Import jquery with SystemJS doesn't work

I can't figure out how to import jQuery with SystemJS in a way that it works into my project.
index.html:
...
<script>
System.import('app').catch(function(err){ console.error(err); });
System.import('jquery').catch(function(err){ console.error(err); });
System.import('bootstrap').catch(function(err){ console.error(err); });
</script>
...
error:
(index):26 Error: (SystemJS) Bootstrap's JavaScript requires jQuery
Error: Bootstrap's JavaScript requires jQuery
at eval
systemjs.config.js
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
...
'jquery': "npm:jquery/dist/jquery.min.js",
'bootstrap': "npm:bootstrap/dist/js/bootstrap.min.js",
// other libraries
'rxjs': 'npm:rxjs'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
}
}
});
})(this);

This is happening because bootstrap is importing first.
The imports are asynchronous. One may import before the other. To force order:
System.import('jquery')
.then(function($) {
System.import('bootstrap');
})
.catch(function(err){ console.error(err); });

How to include zone.js, reflect-metadata etc. in Systemjs builder task?

I'm using system.js and systemjs builder to create a dist folder with all the packed javascript files of my angular2 application.
It works pretty nicely, except that it does not include the following files, which are currently statically included in the index.html:
node_modules/zone.js/dist/zone.js
node_modules/reflect-metadata/Reflect.js
node_modules/systemjs/dist/system.src.js
node_modules/esri-system-js/dist/esriSystem.js
How can I force systemjs builder to include these dependencies?
libs-bundle.js:
var SystemBuilder = require('systemjs-builder');
var builder = new SystemBuilder();
builder.loadConfig('./systemjs.config.js').then(function() {
return builder.bundle(
'app - [app/**/*]', // build app and remove the app code - this leaves only 3rd party dependencies
'dist/libs-bundle.js'
);
}).then(function() {
console.log('library bundles built successfully!');
});
app-bundle.js
var SystemBuilder = require('systemjs-builder');
var builder = new SystemBuilder();
builder.loadConfig('./systemjs.config.js').then(function() {
return builder.bundle(
'app - dist/libs-bundle.js', // build the app only, exclude everything already included in dependencies
'dist/app-bundle.js'
);
}).then(function() {
console.log('Application bundles built successfully!');
});
systemjs.config.js:

I would try doing an npm install in your app directory for each of the missing packages
npm i zone.js
npm i reflect-js
npm i systemjs
npm i esri-system-js

There are a few thing you should do:
set the saveDependenciesAsComponents in your bit.json file. Look here.
When you do bit import, to bring your components, do bit import --skip-npm-install in order to avoid the component package dependencies. This will fallback to the project dependencies due to node module resolution.

I'm not familiar with the library, but if you're in a node runtime, then would something like this work?
const fs = require('fs');
// File destination.txt will be created or overwritten by default.
fs.copyFile('source.txt', 'destination.txt', (err) => {
if (err) throw err;
console.log('source.txt was copied to destination.txt');
});
source
P.S. I recommend fs-jetpack or some other third party wrapper around fs, but this is the simplest snippet to copy a file from one location to another.

ng2-translate (404 not found) I've added it in system.js

I've installed ng2-translate to my proj and console error keep showing 404 of the bundle and xhr error. I've added ng2-translate to my system.config.js that comes with the standard angular2 quickstart but still showing 404 and xhr error.
It's either giving me 404 error or annotation of undefined error :/
github: thread regarding the issue using systemconfig.js
https://github.com/ocombe/ng2-translate/issues/167
var map = {
'app': 'app', // 'dist',
'#angular': 'node_modules/#angular',
'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
'ng2-translate': 'node_modules/ng2-translate',
'rxjs': 'node_modules/rxjs'
};
Edit:
var packages = {
'ng2-translate': { main: 'ng2-translate.js', defaultExtension: 'js' },
};

I faced to the same issue today
solution is this:
put 'ng2-translate': 'node_modules/ng2-translate/bundles' in system.config.js in the map and 'ng2-translate' : { defaultExtension: 'js' } in packages

I had to map it like this, in the systemjs config to make it work:
'ng2-translate': 'npm:ng2-translate/bundles/ng2-translate.umd.js'

install the npm module:
npm install ng2-translate --save
update your config like this:
System.config({
packages: {
"ng2-translate": {main: 'ng2-translate.js', "defaultExtension": "js"}
},
map: {
'ng2-translate': 'node_modules/ng2-translate'
}
});
Use ng2-translate like this in .ts file-
import {TranslateService, TranslatePipe} from 'ng2-translate';
See if this helps.

