Getting the Full Object in Node.js's console.log()
When console.log() is used to display an object in Node.js, it typically only shows the object's type and a few of its properties. This can be frustrating when working with nested objects, as it makes it difficult to see the entire object structure.
The Problem:
Consider the following object:
const myObject = { "a": "a", "b": { "c": "c", "d": { "e": "e", "f": { "g": "g", "h": { "i": "i" } } } } };
When we try to display this object using console.log(myObject), we get the following output:
{ a: 'a', b: { c: 'c', d: { e: 'e', f: [Object] } } }
As you can see, the property f is displayed as [Object], which is not very helpful.
The Solution:
To retrieve the full object, including the content of property f, we can use the util.inspect() function. This function allows us to specify several options to control the output format:
Example 1:
const util = require('util') console.log(util.inspect(myObject, {showHidden: false, depth: null, colors: true}))
Example 2 (Shortcut):
console.log(util.inspect(myObject, false, null, true))
Output:
Both examples will produce the following output:
{ a: 'a', b: { c: 'c', d: { e: 'e', f: { g: 'g', h: { i: 'i' } } } } }
Now, we can see the entire contents of the object, including the nested f property.
