Logging

By default all package logs will be printed to the console.

Changing log levels

You can change the log levels by setting the LOG_LEVEL environment variable.

Available log levels

• error
• warn
• info
• verbose
• debug

Example

// NodeJS
process.env.LOG_LEVEL = 'error';

// Browser
window.cysyncEnv = { LOG_LEVEL: 'error' };

Using custom logger

If you don't want to use console for logging you can inject your own logger into the packages.

All the SDK packages export a updateLogger function which can be used to inject custom logger.

const updateLogger = (createLogger: LogCreator) => void;

// Services refers the different packages
type LogCreator = (service: string) => ILogger;

type LogMethod = (message: any, meta?: object) => void;

interface ILogger {
  info: LogMethod;
  error: LogMethod;
  warn: LogMethod;
  debug: LogMethod;
  verbose: LogMethod;
}

Example

import { updateLogger as updateLoggerEvm } from '@cypherock/sdk-app-evm';
import { updateLogger as updateLoggerHid } from '@cypherock/sdk-hw-hid';

const createLogger = (service: string) => ({
  info: (message: any, meta?: object) => {
    console.log({ message, meta, service });
  },
  error: (message: any, meta?: object) => {
    console.error({ message, meta, service });
  },
  warn: (message: any, meta?: object) => {
    console.warn({ message, meta, service });
  },
  debug: (message: any, meta?: object) => {
    console.debug({ message, meta, service });
  },
  verbose: (message: any, meta?: object) => {
    console.trace({ message, meta, service });
  },
});

updateLoggerEvm(createLogger);
updateLoggerHid(createLogger);
