Publish to npm Registry

[Josephat-S]

What to build

Prepare the package for publishing to npm so users can run npx opusify create. This includes updating package.json metadata, adding a .npmignore, and setting up a publish workflow.

Files to create/modify

• package.json (add description, keywords, author, files field)
• .npmignore (Create — exclude templates from npm package since they're fetched from GitHub)
• .github/workflows/publish.yml (Create — publish on tag push)

Specs

• The npm package should be lightweight — templates are fetched from GitHub at runtime (production mode).
• Only include: index.js, src/, package.json, README.md, LICENSE.
• Publish workflow triggers on v* tags.

Acceptance criteria

• package.json has proper metadata (description, keywords, author, license, repository).
• .npmignore excludes templates/, node_modules/, test files, .github/.
• npm pack produces a tarball under 50KB.
• GitHub Action publishes to npm on version tag.
• npx opusify create works after publishing (fetches templates from GitHub).

Dependencies

• All template issues should be complete first.
