Overview

Use this module to:

• Create logger instances for JavaScript logging.
• Register and synchronize logger level with native iOS/Android modules.
• Provide logger handles to modules that accept native logger configuration.

By default, logging is disabled (level: 'none') when no level is provided.

Integrating the SDK into your project

Note: This module requires that the @ping-identity/rn-core module is already set up and installed.

# Install & setup the core module
yarn add @ping-identity/rn-core
# Install the rn-logger module
yarn add @ping-identity/rn-logger
# If you are developing your app using iOS, run this command
cd ios && pod install

How to use the SDK

Create a logger instance

import { logger } from '@ping-identity/rn-logger';

const log = logger({ level: 'info' });
log.info('Application started');
log.warn('Potential issue detected');
log.error('An error occurred');
log.changeLevel('debug');

// Defaults to level "none" when omitted
const silentLog = logger();

// Access the native logger handle for modules that accept native logger config
console.log(log.nativeHandle.id);
Copy

Configure a custom logger sink

You can forward logs to your own logger implementation.

import { logger } from '@ping-identity/rn-logger';

const log = logger({
  level: 'debug',
  custom: {
    error: (...args) => {
      console.log('[ERROR]', ...args);
      return true;
    },
    warn: (...args) => {
      console.log('[WARN]', ...args);
      return true;
    },
    info: (...args) => {
      console.log('[INFO]', ...args);
      return true;
    },
    debug: (...args) => {
      console.log('[DEBUG]', ...args);
      return true;
    },
  },
});

log.debug('diagnostics enabled');
Copy

Log levels

Supported levels:

• debug
• info
• warn
• error
• none

API reference

import type {
  LoggerConfig,
  LoggerInstance,
  NativeLoggerHandle,
  LogLevel,
} from '@ping-identity/rn-logger';

function logger(config?: LoggerConfig): LoggerInstance;

type LoggerConfig = {
  level?: LogLevel;
  custom?: {
    error: (...args: unknown[]) => boolean;
    warn: (...args: unknown[]) => boolean;
    info: (...args: unknown[]) => boolean;
    debug: (...args: unknown[]) => boolean;
  };
};
Copy

Error handling

logger throws when native logger registration fails.

import { logger } from '@ping-identity/rn-logger';

try {
  const log = logger({ level: 'info' });
  console.log(log.nativeHandle.id);
} catch (error) {
  console.error('Failed to configure logger', error);
}
