The Sugar Learning Platform is a leading learning platform that began in the famous One Laptop Per Child project. It is used every day by nearly 3 million children around the world.
Sugarizer is a web implementation of the platform and runs on every device - from tiny Raspberry Pi computers to small Android and iOS phones to tablets and to laptops and desktops. It has 3 broad components:
- Web Application: a web application that runs in modern web browsers
- Application: an installable app for every operating system
- Server: a nodejs/express server for applications to connect with
Enjoy the experience and help us reach every child on every device in every country.

Sugarizer Web App is a web application that runs on any device with a recent Chrome version and has also been tested successfully on Firefox, Safari, EDGE and IE.
Features include:
- No installation required
- Runs any Sugar Web Activity available from a Sugarizer Server
- Sugar Home view (Radial and List)
- Sugar Journal
- Sugar Local Data Store (limited by the browser to 5Mb, learn more)
- Backup locally stored content to the Server
- Share locally stored content through the Server
- Sugar Presence
- Sugar Collaboration
As a web application, it does not run offline and requires a permanent network connection to a Sugarizer Server.
Each Sugarizer Server provides its own copy of the Web Application.
Sugarizer Application is a cross-platform application for installing on any GNU+Linux, Windows, Mac OS X, Android, iOS, or Chrome OS device.
Features are the same as Web Application, plus:
- Runs completely offline, without accessing any server
- Some features (like collaboration) do a require network connection
To run Sugarizer Application on Android, download it on Google Play, Amazon Store or F-Droid. You could also build yourself the Sugarizer Application APK using instruction below.
To run Sugarizer Application on iOS, download it on Apple Store or build yourself the Sugarizer Application IPA using instructions below.
To run Sugarizer Application on Windows 10, download it on Windows Store. You could also build yourself the Sugarizer Windows Application using instructions below.
To run Sugarizer Application as Chrome Web App, download it from the Chrome Web Store or use the Chrome Apps & Extensions Developer Tool and use the Sugarizer directory as the target for the unpacked application.
To run Sugarizer Application from the Web Browser (GNU Linux/Mac OS/Windows), close any running instances of Chrome and re-launch it using the command line:
chrome --allow-file-access-from-files index.html
The option --allow-file-access-from-files is needed to enable access to local files.
Equivalent options for other browser are available.
If you run Sugarizer this way often, you should create an alias for this command (learn more).
Sugarizer Server is the back-end for network features of Sugarizer. It means: allow deployment of Sugarizer on a local server, for example on a school server, so expose locally Web Application (without Internet access). Sugarizer Server can also be used to provide collaboration features for Application and Web Application on the network. Sugarizer Server could be deployed on any computer with Apache2, Node.js and MongoDB, or in a Docker container.
Sugarizer Server features include:
- Sugarizer Web Application access,
- Backup and shared storage for Application and Web Application,
- Presence and collaboration handling between Application/Web Application on the same network
##Running the server using Docker
To run your own Sugarizer Server with a few command lines using Docker and Docker Compose:
Install Docker and Docker Compose on Ubuntu
curl -fsSL https://get.docker.com/ | sh
Install Docker Compose
curl -L "https://github.com/docker/compose/releases/download/1.8.1/docker-compose-$(uname -s)-$(uname -m)" > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
To install Docker Compose on ARM architectures (e.g. for the Raspberry Pi 3), the link above will not work. You need to use arm-compose instead.
You can find more details about the installation of Docker here
You can find more details about the installation of Docker Compose here
After that, go to the sugarizer folder and launch
sh generate-docker-compose.sh
docker-compose up -d
Your Sugarizer server will start automatically and will be accessible on http://127.0.0.1 and your public IP. The database will be persisted inside the folder docker/db
##Running the server using the classic way
To run your own Sugarizer Server without Docker, follow the step behind. Commands are shown from a new Debian Linux machine and could be different for other platforms or for an already installed machine:
Install Apache2: you need to install Apache2 and ensure than few mods are available and enabled: mod_headers, mod_proxy, mod_proxy_http and mode_rewrite. You need also to allow override on /var/www directory. See here for more.
