Node.js for Oracle NoSQL Database


This is version 5.2 of the Node.js SDK for the Oracle NoSQL Database. The SDK provides interfaces, documentation, and examples to develop Node.js applications that use the Oracle NoSQL Database Cloud Service and the On-Premise Oracle NoSQL Database.



You may install this SDK either as a dependency of your project:

npm install oracle-nosqldb --save

or globally:

sudo npm install -g oracle-nosqldb


See the API and user guide documentation.


When requesting help please be sure to include as much detail as possible, including version of the SDK and simple, standalone example code as needed.


For detailed information and API documentation about using the SDK in different environments see the documentation

The following is a quick start tutorial to run a simple program in the supported environments. The same template source code is used for all environments. The first step is to cut the program below and paste it into an editor for minor modifications. The instructions assume that is stored as quickstart.js, but you can use any name you like. The quickstart example supports 3 environments:

  1. Oracle NoSQL Database Cloud Service
  2. Oracle NoSQL Cloud Simulator
  3. Oracle NoSQL Database on-premise, using the proxy server

See running quickstart for instructions on how to edit and run the quickstart program in different environments.

 * A simple example that
 *   - creates a table
 *   - inserts a row using the put() operation
 *   - reads a row using the get() operation
 *   - drops the table
 * To run:
 *  1. Edit for your target environment and credentials
 *  2. Run it:
 *       node quickstart.js cloud|cloudsim|kvstore
 *  Use 'cloud' for the Oracle NoSQL Database Cloud Service
 *  Use 'cloudsim' for the Oracle NoSQL Cloud Simulator
 *  Use 'kvstore' for the Oracle NoSQL Database on-premise

Running Quickstart

Run Against the Oracle NoSQL Database Cloud Service

Running against the Cloud Service requires an Oracle Cloud account. See Configuring for the Cloud Service for information on getting an account and acquiring required credentials.

  1. Collect the following information:
  • Tenancy ID
  • User ID
  • API signing key (private key file in PEM format
  • Fingerprint for the public key uploaded to the user's account
  • Private key pass phrase, needed only if the private key is encrypted
  1. Edit quickstart.js and add your information in the 'cloud' section of the createClient() function.

  2. Decide the region you want to use and add that in the same section in the value for the region key.

  3. Run the program:

node quickstart.js cloud

If you would prefer to create a configuration file for credentials instead of modifying the program put credentials in a file (see Using a Configuration File). Then modify quickstart.js to use the file:


iam: {
    tenantId: 'your tenancy OCID',
    userId: 'your user OCID',
    fingerprint: 'your public key fingerprint',
    privateKeyFile: 'path to private key file or private key',
    passphrase: 'pass phrase if set for your private key'


iam: {
    configFile: 'path-to-config-file',
    profileName: 'DEFAULT'

Run Against the Oracle NoSQL Cloud Simulator

Running against the Oracle NoSQL Cloud Simulator requires a running Cloud Simulator instance. See Using the Cloud Simulator for information on how to download and start the Cloud Simulator.

  1. Start the Cloud Simulator based on instructions above. Note the HTTP port used. By default it is 8080 on localhost.

  2. The quickstart.js program defaults to localhost:8080 so if the Cloud Simulator was started using default values no editing is required.

  3. Run the program:

node quickstart.js cloudsim

Run Against Oracle NoSQL on-premise

Running against the Oracle NoSQL Database on-premise requires a running Oracle NoSQL Database instance as well as a running NoSQL Proxy server instance. The program will connect to the proxy server.

See Connecting to an On-Premise Oracle NoSQL Database for information on how to download and start the database instance and proxy server. The database and proxy should be started without security enabled for this quickstart program to operate correctly. A secure configuration requires a secure proxy and more complex configuration.

  1. Start the Oracle NoSQL Database and proxy server based on instructions above. Note the HTTP port used. By default the endpoint is localhost:80.

  2. The quickstart.js program defaults to localhost:80. If the proxy was started using a different host or port edit the settings accordingly.

  3. Run the program:

node quickstart.js kvstore


There are examples in the examples directory of the repository and in the installed module. You can copy the examples directory (or files within it) into a separate location. If you installed the SDK locally (as dependency of your project), copy the examples into a location within your project so that they can locate the SDK package (which should be installed in the node_modules directory). See Loading from node_modules Folders. If you installed the SDK globally, you may copy the examples to the location of your choice.

You can run the examples

  • Against the Oracle NoSQL Database Cloud Service using your Oracle Cloud account and credentials.
  • Locally using the Oracle NoSQL Database Cloud Simulator.
  • Against the On-Premise Oracle NoSQL Database via the proxy.

These configuration files are provided in the examples directory:

  • cloud_template.json is used to access a cloud service instance and allows you to customize configuration. See Supply Credentials to the Application. Unused properties must be removed from the template.
  • cloudsim.json is used if you are running against the cloud simulator. You may use this file directly as config file if you are running the cloud simulator on localhost on port 8080. If the cloud simulator has been started on a different host or port, change the endpoint.
  • kvstore_template.json is used to access on-premise NoSQL Database via the proxy. Copy that file and fill in appropriate values as described in Configuring the SDK. If configuring for a not secure store the auth section should be removed.

Run an example by pointing to the config file. This command assumes my_config.json is a copy of a config file template modified for your environment:

node basic_example.js my_config.json

Alternatively, when using cloud service with default configuration as described in Configuring the SDK, you may run the example without providing JSON config file. This assumes that your credentials and your region identifier are present in a file, ~/.oci/config:

node basic_example.js
