I'm using Typescript with SystemJS for module loading and Gulp for task runner in my Angular 2 project. The current version of Angular in the project is RC2 but the problem is present also with RC1. I followed the steps of brando's answer here.
After bundling my application and initial load of the website SystemJS throws error:
Error: http://localhost:57462/app/app.bundle.js detected as register but didn't execute.
The application works but the error in the console definitely is not a good thing.
I tested my configuration on empty project and the problem is present again so I think the problem is in the configuration.
Here it is:
Gulpfile
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',
defaultExtension: 'js',
format: 'register',
packages: packages,
baseURL: "/",
defaultJSExtensions: true,
transpiler: false,
paths: {
"node_modules*": "node_modules*",
"@angular*": "node_modules/@angular/*"
},
map: {
"@angular": "node_modules/@angular",
"symbol-observable": "node_modules/symbol-observable",
"ng2-translate": "node_modules/ng2-translate",
"es6-shim": "node_modules/es6-shim",
"reflect-metadata": "node_modules/reflect-metadata",
"rxjs": "node_modules/rxjs",
"zone.js": "node_modules/zone.js"
}
});
Have you tried using SystemJS Builder in your bundle:app
gulp task instead of jspm?
Below is a simplified version of how to bundle Tour of Heroes running 2.0.0-rc.1 (source, live example).
gulpfile.js
var gulp = require('gulp');
var sourcemaps = require('gulp-sourcemaps');
var concat = require('gulp-concat');
var typescript = require('gulp-typescript');
var systemjsBuilder = require('systemjs-builder');
// Compile TypeScript app to JS
gulp.task('compile:ts', function () {
return gulp
.src([
"appTS/**/*.ts",
"typings/*.d.ts"
])
.pipe(sourcemaps.init())
.pipe(typescript({
"module": "system",
"moduleResolution": "node",
"outDir": "app",
"target": "ES5"
}))
.pipe(sourcemaps.write('.'))
.pipe(gulp.dest('app'));
});
// Generate systemjs-based bundle (app/app.js)
gulp.task('bundle:app', function() {
var builder = new systemjsBuilder('public', './system.config.js');
return builder.buildStatic('app', 'app/app.js');
});
// Copy and bundle dependencies into one file (vendor/vendors.js)
// system.config.js can also bundled for convenience
gulp.task('bundle:vendor', function () {
return gulp.src([
'node_modules/zone.js/dist/zone.js',
'node_modules/reflect-metadata/Reflect.js',
'node_modules/systemjs/dist/system-polyfills.js',
'node_modules/core-js/client/shim.min.js',
'node_modules/systemjs/dist/system.js',
'system.config.js',
])
.pipe(concat('vendors.js'))
.pipe(gulp.dest('vendor'));
});
// Copy dependencies loaded through SystemJS into dir from node_modules
gulp.task('copy:vendor', function () {
return gulp.src([
'node_modules/rxjs/bundles/Rx.js',
'node_modules/@angular/**/*'
])
.pipe(gulp.dest('vendor'));
});
gulp.task('vendor', ['bundle:vendor', 'copy:vendor']);
gulp.task('app', ['compile:ts', 'bundle:app']);
// Bundle dependencies and app into one file (app.bundle.js)
gulp.task('bundle', ['vendor', 'app'], function () {
return gulp.src([
'app/app.js',
'vendor/vendors.js'
])
.pipe(concat('app.bundle.js'))
.pipe(uglify())
.pipe(gulp.dest('./app'));
});
gulp.task('default', ['bundle']);
system.config.js
var map = {
'app': 'app',
'rxjs': 'vendor/rxjs',
'zonejs': 'vendor/zone.js',
'reflect-metadata': 'vendor/reflect-metadata',
'@angular': 'vendor/@angular'
};
var packages = {
'app': { main: 'main', defaultExtension: 'js' },
'rxjs': { defaultExtension: 'js' },
'zonejs': { main: 'zone', defaultExtension: 'js' },
'reflect-metadata': { main: 'Reflect', defaultExtension: 'js' }
};
var packageNames = [
'@angular/common',
'@angular/compiler',

'@angular/http',
'@angular/platform-browser',
'@angular/platform-browser-dynamic',
'@angular/router',
'@angular/router-deprecated',
'@angular/testing',
'@angular/upgrade',
];
packageNames.forEach(function(pkgName) {
packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
});
System.config({
map: map,
