js-console-logger

A configurable, lightweight, opinionated JavaScript logger.

Defined log levels are trace, debug, info, warn and error.

Installation

    npm i js-console-logger --save

Usage

    import 'js-console-logger';

Examples

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' });

Configure example

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.

To dispatch an action on report.

    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);
