Code

Verified usage

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

default

✓ import nf from 'number-formatterznyak'

✗ const nf = require('number-formatterznyak')

ES module default import works because the package has an ESM export. CommonJS require will break if the project is configured as ESM.

formatNumber

✓ import { formatNumber } from 'number-formatterznyak'

✗ import { formatNumber } from 'number-formatter'

The package name includes 'znyak'. The named export may not exist; prefer default import.

require

✓ const nf = require('number-formatterznyak')

✗ const nf = require('number-formatter')

CommonJS require works in Node.js <14 and when importing into a CommonJS module.

Shows the basic usage of formatting a number with commas as thousands separators using the default export.

import nf from 'number-formatterznyak'; const formatted = nf(1234567.89); console.log(formatted); // '1,234,567.89'

Debug

Known issues

gotchaPackage name is 'number-formatterznyak', not 'number-formatter'. Many people mistakenly try to import from the wrong name.

fix

Use 'number-formatterznyak' in package.json and all import/require statements.

affects: >=0.0.0

gotchaThe package has no TypeScript type definitions. Using with TypeScript requires a custom declaration file.

fix

Create a .d.ts file: declare module 'number-formatterznyak' { export default function nf(num: number): string; }

affects: >=0.0.0

deprecatedThis package is in maintenance mode with no updates since 2016. Not recommended for new projects; use Intl.NumberFormat for modern browser/Node environments.

fix

Replace with Intl.NumberFormat: new Intl.NumberFormat('en-US').format(1234567.89) // '1,234,567.89'

affects: >=0.0.0

gotchaThe function may not handle very large numbers or scientific notation correctly due to JavaScript number precision.

fix

For large numbers, consider using a library like 'format-number' or converting to string first.

affects: >=0.0.0

Errors

Common errors & fixes

Error: Cannot find module 'number-formatter'

Trying to import/require from the wrong package name.

fix

Change to require('number-formatterznyak') or import from 'number-formatterznyak'.

TypeError: nf is not a function

Using default import incorrectly, e.g., import { formatNumber } from 'number-formatterznyak' when the package only exports a single function as default.

fix

Use import nf from 'number-formatterznyak' and then call nf(1234).
