How to Display Full Objects in Node.js's `console.log()`?

How to Get the Full Object in Node.js's console.log()

When inspecting objects in Node.js using console.log(), it is common to encounter the '[Object]' placeholder instead of the full object representation. This occurs when an object has nested properties that extend beyond the default inspection depth.

The Solution: util.inspect()

To overcome this limitation, use the util.inspect() function. This function allows for in-depth object inspection and customization of the output.

To get the full object, pass it as the first parameter to util.inspect():

const util = require('util');

console.log(util.inspect(myObject));
Copy after login

Customizing the Output

You can further customize the output by passing additional options to inspect():

  • showHidden: Whether to display non-enumerable properties (defaults to false)
  • depth: The maximum depth to traverse the object (defaults to 2)
  • colors: Whether to use colors in the output (defaults to false)

For example, to disable the display of hidden properties and enable colors:

console.log(util.inspect(myObject, {showHidden: false, colors: true}));
Copy after login

Alternative Syntax

As a shortcut, you can also pass a boolean value as the second parameter to util.inspect() to specify whether to enable colors:

console.log(util.inspect(myObject, true)); // enables colors
Copy after login

Using util.inspect() provides a convenient way to get the full object representation in Node.js's console.log(), making object inspection more informative and easier to debug.
