('Build error');
            console.log(err);
        });
});

我发现它看着Angular2 gulp文件：D
现在我可以使用html脚本标记包含该文件,我的html是这样的：

<script src="~/Scripts/simple-html-tokenizer.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.15/system.src.js"></script>
<script type="text/javascript">
    // set our baseURL reference path
    System.config({
        baseURL: '/TypeScript',
        map: {
            "HTML5Tokenizer": "/Scripts/simple-html-tokenizer.js"
        }
    });
    System.defaultJSExtensions = true;
</script>
<script src="~/Scripts/Ng2Emulation-es5.js"></script>
<script type="text/javascript">

    System.import('App/Boot');
</script>

它就像一个魅力.

不过,如果有人知道其他方法,我想知道.
我不明白什么mudule系统更好,当使用其中一个,…
