How to prepare release version with SystemJS and Gulp?
Solution 1:
You will get " Unexpected anonymous System.register call" because the references are not being loaded in the correct order. I use JSPM to properly build my angular app for production. There are 4 parts to the process.
Part 1: Compile your typescript files
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"));
});
Part 2: Configure config.js (to tell JSPM how to bundle your app):
System.config({
baseURL: "/",
defaultJSExtensions: true,
paths: {
"npm:*": "jspm_packages/npm/*",
"github:*": "jspm_packages/github/*",
"node_modules*": "node_modules/*"
},
map: {
'app': 'app',
'rxjs': 'node_modules/rxjs',
'@angular': 'node_modules/@angular'
},
packages: {
'app': { main: 'bootDesktop.js', defaultExtension: 'js' },
'rxjs': { defaultExtension: 'js' },
'@angular/common': { main: 'index.js', defaultExtension: 'js' },
'@angular/compiler': { main: 'index.js', defaultExtension: 'js' },
'@angular/core': { main: 'index.js', defaultExtension: 'js' },
'@angular/http': { main: 'index.js', defaultExtension: 'js' },
'@angular/platform-browser': { main: 'index.js', defaultExtension: 'js' },
'@angular/platform-browser-dynamic': { main: 'index.js', defaultExtension: 'js' },
'@angular/router': { main: 'index.js', defaultExtension: 'js' },
'@angular/router-deprecated': { main: 'index.js', defaultExtension: 'js' },
'@angular/testing': { main: 'index.js', defaultExtension: 'js' },
'@angular/upgrade': { main: 'index.js', defaultExtension: 'js' }
}
});
Part 3: Use gulp-jspm-build to bundle up your app (I was previously using gulp-jspm but it was causing errors, so I switched to gulp-jspm-build):
var jspm = require('gulp-jspm-build');
gulp.task("jspm_bundle", function () {
return jspm({
bundleOptions: {
minify: true,
mangle: false
},
bundleSfx: true,
bundles: [
{ src: './wwwroot/app/appBoot.js', dst: 'boot.bundle.min.js' }
]
})
.pipe(gulp.dest('./wwwroot/js-temp'));
});
//this will create a file called boot.bundle.min.js
//note I have set jspm to create a self-executing bundle
//I put mangle to false because mangling was causing errors
4: Now concat all your already minified assets:
gulp.task("min:js", ["jspm_bundle"], function () {
//this only concats boot.bundle.min.js
//and dependencies.min.js which has already been minified such as es6-shim.js
var files = [
"./wwwroot/js-temp/dependencies.min.js",
"./wwwroot/js-temp/boot.bundle.min.js"
];
return gulp.src(files)
.pipe(concat("boot.bundle.min.js"))
.pipe(gulp.dest("./wwwroot/js"));
});
Finally, put one nice tidy script reference into your index.html:
<script src="~/js/boot.bundle.min.js"> </script>
UPDATE: Revised config.js to conform to a Angular 2.0-rc.0 appp
UPDATE 2: tsconfig.json looks like this:
{
"compilerOptions": {
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"module": "commonjs",
"moduleResolution": "node",
"noImplicitAny": false,
"noEmitOnError": true,
"removeComments": false,
"sourceMap": true,
"declaration": false,
"noLib": false,
"target": "es5",
"outDir": "wwwroot/app/"
},
"exclude": [
"node_modules",
"wwwroot"
]
}
Solution 2:
You can use SystemJS Builder
as easy as this
var path = require("path");
var Builder = require('systemjs-builder');
// optional constructor options
// sets the baseURL and loads the configuration file
var builder = new Builder('path/to/baseURL', 'path/to/system/config-file.js');
builder
.bundle('local/module.js', 'outfile.js')
.then(function() {
console.log('Build complete');
})
.catch(function(err) {
console.log('Build error');
console.log(err);
});
