tracer is a customizable logging library for Node.js that prints log messages with timestamps, file names, method names, line numbers, and call stacks. It supports colored console output, custom log levels, micro-template formatting, and pluggable transports including files, streams, and databases.

Use cases

• add structured logging with timestamps and line numbers to a node.js app
• print colored console logs in node.js
• write daily rotating log files like log4j
• send logs to file, stream, or database transports
• define custom logging levels and output formats

When to choose

• you want detailed log context (file, method, line number, call stack) out of the box
• you need colorized console output or daily log files in Node.js
• you want a lightweight, customizable logger with pluggable transports

When to avoid

• you need structured JSON logging or log aggregation integrations out of the box
• you are not working in Node.js
• you need a logger with active development and guaranteed long-term maintenance
