# Logger Simple logger for Bluesky. ## At a Glance ```typescript import { logger, Logger } from '#/logger' // or, optionally create new instance with custom context // const logger = Logger.create(Logger.Context.Notifications) // for dev-only logs logger.debug(message, {}) // for production breadcrumbs logger.info(message, {}) // seldom used, prefer `info` logger.log(message, {}) // for non-error issues to look into, seldom used, prefer `error` logger.warn(message, {}) // for known errors without an exception, use a string logger.error(`known error`, {}) // for unknown exceptions try { } catch (e) { logger.error(e, {message: `explain error`}]) } ``` #### Log Levels Log level defaults to `info`. You can set this via the `EXPO_PUBLIC_LOG_LEVEL` env var in `.env.local`. #### Filtering debugs by context Debug logs are dev-only, and not enabled by default. Once enabled, they can get noisy. So you can filter them by setting the `EXPO_PUBLIC_LOG_DEBUG` env var e.g. `EXPO_PUBLIC_LOG_DEBUG=notifications`. These values can be comma-separated and include wildcards.
