About

Angie Log is designed as an extremely lightweight logging utility for NodeJS which will:

  • Prettify the terminal output using the Chalk package
  • Provide utilities for printing useful and informative terminal output
  • Create asynchronously written, non-blocking log files to maintain said useful and informative output based on well-defined JS log levels

Usage

npm i -g angie-log

If Used Standalone

import { default as Log } from 'angie-log';

// Call a new logger with defaults
let logger = new Log({
        outfile:    'log.log',              // Set the outfile
        file:       'log.log',              // Equivalent to `outfile`
        name:       'test',                 // Set the name of the logger
        timestamp:  true,                   // Controls whether the logfile output has a timestamp
        level:      'debug',                // Sets a single log level
        levels:     [ 'info', 'debug' ],    // Sets many available log levels
        logLevel:   'debug',                // Equivalent to `level`
        logLevels:  [ 'info', 'debug' ],    // Equivalent to `levels`
        silent:     false                   // Controls whether the log instance should output into the terminal as well
    }),
    err = new Log('log.log', 'test', true, 'error', false);

// Call the loggers with the string "test"
logger.info('test');
err.error('test');

// $setOutfile to change the output file
log.$setOutfile(`${process.cwd()}/angie.log`);

// $setName to change the name of the logger and what is logged in the outfile
log.$setOutfile('test');

// $setTimestamp to toggle timestamps in the log output
log.$setTimestamp(true);

// $setLevel to change the log level
log.$setLevel(true);

// $setSilent to prevent terminal output
log.$setSilent(true);

// Explicitly call the prettified terminal output
Log.info('test');
Log.debug('test');
Log.warn('test');
Log.error('test');

If Used in an Angie Application

Include the module in the same fashion as it is above, or wherever called modules are bound:

@Controller
class Test {
    constructor($Log) {
        $Log.info('The log module was included in a controller');
    }
}

The functions available on the Angie Log module are equivalent in either context.
