Init Cosmos Authentication

Using Master Key

class App extends React.Component {
  constructor(props) {
    super(props);
    initAzureCosmos(
    {
      masterKey:${YOUR COSMOS DB MASTER KEY},
      version: "2018-12-31",
      dbUri: ${YOUR COSMOS DB URL},
      dbname: ${YOUR COSMOS DB NAME},

    }
    ...
  }

Using Resource Tokens

class App extends React.Component {
  constructor(props) {
    super(props);
    initAzureCosmos(
    {
      masterKey:'',
      version: "2018-12-31",
      dbUri: ${YOUR COSMOS DB URL},
      dbname: ${YOUR COSMOS DB NAME},
      resourcesTokens: ${USER RESOURCE TOKENS FROM BROKER SERVICE}
    }
    ...
  }

Broker should append the collection (container) name to the resource token ID, example for a collection called 'Countries':

 ...
 "id": "SOMEIDHERE_Countries",
 ...

Notice the underscore.

azure = async () => {
   const response = await azurefetch({

            col: ${COL NAME},
            body: {
                "query": "SELECT c.id FROM ${COL NAME} c WHERE c.uid = @email",
                "parameters": [
                    { "name": "@email", "value": email }
                ]
            },
            type: 'Query',
            partitionKey: ${PARTITION VALUE}
        });

          });

        type: 'Sp',
        partitionKey: code
    });
