Anyone can help this? I am trying to import a leaflet plugin (https://github.com/Leaflet/Leaflet.markercluster) for ionic 2
Here is step which I did:
npm install leaflet.markercluster --save
I added leaflet like this:
import * as L from 'leaflet'; import * as LL from 'leaflet.markercluster';
And using it like this:
var markers = LL.markerClusterGroup();
i got an error TypeError:
WEBPACK_IMPORTED_MODULE_2_leaflet_markercluster.markerClusterGroup is
not a function
Are there any ways to custom webpack to load plugin lib? Thanks
Leaflet.markercluster plugin does not export itself the "standard" / UMD way.
When you import it, it only performs a side effect, i.e. it attaches itself to the L (Leaflet) global namespace. It does not return anything into your default import nor LL variable.
But you should be able to use it as if you had included it the "old school" way (i.e. through a <script> tag):
var mcg = L.markerClusterGroup();
BTW, both Leaflet and Leaflet.markercluster perform side effects, so you would just need to import them this way:
import 'leaflet'; // Creates a global L namespace.
import 'leaflet.markercluster'; // Attaches L.markerClusterGroup to global L.
You need to use type declarations along with the module if you are using a javascript module.
For leaflet.markercluster it should be here.
After
npm install leaflet.markercluster --save
Do:
npm install --save-dev #types/leaflet-markercluster
Also ensure your tsconfig.json has the entry "typeRoots": ["types"],
Now it can be imported in your class.
import * as LL from 'leaflet-markercluster';

Trying to use howler.js (https://github.com/goldfire/howler.js#documentation) in a Controller.
There is no addon for Howler but it exists as a npm package.
I did an npm install and subsequently got an update in package.json like this :
"dependencies": {
"bootswatch": "^4.0.0",
"howler": "^2.0.9",
"npm": "^5.8.0"
}
In the controller I added this import
import {Howl} from 'howler';
But when I try to execute the code I get a runtime error
Could not find module 'howler' imported from 'foo/controllers/bar'
When I do a find for *howl* this is what I find
./node_modules/howler/dist/howler.js
./node_modules/howler/dist/howler.core.min.js
./node_modules/howler/dist/howler.min.js
./node_modules/howler/dist/howler.spatial.min.js
./node_modules/howler/src/howler.core.js
./node_modules/howler/src/plugins/howler.spatial.js
Should my import have a path to these files as part of it ? If so which one ?
Would appreciate some advice about whether there's something obviously wrong in what I've done there.
Emberjs version is 3.0.
Thanks
You can import the howler.js inside your ember-cli-build.js like this
app.import('node_modules/howler/dist/howler.min.js')
Then you can use Howl as global variable inside you ember app.
EDIT: this is actually about any npm package which is not designed to play along with ember. In my case, I tried to make crypto-js work, but it seems to be always the same trouble with any npm package not specially designed for ember cli.
I want to use cryptoJS in my ember app, which I'm currently refactoring with ember cli, but I'm having a lot of trouble importing all the third party packages and libraries I'm already using, like for example cryptoJS.
CryptoJS at least has a package for npm, I don't even want to think about what happens if some of my included libraries don't have a package...
Am I just missing the point in the documentation of ember-cli or is it really not described how to import other npm packages and also how to inlcude non-package libraries properly to keep them under version control and dependency control?
If I follow the description of the crypto-js package manual:
var CryptoJS = require("crypto-js");
console.log(CryptoJS.HmacSHA1("Message", "Key"));
I get and error in my ember build
utils/customauthorizer.js: line 1, col 16, 'require' is not defined.
Thanks for any help on this, I'm very excited about the ember cli project, but importing my existing ember app has been quite painful so far...
EDIT:
Just importing unfortunately does not work.
import CryptoJS from 'crypto-js';
throws during the build

The easiest and recommended answer is to use ember-browserify. (as support for bower packages will be removed in the future.)
This is an example for using the npm package dexie within an Ember CLI app.
Install browserify: npm install ember-browserify --save-dev
Install dexie (or whatever module you need): npm install dexie --save-dev
Import the module like this: import Dexie from 'npm:dexie';
UPDATE (April 2021):
ember-browserify has now been is deprecated in favor of either ember-auto-import or ember-cli-cjs-transform
(see the deprecation warning at the top of ember-browserify)
UPDATE: I got this to work much better and straight forward! Thanks to the comment of #j_mcnally!
Will leave the first answer down there so everyone can see what trouble I was coming from :)
What I did:
bower install crypto-js=svn+http://crypto-js.googlecode.com/svn/#~3.1.2 --save
In my file Brocfile.js I could just do app.import('bower_components/crypto-js/build/rollups/hmac-md5.js');
No manual downloading or moving files, just managing a dependency, much better solution!
But honestly, it was still a lot of vodoo! Until I found the documentation... sweet: http://bower.io/docs/api/#install
OLD approach
I got this to work, but I can not tell how pretty or correct that approach is. Including third party packages or libraries with ember cli is pretty far away from straight forward or self explaining.
