我正在开发一个库,以便使用TypeScript在网络浏览器中使用。
我正在使用"系统"作为模块编写单独的打字脚本文件,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。但是
我也想从网络浏览器中使用它。我想把所有的.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捆绑包生成了一个.d.ts文件,并尝试从两种方式捆绑.js文件:
使用concat:
gulp.src('dist/js/src/**/*.js') .pipe(concat('Ng2Emulation-bundle.js')) .pipe(gulp.dest('dist/release'));
使用tsify:
browserify() .add('src/ng2emulation.ts') .plugin(tsify, { noImplicitAny: false }) .bundle() .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,会出现以下错误:

我使用的是Visual Studio 2013,一个MVC ASP.NET应用程序。我的主html(_layout.cs.html)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:<script src="~/Scripts/Ng2Emulation-bundle.js"></script>
加载捆绑包,并从system.config
中删除Ng2Emulation
映射,但我运气不好:(
我认为在捆绑包创建过程中或后面的模块中有一些我不理解的地方。。。
如何捆绑?我该怎么做?
是的,经过深入搜索,我找到了一种方法。我找到了systemjs构建器项目。我在我的gull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);
});
});
我在查看Angular2 gull文件时发现:D现在我可以使用html script
标签包含该文件,我的html如下所示:
<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>
它就像一个符咒。
不过,如果有人知道其他方法,我很想知道。我不明白什么mudule系统更好,当使用其中一个或另一个时。。。
