如何连接我的 angular2 应用程序 javascript 文件 [英] How do I concattinate my angular2 app javascript files
问题描述
对于我的 angular2 typescript 应用程序，我将所有 js 文件合并到一个 app.min.js 文件中，然后将该文件 System.import 到我的 index.html 页面.
For my angular2 typescript app I concat all my js files into one app.min.js file, then System.import this file to my index.html page.
然后，我的控制台日志中出现多个匿名 System.register 调用在同一个模块文件中错误.
I then get a Multiple anonymous System.register calls in the same module file error in my console log.
我将所有 Javascript 文件(不是库)放入 app.min.js 中，然后在我的 index.html 页面上使用 system.import 导入该文件以导入该 js 文件.
I put all my Javascript files (not libraries) into app.min.js and then on my index.html page I then import the file using system.import to import that js file.
当我将所有 Javascript 文件合并到一个文件中时，我会按照一定的顺序进行操作.
When I concat all the Javascript files into one file I do them in a certain order.
也许我的配置中缺少一些参考或设置?
Maybe I'm missing some references or settings in my configs?
这是我的 index.html 页面:

这是我的 gulp 文件:
var gulp = require('gulp');
var concat = require('gulp-concat');
gulp.task('app', function() {
return gulp.src(['src/app/app.component.js', 'src/app/*.js', 'src/app/filters/*.js', 'src/app/models/**/*.js', 'src/app/components/**/*.js', 'src/app/services/**/*.js'])
.pipe(concat('app.min.js'))
.pipe(gulp.dest('src/app'));
});
gulp.task('default', ['app']);
这是我的 tsconfig.json
{
"compilerOptions": {
"target": "ES5",
"module": "system",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
},
"exclude": [
"node_modules"
]
}

推荐答案
其实你不能自己concat typescript编译器生成的js文件.
In fact you can't concat js files by your own that are generated by the typescript compiler.
如果您想将它们全部放在一个文件中，则需要在 tsconfig.json 文件中利用编译器的 outFile 属性:
If you want to have all of them in a single file, you need to leverage the outFile property of the compiler in the tsconfig.json file:
{
"compilerOptions": {
"target": "ES5",
"module": "system",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false,
"outFile": "app.js" <-------
},
"exclude": [
"node_modules"
]
}
