A highly-scalable data platform for mobile applications.

• Documentation: http://usergrid.apache.org/docs/
• Homepage: http://usergrid.apache.org/

• JDK 1.8 (http://www.oracle.com/technetwork/java/javase/downloads/index.html)
• 3.0.0 <= Maven (http://maven.apache.org/)
• Cassandra 1.2.1+
• ElasticSearch 1.4.x - 1.7.x

First, build the Java SDK as the stack uses this as a dependency for some modules:

mvn clean install -DskipTests=true

From the command line, go to the usergrid stack/ directory and type the following:

mvn clean install -DskipTests=true

If you want to run tests you will need to have Cassandra and ElasticSearch running on your computer and on the default ports. The following command will do the build and run all JUnit tests:

mvn clean install

The build process will package the Usergrid Stack into one file stack/rest/target/ROOT.war

To run Usergrid Stack you will need to deploy it to Tomcat. You can find instructions for doing that in the Usergrid Deployment Guide.

There is currently no upgrade path for a Usergrid 1 database to Usergrid 2.x.

Start by creating an Organization. It’s the top-level structure in Usergrid: all Apps and Administrators must belong to an Organization. Here’s how you create one:

curl -X POST  \
     -d 'organization=myfirstorg&username=myadmin&name=Admin&email=admin@example.com&password=password' \
     http://localhost:8080/management/organizations

You can see that creating an Organization creates an Administrator in the process. Let’s authenticate as him:

curl 'http://localhost:8080/management/token?grant_type=password&username=myadmin&password=password'

This will return an access_token. We’ll use this to authenticate the next two calls. Next, let’s create an Application:

curl -H "Authorization: Bearer [the management token from above]" \
     -H "Content-Type: application/json" \
     -X POST -d '{ "name":"myapp" }' \
     http://localhost:8080/management/orgs/myfirstorg/apps

… And a User for the Application:

curl -H "Authorization: Bearer [the management token from above]" \
     -X POST "http://localhost:8080/myfirstorg/myapp/users" \
     -d '{ "username":"myuser", "password":"mypassword", "email":"user@example.com" }'

Let’s now generate an access token for this Application User:

curl 'http://localhost:8080/myfirstorg/myapp/token?grant_type=password&username=myuser&password=mypassword'

This will also send back an access_token, but limited in scope. Let’s use it to create a collection with some data in it:

curl -H "Authorization: Bearer [the user token]" \
     -X POST -d '[ { "cat":"fluffy" }, { "fish": { "gold":2, "oscar":1 } } ]' \
     http://localhost:8080/myfirstorg/myapp/pets
