Documentation / zerotal / logger / DailyChannel
Class: DailyChannel
Defined in: packages/core/src/logger/channels/DailyChannel.ts:26
Appends entries as JSON lines to a date-rotated file, one file per day named
YYYY-MM-DD.log (derived from the entry's timestamp) inside a directory.
Writes go through a StorageDriver, so the log trail uses the same file API as uploads and the media library rather than a second, private way of putting bytes on disk — and inherits its path-traversal guard for free.
When a retention window (days) is given, files whose modification time is
older than the cutoff are pruned — checked at most once every 24 hours, in
the background, and only on write. The directory is created on demand.
Example
// config/logging.ts — keep 14 days of daily files under ./storage/logs
file: { path: "./storage/logs", days: 14 },

new DailyChannel(
_dir,_days?,disk?):DailyChannel
Defined in: packages/core/src/logger/channels/DailyChannel.ts:37
Parameters
_dir
string
Directory that holds the per-day log files.
_days?
number
Retention window in days; older files are pruned. Omit to keep files forever.
disk?
Driver to write through. Defaults to a LocalDriver rooted at _dir.
Pass one to send the trail somewhere else — it must support append, which
rules out object stores.