The ressources which led me to my working solution were:
how to use third party javascript from ember-cli route
https://github.com/stefanpenner/ember-cli/issues/757
The following steps I took to get it working:
I manually downloaded the library https://code.google.com/p/crypto-js/downloads/detail?name=CryptoJS%20v3.1.2.zip and unziped it
I manually created a directory in my vendor directory: mkdir vendor/crypto-js
I appended app.import('vendor/crypto-js/hmac-md5.js'); to the Brocfile.js file
I added "CryptoJS" to the "predef" key in the .jshintrc file
Then the build worked and I could eventually use the library.
Sadly I didn't get the npm package to work! I had to manually download the zip file, unzip it and move it to the correct location and if the version changes, it's not under any version/dependency control... I will not mark this as an answer, since it does not satisfy me at all, but at least I wanted to share what I did to make it work for me.
As Timm describes, using browserify gets the code injected into your ember app. However, I was having trouble actually using the injected module. In order to do that I had to actually create the module with New before I could use it:
In order to import an NPM module.
1) install browserify:
npm install ember-browserify --save-dev
2) install your modele:
npm install my-module --save-dev
3) Import your module into your ember file of interest (app/controller/post.js):
import Module from 'npm:my-module';
4) use the module from within your code by creating the module with New:
var output = new Module(var1, var2, etc.);
even though this is an old thread thought I would contribute as I spent a while doing this. The specific package I was trying to link to ember was 'd3plus' and had to do a variety of things to get it to work.
npm install ember-browserify --save-dev
npm install d3plus --save-dev
ember install ember-cli-coffeescript
npm install --save-dev coffeeify coffeescript
then in your component do
import d3plus from 'npm:d3plus';
For a long time I was getting runtime errors when it was searching for the coffescript and figured this would be helpful for people specifically looking for d3plus.
As stated by Pablo Morra on a comment of the simplabs' post "Using npm libraries in Ember CLI", third party npm modules can be imported on Ember.js from version 2.15 directly without the need of addons or wrappers:
https://www.emberjs.com/blog/2017/09/01/ember-2-15-released.html#toc_app-import-files-within-node_modules
Unfortunately documentation is still on work and it doesn't say that npm modules can be imported, only bower and vendor ones:
https://github.com/emberjs/guides/issues/2017
https://guides.emberjs.com/v3.0.0/addons-and-dependencies/managing-dependencies/
I've gotten 2 solutions to import third party npm modules directly on Ember.js from the Ember CLI documentation about managing dependencies, although it's also out-of-date and says that npm modules can't be imported, only bower and vendor ones:
npm module as Standard Anonymous AMD Asset
https://ember-cli.com/managing-dependencies#standard-anonymous-amd-asset
AMD: Asynchronous Module Definition
I prefer and use this way because it avoids global variables and follows the import convention of Ember.js.
ember-cli-build.js:
app.import('node_modules/ic-ajax/dist/amd/main.js', {
using: [
{ transformation: 'amd', as: 'ic-ajax' }
]
});
amd is the type of transformation applied, and ic-ajax is the module name to be used when it's imported on a javascript file.
on Ember.js javascript file (router, component...):
import raw from 'ic-ajax';
// ...
icAjaxRaw( /* ... */ );
raw is a module exported by ic-ajax.
That's the way it worked for me although the Ember CLI documentation shows the import other way that didn't work for me, maybe because of the specific package I was importing:
import { raw as icAjaxRaw } from 'ic-ajax';
//...
icAjaxRaw( /* ... */ );
npm module as global variable
https://ember-cli.com/managing-dependencies#standard-non-amd-asset
ember-cli-build.js:
app.import('node_modules/moment/moment.js');
on Ember.js javascript file (router, component...):
/* global moment */
// No import for moment, it's a global called `moment`
// ...
var day = moment('Dec 25, 1995');
/* global moment */ is an annotation for ESLint not to show an error when building the project because moment() is not defined in the file.
npm module as Standard Named AMD Asset
https://ember-cli.com/managing-dependencies#standard-named-amd-asset
Ember CLI also shows a third option that didn't work for me, maybe because of the specific package I was importing:
ember-cli-build.js:
app.import('node_modules/ic-ajax/dist/named-amd/main.js');
on Ember.js javascript file (router, component...):
import { raw as icAjaxRaw } from 'ic-ajax';
//...
icAjaxRaw( /* ... */ );
npm module as AMD JavaScript modules
https://guides.emberjs.com/v3.0.0/addons-and-dependencies/managing-dependencies/#toc_amd-javascript-modules
The way described on Ember.js documentation about Managing Dependencies didn't work for me either, maybe because of the specific package I was importing:
ember-cli-build.js:
app.import('node_modules/ic-ajax/dist/named-amd/main.js', {
exports: {
'ic-ajax': [
'default',
'defineFixture',
'lookupFixture',
'raw',
'request'
]
}
});
on Ember.js javascript file (router, component...):
import { raw as icAjaxRaw } from 'ic-ajax';
//...
icAjaxRaw( /* ... */ );
I just started working with Ember-CLI 0.0.36 and I'm stuck with the Gravatar example code from the Ember.js homepage.
