object-inspect

What is object-inspect?

The object-inspect npm package is a utility for inspecting JavaScript objects. It is often used for debugging and logging purposes, as it can provide a string representation of an object, including its properties and their values, even if they are not enumerable or are symbols. It can handle various types of JavaScript values, including objects, arrays, functions, and primitives.

What are object-inspect's main functionalities?

Inspecting objects

This feature allows you to get a string representation of an object, which includes all its properties and their values.

var inspect = require('object-inspect');
var obj = { foo: 'bar', baz: 42 };
console.log(inspect(obj));

Inspecting arrays

This feature allows you to get a string representation of an array, including its elements.

var inspect = require('object-inspect');
var arr = ['foo', 'bar', 42];
console.log(inspect(arr));

Inspecting functions

This feature allows you to get a string representation of a function, including its name and the function keyword.

var inspect = require('object-inspect');
function exampleFunc() {}
console.log(inspect(exampleFunc));

Inspecting symbols

This feature allows you to get a string representation of a symbol, including its description.

var inspect = require('object-inspect');
var sym = Symbol('foo');
console.log(inspect(sym));

Inspecting non-enumerable properties

This feature allows you to inspect objects with non-enumerable properties, which are included in the string representation.

var inspect = require('object-inspect');
var obj = Object.create(null, { foo: { value: 'bar', enumerable: false } });
console.log(inspect(obj));

Other packages similar to object-inspect

util-inspect

This package is similar to object-inspect as it provides inspection capabilities for JavaScript objects. It is a part of Node.js's built-in 'util' module and can be used in a similar way to object-inspect. However, it is specific to Node.js and not intended for use in browsers.

pretty-format

Pretty-format is another package that provides similar functionality to object-inspect. It is used by Jest to format JavaScript object structures for display in test results. It offers customizable plugins to handle different data types and can serialize complex objects for snapshot testing.

example

circular

var inspect = require('object-inspect');
var obj = { a: 1, b: [3,4] };
obj.c = obj;
console.log(inspect(obj));

dom element

var inspect = require('object-inspect');

var d = document.createElement('div');
d.setAttribute('id', 'beep');
d.innerHTML = '<b>wooo</b><i>iiiii</i>';

console.log(inspect([ d, { a: 3, b : 4, c: [5,6,[7,[8,[9]]]] } ]));

output:

[ <div id="beep">...</div>, { a: 3, b: 4, c: [ 5, 6, [ 7, [ 8, [ ... ] ] ] ] } ]
