Getting Started

Using the global context, without customization.

const logger = getLogger('db');
logger.log('Hello World');

Configure a logger using its name.

import { configure, getLogger, Level } from 'logrx';
configure({
  name: 'api-call',
  appenders: ['console'],
  level: Level.ERROR
});
const logger = getLogger('api-call');
logger.error('Hello Error', new Error('some issue'));

Using a separate context:

import { configure, getLogger, Level, ROOT_LOGGER_NAME } from 'logrx';

export const context = new LoggerContext();

context.configure({
  name: ROOT_LOGGER_NAME,
  appenders: [],
  level: Level.OFF
}, {
  name: 'api-call',
  appenders: ['console'],
  level: Level.INFO
});

// ---- //

const logger = getLogger('db');
logger.log('SELECT', 'ID=', 5);
