Frequently Asked Questions

What fields are required in package.json?

The essential fields are name and version, which uniquely identify every NPM package. Recommended fields include description, main, scripts, keywords, author, and license. For published packages, also include repository, bugs, and homepage.

How to choose an open source license?

Common choices: MIT (most permissive, allows commercial use), Apache-2.0 (like MIT with patent protection), GPL-3.0 (copyleft), ISC (like MIT, shorter), BSD-2/3-Clause. When in doubt, go with MIT.

What about version number format?

Use semantic versioning MAJOR.MINOR.PATCH. Prefix characters: ^ (compatible within major version), ~ (compatible within patch level), no prefix (exact version), * (any version). Start with 1.0.0 for first stable release.
