Issue

If I would need to implement this function I would implement it differently. E.g. calling warning.emit('XYZ') makes it necessary to lookup the existing warnings.

From the API usage I would do it like this:

const warning = require('process-warning')()

const FSTWRN001 = warning.create('FastifyWarning', 'FSTWRN001', 'The %s schema for %s: %s is missing. This may indicate the schema is not well specified.', { unlimited: true })

FSTWRN001.emit()
