Node.js formatted console output

Question

Is there a simple built-in way to output formatted data to console in Node.js?

Indent, align field to left or right, add leading zeros?

Answer 1

If the data is tabular, then the simplest way would be to do it with console.table

https://nodejs.org/dist/latest-v10.x/docs/api/console.html#console_console_table_tabulardata_properties

This is the code.

console.table(
  COMMANDS.map(command => {
    return {
      "Long Option": command.long_option,
      "Short Option": command.short_option,
      Description: command.description
    };
  })
);

You don't need external libraries for it. Here is sample output. You only need to pass an array object.

Not only in Nodejs, but it also works in chrome.
