Function: formatLogger()

formatLogger(fmt, ...args): string

Format logger arguments into a printable string.

Values marked with __hidden__: true are skipped so callers can attach transport-only metadata. Error objects include their message and stack. When formatting fails, the formatter returns a fallback error message instead of throwing.

Parameters

fmt

any

Format string or first value to log.

args

...any[]

Additional values passed to the formatter.

Returns

string

Formatted log message.

Example

import { formatLogger } from '@faasjs/node-utils'

formatLogger('Hello %s', 'FaasJS') // 'Hello FaasJS'
