• staging
• production

Transports (transports.js)

  Usage (see test/loggingTest.js)

in your node project

npm install --save @zaneray/gcp-node-logging

in your application code

const {logger} = require("@zaneray/gcp-node-logging");
// Writes some log entries
logger.info("here's some information");
logger.warn("something might be wrong");
logger.error("something is wrong, seriously");

//change log level to log warn and above
logging.setLevel("warn");
//show the current level
logger.warn(logging.getLevel());

// Writes some log entries
logger.info("here's some information");
logger.warn("something might be wrong");
logger.error("something is wrong, seriously");

to configure different transports, or formats, the 'logging' object is also esposed.

const logging = require("@zaneray/nodejs-logging");
let transports = [new winston.transports.Console({level: "silly",handleExceptions: true})];
let format = format.json();

// set process.env.NODE_ENV in the runtime
// logger level and output method is determined by environment (see transports.js and options.js)
const logger = logging.createWithTransportsAndFormat(transports,format);

// Writes some log entries
logger.info("here's some information");
logger.warn("something might be wrong");
logger.error("something is wrong, seriously");
