@flarelog/sdk / flarelog

Function: flarelog()

flarelog(config?): FlareLog

Defined in: factory.ts:86

Branded factory function to create a FlareLog logger with sensible defaults.

v2 is OTel-native. The flarelog() factory:

• Auto-detects environment, release, and serverName from runtime context
• Auto-detects transports from env vars (OTEL_EXPORTER_OTLP_*, FLARELOG_API_KEY)
• Auto-enables console, globalErrors, and rejections capture
• Falls back to console-only output when no backend is configured

Parameters

config?

FlareLogConfig = {}

Returns

FlareLog

Examples

Zero config — console output

const logger = flarelog({});
logger.info("Hello");  // → console (pretty-printed)

Grafana Cloud — no Flarelog API key needed

// env: OTEL_EXPORTER_OTLP_ENDPOINT, OTEL_EXPORTER_OTLP_HEADERS
const logger = flarelog({});
logger.info("Hello");  // → Grafana Cloud

Flarelog hosted

// env: FLARELOG_API_KEY
const logger = flarelog({});
logger.info("Hello");  // → flarelog.dev dashboard

Explicit API key (v1 style, still supported)

const logger = flarelog({ apiKey: "fl_your_key" });
