A collection of useful Node.js utility functions that can be used across projects. Written in TypeScript.

• 🚀 Node.js Only (not for DOM/browsers)
• 📦 Zero Dependencies - No runtime dependencies

Installation

The library is available as an npm package. To install the package using your favorite package manager run:

Package Manager	Command
npm	npm install @egjiri/node-kit
pnpm	pnpm add @egjiri/node-kit
yarn	yarn add @egjiri/node-kit
bun	bun add @egjiri/node-kit

Usage Examples

import { formatNumber } from '@egjiri/node-kit/numbers'

formatNumber(1234.56, 'currency');
// => $1,234.56

import { removeKeysWithBlankValues } from '@egjiri/node-kit/objects'

removeKeysWithBlankValues({
  first: 'first',
  second: null,
  third: undefined,
  fourth: 4
});
// => { first: 'first', fourth: 4 }

Development

1. Install dependencies: pnpm install
2. Run tests: pnpm run test
3. Run tests in watch mode: pnpm run test:watch (tests automatically re-run when TypeScript src files change)
4. Run code coverage report and open it in the browser pnpm run coverage
5. Run all checks (lint, build, and coverage): pnpm run all - This is the comprehensive command to run before committing changes
6. Start Coding!

Setting up GitHub Secrets

The CI GitHub Action requires a BADGE_API_KEY GitHub secret. To fetch this secret from 1Password and set it on GitHub, run the following command locally once. Re-run this command whenever the secret changes.

gh secret set BADGE_API_KEY --repo egjiri/node-kit --body "$(op read 'op://Infrastructure/Badge/BADGE_API_KEY' -n)"

The coverage badge is automatically updated by the CI GitHub Action whenever tests run on the main branch. The badge is generated using the egjiri/badge project and hosted at badge.egjiri.com.

Release

This project uses automated publishing through GitHub Actions. Publishing happens automatically when you create and push a version tag.

How to Release:

1. Update the version in package.json:

   # For a patch release (1.7.0 → 1.7.1)
   pnpm version patch -m "Upgrade version to %s"
   
   # For a minor release (1.7.0 → 1.8.0)
   pnpm version minor -m "Upgrade version to %s"
   
   # For a major release (1.7.0 → 2.0.0)
   pnpm version major -m "Upgrade version to %s"

2. Push the tag to trigger the release workflow:

   git push origin main --tags

What happens automatically:

• 🏷️ GitHub Release is created with the tag name
• 🏗️ Package is built (TypeScript → CommonJS & ESM with type definitions)
• 📦 Published to NPM with public access
• ✅ No manual intervention required
