如何使用SystemJS和Gulp准备发布版本？

我在Angular2项目中使用SystemJS.我为TypeScript使用tsconfig文件.我想使用gulp来连接和缩小我的生产版代码.我在解决代码方面遇到了问题:每次尝试连接文件时都会得到"angular"未定义或"system"未定义.我试图修改我尝试从节点模块加载文件的顺序,但是我没有成功.

我想知道你们是否有这个问题,并找到答案吗？

这是我的gulp文件:

var gulp = require('gulp'),
            .....


var paths = {
    dist: 'dist',
    vendor: {
        js: [
            'node_modules/systemjs/dist/system.src.js',
            'node_modules/angular2/bundles/angular2.dev.js',
            'node_modules/angular2/bundles/angular2-polyfills.js',
            'node_modules/angular2/bundles/router.dev.js'
             ...
        ],
        css: []
},
    app: {
        templates: [
            'app/**/*.html',
            '!node_modules/*.html'
        ],
        scripts: [
            'app/**/*.ts',
            'app/config.ts',
            'app/app.ts'
        ]
    }
};

var tsProject = ts.createProject('tsconfig.json', {
    out: 'Whatever.js'
});

gulp.task('dev:build:templates', function () {
    return gulp.src(paths.app.templates)
        .pipe(ngHtml2Js({
            moduleName: 'Whatever',
            declareModule: false
        }))
        .pipe(concat("Whatever.tpls.min.js"))
        .pipe(gulp.dest(paths.dist));
});
gulp.task('prod:build:templates', function () {
    return gulp.src(paths.app.templates)
        .pipe(minifyHtml({
            empty: true,
            spare: true,
            quotes: true
        }))
        .pipe(ngHtml2Js({
            moduleName: 'whatever',
            declareModule: false
        }))
        .pipe(concat(paths.appName + ".tpls.min.js"))
        .pipe(uglify())
        .pipe(gulp.dest(paths.dist));
});

gulp.task('dev:build:scripts', function () {
    var tsResult = tsProject.src()
        .pipe(sourcemaps.init())
        .pipe(ts(tsProject));

    return tsResult.js
        .pipe(sourcemaps.write({
            sourceRoot: '/app'
        }))
        .pipe(concat('whatever.js'))
        .pipe(gulp.dest(paths.dist));
});

gulp.task('dev:build:styles', function () {
    return gulp.src(paths.app.styles)
        .pipe(sass())
        .pipe(gulp.dest(paths.dist + '/css'));
});
gulp.task('dev:build:vendor', function () {
    return gulp.src(paths.vendor.js)
        .pipe(concat('vendor.min.js'))
        .pipe(gulp.dest(paths.dist))
});

gulp.task('dev:build', [
    'dev:build:vendor',
    'dev:build:templates',
    'dev:build:scripts',
    'dev:build:styles',
], function () {
});

这是我加载文件的方式:

以下是我得到的错误:

Uncaught TypeError: Unexpected anonymous System.register call.(anonymous function) @ vendor.min.js:2680load.metadata.format @ vendor.min.js:3220oldModule @ vendor.min.js:3749(anonymous function) @ vendor.min.js:2411SystemJSLoader.register @ vendor.min.js:2636(anonymous function) @ Whatever.js:2
Whatever.tpls.min.js:1 Uncaught ReferenceError: angular is not defined

您将收到"意外的匿名System.register调用",因为没有按正确的顺序加载引用.我使用JSPM来正确构建我的角度应用程序以进行生产.该过程分为4个部分.

第1部分:编译您的打字稿文件

var ts = require("gulp-typescript");
var tsProject = ts.createProject("./App/tsconfig.json");
gulp.task("compile:ts", function () {
    var tsResult = tsProject.src()
        .pipe(ts(tsProject));
    tsResult.js.pipe(gulp.dest("./wwwroot/app"));

});

System.config({
  baseURL: "/",

  paths: {
    "npm:*": "jspm_packages/npm/*",

  },

});
//this will create a file called boot.bundle.min.js
//note I have set jspm to create a self-executing bundle
