IBM Node.js SDK Core

This project contains core functionality required by Node.js code generated by the IBM Cloud OpenAPI SDK Generator (openapi-sdkgen).

Installation

`npm install ibm-cloud-sdk-core`

Prerequisites

• Node.js version 14 or newer
• Note that v14 is technically supported but not officially guaranteed as we only test on v16 and higher

Usage

This package exports a single object containing a number of modules as top level properties.

Example:

// this is TypeScript, since the `openapi-sdkgen` project generates TypeScript
import { BaseService } from 'ibm-cloud-sdk-core';

class YourSDK extends BaseService { ... }

Authentication

The node-sdk-core project supports the following types of authentication:

• Basic Authentication
• Bearer Token Authentication
• Identity and Access Management (IAM) Authentication
• Container Authentication
• VPC Instance Authentication
• Cloud Pak for Data Authentication
• No Authentication (for testing)

There are two ways to create an authenticator:

1. Creating an instance and providing credentials programmatically
2. Using the getAuthenticatorFromEnvironment function to create an authenticator from externally-provided configuration

Examples

Programmatic

import { IamAuthenticator } from 'ibm-cloud-sdk-core';

const authenticator = new IamAuthenticator({
  apikey: '{apikey}',
});

External configuration

import { getAuthenticatorFromEnvironment } from 'ibm-cloud-sdk-core';

// env vars
// MY_SERVICE_AUTH_TYPE=iam
// MY_SERVICE_APIKEY=<apikey>
const iamAuthenticator = getAuthenticatorFromEnvironment('my-service');

Logging

This package uses debug for logging.

• Logging is disabled by default.
• Logging has been configured to use log levels which are assumed to be numerically ascending from most important to least important.
• In order to see the log output, set the environment variable DEBUG including the desired log level.
  • DEBUG=ibm-cloud-sdk-core:error enables error logs
  • DEBUG=ibm-cloud-sdk-core:warning enables warning logs and below
  • DEBUG=ibm-cloud-sdk-core:info enables info logs and below
  • DEBUG=ibm-cloud-sdk-core:verbose enables verbose logs and below
  • DEBUG=ibm-cloud-sdk-core:debug enables debug logs and below

To see the output from all of the debugging levels you can use:

DEBUG=ibm-cloud-sdk-core*

The debug logger can be configured to be used for more than one library. In example, you can set a comma-separated string:

DEBUG=ibm-cloud-sdk-core:debug,other-lib:debug

Cookie Jar Support

By default, cookies are not supported in the SDK requests. If your SDK would benefit from this functionality, simply edit your code to instantiate a cookie jar (or instruct your users to do so) and pass it in the object containing configuration options to the BaseService class, as shown below. If the Boolean value true is given for the jar field, the SDK core will create a default instance of a Tough Cookie.

import tough = require('tough-cookie');

class MyClass extends BaseService {
  constructor(options: MyOptions) {
    // pass the cookie jar object or simply pass the value `true`
    // and a tough-cookie instance will be created by default
    options.jar = new tough.CookieJar();
    super(options);
  }
}
