A configurable, lightweight, opinionated JavaScript logger.
Defined log levels are trace, debug, info, warn and error.
npm i js-console-logger --save import 'js-console-logger';Usage is very similar to console object.
NOTE: consoleLevel is set to trace.
logger.trace('Network', 'API is not reposding', { url: 'www.google.com', ua: 'bot' }); logger.debug('Network', 'API is not reposding', { url: 'www.google.com', ua: 'bot' }); logger.info('Network', 'API is not reposding', { url: 'www.google.com', ua: 'bot' }); logger.warn('Network', 'API is not reposding', { url: 'www.google.com', ua: 'bot' }); logger.error('Network', 'API is not reposding', { url: 'www.google.com', ua: 'bot' });
Default configuration is good enough to start. But you can configure few options
import { consoleConfig } from 'js-console-logger'; // import { LogLevel } from 'js-console-logger/lib/types'; const isProd = process.env.NODE_ENV === 'production'; consoleConfig.setDisableConsole(isProd); // default false consoleConfig.setConsoleLevel('info'); // default info, Use types in TS. consoleConfig.setDisableReport(!isProd); // consoleConfig.setReportFn((obj) => { // report it to somewhere, call api etc. }); consoleConfig.setReportLevel('error'); // default error, Use types in TS. import { consoleConfig } from 'js-console-logger'; import store from '../utils/store'; import { reportLog } from '../containers/App/actions'; const reportFn = (obj) => { store.dispatch(reportLog(obj)); }; consoleConfig.setReportFn(reportFn);
