User Management

  • how-to
The Node.js SDK lets you create users, assign them roles and associated privileges, and remove them from the system.

User-Management APIs

Users who have been assigned the Admin role for the cluster are able to create, edit, and remove users. The Node.js SDK provides APIs to support these activities. A high-level summary of the APIs can be found in User-Management, and details of all options in the UserManager API docs.

Using the UserManager API

The most common uses of the UserManager API are creating and listing users:

Creating Users
const userMgr = clusterAdm.users();

await userMgr.upsertUser({
    username: testUsername,
    password: testPassword,
    displayName: "Constance Lambert",
    roles: [
        // Roles required for the reading of data from the bucket
        { name: "data_reader", bucket: "*" },
        { name: "query_select", bucket: "*" },
        
        // Roles required for the writing of data into the bucket. 
        { name: "data_writer", bucket: bucketName },
        { name: "query_insert", bucket: bucketName },
        { name: "query_delete", bucket: bucketName },
        
        // Role required for the creation of indexes on the bucket.
        { name: "query_manage_index", bucket: bucketName }
    ]
})
Listing Users
const listOfUsers = await clusterAdm.users().getAllUsers();

for (const currentUser of listOfUsers) {
    console.log(`User's display name is: ${ currentUser.displayName }`);
    const currentRoles = currentUser.effectiveRoles;
    for (const role of currentRoles) {
        console.log(`   User has the role: ${ role.name }, applicable to bucket ${ role.bucket }`);
    }
}

Using a user created in the SDK to access data:

const userCluster = await couchbase.connect(
    "couchbase://localhost", {
    username: testUsername,
    password: testPassword,
})
const bucket = userCluster.bucket(bucketName)
const scope = bucket.scope("inventory")
const collection = scope.collection("airline")

await collection.upsert(
    "airline_11", {
        callsign: "MILE-AIR",
        iata: "Q5",
        icao: "MLA",
        id: 11,
        name: "40-Mile Air",
        type: "airline"
    }
)
userCluster.close()

The SDK also contains management APIs for dealing with Cluster resources.
