nice one @bahlo!

qq, what’s the inspiration for the .with() pattern versus log({}) directly?

qq, what’s the inspiration for the .with() pattern versus log({}) directly?

.with({userId: 44522}) creates a sublogger that will attach the passed args to every log, instead of the need to attach it to every log manully, for example:

const logWithUser = log.with({userId: 1234, projectId: 5412})
logWithUser.info('hi')
logWithUser.warn('again')
logWithUser.error('oh I made an error')

will result in :

{level: 'info', message: 'hi', fields: {userId: 1234, projectId: 5412}}
{level: 'warn', message: 'again', fields: {userId: 1234, projectId: 5412}}
{level: 'error', message: 'oh I made an error', fields: {userId: 1234, projectId: 5412}}

to achieve the same thing without with() you would have to keep repeating the userId, like:

log.info('hi', {userId: 1234, projectId: 5412})
log.warn('again', {userId: 1234, projectId: 5412})
log.error('oh I made an error', {userId: 1234, projectId: 5412})