I did
> bower install --save JavaScript-MD5
> ember generate component gravatar-image
Brocfile.js
[...]
app.import('vendor/JavaScript-MD5/js/md5.js');
[...]
app/components/gravatar-image.js
import Ember from 'ember';
export default Ember.Component.extend({
size: 200,
email: '',
gravatarUrl: function() {
var email = this.get('email'),
size = this.get('size');
return 'http://www.gravatar.com/avatar/' + md5(email) + '?s=' + size;
}.property('email', 'size')
});
After starting ember server I'll get the following error message:
xyz/components/gravatar-image.js: line 11, col 48, 'md5' is not defined.
1 error
How can I tell the component to use JavaScript-MD5?
To get this to work I used:
bower install blueimp-md5 --save-dev
and added import in Brocfile.js
app.import('bower_components/blueimp-md5/js/md5.js');
then add "md5" to predef array as mentioned by Oliver to suppress md5 warning.
JavaScript-MD5 does't export any AMD-Modules, if I see it right. But it defines window.md5. So your app.import will include it in vendor.js and you can call window.md5 in the component.
That's just a jshint linter message.
Open your .jshintrc file, add "md5" to the "predef" object and you are fine.
You might need to install the ember-cli-md5 package. This will install all the required dependencies in your node modules.
Use this npm install --save-dev ember-cli-md5 to install ember-cli-md5.
Once installed you will need to generate md-5 which will install the browser package via bower.
Use this to generate md-5 ember generate md-5.
So, you need to perform following two steps:-
npm install --save-dev ember-cli-md5
ember generate md-5
Since ember-cli 0.0.34 jquery is removed from the .jshint file as predefined.
So jquery needs to be imported, but I get the following error when doing it:
import $ from 'jquery';
The error I get is:
ENOENT, no such file or directory 'S:\...\tmp\tree_merger-tmp_dest_dir-Nb27WzDk.tmp\jquery.js'
Error: ENOENT, no such file or directory 'S:\...\tmp\tree_merger-tmp_dest_dir-Nb27WzDk.tmp\jquery.js'
at Object.fs.statSync (fs.js:684:18)
at addModule (S:\...\node_modules\ember-cli\node_modules\broccoli-es6-concatenator\index.js:81:46)
.....
I solved the problem by not importing jquery at all. jQuery is available via Ember.$ (link)
So I changed my code to use Ember.$(...) instead of $(...)
I've ran into the same problem after I updated ember-cli to 0.0.34. Although I was still able to use $ (jQuery) in my code, JSHint kept throwing the error:
project/views/blah.js: line 6, col 9, '$' is not defined.
You can edit your .jshintrc and add $ back to predef.
{
"predef": {
// ...
"$": true,
// ...
},
// ...
}
Would definitely prefer a method using import too.
Not sure if this will be of any help, but I was able to locate the file during build by using the line below, but it caused some issues in the browser:
import $ from 'vendor/jquery/dist/jquery';
$ becomes available after rendering / instantiation, as per usual use of jQuery.
If jQuery is desired to be used otherwise is requires the Ember prefix.
Handlebars is likewise available as Ember.Handlebars, albeit the Ember extended version.
I solved the problem by adding this code to my JS file
import jQuery from 'ember';
Newer versions of Ember/Ember-CLI allow for destructuring, making importing libraries much easier.
import Ember from 'ember';
const { $, get, set } = Ember;
Would bring in jquery, getters and setters.
Make sure you've listed #ember/jquery in your dependencies within package.json of the consumed app/addon. It might look something like this:
"#ember/jquery": "^1.1.0"
Then you can continue to use jquery in the recommended way:
import $ from 'jquery';
I'm trying to import ic-modal into an ember-cli project, but for some reason I keep getting this error:
Uncaught Error: <ic-test#view:toplevel::ember278> Handlebars error: Could not find property 'ic-modal-trigger' on object (generated application controller).
I have the following import statements:
app.import('vendor/ic-styled/main.js');
app.import('vendor/ic-modal/dist/named-amd/main.js', {
'ic-modal': [
'ModalComponent',
'ModalFormComponent',
'ModalTriggerComponent',
'ModalTitleComponent',
'modalCss'
]
});
Any help with this would be great?!
In Brocfile.js:
app.import('bower_components/ic-styled/main.js');
app.import('bower_components/ic-modal/dist/named-amd/main.js');
Replace bower_components with vendor in the above if you're still using an older version of Ember-CLI.
Then use:
import ICModal from 'ic-modal';
// Can now utilise ICModal, ICModal.ModalForm etc
The Broccoli build and ES6 module transpiler should take care of the rest.
(Side-note: when using Coffeescript, put the import statement in backticks as the standard Coffeescript compiler doesn't handle the ES6 syntax.)