sudo apt-get install apache2
cd /etc/apache2/mods-enabled
sudo ln -s ../mods-available/headers.load headers.load
sudo ln -s ../mods-available/rewrite.load rewrite.load
sudo ln -s ../mods-available/proxy.load proxy.load
sudo ln -s ../mods-available/proxy_http.load proxy_http.load
sudo vi /etc/apache2/sites-available/default # Set to all value for /var/www AllowOverride
sudo /etc/init.d/apache2 restart
Install Node.js: Install Node.js and npm to manage packages. See here more information.
sudo apt-get install nodejs
Install MongoDB: Don't forget to create a /data/db directory to store databases. See here more information.
sudo apt-get install mongodb
sudo mkdir -p /data/db
Install Sugarizer: If need, you could update server/sugarizer.ini file (update port for web, mongodb or presence)
sudo apt-get install git
cd /var/www
sudo git clone https://github.com/llaske/sugarizer
cd /var/www/sugarizer/server
sudo npm install
Run MongoDB and Sugarizer Server:Run mongo daemon and Sugarizer a background process.
sudo mongod --fork --port 27018 --logpath /home/root/mongo.log
sudo nohup node sugarizer.js > /home/root/sugarizer.log &
Update Firewall rules: If need, open Firewall port for HTTP and Presence.
sudo iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT # HTTP
sudo iptables -A INPUT -i eth0 -p tcp --dport 8039 -j ACCEPT # Presence
sudo iptables -A OUTPUT -p tcp --dport 8039 -j ACCEPT # Presence
Check your install: To check your install, run "http://<server name>/sugarizer" in your browser:
- you should see the home with all activities,
- go to Journal view, you should see at the bottom of the screen the two icons to switch to private/shared journal,
- go to the neighborhood view, you should see one icon for the server and one for you.
You could also run unit tests (see below) to ensure that everything works.
Server settings
If needed, Sugarizer server settings could be changed using the sugarizer.ini config file (you could use another name for this file: just pass the new name as sugarizer.js parameter).
[web]
port = 8080
[presence]
port = 8039
[database]
server = localhost
port = 27018
name = sugarizer
[collections]
users = users
journal = journal
[activities]
activities_directory_name = activities
activities_path = ../activities
template_directory_name = ActivityTemplate
activity_info_path = activity/activity.info
favorites = org.sugarlabs.GearsActivity,org.sugarlabs.MazeWebActivity,org.olpcfrance.PaintActivity,org.olpcfrance.TamTamMicro,org.olpcfrance.MemorizeActivity,org.olpg-france.physicsjs,org.sugarlabs.CalculateActivity,org.sugarlabs.TurtleBlocksJS,org.sugarlabs.Clock,,org.olpcfrance.RecordActivity,org.olpcfrance.Abecedarium,org.olpcfrance.KAView,org.olpcfrance.FoodChain,org.olpc-france.labyrinthjs,org.olpcfrance.TankOp,org.sugarlabs.ChatPrototype,org.olpcfrance.Gridpaint,org.olpc-france.LOLActivity,org.sugarlabs.StopwatchActivity,org.sugarlabs.GTDActivity,org.sugarlabs.Markdown,org.laptop.WelcomeWebActivity
The [web] section describe the settings of the node.js process. Sugarizer server uses an Apache web server and a node.js web server. The Apache Web server redirect calls to the node.js server. The link between them is set in the file api/.htaccess.
RewriteEngine on
# Redirect a whole subdirectory:
RewriteRule ^(.+) http://localhost:8080/$1 [P]
So by default, the Apache Web server expects that the node.js server listens on port 8080. You have to change both this file and the port value in the web section to change the port.
The [presence] section describe the settings of the presence server. By default, a web socket is created on port 8039. You need to change this value if you want to use another port. Warning: presence.js in activities hardcode this port today.
