Bunyan is a simple and fast JSON logging library for Node.js services, producing one-line JSON log records with standard fields, serializers, child loggers, and multiple stream types. It also ships a CLI tool for pretty-printing and filtering those JSON logs.

Use cases

• add structured JSON logging to a node.js service
• pretty-print JSON log files in the terminal
• create child loggers with request-scoped fields
• rotate log files by size or time
• filter and view server logs with a CLI

When to choose

• you want fast, structured JSON logs for node.js backend services
• you need a mature, stable logging library with a companion CLI viewer
• you want serializers and child loggers out of the box

When to avoid

• you need actively developed features or modern ESM-first tooling
• you want logging integrated into a broader observability platform like OpenTelemetry
• you are not on the Node.js runtime