Probably by doing:
'ng2-translate': 'node_modules/ng2-translate',
you are referring index.js
however you might need to point some else .js file such as
'ng2-translate': 'node_modules/ng2-translate/somefile.js',
for example you can do:
System.config({
//... some other stuff
map: {
'ng2-translate': 'node_modules/ng2-translate/ng2-translate.js',
},
packages: {
//... some other stuff, do not put your ng2-translate here
}
});

ng2-translate uses the CommonJS module format as configured in its tsconfig.json:
compilerOptions": {
...
"module": "commonjs",
"target": "es5",
...
}
I successfully added ng2-translate by explicitly specifying this format in the packages section of my SystemJS config.
System.config({
map: {
'ng2-translate': 'node_modules/ng2-translate'
// ... more mappings
},
packages: {
'ng2-bootstrap': {
defaultExtension: 'js',
format: 'cjs'
}
// ... more package definitions
}
});
Refer to the list of supported module formats in the SystemJS documentation for more details.

If like me, you've spent hours trying to fix the ng2-translate (404 not found) issue. Here's is a systemjs.config.js which worked for me. Compliment of Sam Verschueren #github
(function(global) {
// map tells the System loader where to look for things
var map = {
'app': 'app', // 'dist',
'#angular': 'node_modules/#angular',
'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
'rxjs': 'node_modules/rxjs'
};
var paths = {
'underscore': 'node_modules/underscore/underscore.js',
'ng2-translate': 'node_modules/ng2-translate/bundles/ng2-translate.umd.js'
};
// packages tells the System loader how to load when no filename and/or no extension
var packages = {
'app': { main: 'main.js', defaultExtension: 'js' },
'rxjs': { defaultExtension: 'js' },
'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
'ng2-translate': { defaultExtension: 'js' }
};
var ngPackageNames = [
'common',
'compiler',
'core',
'forms',
'http',
'platform-browser',
'platform-browser-dynamic',
'router',
'router-deprecated',
'upgrade',
];
// Individual files (~300 requests):
function packIndex(pkgName) {
packages['#angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
}
// Bundled (~40 requests):
function packUmd(pkgName) {
packages['#angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
}
// Most environments should use UMD; some (Karma) need the individual index files
var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
// Add package entries for angular packages
ngPackageNames.forEach(setPackageConfig);
var config = {
map: map,
packages: packages,
paths: paths
};
System.config(config);
})(this);

you need to have a i18n folder in your app with en.json (its the default setting) or whatever file you call from the constructor, looks like:
constructor(translate: TranslateService) {
// this language will be used as a fallback when a translation isn't found in the current language
translate.setDefaultLang('en');
// the lang to use, if the lang isn't available, it will use the current loader to get them
translate.use('en');
}

How do I include a javascript library with angular 2?

How do I use a javascript library with angular 2? I always get an error saying it's not a module.
If I add a script tag to my index.html file pointing to the javascript file, then add it under paths under System.config, then import it, I get an error stating that it's not a module.
I've already tried this and I've also tried this. Neither of them work despite the fact they seem to like to point out that it's easy, and that you can use any of hundreds of libraries.
Here is a javascript library: sheetjs
How do I make this work in angular 2?

include it in the map variable in this.
add 'xlsx': { defaultExtension: 'js' }, to packages variable. then in your index.html add after the

Maybe this helps:
I noticed, that you are trying to implement the sheetjs/xlsx library. There is a working XLSX library for typescript available here, which works with angular2!
If you are looking for a working demo, have a look here.

You dont included your index.html content, but I assume that the
<script src="../node_modules/xlsx/xlsx.js" type="text/javascript"></script> tag is imported before your base component . If that is true then try to import the script after the base component and on typescript use: declare var xlsx:any;

AngularJS 2 seed + System.JS - New .ts file doesn't compile

I pulled the latest angularjs2 seed application from github (https://github.com/angular/angular2-seed) and got it running in webstorm.
Now I wanted to add a simple load.ts file which preloads some components:
declare var System: any;
declare var esriSystem: any;
esriSystem.register([
'esri/geometry/Point',
'esri/geometry/geometryEngineAsync',
'esri/Map'
], function() {
// bootstrap the app
System.import('../app')
.then(null, console.error.bind(console));
}, {
outModuleName: 'esri-mods'
});
I would like to use this module inside a new map.service.ts: import { Map } from 'esri-mods'; it tells me that it cannot resolve file 'esri-mods'
The overall structure looks like this:
And the system.config.js as follows:
System.config({
transpiler: 'typescript',
typescriptOptions: {
emitDecoratorMetadata: true
},
map: {
app: 'src',
typescript: 'node_modules/typescript/lib/typescript.js',
angular2: 'node_modules/angular2',
rxjs: 'node_modules/rxjs'
},
packages: {
app: {
defaultExtension: 'ts',
main: 'app.ts'
},
angular2: {
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
}
}
});
What is missing for the module to be usable within the application?
