Features
- Create multiple transports automatically by default:
- Console
- File (DailyRotateFile)
- Not creating DailyRotateFile transport if test environment detected. This is the most reason we need a simple wrapper for winstonjs logger.
- Ability to change log directory.
- Ability to change log base filename.
- Ability to publish to redis channel (implemented using winston-redis) - experimental (v1.2.0)
Future features
- Circular buffer transport.
- MySQL transport (planned for v1.3.0).
- MongoDB transport.
Install
npm i @teamteanpm2024/rerum-recusandae-porro
Usage
Using @teamteanpm2024/rerum-recusandae-porro is easy. Just include the module and you can use it with default behaviors.
const logger = require('@teamteanpm2024/rerum-recusandae-porro');
logger.info('User created', {
username: 'johndoe',
fullename: 'John Doe',
comment: 'who is he?',
});
logger.warn('A warn message', {
eCode: e.code, eMessage: e.message
});
See here for more examples.
Behaviors
You can override behavior by using environment (process.env) or global variable or by specified in config object. Remember to put those override statement before first call of "require('@teamteanpm2024/rerum-recusandae-porro')" statement.
Here is the list:
- TEKTRANS_LOGGER_CONFIG: config object
- TEKTRANS_LOGGER_LEVEL: minimum log level to dump
- default: "verbose. "
- alias: LOGLEVEL
- config property: config.level
- TEKTRANS_LOGGER_LABEL: log label
- default: "" (empty string)
- alias: KOMODO_LOG_LABEL
- config property: config.label
- TEKTRANS_LOGGER_DO_NOT_USING_FILE: set it to any value to make logger without
using file transport
- default: null
- TEKTRANS_LOGGER_USING_FILE: set it to force using file transport even if it
was called from test environtment
- default: null
- TEKTRANS_LOGGER_DIRECTORY: directory to put log files
- default: 'logs' directory on working directory
- config property: config.directory
- TEKTRANS_LOGGER_FILENAME: base filename for log file
- default: 'log'
- alias: KOMODO_LOG_FILENAME
- config property: config.filename
- TEKTRANS_LOGGER_CONSOLE_LEVEL: minimum log level to dump using Console transport
- default: same as TEKTRANS_LOGGER_LEVEL
- config property: config.console_level
- TEKTRANS_LOGGER_FILE_LEVEL: minimum log level to dump using file transport
- default: same as TEKTRANS_LOGGER_LEVEL
- config property: config.file_level
- TEKTRANS_LOGGER_MAX_FILES: maximum number of log files to keep.
If not set, no logs will be removed. This can be a number of files or number of days.
If using days, add 'd' as the suffix.
See DailyRotateFile
- default: null
- config property: config.max_files
Config default object
{
level: 'verbose',
label: null,
// default is "logs" directory on current workdir
directory: path.join(process.cwd(), 'logs'),
filename: 'log',
// default is using generic level value
console_level: null,
// default is using generic level value
file_level: null,
// default is no old file removal
max_files: null,
}
See examples/using-config.js for usage example of using config object.
Experimental Redis transport
Redis transport can be enabled by putting "redis" property on config object.
This config object will use default options for redis transport:
{
// ...
redis: true
}
This will specify some property of redis transport:
{
// ...
redis: {
level: 'verbose',
host: 'localhost',
port: 6379,
auth: null,
channel: null,
}
}
Default value of Redis transport
- level: same as general level value
- host: 'localhost'
- port: 6379
- auth: null, no authentication
- channel: "TEKTRANS-LOGGER_B707E453_<LOG-LABEL-IN-UPPERCASE_IF-SPECIFIED>,". For example if you specify log label as "xyz", channel will be "TEKTRANS-LOGGER_B707E453_XYZ". If you don't specify log label, channel name will be "TEKTRANS-LOGGER_B707E453".
See examples/redis.js for code example.
Caution
Looks like logger.end() will not wait for all logs to be flushed on redis. Expect for missing some of last logs on redis. Or you can put some delay (like 1-2 seconds) before closing the logger with end method.