The [database] and [collections] sections are for MongoDB settings. You could update the server name (by default MongoDB run locally) and the server port. Names of the database and collections had no reason to be changed.
The [activities] section describe information on where to find embedded activities. The favorites value list ids of activities that Web Application users will find by default on the home page. All values are self explained and had no reason to be changed.
Server API
Sugarizer Server exposes a REST API used by applications to handle collaboration.
// Activities API
[GET] /api/activities
[GET] /api/activities/:id
// Users API
[GET] /api/users
[GET] /api/users/:uid
[POST] /api/users
[PUT] /api/users/:uid
// Journal API
[GET] /api/journal/shared
[GET] /api/journal/:jid
[GET] /api/journal/:jid/filter/:aid
[GET] /api/journal/:jid/field/:field
[GET] /api/journal/:jid/filter/:aid/field/:field
[POST] /api/journal/:jid
[GET] /api/journal/:jid/:oid
[PUT] /api/journal/:jid/:oid
[DELETE] /api/journal/:jid/:oid
A full documentation of the API is available in server/doc or online on http://sugarizer.org/apidoc/.
Sugarizer includes a bunch of pedagogic activities. All activities could be found in the activities directory. Each activity has its own subdirectory. So for example, the Abecedarium activity is located in activities/Abecedarium.activity
You could distribute Sugarizer with whatever activities you want. To do that, you first need to adapt the content of the activities directory to match your wish: removing activities you don't want to distribute and adding in this directory new activities you want to include.
Then you need to update the activities.json file to reflect your choice. Here an example of this file:

Each line in this file is one activity. Here is the description of each field:
- id: Activity unique ID
- name: Display name of the activity
- version: Activity version number
- directory: Location directory of the activity in Sugarizer
- icon: Location of the icon in the activity directory
- favorite: true means that the activity is in the favorite view
- activityId Reserved for internal use
Remove in this file rows for activities that you want to remove. Add in this file a line for each activity you want to add.
Note than:
- The activities/ActivityTemplate directory does not contain a real activity. It's just a template that you could use to create your own activity.
- The activities.json is used only by Sugarizer Application, the Web Application relies on the /api/activities API that dynamically browse the activities directory. By the way, it's a good practice to match the content of the activities.json file and the content of the activities directory.
With Sugarizer, it's easy to create your own activity with a bunch of HTML and JavaScript. Here's the step to follow.
See a video tutorial here.
First, copy all content of activities/ActivityTemplate directory in a new directory for example activities/MyActivity.activity.
Then customize the activity. Choose a name for your activity. Write it in the activity name and bundle_id properties in activity/activity.info of the new directory.
[Activity]
name = My Activity
activity_version = 1
bundle_id = org.sugarlabs.MyActivity
exec = sugar-activity-web
icon = activity-icon
Change also the title tag of index.html.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>My Activity</title>
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width"/>
<link rel="stylesheet" media="not screen and (device-width: 1200px) and (device-height: 900px)"
href="lib/sugar-web/graphics/css/sugar-96dpi.css">
<link rel="stylesheet" media="screen and (device-width: 1200px) and (device-height: 900px)"
href="lib/sugar-web/graphics/css/sugar-200dpi.css">
<link rel="stylesheet" href="css/activity.css">
<script data-main="js/loader" src="lib/require.js"></script>
</head>
Update the file activities.json of the Sugarizer directory: add a new line for your activity. Update id, name and directory values on this new line.
[
{"id": "org.sugarlabs.MyActivity", "name": "My Activity", "version": 1, "directory": "activities/MyActivity.activity", "icon": "activity/activity-icon.svg", "favorite": true, "activityId": null},
{"id": "org.sugarlabs.GearsActivity", "name": "Gears", "version": 6, "directory": "activities/Gears.activity", "icon": "activity/activity-icon.svg", "favorite": true, "activityId": null},
{"id": "org.sugarlabs.MazeWebActivity", "name": "Maze Web", "version": 2, "directory": "activities/MazeWeb.activity", "icon": "activity/activity-icon.svg", "favorite": true, "activityId": null},
Now run Sugarizer, you should see the icon of your new activity. Let's run it!
