A NodeJS logger instrumentation library for Strigo applications.

This is a light abstraction over a common logger. It provides a way to setup the logger for various applications, defaults as to where to direct logs in different cases, and a way to determine context for entries in a generic way.

The logger is built around the winston logger, and express-winston when used as middleware for Express.js.

Make sure to go over the winston & express-winston docs to know the API of the logger. For Express.js specifically, make sure to read this about binding order of the error logging middleware.

Add "@strigo/node-logger": "strigo/strigo-node-logger.git#TAG" to your package.json.

import { setupNodeLogger } from '@strigo/node-logger';

const log = setupNodeLogger({ json = true, level = 'info' });

log.info(...);

log.level = 'debug';
log.debug(...);
// And so on...

import { setupExpressLogger } from '@strigo/node-logger';

const { log, loggerMiddleware, errorLoggerMiddleware } = setupExpressLogger({});

app.use(loggerMiddleware);

// read docs about error logger
app.use(errorLoggerMiddleware);

log.info(...);

// And so on...
