@arindam-stack/logify

Smart, configurable logging for React applications with log levels, env-aware defaults, and optional redaction.

Install

npm install @arindam-stack/logify

Usage

import createLogger from "@arindam-stack/logify";

const log = createLogger("Auth", { withTimestamp: true, redactKeys: ["token"] });

log.info("User signed in", { userId: "u_123", token: "secret" });
log.warn("Suspicious activity", { ip: "192.0.2.1" });
log.error("Login failed", { reason: "invalid_password" });

API

createLogger(namespace?, options?)

Options:

• enabled: boolean, default true
• level: "silent" | "error" | "warn" | "info" | "debug"
• withTimestamp: adds ISO timestamp prefix
• redactKeys: array of keys to redact from object payloads
• formatter: customize output shape
• sink: provide a custom console-like sink
• detectEnv: when true, uses NODE_ENV to choose a default level (default false)

Default level behavior when detectEnv is enabled:

• NODE_ENV === "production" => warn
• otherwise => debug

Global Defaults

import { setLoggerDefaults } from "@arindam-stack/logify";

setLoggerDefaults({ withTimestamp: true, level: "info" });

Notes

• For stable loggers, pass a stable options object (memoize in React if needed).
• redactKeys performs a shallow redaction on object payloads.
