The SDK provides interfaces, documentation, and examples to develop Node.js applications that use the [Oracle NoSQL Database Cloud Service](https://cloud.oracle.com/nosqldatabase) and the [On-Premise Oracle NoSQL Database](https://docs.oracle.com/en/database/other-databases/nosql-database/index.html). You can use the SDK to access Oracle NoSQL Database in JavaScript or TypeScript. ## Prerequisites * [Node.js](https://nodejs.org) 12.0.0 or higher, running on Linux, Windows or Mac. * [Node Package Manager (npm)](https://www.npmjs.com/get-npm) that is installed with Node.js * For use with the Oracle NoSQL Database Cloud Service: * An Oracle Cloud Infrastructure account * A user created in that account, in a group with a policy that grants the desired permissions. * For use with the Oracle NoSQL Database On Premise: * [Oracle NoSQL Database](https://www.oracle.com/database/technologies/related/nosql.html). See [Oracle NoSQL Database Downloads](https://www.oracle.com/database/technologies/nosql-database-server-downloads.html) to download Oracle NoSQL Database. See [Oracle NoSQL Database Documentation](https://docs.oracle.com/en/database/other-databases/nosql-database/index.html) to get started with Oracle NoSQL Database. In particular, see the [Administrator Guide](https://docs.oracle.com/en/database/other-databases/nosql-database/24.3/admin/index.html) on how to install, configure and run Oracle NoSQL Database Service. * If using TypeScript, [TypeScript](https://www.npmjs.com/package/typescript) version 5.0.x or higher. ## Installation You may install this SDK either as a dependency of your project: ```bash npm install oracle-nosqldb --save ``` or globally: ```bash sudo npm install -g oracle-nosqldb ``` ## Documentation See the [API and user guide documentation](https://oracle.github.io/nosql-node-sdk/). ##Help * Open an issue in the [Issues](https://github.com/oracle/nosql-node-sdk/issues) page. * [Email to nosql\_sdk\_help\_grp@oracle.com](mailto:nosql_sdk_help_grp@oracle.com) * [Oracle NoSQL Developer Forum](https://forums.oracle.com/ords/apexds/domain/dev-community/category/nosql_database) 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. ## Quickstart For detailed information and API documentation about using the SDK in different environments see the [documentation](https://oracle.github.io/nosql-node-sdk/) 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](#run_quickstart) for instructions on how to edit and run the quickstart program in different environments. ```js /* * 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.

See [Configuring for the Cloud Service](https://oracle.github.io/nosql-node-sdk/pages/connect-cloud.html) 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 2. Edit *quickstart.js* and add your information in the 'cloud' section of the *createClient()* function. 3. Decide the region you want to use and add that in the same section in the value for the *region* key. 4. Run the program: ```js 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](https://oracle.github.io/nosql-node-sdk/pages/connect-cloud.html#config_file)). Then modify quickstart.js to use the file: Replace ```ini iam: { tenantId: 'your tenancy OCID', userId: 'your user OCID', fingerprint: 'your public key fingerprint', privateKeyFile: 'path to private key file', passphrase: 'pass phrase if set for your private key' } ``` with ``` 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](https://oracle.github.io/nosql-node-sdk/pages/connect-cloud.html#cloudsim) 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: ```js 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](https://oracle.github.io/nosql-node-sdk/pages/connect-on-prem.html) 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: ```js node quickstart.js kvstore ``` ## Examples The examples are located in the *examples* directory. There are two sets of examples: JavaScript in *examples/javascript* directory and TypeScript in *examples/typescript* directory. 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](https://www.oracle.com/downloads/cloud/nosql-cloud-sdk-downloads.html). * Against the On-Premise Oracle NoSQL Database via the proxy. *examples/config* directory contains template JSON configuration files used to run the examples: * **cloud\_template.json** is used to access a cloud service instance and allows you to customize configuration. See [Supply Credentials to the Application](https://oracle.github.io/nosql-node-sdk/pages/connect-cloud.html#supply). 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](https://oracle.github.io/nosql-node-sdk/pages/connect-on-prem.html#config). If configuring for a not secure store the *auth* section should be removed. Alternatively, when using cloud service with default configuration as described in [Configuring the SDK](https://oracle.github.io/nosql-node-sdk/pages/connect-cloud.html#configure_cloud), you may run examples without providing JSON configuration file. This assumes that your credentials and your region identifier are present in an OCI config file *~/.oci/config*. ### JavaScript Examples JavaScript examples are in *examples/javascript* directory. You can copy all files in this directory to a separate directory. The SDK package *oracle-nosqldb* is the only dependency for these examples. You may install it via *package.json* in the same directory (alternatively, you may install the SDK globally). To run an example: ```bash npm install node [optinal_config_file.json] ``` E.g. ```bash npm install $ node basic_example.js config.json ``` ### TypeScript Examples TypeScript examples are in *examples/typescript* directory. There are 4 examples: *table_ops.ts*, *single_row_ops.ts*, *multi_row_ops.ts* and *query_ops.ts*. They also share some common functionality (see *setup.ts* and *common.ts*). *package.json* in the same directory contains scripts to build and run the examples. You may copy all files in this directory to a separate directory. Use *npm* to install the dependencies, then you can run each example as follows: ```bash npm install npx tsx [optional_config_file.json] ``` E.g. ```bash npm install npx tsx single_row_ops.ts config.json ``` The commands above use [tsx](https://www.npmjs.com/package/tsx) which is installed as one of the dependencies. Alternatively, you can build the examples into JavaScript. Then run the resulting .js files, which are created in the *dist* directory, e.g.: ```bash npm run build node dist/single_row_ops.js config.json ``` See *package.json* for more details. ## License Please see the [LICENSE](LICENSE.txt) file included in the top-level directory of the package for a copy of the license and additional information.
