我在我的Angular 2项目中使用带有SystemJS的Typescript进行模块加载,使用Gulp进行任务运行。项目中当前版本的Angular是RC2,但RC1也存在问题。我按照brando的回答here的步骤进行了操作。
捆绑我的应用程序并初始加载网站SystemJS后会抛出错误:
错误:http://localhost:57462/app/app.bundle.js被检测为注册但未执行。
该应用程序可以正常工作,但控制台中的错误肯定不是一件好事。
我在空项目上测试了我的配置并且问题再次出现,所以我认为问题在于配置。
这是:
Gulpfile
var gulp = require('gulp');
var sourcemaps = require('gulp-sourcemaps');
var concat = require('gulp-concat');
var typescript = require('gulp-typescript');
var jspm = require('gulp-jspm-build');
gulp.task('compile:ts', function () {
return gulp.src(['./appTS/**/*.ts'])
.pipe(sourcemaps.init())
.pipe(typescript({
noEmitOnError: true,
target: 'ES5',
removeComments: false,
experimentalDecorators: true,
emitDecoratorMetadata: true,
module: 'system',
moduleResolution: 'node'
}))
.pipe(sourcemaps.write('./'))
.pipe(gulp.dest('./app/'));
});
gulp.task('copy:vendor', function () {
return gulp.src([
'node_modules/systemjs/dist/system-polyfills.js',
'node_modules/reflect-metadata/Reflect.js',
'node_modules/core-js/client/shim.min.js',
'node_modules/zone.js/dist/zone.min.js',
'node_modules/systemjs/dist/system.js',
'node_modules/rxjs/bundles/Rx.js'
]).pipe(gulp.dest('./assets/vendor/'));
});
gulp.task('bundle:app', ['compile:ts'], function () {
return jspm({
bundleOptions: {
minify: true,
mangle: false
},
bundleSfx: true,
bundles: [
{ src: './app/main.js', dst: 'bundle.js' }
]
})
.pipe(gulp.dest('./app/'));
});
gulp.task('bundle', ['bundle:app', 'copy:vendor'], function () {
return gulp.src([
'./assets/vendor/Reflect.js',
'./assets/vendor/shim.min.js',
'./assets/vendor/zone.min.js',
'./app/bundle.js'])
.pipe(concat('app.bundle.js'))
.pipe(gulp.dest('./app/'))
});
gulp.task('default', ['bundle']);

var packages = {
app: {
format: 'register',
defaultExtension: 'js'
},
"symbol-observable": { main: 'index.js', defaultExtension: 'js' },
"reflect-metadata": { main: 'Reflect.js', defaultExtension: 'js' }
};
var ngPackageNames = ['common',
'compiler',
'core',
'http',
'platform-browser',
'platform-browser-dynamic',
'router',
'router-deprecated',
'upgrade'];
ngPackageNames.forEach(function (element, index, array) {
packages['@angular/' + element] = { main: 'bundles/' + element + '.umd.min.js', defaultExtension: 'js' };
});
System.config({
main: 'dispel.bundle.min',

您是否尝试在bundle:app
gulp任务中使用SystemJS Builder而不是jspm?

也许这可能会有所帮助:
System.config({
"meta": {
"app.bundle.js": {
"format": "register"
}
}
});

我尝试使用gulp
和Angular 2.4
捆绑生产,但所有示例都有阻塞问题;即使git clone
工作示例也不起作用。我终于通过使用angular2-webpack-starter并在那里复制我的文件来实现它。事实证明,与使用SystemJS
相比,依赖项很容易管理,您必须添加system.config.js
并希望依赖项遵循SystemJS
所需的模式。

通过使用Gulp,我们可以捆绑我们的项目,但我提取ng build或npm build for bundling keep gulp仅适用于任务运行者
