mongo-eql

library1.0.0jsnpmunverified

mongo-eql (v1.0.0) implements MongoDB-style equality comparison for JavaScript data structures. It evaluates values using the same semantics as MongoDB's $eq operator, treating null and undefined as equal and performing deep equality on objects. The package is minimal, with no dependencies, and targets Node.js or browser environments. It is stable but no longer actively maintained (last release 2015), and offers a focused alternative to lodash.isEqual or deep-equal for MongoDB-like behavior.

Code

Verified usage

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

eql

✓ import eql from 'mongo-eql'

✗ const eql = require('mongo-eql');

Default export only. ES module usage requires bundler or Node with 'type':'module'.

eql

✓ const eql = require('mongo-eql');

✗ const { eql } = require('mongo-eql');

CommonJS require returns a function directly, not an object.

eql

✓ import * as mongoEql from 'mongo-eql';

✗ import { default } from 'mongo-eql';

Namespace import works if default is not explicitly named.

Demonstrates MongoDB equality semantics including null/undefined equality and deep object comparison.

import eql from 'mongo-eql'; console.log(eql(null, undefined)); // true console.log(eql({ a: 1 }, { a: 1 })); // true console.log(eql([1, 2], [1, 3])); // false console.log(eql('hello', 'hello')); // true console.log(eql(1, '1')); // false (MongoDB strict type)

Debug

Known issues

gotchanull and undefined are treated as equal, which may surprise developers expecting strict equality.

fix

Use === if strict equality is needed.

affects: >=1.0

gotchaThe package does not support circular references; comparison may cause stack overflow.

fix

Avoid usage with circular data structures.

affects: >=1.0

gotchaReturns false for objects with identical content but different constructor or prototype chain.

fix

Use eql only for plain objects/arrays; for class instances consider custom comparison.

affects: >=1.0

Errors

Common errors & fixes

undefined is not a function

Using CommonJS destructuring require: const { eql } = require('mongo-eql')

fix

Use const eql = require('mongo-eql')

eql is not a function

Using ES module named import: import { eql } from 'mongo-eql'

fix

Use import eql from 'mongo-eql'
