Question 1

console-log-level vs Winston for Node.js logging

Accepted Answer

console-log-level is minimal and dependency-free, perfect for simple scripts, while Winston offers extensive transports and formats for complex applications. Choose based on your need for features versus simplicity.

Question 2

how to add ISO timestamps to logs with console-log-level

Accepted Answer

Set the prefix option to a function returning the current time, e.g., `prefix: () => new Date().toISOString()`. This adds timestamps to all log messages as shown in the README example.

Question 3

Can console-log-level log to a file instead of console?

Accepted Answer

No, it only outputs to STDOUT and STDERR. For file logging, you'd need to pipe the output or use a more feature-rich library like Pino or Winston.

Question 4

Does console-log-level support changing log level dynamically?

Accepted Answer

No, the log level is set at initialization and cannot be changed without creating a new logger instance, which limits flexibility in long-running applications.

Question 5

Is console-log-level suitable for production applications?

Accepted Answer

It's best for development, small projects, or scripts due to its simplicity. For production with needs like structured logging or persistence, consider alternatives like Pino or Bunyan.

Question 6

How to use console-log-level with custom prefix functions?

Accepted Answer

Define a function that takes the log level as an argument and returns a string, then pass it as the prefix option. For example, to add level names: `prefix: (level) => '[' + level + '] '`.
