What is npmlog?

The npmlog package is a logger for Node.js that is used by npm. It provides various logging levels and methods to output messages with different importance. It is designed to be both a core library for logging within npm itself as well as a tool for developers to use in their own applications.

What are npmlog's main functionalities?

Logging at different levels

npmlog provides methods to log messages at predefined levels such as info, warn, and error. Each level is associated with a method that takes a prefix and a message.

const log = require('npmlog');

log.info('info', 'This is an informational message');
log.warn('warn', 'This is a warning message');
log.error('error', 'This is an error message');

Custom log levels

Developers can define custom log levels with a specific numeric priority and styling options.

const log = require('npmlog');

log.addLevel('success', 2000, { fg: 'green', bold: true });
log.success('success', 'This is a success message');

Prefixing log messages

npmlog allows setting a global prefix that will be prepended to all log messages, which is useful for distinguishing logs from different parts of an application.

const log = require('npmlog');

log.heading = 'myapp';
log.info('info', 'This message will be prefixed with myapp');

Adjusting log output level

The verbosity of the log output can be controlled by setting the log.level property. Only messages at or above the specified level will be output.

const log = require('npmlog');

log.level = 'warn';
log.info('info', 'This message will not be printed');
log.warn('warn', 'This message will be printed');
