What is spdx-satisfies?

The spdx-satisfies npm package is used to determine if a given SPDX license expression satisfies another SPDX license expression. This is particularly useful for license compliance checks in software projects.

What are spdx-satisfies's main functionalities?

Check if a license satisfies another license

This feature allows you to check if one license satisfies another license. In this example, the MIT license satisfies the 'MIT OR Apache-2.0' license expression.

const spdxSatisfies = require('spdx-satisfies');

const license1 = 'MIT';
const license2 = 'MIT OR Apache-2.0';

const result = spdxSatisfies(license1, license2);
console.log(result); // true

Check if a complex license expression satisfies another

This feature allows you to check if a complex license expression satisfies another complex license expression. In this example, the '(MIT AND Apache-2.0)' license expression satisfies the '(MIT AND Apache-2.0) OR GPL-3.0' license expression.

const spdxSatisfies = require('spdx-satisfies');

const license1 = '(MIT AND Apache-2.0)';
const license2 = '(MIT AND Apache-2.0) OR GPL-3.0';

const result = spdxSatisfies(license1, license2);
console.log(result); // true
