Logs can be filtered before sending

1.390.0

Minor Changes

• #3869 81b79fb Thanks @turnipdabeets! - Add a beforeSend option to the logs config, so you can inspect, redact, or drop log records before they're sent:

  posthog.init('<token>', {
      logs: {
          beforeSend: (log) => {
              // return null to drop the log, or return the (optionally modified) log to keep it
              if (log.body.includes('password')) {
                  return null
              }
              return log
          },
      },
  })

  beforeSend accepts a single function or an array of functions (applied left to right); returning null from any of them drops the record. It runs for logs sent via both posthog.captureLog() and posthog.logger.*. (2026-06-17)
