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); });

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 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;
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?
im trying to create a application with angular 2 ,i using videogular 2,and i install videogular 2 with npm and i check my node_modules and videogular2 exist in directory but when i run my application occur an error :
angular2-polyfills.js:126 GET http://localhost:3000/node_modules/videogular2/core 404 (Not Found)
angular2-polyfills.js:390 Error: Error: XHR error (404 Not Found) loading
and this is my configuration :
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js'
}
},
map: {
'videogular2': './node_modules/videogular2'
}
});
System.import('app/main')
.then(null, console.error.bind(console));
just in case if anybody needs answer
this is what you would need to include in you system.config.js after installing via npm install videogular2
map:{
'videogular2': 'node_modules/videogular2',
},
packages:{
'videogular2':{
main: 'core.js',
defaultExtension:'js'
}
}
Happy coding......
I would add a packages block for videogular2 in the SystemJS configuration:
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js'
},
videogular2: { <-------
defaultExtension: 'js'
}
},
map: {
'videogular2': './node_modules/videogular2'
}
});
System.import('app/main')
.then(null, console.error.bind(console));
I am getting the following errors while running my app:
It seems to be looking for ./app.component, rather than ./app.component.js
Here is my main.ts file:
import { bootstrap } from 'angular2/platform/browser';
import { AppComponent } from './app.component';
bootstrap(AppComponent);
What have I done wrong to configure the dependencies here? NB: If I change the references to import { AppComponent } from './app.component.js';, then the error goes away and I am faced with more of the same errors for other references.
EDIT:
One of the comments has suggested that there might be an issue with my system.config(), which I think sounds very plausible, however, this is and excerpt from my index.html file, which I can't see any issues with?
...
<script>
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js'
}
}
});
System.import('client/dev/main.js')
.then(null, console.error.bind(console));
</script>
...
Your mistake is probably that you have :
<script>
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js'
}
}
});
System.import('client/dev/main.js')
.then(null, console.error.bind(console));
</script>
instead of
<script>
System.config({
packages: {
"client/dev": { // this line changed, here the directory where your generated `js` files are, has to be specified
format: 'register',
defaultExtension: 'js'
}
}
});
System.import('client/dev/main')
.then(null, console.error.bind(console));
</script>
I had exactly the same problem as you when I started ;)
Also the zone error should disappear if you use the newest angular beta build (12).
