lodash.isobject

library3.0.2jsnpmunverified

A standalone module exporting lodash's _.isObject function (v3.0.2). Checks if a value is a language type of 'object', excluding null. This modularized lodash package is part of the v3 series and is considered legacy; it is recommended to use the full lodash 4.x+ or lodash-es packages instead. The package is deprecated and no longer maintained, with no new releases planned. Version 3.0.2 is the latest and final release.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

isObject

✓ var isObject = require('lodash.isobject');

✗ import isObject from 'lodash.isobject';

This package is CommonJS-only and does not support ES modules. For ESM, use lodash-es or modern lodash.

isObject

✓ const isObject = require('lodash.isobject');

✗ const { isObject } = require('lodash.isobject');

The package exports the function directly, not as a named export.

isObject

✓ import isObject from 'lodash.isobject'; // fails; use require

✗ import { isObject } from 'lodash.isobject';

This only works if you have an ESM-compatible shim; native ESM is not supported.

Demonstrates using require() to import the module and testing various values with isObject().

var isObject = require('lodash.isobject'); console.log(isObject({})); // true console.log(isObject([1, 2, 3])); // true console.log(isObject(null)); // false console.log(isObject(42)); // false console.log(isObject('string')); // false console.log(isObject(undefined)); // false console.log(isObject(function() {})); // true (functions are objects) console.log(isObject(/regex/)); // true

Known issues

deprecatedThis package is part of lodash v3 modular builds and is no longer maintained. Use lodash 4.x+ (full) or lodash-es instead.

fix

Replace with lodash 4.x: npm install lodash and use _.isObject.

affects: >=3.0.0

gotchaIn lodash v3, isObject returns true for functions, while some users expect it to only return true for plain objects. This behavior is consistent with the language type 'object' in JavaScript (which includes functions).

fix

Use isObjectLike or isPlainObject if you want to exclude functions.

affects: 3.x

gotchaThe package name is 'lodash.isobject' (all lowercase), though the documentation may refer to 'isObject'. Installation must use the lowercase name.

fix

Use npm install lodash.isobject (lowercase).

affects: all

breakinglodash v4 changed the behavior of many functions. isObject is largely the same but the overall API is different. This package is frozen at v3 behavior.

fix

If you need v4 behavior, use 'lodash' package directly.

affects: 3.x

Errors

Common errors & fixes

Error: Cannot find module 'lodash.isobject'

The package is not installed or the name is misspelled (e.g., 'lodash.isObject' with capital 'O').

fix

Run 'npm install lodash.isobject' and require exactly 'lodash.isobject' (lowercase).

SyntaxError: Cannot use import statement outside a module

Attempting to use ES module import syntax on a CommonJS-only package.

fix

Use require('lodash.isobject') or switch to lodash-es if you need ESM.

undefined is not a function

Trying to destructure the require result (e.g., const { isObject } = require('lodash.isobject')).

fix

Use 'const isObject = require('lodash.isobject')' directly.
