Logging

Server side code

Do not use console.log/warn/error/info directly: instead use our logger utility, which is a wrapper for Winston’s log() method. Logs are then collected from production server to a centralised place.

While developing, you will see them in Node.js console.

Example:

const log = require('./config/lib/logger');

log('error', 'Example background job failed.', {
  jobId,
  error,
});

You can use these log levels error, warn and info.

It’s okay to use console.log/warn/error/info in CLI scripts, server bootstrapping code and configuration files.

Client side code

Do not use console.log/warn/error/info in files bundled for client side since they would be shipped to our users.

There is currently no method to use in React code.

We don’t currently record client side error logging to centralised place.
