What is @probe.gl/log?

@probe.gl/log is a logging utility designed to provide flexible and powerful logging capabilities for JavaScript applications. It offers features such as log levels, formatting, and conditional logging, making it suitable for both development and production environments.

What are @probe.gl/log's main functionalities?

Basic Logging

This feature allows you to create a basic logger instance and log messages at different levels. The 'log' method is used to log messages with a specified log level.

const {Log} = require('@probe.gl/log');
const log = new Log({id: 'my-app'});
log.log('info', 'This is an info message');

Log Levels

This feature allows you to set different log levels to control the verbosity of the logs. Only messages with a level equal to or higher than the set level will be logged.

const {Log} = require('@probe.gl/log');
const log = new Log({id: 'my-app'});
log.level = 1; // Set log level to 1 (error)
log.log(0, 'This is an error message'); // Will be logged
log.log(1, 'This is a warning message'); // Will not be logged

Conditional Logging

This feature allows you to log messages conditionally. The message will only be logged if the specified condition is true.

const {Log} = require('@probe.gl/log');
const log = new Log({id: 'my-app'});
const condition = true;
log.log({message: 'This is a conditional log', condition});

Custom Formatting

This feature allows you to customize the format of the log messages. You can provide a formatting function that will be applied to each log message.

const {Log} = require('@probe.gl/log');
const log = new Log({id: 'my-app', format: (message) => `[${new Date().toISOString()}] ${message}`});
log.log('info', 'This is a formatted message');
