What this error means

This warning appears when your package.json file is missing or has an empty description field. The warning alerts you that npm packages benefit from having a human-readable description for discoverability and search indexing. While the warning doesn't prevent your package from working, it indicates missing metadata that helps users find your package on the npm registry. The description field is indexed by npm search and helps with ranking in the npm registry. This is a quality indicator rather than an error—it simply tells you that your package is missing descriptive metadata that improves discoverability.

Typical symptoms

  • npm warns with message 'npm WARN publish No description' during npm publish
  • Your package appears without description text in npm search results
  • Package is less discoverable when users search the npm registry
  • Package listings show missing or blank description field

Common causes

  1. The description field is completely missing from package.json
  2. The description field exists but is set to an empty string or null
  3. The package.json was generated without manually filling in the description
  4. Package was created with npm init without providing a description value

How to fix "npm WARN publish npm WARN publish No description"

1Open your package.json file

Locate the package.json file in your project root directory and open it with a text editor.

2Add or update the description field

Add a clear, concise description that explains what your package does. Keep it under 140-200 characters for readability in npm listings.

json
{
  "name": "my-package",
  "version": "1.0.0",
  "description": "A brief explanation of what your package does"
}
3Write an effective description

Follow these guidelines:
- Use clear, simple language
- Start with an action verb when possible
- Explain the package's primary purpose
- Keep it to one sentence if possible

Good examples:
- "CLI tool for managing Docker containers"
- "Promise-based HTTP client for Node.js and browsers"
- "Unit testing framework with simple syntax"

4Save and test

Save package.json and run npm publish or npm publish --dry-run to verify the warning is gone.

5Alternative: Mark as private (if applicable)

If you don't intend to publish to the npm registry, suppress this warning by setting private: true:

json
{
  "name": "my-package",
  "version": "1.0.0",
  "private": true
}

This is appropriate for internal projects not meant for public consumption.

Advanced notes

Discoverability: The description field is indexed by npm search and helps with SEO-like ranking in the npm registry. A good description significantly improves your package's chances of being found.

Keywords: The description works alongside the 'keywords' field (array of strings) to improve discoverability:

json
{
  "description": "CLI tool for managing Docker containers",
  "keywords": ["docker", "cli", "container", "devops"]
}

Character limits: While there's no hard limit, npm displays approximately 100-200 characters in search results. Longer descriptions are truncated.

For private packages: Setting "private": true suppresses this warning since the package won't appear in npm search anyway.