In your new activity, you will find the following file structure:
my-activity/
|-- activity/
| |-- activity.info
| `-- activity-icon.svg
|-- index.html
|-- css/
| `-- activity.css
|-- js/
| |-- activity.js
| `-- loader.js
|-- lib/
|-- package.json
`-- setup.py
activity/contains information about your activity, including the name, ID, and the icon.index.htmlis where the elements that compose your activity are defined. The template comes with a toolbar and a canvas where you can place your content.js/activity.jsis where the logic of your activity lives.css/activity.cssis where you add the styling of your activity.
Those are the files you'll modify in most cases. The others are:
js/loader.jsconfigures the libraries paths and loads yourjs/activity.jslib/contains the librariespackage.jsoncontains information about the libraries the activity depends onsetup.pyis used if you want to run your activity in Sugar.
Now you are ready to go ahead and develop your activity in the HTML, JavaScript and CSS files.
This simple example will show you how web activities are structured as bits of HTML, CSS and JavaScript.
You will need an SVG graphic for the button. Or you can use one from the Sugar icon set at lib/sugar-web/graphics/icons/. For this example, let's say you have one custom icon called my-button.svg.
Create a directory icons/ inside your activity and place the SVG
file inside. Then do the following steps.
In index.html, add a new <button> element inside the toolbar:
<button class="toolbutton" id="my-button" title="My Button"></button>
In css/activity.css, define the button style:
#main-toolbar #my-button {
background-image: url(../icons/my-button.svg);
}
In js/activity.js, add a callback for the button:
var myButton = document.getElementById("my-button");
myButton.onclick = function () {
console.log("You clicked me!");
}
Soon you will find that adding content to the HTML as we did with the toolbar button in the previous section, is very limited. You'll want to add HTML elements on the fly, as the user interacts with the activity, or as the data structures of your activity logic change. There are several options to archive this. Most of the time you'll end using a mix of them, so is important to know them all.
First, it is possible to create HTML elements and append them to other HTML elements using JavaScript. This is called "manipulating the DOM".
Add this in js/activity.js:
var canvas = document.getElementById("canvas");
canvas.innerHTML +=
'<ul id="names-list">' +
'<li class="name">Tom</li>' +
'<li class="name">Chris</li>' +
'<li class="name">Donald</li>' +
'</ul>';
Run again your new activity, you will see then change.
That's all, it's your turn now to transform this activity in something fun!
See Sugar Web Samples for more samples using the Sugar unique UI.
Sugarizer includes a set of unit tests both for application side and for server side. To run unit tests, you should first install Mocha:
sudo npm install -g mocha
To run unit tests for Sugarizer Server, launch:
cd server
mocha --delay
Note that settings for unit testing are defined in server/test.ini. To run unit tests for Sugarizer Application, run "file:///PathToYourSugarizerRepo/test/index.html" in your browser.
This is not needed with Docker Compose.
Instead of running your Sugarizer Server like described in the "Run MongoDB and Sugarizer Server" section above, you could use a tool like supervisor to run it in background.
First install, supervisor:
sudo apt-get install supervisor
Then install the wait-for-mongo node tool:
sudo npm install -g wait-for-mongo
Create a sugarizer.sh file in /home/root directory:
wait-for-mongo mongodb://127.0.0.1:27018/sugarizer 30000
cd /var/www/server
node sugarizer.js
Create a sugarizer.conf setting file in /etc/supervisor/conf.d directory:
[supervisord]
nodaemon=true
[program:mongod]
command=/usr/bin/mongod --port 27018 --logpath /home/root/mongo.log
priority=1
[program:sugarizer]
command=sh /home/root/sugarizer.sh
priority=2
stdout_logfile=/home/root/sugarizer.log
stderr_logfile=/home/root/sugarizer.log
autostart=true
autorestart=true
Run the supervisor daemon for the first time:
sudo /etc/init.d/supervisor start
MongoDB and Sugarizer Server should now start automatically at startup and restart if fail. You could start it manually using:
sudo supervisorctl start sugarizer
You could end it manually using:
sudo supervisorctl stop sugarizer
Sugarizer Application could be packaged as an Android, iOS and Windows 10 application using Cordova.
