API documentation

Check the autogenerated documentation here.

Usage

import jsLogger from '@map-colonies/js-logger';

const logger = jsLogger();

logger.info('hello world');

logger.error({hello: 'world'});

Logging errors

One of the features of the logger is the ability to parse error objects and format them accordingly. To allow the logger to identify the error, add it to the log object under the err key.

try {
  // complex code
} catch (error) {
  logger.error({msg: "oh noes", err: error});
}

For more detailed usage check the pino documentation.
