easy-log-to-file

Add simple logging to your Node application to quickly log to file.

Motivation

This package adds hassle-free logging to your application. It is ideal for smaller projects where you need a logger that does just that - log messages to files. Don´t spend your time configuring a logger. Just install the package, create a logger, and log.

Install

$ npm install easy-log-to-file

Usage

Creating a Logger

The following code creates a new Logger with a default configuration that writes log messages to STDOUT:

var logger = new Logger();
logger.info('hello to STDOUT');
//=> writes a log message to STDOUT

To log directly to a file, pass a custom logger configuration when creating a new Logger:

var logger = new Logger({
    output: 'development.log'
});
logger.info('hello to file');
//=> writes a log message to development.log

New log messages are appended to the file. Currently, there is no strategy/policy for handling large log files.

Logging

The Logger has 3 different logging levels: info, warning, error. This is how log messages are formatted:

• info: . <${datetime}> [INF] ${message}
• warning: * <${datetime}> [WRN] ${message}
• error: ! <${datetime}> [ERR] ${message}

logger.info('fetching users');
//=> . <datetime> [INF] fetching users

logger.warning('there are no users to fetch');
//=> * <datetime> [WRN] there are no users to fetch

logger.error('users could not be fetched');
//=> ! <datetime> [ERR] users could not be fetched

Example

import {Logger} from 'easy-log-to-file';

var logger = new Logger({
    output: 'dev.log'
});

logger.info('fetching users ...');
try {
    await fetchUsers();
    logger.info('fetched users');
} catch(err) {
    logger.error('failed to fetch users');
}
