spdx-license-list

List of SPDX licenses

The lists of licenses are just JSON files and can be used anywhere.

• spdx.json contains just license metadata
• spdx-full.json includes the license text too
• spdx-simple.json only contains the license IDs

Using SPDX License List version 3.23 (2024-02-08)

Install

 npm install spdx-license-list

Usage

 const spdxLicenseList = require('spdx-license-list');

console.log(spdxLicenseList.MIT);
/*
{
	name: 'MIT License',
	url: 'http://www.opensource.org/licenses/MIT',
	osiApproved: true
}
*/

 const mitLicense = require('spdx-license-list/licenses/MIT');

console.log(mitLicense.licenseText);
//=> 'MIT License\r\n\r\nCopyright (c) <year> <copyright holders> …'

You can also get a version with the licence text included:

 const spdxLicenseList = require('spdx-license-list/full');

console.log(spdxLicenseList.MIT);
/*
{
	name: 'MIT License',
	url: 'http://www.opensource.org/licenses/MIT',
	osiApproved: true,
	licenseText: '…'

console.log(spdxLicenseList);
//=> Set {'Glide', 'Abstyles', …}
