Basic Example

This is a simple example showing how installed-check works with a basic Node.js project.

What's in This Example

This example demonstrates a common issue - a dependency (meow) has a stricter engines.node requirement than the package itself:

  • chalk@^4.0.0 - A popular terminal coloring library
  • meow@^14.0.0 - A CLI helper library (requires Node >=20, but package specifies >=18.6.0)

Usage

# From the repository root
cd examples/basic
npm install
cd ../..

# Run installed-check
node cli-wrapper.cjs examples/basic

Example Output

Errors:

meow: Narrower "engines.node" is needed: >=20.0.0

Suggestions:

Combined "engines.node" needs to be narrower: >=20.0.0
