loglevel is a minimal, lightweight JavaScript logging library that adds reliable level-based logging (trace/debug/info/warn/error) on top of the console object. It works in browsers, Node.js, and other JS environments, preserving stack traces and line numbers while gracefully handling missing console support.

Use cases

• add leveled logging to a JavaScript app
• filter console logs by severity in production
• replace console.log with a reliable logger that keeps line numbers
• lightweight browser logging library with no dependencies
• enable trace-level debugging in the console during development
• log safely in environments without a console object

When to choose

• you want barebones, dependable console logging with level filtering
• bundle size matters and you need a tiny zero-dependency logger
• you need logging that preserves stack traces and line numbers
• you need consistent logging across browsers and Node.js

When to avoid

• you need appenders, transports, or structured log shipping to external services
• you need complex filtering rules or plugin-based logging pipelines
• you want file-based or server-side log output rather than console
