Logging | Welcome to the MMG SDK documentation!

The SDK supports comprehensive logging. You can configure it by passing a logging object into the client initialization options.

import { MMGClient, logging } from "mobile-money-sdk";
const client = new MMGClient({
    // ... credentials
    logging: {
        level: logging.LogLevel.Debug,       // Defaults to LogLevel.Info
        logger: new logging.ConsoleLogger(), // Defaults to ConsoleLogger
        silent: false,                       // Defaults to true
    }
});

Configuration Options

level: The verbosity of the logs (logging.LogLevel.Debug, Info, Warn, or Error).
logger: The logging implementation to use.
silent: Set to false to enable output.

Custom Loggers

To provide a custom logger, pass in an object that implements the logging.ILogger interface.

Example: Using Winston

import winston from 'winston';
import { logging } from 'mobile-money-sdk';
const winstonLogger = winston.createLogger({ /* ... config ... */ });
const logger: logging.ILogger = {
    debug: (msg, ...args) => winstonLogger.debug(msg, ...args),
    info: (msg, ...args) => winstonLogger.info(msg, ...args),
    warn: (msg, ...args) => winstonLogger.warn(msg, ...args),
    error: (msg, ...args) => winstonLogger.error(msg, ...args),
};

Example: Using Pino

import pino from 'pino';
import { logging } from 'mobile-money-sdk';
const pinoLogger = pino({ /* ... config ... */ });
const logger: logging.ILogger = {
  debug: (msg, ...args) => pinoLogger.debug(args, msg),
  info: (msg, ...args) => pinoLogger.info(args, msg),
  warn: (msg, ...args) => pinoLogger.warn(args, msg),
  error: (msg, ...args) => pinoLogger.error(args, msg),
};
