Add simple logging to your Node application to quickly log to file.
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.
$ npm install easy-log-to-file
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.
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
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');
}
