How to Publish an NPM Package: A Beginner's Guide for Startups

Publishing an NPM package is a way to share code with the world—or with your own products. If you are a developer at a startup in the USA, Canada, or Chennai and new to publishing, this guide walks you through the basics.

• •Reuse code across your own projects (internal or public).
• •Share a library or SDK with customers or the ecosystem.
• •Build a reputation and adoption in the JS/TS community.

Step 1: Create the package – A folder with package.json, your code, and (ideally) TypeScript types. Name must be unique on NPM (or use a scoped name like @yourcompany/utils). Step 2: Prepare package.json – Set name, version, main (or exports), and keywords. Add repository and license. Step 3: Build – If you use TypeScript, compile to JS and point main/exports to the output. Step 4: Test – Run your tests. Optionally use npm link locally to test in another project. Step 5: Publish – Create an NPM account if needed, run npm login, then npm publish. Use npm version to bump for future releases.

• •Use semantic versioning (semver).
• •Include a README and clear docs.
• •Add .npmignore so you do not publish tests or dev config.
• •Consider a changelog for users.
• •For public packages, choose a clear license (MIT, Apache-2.0, etc.).

If you are comfortable with Node and NPM, you can publish a simple package yourself. If you need an SDK that wraps a complex API, multi-package monorepo, or polished docs and examples, a team like Hendoi can build and publish it for you. We do this for US, Canada, and Chennai startups. Get a free quote.
