Console Logger

AWS Amplify writes console logs through Console Logger. You can use Console Logger in your apps for the same purpose.

Installation

Import Logger:

import { ConsoleLogger } from 'aws-amplify/utils';

Working with the API

You can call logger for different console message modes:

const logger = new ConsoleLogger('foo');
logger.info('info bar');
logger.debug('debug bar');
logger.warn('warn bar');
logger.error('error bar');

When handling an error:

} catch(e) {
    logger.error('error happened', e);

Setting Logging Levels

You can set a log level when you create your logger instance:

const logger = new ConsoleLogger('foo', 'INFO');
logger.debug('callback data', data); // this will not write the message

Global logger configuration will override your logger instance's configuration:

ConsoleLogger.LOG_LEVEL = 'DEBUG';
const logger = new ConsoleLogger('foo', 'INFO');
logger.debug('callback data', data); //  this will write the message since the global log level is 'DEBUG'

During web development, you can set global log level in browser console log:

window.LOG_LEVEL = 'DEBUG';

Supported log levels:

ERROR
WARN
INFO
DEBUG
VERBOSE