To build it, first install Cordova as described here.
Then create a directory for Sugarizer Cordova and put the content of the git repository in the www directory:
cordova create sugar-cordova
cd sugar-cordova
rm config.xml
rm -fr www
git clone https://github.com/llaske/sugarizer.git www
Add the platform you want to add (here Android):
cordova platform add android
Replace the auto generated config.xml file by the Sugarizer one:
cp www/config.xml .
Build the package:
cordova build android
On Android, if you want to generate the Sugarizer OS version, remove the SugarizerOS comment around the cordova-plugin-sugarizeros plugin in config.xml file.
The current size of Sugarizer is about 300 Mb. This huge size is related to media content and resources include in two activities:
- Abecedarium activity: about 150 Mb
- Etoys activity: about 100 Mb
By the way, both activities are able to retrieve the content remotely if its not deployed locally. So, if you want to reduce the Sugarizer package size (specifically for deployment on mobile) you could either remove completely those two activities or just remove the media content of this activities.
To remove activities, just remove both activities directory and update activities.json file as explain above.
To remove media content for Abecedarium, remove directories:
- activities/Abecedarium.activity/audio/en
- activities/Abecedarium.activity/audio/fr
- activities/Abecedarium.activity/audio/es
- activities/Abecedarium.activity/images/database
The activity will look for media content on the server referenced in activities/Abecedarium.activity/config.js, by default http://server.sugarizer.org/activities/Abecedarium.activity/.
To remove resources for Etoys, remove directory activities/Etoys.activities/resources and replace the value resources/etoys.image in activities/Etoys.activities/index.html by the remote location of the resources, for example http://server.sugarizer.org/activities/Etoys.activity/resources/etoys.image.
If you want to optimize JavaScript performance, you could generate an optimized version of Sugarizer with Grunt. This optimized version will minimize and reduce size of all JavaScript files.
The Gruntfile.js contains tasks settings to build an optimized version of Sugarizer. To do that, ensure first that grunt is installed:
npm install -g grunt-cli
Then just launch:
grunt
At the end of the process, the build directory will contain the optimized version of each file in a same directory that the initial one, so you could just copy files:
cp -r build/* .
Sugarizer use webL10n localization system by Fabien Cazenave.
Here how to add a new translation. See a video tutorial here.
All strings are localized in the locale.ini file at the root of the repository. If you want to add a new translation, copy the whole [en] section at the end of the file and:
-
Replace "en" by the ISO 639-1 code of your language. For example, "fr" for French,
-
Substitute the right side of the "=" character on each line by the string localized in your language. For example:
[fr] StartNew=Commencer un nouveau NameActivity=Activité {{name}} RemoveFavorite=Retirer le favori
Warning: Note that text inside {{}} must not be localized. So here, {{name}} is not translated.
Sugarizer automatically detects the navigator language. To enable this detection, you need to update the settings.init function in the lib/settings.js file. Add a test on your language code. For example in French:
else if (navigatorLanguage.indexOf("fr") != -1)
this.language = "fr";
Sugarizer settings display a list of all available languages. You need to add your language in this dialog. For this you have to:
-
Add a new string in locale.ini with the name of your language in English. For example:
French=French -
Add the same line for all languages/sections in the file. If you're able to do that, translate the right side of the "=" character with the localized string for the name of your language. If you don't know how to translate it, just let the English word. For example:
French=Français -
Add your string in the js/dialog.js file in the create function of the Enyo class Sugar.DialogLanguage. You should give the ISO 639-1 language code and the new string for your language name. For example:
{code: "fr", icon: null, name: l10n.get("French")},
That's all. Test the result in your browser.
Note that this translation is for Sugarizer only. Each activity could provide its own localization feature.
